-## Goal
+## Objective
 
-Yoi が MCP (Model Context Protocol) server を external capability provider として安全に扱えるようにする。
+Add MCP local stdio integration to Yoi without weakening Worker history, prompt-context, scoped tool permission, or Plugin/Feature layering invariants.
 
-到達点は、MCP server が提供する tools / resources / prompts を、Yoi の既存の Pod / Feature / ToolRegistry / permission / scope / history / bounded result 境界に乗せて利用できる状態にすること。MCP は Yoi の plugin model そのものではなく、protocol-bound bridge / external provider runtime として扱う。
+MCP should be implemented as a protocol-backed integration layer on top of `pod::feature`. `pod::feature` supplies the contribution/lifecycle API substrate; MCP owns its own enablement, local server trust model, command/env/secret policy, and MCP-specific permissions. MCP is not the Plugin model, and Plugin permission policy is not implemented by feature-layer authority grants.
 
-## Motivation / background
+## Strategic direction
 
-MCP は AI application と外部 system を接続する標準 protocol になりつつあり、server は tools、resources、prompts などを提供する。Yoi にとって MCP support は有用だが、外部 server が返す schema、description、annotation、resource content、prompt template はすべて untrusted data であり、Yoi の instruction hierarchy、scope、permission、history persistence、prompt-context 加工原則を弱めてはいけない。
+- Baseline the implementation on MCP specification `2025-11-25`.
+- Start with local stdio MCP servers only.
+- Treat MCP server metadata, tools, resources, prompts, and results as untrusted content.
+- Do not allow MCP resources/prompts to be hidden context injection.
+  - They must be explicit tool operations with history records.
+- Use the normal Yoi tool registry, PreToolCall permission, history, and bounded result paths.
+- Do not add private MCP-only bypasses around Worker/tool invariants.
+- Keep sampling and elicitation fail-closed initially.
+- Keep Streamable HTTP, remote auth, OAuth, and MCP Registry/distribution out of the first slice.
+- Treat local stdio server execution as an explicit MCP config/trust decision, not as a `pod::feature` authority grant.
+- Document clearly that a configured local MCP server runs as a local executable; Yoi feature authority does not sandbox its OS-level side effects.
 
-現行の `pod::feature` API は static descriptor / static tool contribution を中心にしており、MCP のように startup 時の initialize / capability negotiation / discovery によって surface が決まる provider には不足がある。そのため、MCP 実装だけを先に ad-hoc に入れるのではなく、まず外部 protocol-backed provider を扱える Feature API boundary を整え、その上に MCP implementation を載せる。
+## Layering decisions
 
-## Strategy / design direction
+- `pod::feature` is an API/contribution substrate.
+  - It owns contribution declarations, provider/service lifecycle hooks, diagnostics, dynamic registration plumbing, and integration with normal Worker/ToolRegistry paths.
+  - It does not own Plugin permission policy or MCP server trust policy.
+- Plugin is a user-facing package/config/runtime layer over `pod::feature`.
+  - Plugin permissions are Plugin-layer policy.
+  - Plugin package discovery/enablement must not be conflated with MCP local server execution.
+- MCP is a separate feature-backed integration layer.
+  - MCP enablement, command/env/secret handling, server trust, and MCP-specific permission decisions live in MCP config/implementation.
+  - MCP dynamic tools/resources/prompts are exposed through the feature API and ordinary Yoi tool paths.
 
-- Broad MCP integration Ticket は progress-container として使わず、この Objective に中期方針を移す。
+## Work breakdown
-- 実装 work item は concrete Ticket に分ける。
-  - `00001KTR81P9X`: `pod::feature` / Worker / ToolRegistry API を external protocol-backed provider に耐える形へ拡張する。
-  - `00001KTR82RB7`: MCP `2025-11-25` local stdio server-feature bridge を実装する。
-- MCP 実装は local stdio transport から始める。
-  - Streamable HTTP、remote auth/OAuth、MCP Registry distribution、workspace-provided package auto-start は後続判断とする。
-- tools / resources / prompts は無理に分けず、MCP server features として扱う。
-  - ただし resources/prompts は direct context injection ではなく、明示 tool operation の結果として history に残す。
-  - `resources/read` / `prompts/get` の結果を history に残らない形で context に注入しない。
-- MCP server は untrusted external capability provider として扱う。
-  - server-provided schema/description/annotation/content/error は instruction ではなく data。
-  - ToolRegistry / PreToolCall permission / history / bounded result path を迂回しない。
-- local process execution は explicit authority として扱う。
-  - filesystem/network authority から暗黙に subprocess 起動権限を派生させない。
-  - secrets は explicit secret/env references で扱い、diagnostics / logs / model context / project records に plaintext として残さない。
-- dynamic discovery / list_changed は prompt/tool schema consistency を壊さない範囲で扱う。
-  - live refresh が危険なら next-turn refresh または restart/reinitialize-required diagnostic を選ぶ。
-  - silent stale state は避ける。
-- Sampling / elicitation は external server が Yoi 側の LLM/user interaction を要求する強い authority なので、初期段階では fail-closed とし、必要なら別 Ticket で approval/resume/UI path を設計する。
 
-## Success criteria / exit conditions
+1. `00001KTR81P9X` — Extend `pod::feature` API for protocol-backed external providers.
+   - provider/service lifecycle
+   - startup discovery and dynamic contribution registration
+   - bounded refresh semantics
+   - metadata/result normalization
+   - no feature-layer authority model for MCP/Plugin permissions
+2. `00001KTR82RB7` — Implement MCP `2025-11-25` local stdio server bridge.
+   - explicit MCP config and trust model
+   - initialize/capability negotiation
+   - tools/resources/prompts list/call/read/get
+   - bounded result serialization
+   - list-changed diagnostics/refresh behavior
+3. `00001KV0SP0TY` — Remove feature-layer HostAuthority model.
+   - remove authority/grant terminology from `pod::feature`
+   - keep real permission/trust policy in owning Plugin/MCP/manifest/tool layers
+4. Later follow-ups, if needed.
+   - richer MCP tasks / task-support integration
+   - remote/HTTP transports
+   - OAuth / registry / package distribution
+   - Plugin package/runtime alignment, if an explicit MCP/plugin bridge is later approved
 
-- `pod::feature` が external protocol-backed capability provider を表現できる。
+## Success criteria
-- local subprocess execution authority が明示的に型・config・grant として扱われる。
-- Feature-provided long-running service / connection manager を Pod lifetime に安全に接続できる。
-- discovery 後の dynamic tool contribution が通常 ToolRegistry と permission path に統合される。
-- MCP spec baseline `2025-11-25` に基づく local stdio server integration がある。
-- MCP tools が namespaced stable Yoi tool として使える。
-- MCP resources/prompts が明示 tool operation として使え、取得結果は通常 tool result として history に残る。
-- server-provided data が system/developer instruction、scope、permission、prompt-context、history persistence rules を弱めない。
-- secrets / env values / command args containing secrets が diagnostics、logs、model context に plaintext で出ない。
-- Streamable HTTP、remote auth、distribution、sampling、elicitation の扱いが out-of-scope / fail-closed / follow-up として明示されている。
-- local mock MCP server による focused tests と、関連 crate tests、`nix build .#yoi` による packaging validation が定義されている。
 
-## Decision context
+- A local mock MCP server can be configured explicitly and initialized.
-
+- Discovered MCP tools appear as ordinary Yoi tools with stable namespacing.
-- `00001KST8H4M0` は broad MCP integration Ticket として作られていたが、今後はこの Objective の背景 context として扱い、実装 authority は concrete Tickets に置く。
+- Tool calls go through ordinary permission and history paths.
-- `00001KTR81P9X` は API/architecture prerequisite。MCP 実装が ToolRegistry / permission / history path を迂回しないための土台を作る。
+- MCP resources/prompts are explicit operations, not hidden context injections.
-- `00001KTR82RB7` は MCP implementation Ticket。API 拡張の結果に乗って local stdio MCP server features を実装する。
+- MCP result forms are bounded and safely serialized.
-- Objective-to-Ticket links は context であり、dependency/scheduling authority ではない。実際の routing / readiness / blockers は各 Ticket の body/thread/artifacts と Orchestrator 判断に置く。
+- Secret values, command/env details, and server diagnostics are redacted where required.
-- `resources/prompts` は scope 外に固定しない。安全条件は「direct hidden context injection をしない」ことであり、明示 tool result として扱うなら MCP integration の対象に含める。
+- Local server trust boundary is documented: Yoi does not sandbox the configured executable through feature authority.
+- Feature, Plugin, and MCP permission/trust responsibilities are documented as separate layers.

+Approve.
+
+Delta reviewed:
+- Re-reviewed the fix commit `b30b43b9 test: cfg-gate e2e observer payloads` after the earlier request-changes review.
+- Inspected the updated observer module boundary and call sites in `crates/tui/src/lib.rs` and `crates/tui/src/multi_pod.rs`, plus the unchanged harness/tests in `tests/e2e`.
+
+Evidence:
+- `e2e_observer` is now only compiled from `crates/tui/src/lib.rs` under `#[cfg(feature = "e2e-test")]`; the previous normal-build no-op facade was removed.
+- Observer payload construction is gated at call sites with `#[cfg(feature = "e2e-test")]`, including `panel_ready`, `selection_changed`, `action_requested`, `quit_requested`, and `emit_rows_rendered` calls.
+- Panel E2E DTOs/helpers (`PanelE2eRowKey`, `PanelE2eRect`, `PanelE2eRenderedRow`, `PanelE2eRowsRendered`, `App::emit_rows_rendered`) are now behind `#[cfg(feature = "e2e-test")]`, so the normal panel render path no longer builds row snapshots or retains that runtime helper path.
+- The background-task hold seam is still feature-gated: `check_background_task_hold` and `release_background_task_hold` calls are under `#[cfg(feature = "e2e-test")]`, and `YOI_TUI_TEST_HOLD_BACKGROUND_TASK` behavior lives in the gated observer module.
+- Mouse capture tracking remains intact in the harness: it tracks `?1000h` and `?1006h`, `click(...)` requires both capture modes before injecting PTY bytes, the test waits for rendered rows, asserts `selection_changed`, and asserts no `action_requested` dispatch.
+- Quit-latency coverage remains intact: the test waits for `panel_ready`, then verifies an actual pending `reload` background-task barrier before sending Ctrl+C through the PTY and asserting bounded exit.
+- The production/non-production boundary now satisfies the Ticket intent: the harness remains opt-in, observability is read-only and feature-gated, and no UI input/action path is bypassed.

+Request changes.
+
+Evidence reviewed:
+- Inspected Ticket record and `git diff 134e8b8b..HEAD` for commits `96561897` and `10a1c383`.
+- `tests/e2e` provides a credible first declarative harness (`PanelHarness::spawn`, `wait_for`, `wait_for_rows`, `click`, `press`, `expect_selection`, `expect_exit_within`, artifacts/metadata/input/output/event logs). This is not merely a fixed-sleep shell script.
+- Mouse-selection scenario waits for rendered rows, verifies both normal mouse and SGR mouse capture before `click`, sends the click through PTY bytes, waits for `selection_changed`, and asserts no `action_requested` dispatch.
+- Quit-latency scenario creates a real feature-gated background-task hold barrier, waits until the task is actually waiting before sending Ctrl+C through the PTY, and measures bounded exit latency.
+- `yoi-e2e` is opt-in via package feature/test `required-features = ["e2e"]`; e2e tests are outside default members. `YOI_TUI_TEST_EVENTS` and `YOI_TUI_TEST_HOLD_BACKGROUND_TASK` env behavior is behind `tui/e2e-test` / `yoi/e2e-test` feature gates, and the hook is observability-only.
+
+Required change:
+- The normal production build still contains/evaluates too much e2e harness glue. In non-`e2e-test` builds, `crates/tui/src/e2e_observer.rs` exposes no-op `emit`/hold functions, but call sites still execute test-specific data construction. In particular `App::emit_rows_rendered` and its panel row key/rect DTOs are compiled unconditionally and `app.emit_rows_rendered()` is called from the panel render path, causing row snapshots to be built every draw even though emission is a no-op. Selection/action/quit call sites also construct `serde_json::json!` payloads before the no-op facade. This violates the recorded boundary that production binaries should not contain harness logic and production-side hooks must be feature-gated/compiled out for normal builds.
+  - Please cfg-gate the call sites/helpers/DTOs, or use a lazy cfg-gated macro/helper so normal builds do not evaluate or retain e2e event payload construction. A tiny compile-only facade is acceptable only if it does not execute or allocate e2e-specific work and does not keep harness DTO logic in the normal runtime path.

+
+## Decision
+
+E2E scope refinement: TUI/Panel PTY 自動化もこの Ticket の範囲に含める。
+
+背景:
+- Panel mouse selection / Panel Quit latency の直近不具合では、focused unit test と code-path review だけで `done` 判定し、実端末経路の positive validation / measured validation が不足していた。
+- 既存本文の「TUI バイナリを PTY で叩く方針は採らない」は、blind な固定入力スクリプトや GUI 代替としての ad hoc 操作を避ける意図として扱い、TUI/Panel の実プロセス・実端末入力を検証する automated PTY harness は本 Ticket に含める。
+- Pod protocol/subprocess E2E と TUI/Panel PTY E2E は harness の部品は違うが、どちらも「実プロセスを spawn して user-visible boundary を検証する」ため、別 umbrella に分けず、この E2E harness Ticket の phase として扱う。
+
+方針:
+- 固定 sleep + 固定 input だけの PTY script は採用しない。Harness は UI からの structured feedback を待ってから入力を送る。
+- TUI/Panel には test-only / opt-in の observability route を追加する。これは UI action を bypass する command channel ではなく、状態観測・同期・失敗診断のための read-only probe とする。
+- 実際の keyboard / mouse / Ctrl+C 入力は PTY 経由で送る。Probe は `first_draw`、`panel_snapshot_ready`、`rows_rendered`、`selection_changed`、`actionbar_changed`、`background_task_started/finished/aborted`、`quit_requested`、`terminal_cleanup_started/finished`、`exit` などの structured event を JSONL 等で吐く。
+- Mouse E2E は `rows_rendered` の row key と screen rect を待ち、SGR mouse sequence を PTY に送って、`selection_changed` と screen/actionbar/detail の変化を確認する。
+- Quit latency E2E は `panel_ready` / background work pending などの barrier event を待ってから `Ctrl+C` / `Ctrl+D` を送り、`quit_requested -> exit` の elapsed を測る。非本質 background work が abort/drop され、terminal cleanup が行われることも event で確認する。
+- Screen output は `vt100`/`vte` 等の terminal parser で secondary oracle / artifact として保存する。主要同期は structured event に寄せる。
+- Test probe は `--tui-test-events <path>` 等の明示的な hidden/dev/test flag か `e2e` feature 配下の構成で有効化し、通常実行・model context・Ticket authority・Pod protocol には影響させない。
+- Failure artifact として event JSONL、input log、screen dump、stdout/stderr、runtime/data/workspace tmpdir の relevant tree、timing summary を保存する。
+
+受け入れ条件の追加案:
+- `cargo test -p e2e --features e2e`（または同等の opt-in command）で実 `yoi panel` を PTY 上で起動し、structured probe feedback を待ってから入力する harness が動く。
+- Panel row click E2E: rendered row rect を使って SGR mouse click を送り、selected row が変わることを assertion する。
+- Panel quit latency E2E: ready/pending background work barrier 後に Quit 入力を送り、exit latency が閾値内で、nonessential background work が quit を block しないことを assertion する。
+- Fixed sleep だけに依存する test は不可。ready/barrier event が来なければ screen dump と event log を artifact として失敗する。
+- Probe は read-only observability であり、input/action path を bypass しないことを reviewer が確認する。

+
+## Decision
+
+E2E design decision: Playwright-like declarative test API と production binary 非混入を前提にする。
+
+Decision:
+- E2E は ad hoc shell / fixed sleep script ではなく、Rust の独立 crate から宣言的に scenario を書ける構造にする。
+- 例: `PanelHarness::spawn(...)`、`panel.wait_for(PanelReady)`、`panel.click(row("ticket", id))`、`panel.expect_selection(...)`、`panel.press(CtrlC)`、`panel.expect_exit_within(...)` のように、Playwright 的な wait/action/assertion API を提供する。
+- Harness crate は production binary / normal library API から独立させる。想定配置は `tests/e2e/` または `crates/e2e_harness` + integration tests で、通常 build / release package / normal `yoi` binary に test harness logic を混ぜない。
+- 本番 binary に混ぜる必要があるものは、原則として「既存 TUI state から read-only diagnostic event を emit するための最小 test hook」に限定する。その hook も normal runtime では無効で、明示 feature / hidden dev flag / cfg(test/e2e) 等でしか有効化しない。
+- E2E harness は production code の内部関数を直接呼んで state mutation しない。入力は PTY、観測は structured test events / terminal screen parser、assertion は harness 側で行う。
+- Structured events は protocol authority ではなく test observability artifact として扱う。Ticket/Pod authority や user-visible semantics を変えない。
+
+Rationale:
+- 今回の Panel mouse / Quit latency の失敗は、unit/focused tests と code-path review だけでは user-visible terminal behavior を保証できないことを示した。
+- 一方で fixed sleep + input script は再現性・診断性が低く、ready 状態や background work barrier を確認できない。
+- Playwright-like API なら、test は「何を待ち、何を入力し、何を観測するか」を宣言的に表現でき、失敗時に event log / screen dump / timing artifact を残せる。
+- Production binary への混入を避けることで、release behavior / binary size / authority surface / model-visible surfaces を汚さない。
+
+Acceptance refinement:
+- E2E test author が fixed sleep ではなく `wait_for` / `expect` / `within` を使って Panel/TUI scenario を書ける。
+- Mouse selection と Quit latency の regression は、この declarative harness API 上の scenario として表現される。
+- Test-only observability route は opt-in であり、release/normal execution では無効または到達不能であることを reviewer が確認する。
+- Failure artifact に scenario step、last observed events、screen snapshot、timing、binary path、workspace/runtime dirs が含まれる。

+
+## Decision
+
+Routing decision: implementation_ready
+
+Reason:
+- ユーザーが E2E harness を 1 Ticket として扱い、Playwright-like declarative API、structured feedback、production binary 非混入を前提に進めることを明示した。
+- Ticket body は旧名/旧構成を含むが、thread decisions により現在の binding direction は明確化済み: Pod subprocess/protocol E2E と TUI/Panel PTY E2E を同じ harness Ticket の phase として扱う。
+- 直近の Panel mouse selection / Panel Quit latency の regression から、実プロセス・実 PTY・structured event feedback・failure artifact を最小スライスに含める必要がある。
+- `TicketRelationQuery` では durable blocker はなく、関連 Ticket は context link のみ。
+- Orchestrator worktree は clean。implementation side effect は state acceptance 後に dedicated child worktree で行う。
+
+Evidence checked:
+- Ticket body / thread decisions。
+- relation records: `00001KV072V89` / `00001KV0723PC` への related links。
+- orchestration plan records: なし。
+- current workspace state: Orchestrator worktree clean、queued/inprogress work なし、implementation child Pods なし。
+- project context: AGENTS guidance の E2E 未設計、prompt/resource boundary、production binary contamination 回避方針、直近 Panel validation failure records。
+
+IntentPacket:
+
+Intent:
+- Yoi の E2E testing foundation を、実プロセス spawn と TUI/Panel PTY automation の両方を扱える opt-in harness として導入する。
+- 最初の vertical slice は、Playwright-like declarative API、structured UI feedback、failure artifact、Panel mouse selection / Panel quit latency の regression scenario を実装できる形にする。
+
+Binding decisions / invariants:
+- E2E harness は independent crate / test surface とし、normal release / normal `yoi` binary に harness logic を混ぜない。
+- 本番 binary 側に必要な変更は opt-in read-only observability hook に限定する。UI action/state mutation を test hook で bypass しない。
+- 実入力は PTY 経由で送る。structured event は synchronization / assertion / artifact のための観測情報であり、authority channel ではない。
+- fixed sleep + fixed input だけの blind script を acceptance にしない。
+- Pod/Ticket authority、prompt/resource boundary、public runtime behavior を E2E 都合で歪めない。
+
+Requirements / acceptance criteria:
+- E2E author が Rust code で `spawn` / `wait_for` / `click` / `press` / `expect_*` / `within` を使って scenario を宣言的に書ける。
+- Opt-in command（例: `cargo test -p e2e --features e2e` または同等）で通常 CI 既定から分離される。
+- TUI/Panel test は panel ready / rows rendered / selection changed / background task / quit events など structured feedback を待ってから PTY input を送る。
+- Panel mouse selection regression と Panel quit latency regression の少なくとも skeleton または minimal passing scenario が declarative harness 上で表現される。
+- Failure artifact として event log、input log、screen dump、timing、binary path、workspace/runtime dirs が残る。
+- Production binary contamination がないこと、または opt-in hook が normal runtime で無効/到達不能であることを reviewer が確認できる。
+
+Implementation latitude:
+- `tests/e2e/` crate か `crates/e2e_harness` + integration tests のどちらに置くかは Coder が codebase constraints を見て選んでよい。ただし normal build/release contamination は避ける。
+- PTY crate、terminal parser、event JSONL format、fixture workspace builder の具体設計は Coder が選んでよい。
+- 最初の slice は full provider E2E ではなく、Panel/TUI harness と minimal process lifecycle / artifact foundation を優先してよい。
+- 既存旧名 `INSOMNIA_*` / `pod` references は現在の `yoi` / config surface に合わせて整理してよい。
+
+Escalate if:
+- read-only observability hook では足りず、production UI action path を test-only command channel で直接操作したくなる場合。
+- normal release binary / normal CLI surface に test-only options を露出させる必要がある場合。
+- workspace structure、Cargo package layout、Nix/package source filter に大きな変更が必要になる場合。
+- Provider stub / Pod protocol E2E まで同時に広げないと Panel slice が進められない場合。

+
+## Decision
+
+Design note: Panel mouse E2E は raw SGR sequence を固定送信するだけでは不十分。
+
+Rationale:
+- Harness が PTY に直接 `ESC [ < ... M` を書くと、実端末が mouse capture 有効時だけ mouse sequence を生成するという条件を bypass してしまい、今回のような「実端末ではイベントが来ない」系の不具合を見逃す可能性がある。
+- Mouse E2E は locator/row rect を使って coordinate を決めるだけでなく、TUI が mouse capture mode を有効化したことも検証する必要がある。
+
+追加すべき test harness 要件:
+- virtual terminal / screen parser は app output の terminal mode sequence（例: normal mouse + SGR mouse mode, `?1000h` / `?1006h` 相当）を tracking し、click helper は capture enabled が観測されていない場合に fail する。
+- もしくは explicit read-only structured event と terminal output assertion の両方で `mouse_capture_enabled` を確認する。
+- `click(row_selector)` は `rows_rendered` の rect から座標を選ぶが、raw SGR injection だけで成功扱いにしない。
+- assertion は `selection_changed` event、screen/actionbar/detail の secondary oracle、そして workflow action が発火していないことを組み合わせる。
+- これにより mouse selection E2E は面倒になるが、capture setup / coordinate mapping / event handling の user-visible path を分離して検証できる。

+
+<!-- event: decision author: orchestrator at: 2026-06-13T14:40:42Z -->
+
+## Decision
+
+Coder first-slice review: changes requested before external review.
+
+The initial E2E harness direction is promising, but it does not yet satisfy the regression-prevention bar from this Ticket.
+
+Required changes sent to Coder:
+1. Mouse E2E must not pass solely by injecting raw SGR mouse bytes. Harness must track terminal mouse capture enable output (`?1000h` / `?1006h` equivalent) and fail `click(...)` / expose `expect_mouse_capture_enabled()` when capture was not observed.
+2. Production binary contamination must be reduced. The TUI JSONL observer currently appears to be available in normal builds via `YOI_TUI_TEST_EVENTS`; prefer explicit `e2e-test` feature/cfg gating so release/normal binary has the hook compiled out. Report if feature gating is too large.
+3. Quit latency E2E must wait for a real pending/background-work barrier at the moment of quit, not merely assert that `background_task_started` happened sometime earlier. Strengthen the scenario to prove Ctrl+C while pending work exists exits promptly.
+4. Update implementation_report and validation evidence after changes.
+
+Reason:
+- The mouse selection regression specifically needs to catch missing terminal mouse capture, which raw SGR injection can bypass.
+- The user explicitly requested a structure where E2E harness logic does not mix into the production binary.
+- The quit latency regression needs measured user-visible behavior under a synchronized pending-work condition, not a loose startup smoke test.

+
+## Implementation report
+
+Implemented an opt-in E2E testing foundation for real `yoi panel` process automation.
+
+API / harness shape:
+- Added workspace package `tests/e2e` (`yoi-e2e`) with required feature `e2e`, so scenarios are opt-in.
+- Added `PanelHarness::spawn(...)`, `wait_for(...)`, `wait_for_rows(...)`, `click(...)`, `press(...)`, `expect_selection(...)`, `expect_exit_within(...)`, and `artifacts()`.
+- Harness drives the real `yoi panel` binary through a Unix PTY and sends SGR mouse / keyboard bytes through that PTY only.
+- Harness captures artifacts under a per-run artifact directory: `events.jsonl`, `input.log`, `pty-output.log`, and `run.json`.
+
+Production / non-production boundary:
+- Harness logic stays in `tests/e2e` and is not mixed into production crates.
+- Production-side change is limited to an opt-in read-only TUI JSONL observer enabled only by `YOI_TUI_TEST_EVENTS`.
+- Observer records Panel/TUI synchronization and assertion events (`panel_ready`, `rows_rendered`, `selection_changed`, `mouse_click`, `action_requested`, `quit_requested`, background task lifecycle, terminal cleanup, exit).
+- The observer does not mutate UI state, inject input, bypass actions, or grant authority; real input remains PTY-only.
+
+Scenarios added:
+- Panel mouse selection regression: waits for rendered rows, sends an SGR mouse click through PTY, asserts selection changed, and asserts no panel action was dispatched.
+- Panel quit latency regression: waits for Panel ready plus background-task barrier, sends Ctrl+C through PTY, asserts clean exit within the threshold, and verifies the quit event.
+
+Files changed:
+- `Cargo.toml`, `Cargo.lock`
+- `crates/tui/src/lib.rs`
+- `crates/tui/src/multi_pod.rs`
+- `crates/tui/src/e2e_observer.rs`
+- `tests/e2e/Cargo.toml`
+- `tests/e2e/src/lib.rs`
+- `tests/e2e/tests/panel.rs`
+
+Validation:
+- `cargo build -p yoi` — passed.
+- `YOI_E2E_BIN=/home/hare/Projects/yoi/.worktree/e2e-harness/target/debug/yoi cargo test -p yoi-e2e --features e2e --test panel -- --nocapture` — passed (2 tests).
+- `cargo fmt --check` — passed.
+- `cargo check -p tui --all-targets` — passed.
+- `cargo check -p yoi --all-targets` — passed.
+- `cargo check -p yoi-e2e --all-targets --features e2e` — passed.
+- `git diff --check` — passed.
+
+Remaining gaps / risks:
+- The first slice is Unix PTY-based; cross-platform PTY support is not implemented.
+- The screen artifact is currently raw PTY output rather than a parsed terminal snapshot.
+- Fixture setup blocks Companion/Orchestrator role auto-spawn by placing intentionally invalid isolated test pod metadata in the fixture data dir; this avoids leaking live background Pods but should be replaced by a cleaner fixture strategy if the Panel gains an explicit test fixture mode.

+
+## Implementation report
+
+Follow-up implementation update for review-required changes:
+
+Mouse E2E false-positive prevention:
+- `PanelHarness` now tracks the PTY output for terminal mouse mode enable/disable escape sequences.
+- It requires both normal mouse tracking (`ESC[?1000h`, with disable `ESC[?1000l`) and SGR mouse mode (`ESC[?1006h`, with disable `ESC[?1006l`) to have been observed as currently enabled.
+- Added `PanelHarness::expect_mouse_capture_enabled()` and the Panel mouse E2E calls it before clicking.
+- `PanelHarness::click(...)` also fails with `MouseCaptureNotEnabled` if mouse capture has not been observed, so raw SGR mouse injection alone cannot make the test pass.
+
+Production binary contamination reduction:
+- Added explicit feature gates:
+  - `tui/e2e-test`
+  - `yoi/e2e-test = ["tui/e2e-test"]`
+- The `YOI_TUI_TEST_EVENTS` JSONL event path and the background-task hold seam are compiled only under `tui/e2e-test`.
+- Normal builds still type-check a no-op facade so call sites stay simple, but env-var observability/hold behavior is compiled out unless the feature is enabled.
+- E2E binary build command is now: `cargo build -p yoi --features e2e-test`.
+
+Quit latency barrier strengthening:
+- Added a feature-gated test-only seam `YOI_TUI_TEST_HOLD_BACKGROUND_TASK=reload` that holds the Panel reload task pending in the E2E binary until quit aborts it.
+- Added `PanelHarness::expect_background_task_pending("reload")`, which verifies that a `background_task_started` event exists and no matching `background_task_finished` or `background_task_aborted` event has superseded it.
+- The quit latency test now uses the hold seam and asserts pending reload work immediately before sending Ctrl+C through the PTY.
+
+Harness/artifact adjustment:
+- E2E fixture artifacts now persist under workspace `target/e2e-artifacts/...` instead of package-local temporary dirs, so failure artifacts remain inspectable.
+
+Validation after update:
+- `cargo fmt --check` — passed.
+- `cargo build -p yoi --features e2e-test` — passed.
+- `YOI_E2E_BIN=/home/hare/Projects/yoi/.worktree/e2e-harness/target/debug/yoi cargo test -p yoi-e2e --features e2e --test panel -- --nocapture` — passed (2 tests).
+- `git diff --check` — passed.
+- `cargo check -p tui --all-targets` — passed.
+- `cargo check -p yoi --all-targets` — passed.
+- `cargo check -p tui --all-targets --features e2e-test` — passed.
+- `cargo check -p yoi --all-targets --features e2e-test` — passed.
+- `cargo check -p yoi-e2e --all-targets --features e2e` — passed.
+
+Remaining gaps / risks:
+- The E2E harness remains Unix PTY based.
+- The screen artifact remains raw PTY output, not a parsed terminal snapshot.
+- The test-only pending-task hold intentionally changes timing only for the `e2e-test` binary; it is not compiled into normal builds.

+
+## Review: request changes
+
+Request changes.
+
+Evidence reviewed:
+- Inspected Ticket record and `git diff 134e8b8b..HEAD` for commits `96561897` and `10a1c383`.
+- `tests/e2e` provides a credible first declarative harness (`PanelHarness::spawn`, `wait_for`, `wait_for_rows`, `click`, `press`, `expect_selection`, `expect_exit_within`, artifacts/metadata/input/output/event logs). This is not merely a fixed-sleep shell script.
+- Mouse-selection scenario waits for rendered rows, verifies both normal mouse and SGR mouse capture before `click`, sends the click through PTY bytes, waits for `selection_changed`, and asserts no `action_requested` dispatch.
+- Quit-latency scenario creates a real feature-gated background-task hold barrier, waits until the task is actually waiting before sending Ctrl+C through the PTY, and measures bounded exit latency.
+- `yoi-e2e` is opt-in via package feature/test `required-features = ["e2e"]`; e2e tests are outside default members. `YOI_TUI_TEST_EVENTS` and `YOI_TUI_TEST_HOLD_BACKGROUND_TASK` env behavior is behind `tui/e2e-test` / `yoi/e2e-test` feature gates, and the hook is observability-only.
+
+Required change:
+- The normal production build still contains/evaluates too much e2e harness glue. In non-`e2e-test` builds, `crates/tui/src/e2e_observer.rs` exposes no-op `emit`/hold functions, but call sites still execute test-specific data construction. In particular `App::emit_rows_rendered` and its panel row key/rect DTOs are compiled unconditionally and `app.emit_rows_rendered()` is called from the panel render path, causing row snapshots to be built every draw even though emission is a no-op. Selection/action/quit call sites also construct `serde_json::json!` payloads before the no-op facade. This violates the recorded boundary that production binaries should not contain harness logic and production-side hooks must be feature-gated/compiled out for normal builds.
+  - Please cfg-gate the call sites/helpers/DTOs, or use a lazy cfg-gated macro/helper so normal builds do not evaluate or retain e2e event payload construction. A tiny compile-only facade is acceptable only if it does not execute or allocate e2e-specific work and does not keep harness DTO logic in the normal runtime path.

+## Implementation report
+
+Follow-up implementation update for reviewer request `559adb9a ticket: request e2e harness changes`:
+
+Production/non-production boundary fix:
+- Removed the normal-build no-op `e2e_observer` module path and now compile the observer module only behind `tui/e2e-test` via `#[cfg(feature = "e2e-test")] mod e2e_observer;`.
+- Added `#[cfg(feature = "e2e-test")]` to all Panel/TUI observability call sites that build JSON payloads, including terminal cleanup/exit, panel ready, rows-rendered, mouse click, selection changes, action requests, quit request, and background task lifecycle events.
+- `App::emit_rows_rendered`, `PanelE2eRowKey`, `PanelE2eRect`, `PanelE2eRenderedRow`, `PanelE2eRowsRendered`, and the conversion helpers are now compiled only with `tui/e2e-test`.
+- Normal builds no longer call `app.emit_rows_rendered()`, no longer evaluate `serde_json::json!` e2e payloads, and no longer retain the Panel E2E DTO/helper logic in the runtime path.
+- The background reload hold seam remains compiled/called only under `tui/e2e-test`; `YOI_TUI_TEST_EVENTS` and `YOI_TUI_TEST_HOLD_BACKGROUND_TASK` behavior remains feature-gated.
+
+Preserved E2E behavior:
+- Mouse E2E still verifies PTY output for normal mouse tracking + SGR mouse enable sequences before any raw SGR click can be sent.
+- `PanelHarness::click(...)` still fails if mouse capture was not observed.
+- Quit latency E2E still uses the feature-gated pending reload hold barrier and asserts the reload task is pending before Ctrl+C.

+
+## Review: approve
+
+Approve.
+
+Delta reviewed:
+- Re-reviewed the fix commit `b30b43b9 test: cfg-gate e2e observer payloads` after the earlier request-changes review.
+- Inspected the updated observer module boundary and call sites in `crates/tui/src/lib.rs` and `crates/tui/src/multi_pod.rs`, plus the unchanged harness/tests in `tests/e2e`.
+
+Evidence:
+- `e2e_observer` is now only compiled from `crates/tui/src/lib.rs` under `#[cfg(feature = "e2e-test")]`; the previous normal-build no-op facade was removed.
+- Observer payload construction is gated at call sites with `#[cfg(feature = "e2e-test")]`, including `panel_ready`, `selection_changed`, `action_requested`, `quit_requested`, and `emit_rows_rendered` calls.
+- Panel E2E DTOs/helpers (`PanelE2eRowKey`, `PanelE2eRect`, `PanelE2eRenderedRow`, `PanelE2eRowsRendered`, `App::emit_rows_rendered`) are now behind `#[cfg(feature = "e2e-test")]`, so the normal panel render path no longer builds row snapshots or retains that runtime helper path.
+- The background-task hold seam is still feature-gated: `check_background_task_hold` and `release_background_task_hold` calls are under `#[cfg(feature = "e2e-test")]`, and `YOI_TUI_TEST_HOLD_BACKGROUND_TASK` behavior lives in the gated observer module.
+- Mouse capture tracking remains intact in the harness: it tracks `?1000h` and `?1006h`, `click(...)` requires both capture modes before injecting PTY bytes, the test waits for rendered rows, asserts `selection_changed`, and asserts no `action_requested` dispatch.
+- Quit-latency coverage remains intact: the test waits for `panel_ready`, then verifies an actual pending `reload` background-task barrier before sending Ctrl+C through the PTY and asserting bounded exit.
+- The production/non-production boundary now satisfies the Ticket intent: the harness remains opt-in, observability is read-only and feature-gated, and no UI input/action path is bypassed.

+
+## Comment
+
+Post-merge design gap: E2E harness の `yoi` binary freshness はまだ自動保証されていない。
+
+Current behavior:
+- `tests/e2e/src/lib.rs::yoi_binary()` は `YOI_E2E_BIN` があればその path を使う。
+- `YOI_E2E_BIN` が無い場合は E2E test binary の `current_exe()` から `target/{debug,release}/yoi` を推測し、最後に `target/debug/yoi` へ fallback する。
+- Harness は `PanelHarness::spawn` と fixture setup commands の両方でその binary path を使い、`YOI_POD_RUNTIME_COMMAND` も同じ binary に向ける。
+- しかし harness 自身は `cargo build -p yoi --features e2e-test` を実行しない。したがって任意タイミングの `cargo test -p yoi-e2e --features e2e` だけでは、最新 source から rebuild された binary が使われる保証はない。
+
+Gap:
+- 今回の validation は Orchestrator が事前に `cargo build -p yoi --features e2e-test` を実行したため正しい binary を使った。
+- ただし harness design としては freshness が runner/manual discipline に依存しており、stale `target/debug/yoi` や別 path の `YOI_E2E_BIN` を使っても test が走り得る。
+
+Follow-up direction:
+- `cargo xtask e2e` / `yoi-e2e-runner` / documented `just e2e` など、必ず `cargo build -p yoi --features e2e-test` を実行してから `YOI_E2E_BIN=<fresh target binary> cargo test -p yoi-e2e --features e2e ...` する single entrypoint が必要。
+- さらに harness は起動 binary が `e2e-test` feature 有効であることを handshake/event/version で検証し、可能なら source commit/build timestamp/path metadata を artifact に残して stale/mismatched binary を diagnostic にするべき。

+
+<!-- event: decision author: orchestrator at: 2026-06-13T15:43:37Z -->
+
+## Decision
+
+Follow-up design note: E2E の `yoi` binary freshness は `cargo run` 直起動より、harness 内 `cargo build` + built binary spawn を標準にする。
+
+Decision candidate:
+- `cargo test -p yoi-e2e --features e2e` の test setup から `cargo build -p yoi --features e2e-test --bin yoi` を実行することは可能で、opt-in E2E では許容する。
+- ただし PTY scenario の process-under-test を `cargo run ... -- panel` にするのは避ける。Cargo wrapper の build output、process tree、signal forwarding、exit timing が混ざり、Panel quit latency の測定対象が曖昧になるため。
+- Harness には `BinaryProvider::CargoBuild` のような起動経路を持たせ、test 開始時に current workspace source から `yoi` を build し、得られた `target/{profile}/yoi` path を PTY で直接 spawn する。
+- これにより「任意タイミングの E2E 実行で最新 source から作った binary を使う」ことを起動経路として保証しつつ、実際の UI/latency 測定は Cargo wrapper ではなく `yoi` binary 本体を対象にできる。
+- 複数 test の重複 build は `OnceLock`/suite setup 等で 1 回にまとめる。parallel test 実行時の cargo target lock 待ちは opt-in E2E では許容し、必要なら serial 化する。
+
+Rationale:
+- 起動後 handshake で正しさを検証するより、起動経路として build step を harness に内蔵する方が単純。
+- `cargo run` は可能だが、`run` は build + wrapper spawn を同時に行うため、PTY/Signal/timing の被測定経路に Cargo が入ってしまう。`cargo build` と direct binary spawn に分ける方が E2E の oracle が明確。

+
+## Decision
+
+Follow-up requested by user: E2E harness should build the current `yoi` binary itself instead of relying on a prebuilt `YOI_E2E_BIN` / inferred `target/debug/yoi`.
+
+Required correction:
+- Default E2E binary provider should run `cargo build -p yoi --features e2e-test --bin yoi` from the workspace root at test time, then spawn the resulting `target/{profile}/yoi` directly through PTY.
+- `YOI_E2E_BIN` may remain as an explicit override, but normal arbitrary `cargo test -p yoi-e2e --features e2e ...` should use a freshly built binary without requiring a separate manual build step.
+- Do not use `cargo run` as the process-under-test because that would put Cargo in the PTY/signal/quit-latency measurement path.
+- Preserve the existing production/non-production boundary and E2E feature gating.

+## Goal
+
+Design Yoi's Plugin model as a user-facing package/config/runtime layer built on top of `pod::feature` and a deliberately small host API.
+
+Use three stable terms:
+
+- **Plugin runtime**: how Plugin code/config is executed.
+- **Plugin surface**: what the Plugin adds to Yoi.
+- **Plugin host API**: what Yoi-provided capabilities a Plugin runtime may call while implementing a surface.
+
+`pod::feature` remains the internal substrate for contribution registration, lifecycle diagnostics, and Worker/ToolRegistry/HookRegistry integration. Plugin owns package identity, enablement, runtime selection, Plugin-layer permissions, trust policy, and host API grants.
+
+MCP is not the Plugin model and should not be treated as a Plugin permission backend. MCP is a separate protocol-backed integration layer that also uses `pod::feature` and owns MCP-specific enablement/trust policy.
+
 ## Background
 
-insomnia currently has internal Hook / Tool concepts, plus a separate planned MCP integration ticket (`mcp-integration`). The next design step is to define the project-level Plugin surface: how user/project-provided extensions can contribute Tools and Hooks without weakening scope, permission, history, or prompt-context invariants.
+Yoi already has internal extension-like surfaces:
 
-The plugin surface should not be a grab bag of arbitrary code execution. Candidate extension mechanisms have different trust and protocol properties:
+- Tools via `llm_worker::ToolRegistry` / `ToolDefinition`
+- Hooks via `HookRegistry` / `HookEvent` / `HookAction`
+- Feature contribution declarations in `pod::feature`
+- Built-in features such as task and ticket tools
 
-- MCP: protocol-bound external tool/resource/prompt provider surface.
+Plugin design must not let external packages bypass Worker history, prompt/context invariants, scoped tool permissions, restore snapshot authority, or launch-policy authority.
-- TOML/config-only hooks: declarative configuration for simple hook behavior without arbitrary code.
-- WASM: planned first programmable plugin runtime for Hooks and Tools, with explicit capability imports and sandboxing.
-- General scripting languages: considered, but not the initial direction because arbitrary script execution broadens the trust/runtime surface too quickly.
 
-## Related work
+Prior Hook hardening work constrains model-visible context mutation so Plugin exposure can stay safe. Plugin design should reuse those safe surfaces rather than creating parallel prompt/history/tool paths.
 
-- `work-items/open/20260529-161928-mcp-integration/` — MCP integration as one plugin backend / external capability bridge.
+A concrete future use case is a chat bridge such as Slack/Discord. The preferred architecture is not that Yoi starts or bundles a full Slack/Discord SDK process. An externally managed bridge service, such as a `discord.js` service, may expose a small HTTPS API; a Yoi Plugin can call that API using configured URL/auth data. A Plugin may also run a Pod-lifetime service loop and submit external events through a host-mediated Ingress surface, but those semantics must stay concrete and bounded.
-- `work-items/open/20260603-122317-plugin-feature-contribution-registry/` — implementation-oriented runtime registry split-out for built-in and external feature contributions.
+
-- `work-items/open/20260603-122317-hook-public-surface-hardening/` — prerequisite hardening for public Hook contribution safety.
+## Plugin runtime
-- Existing internal hooks/tools code: `crates/pod`, `crates/tools`, `crates/llm-worker`.
+
-- Manifest permission policy and scope enforcement must remain authoritative for plugin-provided tools.
+Runtime answers: **how is Plugin code/config executed?**
+
+Supported design vocabulary:
+
+- `declarative`: config-only Plugin behavior, no arbitrary code execution.
+- `wasm`: sandboxed WASM Plugin module with explicit host APIs.
+- `external_process`: future/optional runtime. Do not assume it for the initial Plugin model.
+
+The initial runtime direction is:
+
+```text
+runtime: declarative and/or wasm
+host APIs: https + fs, plus surface-intrinsic ingress/diagnostics where required
+surfaces: Tool + Hook + Service + Ingress
+```
+
+## Plugin surface
+
+Surface answers: **what does the Plugin add to Yoi?**
+
+The Plugin surfaces are:
+
+- `Tool`
+- `Hook`
+- `Service`
+- `Ingress`
+
+Do not use `Outbound` as a separate surface. External writes are represented as Tool surface entries with side-effect metadata.
+
+### Tool surface
+
+A Tool surface adds model/workflow-callable operations through ordinary Yoi ToolRegistry paths.
+
+External side effects such as chat sends are Tools:
+
+```text
+discord_send_message
+slack_reply_thread
+github_create_issue_comment
+```
+
+Requirements:
+
+- registers through ordinary ToolRegistry / `pod::feature` paths
+- uses normal model-visible schema exposure
+- passes normal PreToolCall permission policy
+- commits tool call/result through normal history plumbing
+- uses bounded result serialization
+- declares side-effect metadata such as `effect = "external_write"` where applicable
+- validates configured destination allowlists before executing external writes
+
+### Hook surface
+
+A Hook surface reacts to supported Yoi lifecycle events using the hardened public Hook API.
+
+Requirements:
+
+- no raw hidden `Item` injection
+- no prompt/context mutation outside durable history-aware paths
+- explicit supported `HookAction` subset only
+- Hook-triggered external writes must still go through Tool or another explicit host-approved path, not hidden side effects
+
+### Service surface
+
+A Service surface is Pod-lifetime Plugin work managed by Yoi's Plugin runtime.
+
+The initial Service contract is concrete and limited:
+
+- Services start during Pod startup after explicit Plugin enablement is resolved.
+- Services stop when the Pod stops or when the Plugin instance is replaced during restore/relaunch.
+- Services report lifecycle state: `starting`, `ready`, `degraded`, `failed`, `stopping`, `stopped`.
+- Services may use only granted Plugin host APIs, initially `https` and `fs`, plus surface-intrinsic diagnostics and ingress submission where granted.
+- Services must be cancellable and must not block Pod shutdown indefinitely.
+- Service diagnostics must be bounded and must redact secrets.
+
+For chat bridge Plugins, Service is the WASM-side client loop that communicates with an externally managed bridge service over HTTPS polling or other explicitly designed future event mechanisms. WebSocket/SSE are not implied by the word Service; they require separate host API design.
+
+### Ingress surface
+
+Ingress is the host-mediated surface for external events entering Yoi.
+
+Plugins do **not** directly choose `Notify`, `Run`, target Pod, or hidden context insertion. A Plugin submits a typed external event to the host:
+
+```text
+host.ingress.submit(event)
+```
+
+Then host routing policy decides delivery:
+
+```text
+submit external event -> route/dedup/bounds/policy -> notify | run | drop | diagnostic
+```
+
+Initial typed event target for chat bridges:
+
+```text
+ExternalMessageEvent {
+  source_plugin,
+  provider,
+  external_workspace_id/team_id/guild_id,
+  channel_id,
+  thread_id?,
+  message_id,
+  actor_id,
+  actor_display_name?,
+  text,
+  attachments[],
+  timestamp,
+  permalink?,
+  dedup_key,
+}
+```
+
+Requirements:
+
+- external content is untrusted
+- event size is bounded before entering Yoi history/model-visible context
+- host performs deduplication and loop prevention
+- host routing config decides target Pod and delivery mode
+- accepted events are appended through durable history/notification paths before they can affect model context
+- rejected/dropped events produce bounded diagnostics without unnecessarily storing message content
+
+## Plugin host APIs
+
+Host API answers: **what Yoi-provided capabilities can a Plugin runtime call while implementing a surface?**
+
+Host APIs are runtime capabilities controlled by Plugin-layer grants. Keep this set narrow. Do not add a broad API to avoid deciding concrete semantics.
+
+The initial general-purpose host API set is:
+
+- `https`: bounded HTTPS client only.
+- `fs`: scoped filesystem read/write under explicit Plugin grants.
+
+Surface-intrinsic host calls also exist where required:
+
+- `ingress.submit`: available only to Plugins granted the Ingress surface.
+- `diagnostics`: bounded lifecycle/error/health reporting for Plugin runtime and Service surface.
+
+Use `https`, not `web`, for the initial network API. The first network host API should not imply arbitrary browser-like web capabilities, raw TCP, local network access, HTTP without TLS, WebSocket, SSE, DNS policy, or remote fetching semantics beyond the explicitly designed HTTPS client.
+
+### `https` host API
+
+Initial requirements:
+
+- HTTPS only
+- explicit allowlist of origins or exact endpoints
+- bounded request/response size
+- timeout/cancellation
+- configured headers/auth data only through Plugin enablement policy
+- no implicit access to ambient environment variables or host credentials
+- diagnostics must redact credentials and sensitive headers
+
+WebSocket, SSE, long polling helpers, and inbound server/webhook APIs are out of the initial host API unless a later Ticket designs them explicitly.
+
+### `fs` host API
+
+Initial requirements:
+
+- scoped paths explicitly granted by Plugin-layer policy
+- no automatic inheritance from Pod workspace scope
+- bounded read/write operations
+- path traversal protection
+- diagnostics that identify denied paths without leaking file contents
 
 ## Requirements
 
-- Define a Plugin surface that can provide:
+- Define Plugin as a user-facing layer over `pod::feature`, not as the feature API itself.
-  - Tools callable by the LLM through the normal ToolRegistry / permission / scope path;
+  - Plugin package/config/runtime code eventually contributes through `pod::feature`.
-  - Hooks observing or influencing Pod/Worker lifecycle through the existing Hook boundary, not by directly mutating worker history/context.
+  - `pod::feature` remains responsible for contribution declarations, lifecycle, diagnostics, and registration plumbing.
-- Separate plugin description/registration from plugin runtime implementation.
+  - Plugin remains responsible for package enablement, provenance, runtime selection, host API grants, and Plugin-layer permission/trust policy.
-  - A plugin manifest should declare provided tools/hooks, required capabilities, configuration schema or config values, and trust/runtime type.
+- Use the terms `Plugin runtime`, `Plugin surface`, and `Plugin host API`; avoid durable/user-facing use of `contribution category`.
-  - Runtime implementations can include MCP, declarative config hooks, and WASM in separate phases.
+- Plugin surfaces are Tool / Hook / Service / Ingress.
-- Keep MCP as a related backend, not the whole plugin model.
+- Service has a Pod-lifetime lifecycle contract; it does not imply WebSocket/SSE/raw network support.
-  - MCP servers remain untrusted external capability providers bridged through allowlists, bounded output, scope/permission policy, and explicit resource/prompt use.
+- Ingress is `host.ingress.submit(typed external event)`; host routing decides notify/run/drop/diagnostic.
-- Define a declarative hook path for simple TOML/config-only behavior where code execution is unnecessary.
+- External outbound side effects are Tool surface entries with external-write metadata, not a separate Outbound surface.
-- Define a WASM plugin direction for programmable Hooks/Tools.
+- Initial general-purpose Plugin host APIs are only `https` and `fs`.
-  - WASM modules must receive explicit host imports/capabilities only.
+- `ingress.submit` and `diagnostics` are surface-intrinsic host calls, not broad ambient capabilities.
-  - File/network/process access must not be ambient; all external effects go through host-provided capability APIs and existing policy checks.
+- Do not expose a generic `web` API in the initial Plugin model.
-  - Tool outputs must be bounded and recorded through normal history/tool-result paths.
+- Define Plugin-layer permission and trust model separately from `pod::feature`.
-- Preserve LLM context/history invariants.
+  - Do not rely on feature-level `HostAuthority` / authority grants for Plugin permissions.
-  - Plugins must not inject cross-turn invisible context.
+  - Plugin grants are tied to package identity/runtime/user or workspace config, not feature install reports.
-  - If plugin output becomes model-visible, it must enter through durable history/tool/hook paths according to existing rules.
+  - Plugin policy decides which surfaces and host APIs a Plugin runtime can use.
-- Preserve scope and permission invariants.
+- Define runtime families separately.
-  - Plugin-provided tools must not bypass `ScopedFs`, manifest tool permission policy, child scope delegation, or web/network policy.
+  - Declarative/config-only Plugins
-- Clarify trust model and lifecycle.
+  - WASM Plugins
-  - Builtin vs project vs user plugins.
+  - External process Plugins only as an explicit future/optional runtime
-  - Discovery/enablement through manifest/profile/config.
+  - MCP remains a separate feature-backed protocol integration, not the Plugin permission model.
-  - Versioning / compatibility boundaries.
+- Plugin metadata, config, external data, and package content are untrusted input.
-  - Diagnostics when a plugin cannot load or asks for unavailable capabilities.
+- Plugin enablement must be explicit.
-
+  - package presence/discovery alone cannot enable or execute Plugin code
-## Non-goals
+  - workspace/user config must opt in to package/runtime/surface activation and host API grants
-
+- The design must document the boundary among Plugin, MCP, and built-in Features.
-- Implementing the full WASM runtime in the first design step.
-- Implementing MCP itself beyond referencing the existing MCP integration ticket.
-- Supporting arbitrary host scripting languages as a first-class plugin runtime.
-- Allowing plugins to mutate session history, memory, prompt context, or scope outside approved APIs.
-- Adding UI plugin systems or TUI rendering extensions.
-
-## Suggested phases
-
-1. **Design / architecture note**
-   - Define Plugin, PluginManifest, PluginRuntimeKind, Tool contribution, Hook contribution, capability request, and trust/source model.
-   - Map MCP, declarative hooks, and WASM onto that model.
-2. **Internal registry boundary**
-   - Detailed implementation is split to `plugin-feature-contribution-registry` so this ticket can stay focused on the architecture surface and invariants.
-3. **Declarative hooks MVP**
-   - Add a non-code configuration path for simple hook behavior if an immediate use case exists.
-4. **WASM spike**
-   - Evaluate runtime (`wasmtime` or alternative), host imports, resource limits, serialization, and Nix/package impact.
-5. **MCP bridge alignment**
-   - Ensure `mcp-integration` plugs into the same Tool/permission/output boundary rather than becoming a parallel extension path.
 
 ## Acceptance criteria
 
-- The repository has a documented plugin architecture proposal covering Tools, Hooks, runtimes, capability model, trust model, and discovery/enablement.
+- A design note or Ticket plan defines Plugin as a user-facing layer over `pod::feature`.
-- MCP is positioned as one plugin backend / bridge and linked to `mcp-integration`, not treated as the only extension mechanism.
+- The plan uses `runtime`, `surface`, and `host API` terminology and avoids relying on `contribution category` as the durable term.
-- The proposal explicitly explains why arbitrary scripting languages are deferred and why WASM is the initial programmable runtime direction.
+- The plan states that Plugin surfaces are Tool / Hook / Service / Ingress.
-- The design preserves existing scope, permission, history, and prompt-context invariants.
+- The plan states that Service has concrete Pod-lifetime lifecycle semantics and does not imply unspecified network/event APIs.
-- Follow-up implementation tickets can be cut independently for declarative hooks, WASM runtime, and MCP bridge integration.
+- The plan states that Ingress is typed external-event submission to the host, not direct Notify/Run/context injection.
-- Any code changes in this ticket, if taken beyond design docs, are limited to safe internal boundaries and have focused tests.
+- The plan states that external outbound side effects are Tool surface entries with external-write metadata.
+- The plan states that initial general-purpose Plugin host APIs are `https` and `fs` only.
+- The plan states that `https` is HTTPS-only and does not imply generic `web`/browser/raw-network capabilities.
+- The plan states that filesystem access is a Plugin host API controlled by Plugin-layer grants and does not inherit Pod workspace scope automatically.
+- The plan states that Plugin permissions are Plugin-layer policy and are not implemented by `pod::feature` `HostAuthority` grants.
+- The plan states that MCP is a separate feature-backed integration with MCP-specific enablement/trust policy.
+- The public Hook safety invariants from `00001KT6Q08R8` remain intact.
+- Tool Plugins are required to use ordinary ToolRegistry / permission / history / bounded-result paths.
+- No design path allows Plugin package presence alone to execute code or mutate context.
+- The design identifies which follow-up Tickets own package format, runtime implementation, host APIs, and Plugin permission details.
+
+## Suggested decomposition
+
+1. Public Hook surface hardening. Completed by `00001KT6Q08R8`.
+2. Feature contribution API substrate. Completed by `00001KT6Q08R9` and `00001KTR81P9X`.
+3. Plugin package/discovery format. Tracked by `00001KT0Z4BK8`.
+4. Plugin enablement plan + metadata snapshot restore integration.
+5. WASM/declarative runtime slice with Tool and Hook surfaces.
+6. Plugin host API slice for `https` and `fs` only.
+7. Service lifecycle surface.
+8. Ingress external-message submission and routing policy.
+9. Tool external-write metadata and destination allowlist enforcement.
+10. Future Ticket: streaming event APIs such as SSE/WebSocket/long polling, if HTTPS polling is insufficient.
+11. MCP local stdio integration remains tracked separately by `00001KTR82RB7`.
+
+## Notes
+
+- This Ticket is a design coordination Ticket; implementation should be split into concrete Tickets rather than landing a broad Plugin platform in one change.
+- Keep Plugin permission terms distinct from removed feature-layer `HostAuthority` terminology.
+- Avoid requiring Yoi to manage arbitrary external SDK processes for chat bridge support.
+- Avoid broad host APIs. Add host APIs only when a concrete Plugin surface and use case require them.

 ## Background
 
-The plugin extension surface ticket (`plugin-extension-surface`) defines Plugins as a safe contribution model for Tools and Hooks, with MCP, declarative hooks, and WASM treated as runtime mechanisms. The next design question is how plugins are distributed, discovered, installed, and enabled across user and workspace scopes.
+The plugin extension surface ticket (`00001KSXRQ4G8`) defines Plugins as the user-facing package/config/runtime layer that uses the `pod::feature` API substrate to contribute Tools, Hooks, and related runtime surfaces. The next design question is how plugins are distributed, discovered, installed, and enabled across user and workspace scopes.
+
+MCP is intentionally not modeled as a Plugin package/runtime in this Ticket. MCP is a separate feature-backed protocol integration with its own enablement and trust policy. Plugin package design may later reference MCP-related assets only through an explicitly approved follow-up; package discovery must not imply MCP server execution.
 
 The desired initial direction is a single-file plugin package that can be placed in user or workspace plugin stores, for example:
 
-- `~/.config/insomnia/plugins/<id>.insomnia-plugin`
+- `${XDG_DATA_HOME:-~/.local/share}/yoi/plugins/<id>.yoi-plugin`
-- `./.insomnia/plugins/<id>.insomnia-plugin`
+- `<workspace>/.yoi/plugins/<id>.yoi-plugin`
 
-The package should be easy to copy, inspect, cache, and pin, while preserving Insomnia's scope, permission, history, prompt-context, and trust invariants. In particular, workspace plugins may come from a repository checkout and must not execute merely because an archive exists under `./.insomnia/plugins`.

 ## Acceptance criteria
 
 - The repository has a documented plugin distribution/package proposal covering user and workspace plugin stores, single-file archive format, manifest fields, archive safety, cache/digest behavior, and discovery vs enablement.
-- The proposal explicitly states that placing a package in `~/.config/insomnia/plugins/` or `./.insomnia/plugins/` is discovery only, not execution or registration.
+- The proposal explicitly states that placing a package in `${XDG_DATA_HOME:-~/.local/share}/yoi/plugins/` or `<workspace>/.yoi/plugins/` is discovery only, not execution or registration.
 - The design maps package sources to user/project/builtin trust categories and defines how ID collisions and ambiguous selectors are handled.
-- The design explains how capability requests differ from host-granted capabilities and how existing scope/permission/secret/web policy remains authoritative.
+- The design explains Plugin permission requests/grants as Plugin-layer policy, distinct from `pod::feature` authority/grant concepts.
-- Runtime-specific notes cover declarative hooks, WASM packages, and MCP backend/bridge packaging constraints.
+- Runtime-specific notes cover declarative hooks and WASM packages; MCP is called out as a separate feature-backed integration, not part of initial Plugin packaging.
-- Follow-up implementation tickets can be cut independently for manifest/profile enablement, package discovery, archive validation/cache, WASM packaging, and MCP packaging alignment.

+## Decision
+
+決定:
+- `pod::feature` は API / contribution substrate として扱い、Plugin や MCP の権限管理を担わせない。
+- Plugin は `pod::feature` をユーザー向け package/config/runtime 形式で使わせる層であり、Plugin permission / trust policy は Plugin layer で定義する。
+- MCP は `pod::feature` 上に protocol-backed integration layer を構築するが、MCP server enablement / command-env-secret policy / trust boundary / MCP-specific permission は MCP layer が独自に持つ。
+- MCP local stdio server の OS-level side effects は Yoi feature authority では制御できないため、feature-layer authority / grant を MCP や Plugin の permission model に流用しない。
+
+反映:
+- `00001KTR81P9X` は authority ではなく provider lifecycle / dynamic contribution / normal ToolRegistry path / untrusted normalization に絞る。
+- `00001KTR82RB7` は MCP 固有の explicit config と trust model を持つ。
+- `00001KSXRQ4G8` と `00001KT0Z4BK8` は Plugin permission を Plugin layer として扱い、MCP を初期 Plugin packaging/runtime から分離する。

+
+決定:
+- Plugin discovery stores, source-qualified identity, discovery/enablement separation, Pod-startup initialization timing, restore behavior, and MCP boundaryをこの `00001KT0Z4BK8` の安定 contract として統合した。
+- User Plugin package store は `${XDG_DATA_HOME:-~/.local/share}/yoi/plugins/` とし、`~/.config/yoi/plugins/` は使わない。
+- Package presence は discovery only であり、実行・登録・runtime initialization は explicit enablement 後の Pod startup に限定する。
+- Restore は metadata snapshot の enabled Plugin plan を正本とし、fresh discovery で silent upgrade しない。

+## Comment
+
+Intake 確認:
+- Ticket `00001KT0Z4BK8` の body / thread / artifacts を確認した。この Ticket の現在の主題は Plugin distribution package format / discovery / enablement boundary であり、直近の user refinement「前何回かに渡って実装されたlatencyとかE2Eとかの話なんだけど」は、この Ticket の plugin package 要件とは直接対応しない。
+- 関連しそうな既存 Ticket として `00001KV0723PC`（Panel Quit latency）、`00001KSKBP9YG`（E2E harness）、`00001KV0TJVN5`（E2E binary/env isolation）、`00001KV0YK5S0`（E2E tmp/runtime isolation）、`00001KV10SN02`（E2E critical-path coverage）を確認した。いずれも closed で、latency/E2E の実装・検証・残差整理はそちらの系譜に記録されている。
+- 現時点では、Plugin package Ticket の readiness / requirements を変更する根拠は不足している。ユーザーに、(a) `00001KT0Z4BK8` に latency/E2E 由来の検証要件を追加したいのか、(b) latency/E2E 系の既存 Ticket に追記したいのか、(c) 新しい concrete follow-up Ticket が必要なのか、を確認する。
+

+- このコメントは要件同期の保留記録であり、queue / implementation routing ではない。
+- duplicate Ticket は作成していない。

+## Comment
+
+ユーザー確認の要点:
+- ユーザーは latency / mouse / E2E の経緯説明ではなく、最終的な evidence status を確認している。
+- Ticket 記録上、`00001KV0723PC` の元の Panel Quit latency 修正は post-merge measurement で「still present / not proven fixed」と記録されており、ユーザー観測の latency 改善としては最終的に認められていない。
+- `00001KV072V89` の元の mouse selection 修正も post-merge user verification で「マウス選択全く効かない」と記録され、元の done decision は insufficient とされている。
+- 後続 E2E は fixture/PTY 上で mouse click/wheel と quit pending-barrier regression を pass させたが、これは user の実環境・実インストール経路で latency が解消したこと、または mouse 操作が実際に動作したことの human/live confirmation ではない。
+- `00001KT0Z4BK8` 自体の Plugin package requirements には現時点で反映しない。必要なら別 follow-up Ticket として「E2E 結果と user-visible validation gap の整理 / merge gate 明文化」を扱う。

+## Decision
+
+Routing decision: implementation_ready_but_waiting_capacity
+
+Reason:
+- Ticket body / thread / artifacts、relation、OrchestrationPlan、Orchestrator workspace state を確認した。Plugin package / discovery / enablement boundary の design work item として要件・受け入れ条件・non-goals・invariants は十分に具体化されている。
+- blocking relation / OrchestrationPlan blocker はない。
+- Plugin package work は現在 active な Panel/TUI implementation と source surface が大きく重ならないため、設計上の conflict blocker ではない。
+- ただし現在 `00001KTFY8V80` と `00001KV09WYC6` の2件が inprogress で Coder Pod running。Reviewer follow-up と integration capacity も未使用ではなく、さらに queued Panel/TUI work 2件を待機させている。
+- 現時点では追加 Coder Pod を spawn せず、active Coder のいずれかが implementation report を返して review/integration 見通しが立ってから acceptance する。
+
+Evidence checked:
+- Ticket body/thread: Plugin package design requirements、過去の Plugin/MCP/feature-layer decision、`planning -> ready`、Panel `ready -> queued` を確認。
+- Ticket relations: blocker なし。
+- OrchestrationPlan: 既存 record なし。
+- Orchestrator workspace: `/home/hare/Projects/yoi/.worktree/orchestration` は clean、queue commit `4be6c966` 上。
+- Visible Pods: `yoi-coder-00001KTFY8V80` と `yoi-coder-00001KV09WYC6` が running。
+
+Next action:
+- 先行 inprogress Ticket の少なくとも1件が implementation report / review stage に進み、Coder capacity が空いた時点で再確認し、unblocked なら `queued -> inprogress` acceptance と dedicated worktree 作成へ進む。
+- planning return ではなく queued のまま waiting とする。

+
+## Decision
+
+Routing decision: implementation_ready
+
+Reason:
+- 先行 Coder のうち `00001KV09WYC6` が implementation report を返し review stage に入ったため、Plugin work 用の Coder capacity を再評価した。
+- Ticket body / thread / relations / orchestration plan / Orchestrator workspace state を再確認した。blocking relation はなく、既存 waiting note は capacity 起因であり、現在は1件分の Coder capacity を空けられる。
+- 本 Ticket は Plugin package / discovery / enablement boundary の design/documentation work が主で、active Panel/TUI implementation と source surface が大きく重ならない。
+- Plugin/MCP/feature-layer authority boundary に関する prior decisions は Ticket thread に記録済みで、残る不確実性は proposal の構成・記述・必要最小限の config shape 調査に閉じている。
+
+Evidence checked:
+- Ticket body / thread: package format、store/source mapping、discovery vs enablement、manifest semantics、runtime-specific notes、cache/pinning、diagnostics、prior Plugin/MCP/feature-layer decisions を確認。
+- Ticket relations: blocker なし。
+- OrchestrationPlan: capacity waiting note 1件のみ。blocking/conflict record なし。
+- Orchestrator workspace: `/home/hare/Projects/yoi/.worktree/orchestration` は clean、`80a9e40d` 上。
+- Active Pods: `00001KTFY8V80` coder running、`00001KV09WYC6` reviewer running。
+- Bounded code/doc map: Plugin docs は未作成。関連 candidate は `docs/design/*`, `crates/manifest/src/{config,profile}.rs`, `crates/pod/src/feature.rs`, `crates/pod/src/hook.rs`。
+
+IntentPacket:
+
+Intent:
+- `.yoi-plugin` package distribution/discovery/enablement boundary の durable design proposal を repository に追加し、後続 implementation Ticket を独立して切れる状態にする。
+
+Binding decisions / invariants:
+- Package presence in user/workspace plugin stores is discovery only; registration, WASM init, Hooks/Tools contribution, process/server startup, and MCP server launch require explicit enablement and grants.
+- Source-qualified identity is required: `user:<id>`, `project:<id>`, `builtin:<id>` are distinct; ambiguous unqualified IDs fail closed.
+- Plugin permission declarations are requests, not grants. Effective grants are Plugin-layer policy plus existing manifest/profile/scope/tool/web/secret/runtime allowlists.
+- Do not model Plugin permissions with `pod::feature` HostAuthority/grant concepts.
+- MCP remains a separate feature-backed integration and is out of initial Plugin packaging/runtime unless future Ticket explicitly approves a bridge.
+- Archive handling must reject path traversal and unsafe layout, use bounded extraction, compute deterministic digest, and materialize into digest-keyed cache before runtime initialization.
+- Restore should use resolved manifest/session metadata for enabled Plugin plan; fresh discovery must not silently upgrade a restored Pod.
+
+Requirements / acceptance criteria:
+- Repository contains a documented Plugin distribution/package proposal covering `.yoi-plugin` archive structure, root `plugin.toml`, assets, user/workspace/builtin stores, source/trust mapping, identity collision rules, discovery vs enablement, manifest fields, archive safety, cache/digest/pinning, diagnostics, and runtime-specific notes for declarative hooks and WASM.
+- Proposal explicitly states store placement is discovery only, not execution or registration.
+- Proposal distinguishes Plugin permission request/grant model from `pod::feature` authority concepts.
+- Proposal calls out MCP as separate and out of initial Plugin packaging.
+- Follow-up implementation cuts are clear for manifest/profile enablement, package discovery, archive validation/cache, Plugin permission policy, WASM packaging, and any future MCP/plugin bridge.
+
+Implementation latitude:
+- Primary deliverable may be a design doc plus minimal cross-references; code changes are optional and should stay within safe internal boundaries.
+- Coder may choose exact doc path/name consistent with existing docs organization.
+- If proposing config shape, prefer illustrative schemas over broad runtime implementation unless obviously small and safe.
+
+Escalate if:
+- A real runtime implementation becomes necessary to satisfy the Ticket.
+- Plugin package design would require changing Profile/manifest authority semantics, Pod restore semantics, secret handling, or MCP enablement model.
+- The proposal would imply workspace package execution or silent restore upgrades.
+
+Validation:
+- `cargo fmt --check` if code or Rust doc tests are touched.
+- `git diff --check` always.
+- If only Markdown docs are touched, focused validation may be `git diff --check` plus link/path sanity review.
+
+Current code/doc map:
+- Likely doc destination: `docs/design/`.
+- Related architecture candidates: `crates/manifest/src/config.rs`, `crates/manifest/src/profile.rs`, `crates/pod/src/feature.rs`, `crates/pod/src/hook.rs`.
+
+Critical risks / reviewer focus:
+- Discovery vs enablement separation.
+- Plugin permission requests vs grants.
+- MCP separation.
+- Source identity collision/fail-closed behavior.
+- Archive safety and digest/cache semantics.
+- Restore/fresh discovery no silent upgrade invariant。

+- MCP is explicitly out of initial Plugin packaging/runtime and requires a future separate bridge Ticket.
+- Follow-up implementation cuts are listed for enablement schema, discovery, validation/cache, permission policy, declarative hooks, WASM, locks, and future MCP bridge.
+
+Validation reported by coder:
+- Passed: `git diff --check`.
+- Link/path sanity review:
+  - Verified `docs/README.md` references existing `docs/design/plugin-packages.md`.
+  - Verified touched Markdown files have trailing newlines and no tab characters.
+- Post-commit check:
+  - `git status --short --branch` showed clean branch `impl/00001KT0Z4BK8-plugin-package-discovery`.
+  - `git diff --check HEAD~1 HEAD` passed with no whitespace errors.
+- No Rust/code changes were made, so `cargo fmt` / `cargo test` were not run.
+
+Repository status:
+- Child implementation worktree clean after commit.
+
+Residual risks / blockers:
+- This is intentionally a design proposal only. Exact manifest/Profile schema, lock-file format, archive limits, cache path, and WASM ABI details remain for follow-up implementation Tickets.

+- Passed: `git diff --check HEAD~1 HEAD`
+- README-listed relative doc target existence checked with shell commands.
+- Manual Markdown/design boundary review completed.

+- No cargo commands because the change is documentation-only.
+- A Python-based link check could not run because `python3` is unavailable; shell existence checks were used instead.

+## Comment
+
+## Intake refinement
+
+既存 Ticket `00001KTFY8V80` を確認した。新規 duplicate Ticket は作成しない。
+
+### Readiness
+
+- readiness: implementation_ready
+- risk_flags: [prompt-context, persistence, workflow-state, compaction]
+
+この Ticket は、active workflow を compaction / rehydration 後も継続可能にする concrete work item として十分に bounded されている。実装戦術の調査余地は残るが、Orchestrator が implementation routing できる要件・受け入れ条件・検証観点は揃っている。
+
+### Binding decisions / invariants
+
+- active workflow の進行中状態を、history に残らない transient context 注入だけで復元してはならない。
+- compaction / restore 後に「どの workflow が継続中か」「どの手順段階・義務が残っているか」をモデルが説明可能でなければならない。
+- workflow state の復元は、prompt context 加工原則に反しない形で durable source から再構成する。
+- missing / corrupt / obsolete workflow state は fail-closed または bounded diagnostic として扱い、silently stale instructions を実行しない。
+- Ticket / Pod history / workflow record / compaction output の authority boundary を混同しない。
+
+### Implementation latitude
+
+- workflow state の永続化先・schema・snapshot 粒度は、既存 Pod/session/compaction architecture に合わせて選んでよい。
+- active workflow body を invocation-time snapshot として保持するか、rehydration 時に最新 resource を参照するかは、実装時に明示的に決定し、互換性・安全性の理由をコードまたは docs / Ticket 報告に残す。
+- UI/diagnostic 表示の具体的な文言や internal field 名は、既存設計に沿って調整してよい。
+
+### Escalation conditions
+
+- workflow snapshot vs latest body の選択が authority boundary または backward compatibility を大きく変える場合。
+- compaction が workflow obligations を再現するために hidden context injection を必要としそうな場合。
+- persisted workflow state の migration / compatibility 方針が既存 records を破壊する場合。
+- implementation が Ticket lifecycle / Orchestrator queue semantics / workflow invocation semantics を広げる必要を見つけた場合。
+
+### Related context checked
+
+- closed `00001KTG3AZQ8` / `00001KTG3BX0R` は Orchestrator routing / merge completion の完了済み関連文脈であり、本 Ticket の duplicate ではない。

+## Intake summary
+
+既存 Ticket `00001KTFY8V80` を精査し、duplicate は作成しない方針で refinement を記録した。対象は active Workflow invocation/state/obligations を durable state/history と compaction/rehydration 経路に載せ、compaction 後も `/multi-agent-workflow` / `/worktree-workflow` などの active obligations を traceable に継続できるようにする実装 work item。readiness は implementation_ready。risk flags は prompt-context / persistence / workflow-state / compaction。Orchestrator は implementation routing 可能だが、snapshot vs latest workflow body の選択、hidden context injection 回避、missing/corrupt persisted state の fail-closed diagnostic、Ticket/Pod/history/workflow authority boundary を reviewer focus に含める。

+
+## Decision
+
+Routing decision: implementation_ready
+
+Reason:
+- Panel Queue により routing が明示的に許可され、Ticket は `queued`。
+- 要件、受け入れ条件、binding invariants、implementation latitude、escalation conditions が Ticket body/thread に揃っている。
+- active Workflow invocation/state/obligations を durable history/state と compaction/rehydration 経路に載せる目的は concrete で、残る不確実性は既存 Pod/session/compaction architecture 内の実装戦術選択に閉じている。
+
+Evidence checked:
+- Ticket body / thread / artifacts: artifacts なし、Intake refinement と `planning -> ready`、Panel `ready -> queued` を確認。
+- Ticket relations: blocking relation なし。
+- OrchestrationPlan records: 既存 record なし。
+- Orchestrator workspace state: `/home/hare/Projects/yoi/.worktree/orchestration` は clean、queue commit `d311fe8f` 上。
+- Visible Pods: spawned child なし。
+- Bounded code map: workflow / compaction 関連は `crates/pod/src/compact/*`, `crates/pod/src/workflow/*`, `crates/pod/src/prompt/*`, `crates/session-store/src/*`, `crates/protocol/src/lib.rs`, `resources/workflows/*` が候補。
+
+IntentPacket:
+
+Intent:
+- compaction を跨ぐ長時間 workflow-governed task で、active workflow と残る operational obligations が失われないようにする。
+
+Binding decisions / invariants:
+- Workflow instructions を、history/state に残らない turn-local transient context だけを根拠に model context へ注入しない。
+- post-compaction context は「available workflow」と「この task で active な workflow obligations」を区別する。
+- missing / corrupt / obsolete active workflow state は silent stale instruction ではなく fail-closed または bounded diagnostic にする。
+- Ticket / Pod history / workflow record / compaction output の authority boundary を混同しない。
+- active workflow state は workflow-governed task の完了または explicit cancellation で clear / completed にできる必要がある。
+
+Requirements / acceptance criteria:
+- active workflow の slug、invocation source/time、task/scope、active/completed、current obligations/checkpoints を durable typed history/state として表現する。
+- compaction が active workflow state を明示的に carry forward する。
+- rehydration が durable source から active workflow guidance を復元できる。
+- snapshot vs latest workflow body の選択を実装報告または docs/code に明示する。
+- focused coverage に、review delegation と merge/close handling の間で compaction が起きる worktree/multi-agent style flow を含める。
+
+Implementation latitude:
+- 永続化先、schema、snapshot 粒度、diagnostic 表現は既存 Pod/session/compaction architecture に合わせて選んでよい。
+- local tactic 調査は coder に委ねるが、authority boundary を広げる必要があれば escalate する。
+
+Escalate if:
+- workflow snapshot vs latest body の選択が authority boundary や backward compatibility を大きく変える。
+- compaction 復元が hidden context injection を必要としそうになる。
+- persisted workflow state migration / compatibility が既存 records を破壊しそうになる。
+- Ticket lifecycle / Orchestrator queue semantics / workflow invocation semantics を広げる必要が出る。
+
+Validation:
+- 変更箇所に応じて `cargo test` / `cargo check` の focused subset。
+- 少なくとも workflow/compaction 関連 unit coverage、`cargo fmt --check`、`git diff --check`。
+
+Current code map:
+- Primary candidates: `crates/pod/src/compact/*`, `crates/pod/src/workflow/*`, `crates/pod/src/prompt/*`, `crates/session-store/src/*`, `crates/protocol/src/lib.rs`。
+- Workflow resources: `resources/workflows/*`。
+
+Critical risks / reviewer focus:
+- hidden context injection 回避。
+- active vs advertised workflow の明確な区別。
+- stale workflow obligations の漏れ込み防止。
+- persisted state の compatibility / corrupt-state diagnostics。
+- compaction 後の traceability と test coverage。

+## Implementation report
+
+Implementation report from Coder Pod `yoi-coder-00001KTFY8V80`:
+
+Commit:
+- `362fedfb fix: preserve active workflows across compaction`
+
+Changed files:
+- `crates/pod/src/active_workflow.rs`
+- `crates/pod/src/lib.rs`
+- `crates/pod/src/pod.rs`
+- `crates/pod/src/segment_log_sink.rs`
+- `resources/prompts/internal/compact_system.md`
+
+Implemented behavior:
+- Added durable typed active workflow state as session-log extension domain `pod.active_workflows`.
+- State records include:
+  - workflow slug
+  - invocation source/time
+  - task scope
+  - active/completed/cancelled status
+  - snapshotted workflow guidance
+  - extracted obligations/checkpoints
+  - completion/cancellation reason/time
+- Workflow bodies are snapshotted at invocation time rather than resolved to latest resource/builtin version during rehydration. Rationale: active workflow authority remains traceable to the original governed task and does not silently change when resource files change later.
+- Compaction now:
+  - feeds active workflow state into compact worker input
+  - writes active workflow state into the replacement segment as typed extension state
+  - injects post-compaction workflow guidance into `SegmentStart.history` from durable state, not transient turn-local data
+- Added `ActiveWorkflowList`, `ActiveWorkflowComplete`, and `ActiveWorkflowCancel` tools so active workflow state can be inspected, completed, or explicitly cancelled.
+- Missing/corrupt/unsupported active workflow extension state fails closed with bounded diagnostics rather than reusing stale prior state.
+
+Validation reported by coder:
+- Passed: `cargo fmt --check`
+- Passed: `git diff --check`
+- Passed: `cargo test -p pod active_workflow --lib`
+  - includes focused coverage for review/merge/close-style obligations crossing compaction/rehydration
+- Passed: `cargo test -p pod includes_active_workflow_snapshot_section --lib`
+- Ran: `cargo test -p pod --lib`
+  - Failed on 2 prompt text assertions reported as unrelated/pre-existing:
+    - `prompt::catalog::tests::pod_orchestration_guidance_section_renders_resource_body`
+    - `prompt::system::tests::pod_orchestration_guidance_is_included_for_pod_management_tools`
+    - both assert the unrelated string `worktree status, diff, and test results`
+
+Repository status:
+- Child implementation worktree clean after commit.
+
+Residual risks / notes:
+- Active workflow obligation extraction is intentionally conservative: it stores full snapshotted guidance as authority and derives bounded checkpoint labels from obligation-like lines.
+- Completion/cancellation tool calls persist through normal history; compaction additionally writes updated typed snapshot into the compacted segment.

+## Review: request changes
+
+Review result: request_changes
+
+Evidence checked:
+- Child worktree/branch/head:
+  - `/home/hare/Projects/yoi/.worktree/00001KTFY8V80-active-workflows-compaction`
+  - `impl/00001KTFY8V80-active-workflows-compaction`
+  - HEAD `362fedfbe6689886f1e2e7c29da61e39b0ce1e38`
+  - merge base with requested base: `73d0a6a4`
+- `git status --short` was clean.
+- Diff `73d0a6a4..362fedfb` inspected.
+- Read-only validation:
+  - Passed: `git diff --check 73d0a6a4..362fedfb`
+- Cargo/fmt not rerun because review scope was read-only.
+
+What looks good:
+- A typed active workflow snapshot was added with slug, status, invocation source/time, task scope, snapshot policy, snapshotted guidance, obligations/checkpoints, and completion metadata.
+- Active workflow state is separated from advertised workflows; activation comes from invoked `SystemItem::Workflow` rather than resident workflow catalog.
+- Snapshot-vs-latest behavior is explicit via `WorkflowBodySnapshotPolicy::SnapshottedAtInvocation`.
+- Compaction passes active workflow state into compactor input and writes typed `LogEntry::Extension` into the compacted segment.
+- Clear/cancel tools are exposed as `ActiveWorkflowComplete` / `ActiveWorkflowCancel`.
+
+Required changes:
+
+1. Stale active workflow guidance can remain in prompt history after typed state is invalid, completed, or cancelled.
+
+- The implementation writes active workflow rehydration guidance as an ordinary system message in compacted history (`pod.rs` around the compaction replacement history construction).
+- Restore later uses `SegmentStart.history` as worker history.
+- Corrupt/obsolete extension handling drops/diagnoses the typed state but does not remove the old `[Active workflow snapshot]` system message from compacted history.
+- Therefore the model can still see stale workflow obligations even when the durable active-workflow extension is missing/corrupt/obsolete.
+- The same leakage risk applies after completion/cancellation: old compacted system messages can remain until another compaction.
+
+Required fix:
+- Ensure active workflow guidance shown to the model is gated by currently valid active workflow state, not immutable old compacted history.
+- For example, regenerate guidance from validated typed state at context/compaction time, or sanitize/supersede old active workflow system messages when typed state is invalid/inactive.
+- Add focused coverage for compacted history containing an active workflow message plus missing/corrupt/obsolete extension, and for completion/cancellation after compaction.
+
+2. Completion/cancellation durability is inferred from generic tool-call history and trusts bare `ToolCall`s.
+
+- `ActiveWorkflowComplete` / `ActiveWorkflowCancel` mutate only the in-memory store in the tool implementation.
+- They do not append a new typed `LogEntry::Extension` on successful status change.
+- Restore reconstructs completion/cancellation by scanning history.
+- Replay marks workflows completed/cancelled based solely on `Item::ToolCall` names, without requiring a matching successful `ToolResult`.
+
+Required fix:
+- Persist status changes as typed durable active workflow state when the status tool succeeds, or make replay validate a matching non-error tool result/event proving the tool executed successfully.
+- Add focused tests for interrupted/unmatched/error status tool calls.
+
+Prompt-test failure assessment:
+- The reported `cargo test -p pod --lib` failures about `worktree status, diff, and test results` appear unrelated. The diff changes `resources/prompts/internal/compact_system.md`, while the failing assertions are in pod orchestration prompt tests and reference a different prompt resource.
+
+Conclusion:
+- Changes requested. Do not integrate until stale-guidance gating and completion/cancellation durability are fixed and covered.

+## Implementation report
+
+Follow-up implementation report after reviewer request_changes:
+
+New commit:
+- `ff446052 fix: gate active workflow rehydration state`
+
+Changed files in follow-up:
+- `crates/pod/src/active_workflow.rs`
+- `crates/pod/src/ipc/interceptor.rs`
+- `crates/pod/src/pod.rs`
+
+Review blocker 1 resolved: stale active workflow guidance in prompt history
+- Active workflow rehydration guidance is no longer persisted into compacted `SegmentStart.history` as an ordinary system message.
+- Compaction still carries active workflow state forward via typed `pod.active_workflows` extension state.
+- Request context is sanitized before model calls:
+  - stale `[Active workflow snapshot]` system messages are stripped,
+  - current active workflow guidance is regenerated request-locally from validated typed state,
+  - when typed state is missing/corrupt/obsolete/inactive and stale workflow hints are present, a bounded inactive-state message supersedes old compacted references.
+- Restore paths strip stale active workflow rehydration messages before installing worker history.
+- Compaction source/retained histories strip old active workflow rehydration messages so old snapshots are not re-summarized as active authority.
+
+Review blocker 2 resolved: completion/cancellation durability
+- `ActiveWorkflowComplete` / `ActiveWorkflowCancel` now persist successful status changes by committing a new typed `LogEntry::Extension` snapshot through the session log writer.
+- Restore no longer infers completion/cancellation from bare `Item::ToolCall` history.
+- Typed extension state is the authority, avoiding trust in unmatched/interrupted/error tool calls.
+
+Focused coverage added/updated:
+- Compacted history containing active workflow rehydration message plus:
+  - missing extension,
+  - corrupt extension,
+  - obsolete extension.
+- Completion/cancellation after compaction suppressing old compacted guidance.
+- Successful status tool writes a typed durable extension.
+- Unmatched/error status tool calls do not mutate restored active workflow state.
+- Existing review/merge/close workflow obligation coverage still passes.
+
+Validation reported by coder:
+- Passed: `cargo fmt --check`
+- Passed: `git diff --check`
+- Passed: `cargo test -p pod active_workflow --lib`
+  - 7 passed
+- Passed: `cargo test -p pod interceptor --lib`
+  - 19 passed
+- Ran: `cargo test -p pod --lib`
+  - Still fails only on the previously reported unrelated prompt assertion failures:
+    - `prompt::catalog::tests::pod_orchestration_guidance_section_renders_resource_body`
+    - `prompt::system::tests::pod_orchestration_guidance_is_included_for_pod_management_tools`
+    - both assert missing text: `worktree status, diff, and test results`
+    - result: `332 passed; 2 failed`
+
+Repository status:
+- Child implementation worktree clean after follow-up commit.

+- Child worktree:

+- HEAD: `ff446052 fix: gate active workflow rehydration state`
+- Base checked against: `73d0a6a4`
+- Original implementation checked where relevant: `362fedfb`
+
+Prior blocker 1: stale active workflow guidance after compaction
+- Resolved.
+- Active workflow rehydration is now derived from typed `LogEntry::Extension` state via `ActiveWorkflowStore`, not from ordinary prompt/tool-call history.
+- Restore strips prior `[Active workflow snapshot]` system messages before installing history.
+- Rehydration guidance is regenerated request-time from validated active typed state.
+- Missing/corrupt/unsupported extension state fails closed: no active workflow restored, stale rehydration messages stripped, and bounded inactive diagnostic text tells the model not to treat older compacted history/summaries as active workflow authority.
+- Completed/cancelled typed state does not regenerate active guidance.
+- Compaction no longer stores active workflow guidance directly in `SegmentStart.history` as ordinary durable prompt authority; it carries typed extension entries.
+- Focused coverage exists for stale active workflow message plus missing/corrupt/unsupported state and completion/cancellation after compaction.
+
+Prior blocker 2: completion/cancellation durability
+- Resolved.
+- `ActiveWorkflowComplete` / `ActiveWorkflowCancel` mutate store status and commit a fresh typed `LogEntry::Extension` snapshot through the active workflow log committer.
+- Production controller wiring attaches the log writer before feature/tool registration, so status tools have durable commit plumbing.
+- Restore no longer trusts bare unmatched `Item::ToolCall` entries or failed/error calls to infer completed/cancelled state.
+- Focused tests cover unmatched/error status tool calls and explicit completed/cancelled typed extension suppression of active guidance.
+
+Overall acceptance:
+- Durable typed active workflow representation exists.
+- Compaction carries active workflow state forward through typed extension state.
+- Rehydration restores guidance from durable validated state.
+- Snapshot-vs-latest policy is explicit and fail-closed on missing/corrupt/unsupported latest state.
+- No hidden context injection from non-durable transient data was found.
+- Active vs advertised workflow separation is preserved.
+- Clear/cancel/complete behavior is durable typed-state transition.
+
+Validation performed by reviewer:
+- Passed: `git diff --check 73d0a6a4..HEAD`
+- Passed: `cargo fmt --check`
+- `git status --short` remained clean.
+
+Validation not rerun by reviewer:
+- Cargo tests were not rerun because review scope was read-only and tests write build artifacts. Coder-reported focused test results were inspected as evidence.
+
+Full-suite prompt failure assessment:
+- The remaining reported `cargo test -p pod --lib` prompt assertion failures involving `worktree status, diff, and test results` appear unrelated to the active workflow typed-state/compaction changes.
+
+Conclusion:
+- Approved. No remaining blocker found.

 ## Background
 
-MCP integration を concrete work item として実装する前に、Yoi の `pod::feature` / Worker / ToolRegistry 境界が外部 protocol-backed capability provider を自然に扱える必要がある。
+Yoi needs `pod::feature` to serve as the common API substrate for capabilities that contribute Tools / Hooks / Services / BackgroundTasks. External protocol-backed providers such as MCP need to discover contributions at startup and expose them through the same Worker / ToolRegistry / permission / history / bounded-result paths as built-in tools.
 
-現行の `pod::feature` API は static descriptor / static tool contribution / host authority grant を中心にしており、MCP のように startup 時の protocol negotiation と discovery によって tools/resources/prompts surface が決まる provider には不足がある。MCP 実装側でこれを ad-hoc に迂回すると、permission、history、bounded result、service lifecycle、feature/plugin boundary が歪む。
+This Ticket defines the feature-layer API required for those providers. It does **not** define Plugin package permissions, MCP server trust policy, local process sandboxing, or a feature-level authority model. Plugin and MCP are separate layers that build on the feature API and own their own user-facing configuration and permission/trust decisions.
 
-Objective context: `00001KTR80WMN`。
+Objective context: `00001KTR80WMN`.
 
 ## Requirements
 
-- `pod::feature` が external protocol-backed capability provider を表現できるようにする。
+- Treat `pod::feature` as the API layer for contribution registration and lifecycle integration.
-- local subprocess を起動する authority を明示的に表現する。
+  - Feature code exposes contribution types and installation/runtime hooks.
-  - 既存の filesystem/network/service authority に押し込まない。
+  - Feature code does not decide Plugin trust, MCP enablement, or external-provider permissions.
-  - command / args / cwd / env / secret refs は explicit config/grant に基づく。
+  - Do not add or rely on `HostAuthority` / authority grants for MCP, Plugin, or provider-process permissions.
-- Pod lifetime に紐づく feature-provided service / connection manager の lifecycle を表現できるようにする。
+- Add a feature-owned provider/service lifecycle surface sufficient for protocol-backed providers.
-- startup / initialize / discovery 後に tool contribution を登録または更新できる host-mediated API を設計する。
+  - startup / ready / failed / stopped diagnostics
-- dynamic contribution は通常の ToolRegistry / PreToolCall permission / history / bounded tool-result path を迂回しない。
+  - Pod lifetime integration and deterministic shutdown hooks
-- tool metadata に、MCP など外部 provider が持つ追加 metadata を安全に保持・変換できる余地を作る。
+  - provider failure state that makes dependent dynamic tools unavailable with a clear diagnostic
-  - title
+- Add dynamic contribution registration for startup-discovered tools.
-  - output schema
+  - discovery happens before the tool schema is exposed to a model request
-  - annotations
+  - registered tools use stable namespacing and normal ToolRegistry registration
-  - icons or display metadata
+  - tool schema changes during an active run do not silently mutate the model-visible schema
-  - execution/task-support metadata
+- Define bounded refresh semantics for provider list changes.
-- rich / structured tool result を bounded serialization できる共通 path を用意する。
+  - initial implementation may defer live refresh to a turn boundary or report restart/reinitialize-required diagnostics
-- capability metadata / schemas / descriptions / results は untrusted data として扱う。
+  - silent stale or mid-run schema mutation is not allowed
-- live list-changed / registry refresh が current run の tool schema consistency を壊さない方針を決める。
+- Define provider metadata / schema / result normalization as untrusted data.
-- API 拡張は MCP 固有名に寄せすぎず、将来の external plugin / bridge provider にも使える feature boundary として設計する。
+  - descriptions, schemas, annotations, titles, and provider metadata cannot weaken system/developer instructions
+  - structured / rich results are converted through a bounded Yoi representation before entering history/model-visible output
+- Ensure dynamic tool calls do not bypass normal Yoi paths.
+  - PreToolCall permission hooks still run
+  - permission denial prevents the provider call
+  - tool results and errors are committed through normal history/result plumbing
+- Keep MCP-specific protocol details in Ticket `00001KTR82RB7`.
+  - command / args / cwd / env / stdio JSON-RPC / MCP lifecycle are MCP-layer concerns

+  - Plugin packages/configs may use the feature API to contribute capabilities
+  - Plugin permission/trust policy belongs to the Plugin layer, not `pod::feature`
 
 ## Acceptance criteria
 
-- external protocol-backed provider を built-in feature として表現できる API がある。
+- `pod::feature` can represent a provider/service that becomes ready, fails, and stops with install/runtime diagnostics visible to the host.
-- subprocess execution authority が `HostAuthority` または同等の明示 grant として型で表現されている。
+- A mock protocol-backed provider can register at least one startup-discovered dynamic tool before the first model request that would expose its schema.
-- feature-owned long-running service lifecycle を Pod lifetime に接続できる。
+- The dynamic tool is registered as an ordinary Yoi tool and is visible through the same model-visible schema path as built-in tools.
-- discovery 後の dynamic tool contribution が通常 ToolRegistry と permission path に統合される。
+- A PreToolCall permission denial for the dynamic tool prevents the mock provider from receiving a call.
-- external metadata / schema / result content が untrusted data として扱われる設計になっている。
+- Provider failure makes dependent dynamic tools unavailable with a bounded, comprehensible diagnostic rather than panic or stale silent failure.
-- `list_changed` 相当の dynamic registry change について、safe refresh / next-turn refresh / restart-required diagnostic のいずれかが明示され、silent stale にならない。
+- Oversized or structured provider result data is bounded before being committed as a tool result.
-- MCP 実装 Ticket が private/ad-hoc API ではなく、この拡張 API に乗って実装できる見通しがある。
+- A simulated list-changed/schema-change event is handled by a documented safe path: turn-boundary refresh, restart/reinitialize-required diagnostic, or explicit unsupported diagnostic.
-- focused tests で authority grant、dynamic registration、permission denial、bounded result、service diagnostics を確認できる。
+- Tests/docs make clear that `pod::feature` is not the Plugin permission layer and not the MCP server trust/sandbox layer.
-- Validation: relevant crate tests、`cargo fmt --check`、`cargo check --workspace --all-targets`、`nix build .#yoi`。
+- No new `HostAuthority` / authority-grant dependency is introduced for external providers, Plugin permissions, or MCP local stdio execution.
+- Validation: focused feature/provider tests, affected crate tests, `cargo fmt --check`, `cargo check --workspace --all-targets`, and `nix build .#yoi`.
 
 ## Binding decisions / invariants
 
-- ToolRegistry / permission / history / bounded result の既存経路を迂回する API は作らない。
+- `pod::feature` is an API/contribution substrate, not a security or trust-policy layer.
-- external provider 由来の schema / description / annotation / content は instruction ではなく untrusted data として扱う。
+- Plugin is a user-facing package/config/runtime layer that uses `pod::feature`; Plugin permissions are Plugin-layer policy.
-- process execution は explicit authority として分離し、filesystem/network authority から暗黙に派生させない。
+- MCP is a separate feature-backed integration layer; MCP enablement, local server trust, and MCP-specific permissions are MCP-layer policy.
-- dynamic registry update は prompt/tool schema consistency と cache behavior を壊さないよう、turn boundary または restart/reinitialize diagnostic を持つ。
+- Dynamic provider contributions must enter through ordinary Worker / ToolRegistry / permission / history / bounded-result paths.
-- MCP specific shortcut ではなく、`pod::feature` の長期的な extension surface として成立させる。
+- Model-visible tool schemas are stable for the duration of a model request/run.
+- External provider metadata and output are untrusted content.
 
-## Implementation latitude
+## Out of scope
 
-- exact type names、crate placement、service handle の形、dynamic registration timing は実装側に委ねる。
+- MCP protocol implementation and local stdio transport details.
-- 初期実装では rich content を provider-native multimodal block として渡さず、bounded structured text/JSON serialization に寄せてもよい。
+- Plugin package format, distribution, provenance, and Plugin runtime permission grants.
-- live registry refresh が大きい場合は、まず restart/reinitialize-required diagnostic でもよい。ただし silent stale は避ける。
+- OS-level sandboxing of external provider processes.
+- Removing all existing `HostAuthority` code from the repository; cleanup is tracked separately by `00001KV0SP0TY` unless directly necessary for this API slice.
 
 ## Escalation conditions
 
-- current Worker / ToolRegistry architecture では dynamic contribution を安全に扱えない場合。
+- The feature API appears to need policy decisions about Plugin trust or MCP server permissions.
-- process execution authority と profile/config authority の責務境界が曖昧になる場合。
+- Dynamic registry refresh would require mutating model-visible tool schema during an active run.
-- rich content を model-provider native content block に渡す必要が出た場合。
+- Provider result normalization would require provider-native multimodal blocks to bypass normal bounded tool-result serialization.
-- hook / feature / plugin contribution boundary の既存設計と矛盾する場合。
+- MCP implementation pressure suggests adding private ToolRegistry/history/context bypasses instead of extending the feature API.

+## Decision
+
+決定:
+- `pod::feature` は API / contribution substrate として扱い、Plugin や MCP の権限管理を担わせない。
+- Plugin は `pod::feature` をユーザー向け package/config/runtime 形式で使わせる層であり、Plugin permission / trust policy は Plugin layer で定義する。
+- MCP は `pod::feature` 上に protocol-backed integration layer を構築するが、MCP server enablement / command-env-secret policy / trust boundary / MCP-specific permission は MCP layer が独自に持つ。
+- MCP local stdio server の OS-level side effects は Yoi feature authority では制御できないため、feature-layer authority / grant を MCP や Plugin の permission model に流用しない。
+
+反映:
+- `00001KTR81P9X` は authority ではなく provider lifecycle / dynamic contribution / normal ToolRegistry path / untrusted normalization に絞る。
+- `00001KTR82RB7` は MCP 固有の explicit config と trust model を持つ。
+- `00001KSXRQ4G8` と `00001KT0Z4BK8` は Plugin permission を Plugin layer として扱い、MCP を初期 Plugin packaging/runtime から分離する。

+
+Routing decision: implementation_ready
+
+Reason:
+- Ticket is queued and requirements/acceptance criteria for feature-layer provider/service lifecycle and dynamic contributions are specified.
+- Outgoing `depends_on 00001KV0SP0TY` is satisfied: HostAuthority cleanup is done and merged.
+- Relation/orchestration plan checks show no remaining blocker.
+- Scope is API/contribution substrate only; Plugin/MCP permission/trust policy remains out of scope.
+
+IntentPacket:
+- Extend `pod::feature` so protocol-backed providers can contribute startup-discovered tools/services/background lifecycle diagnostics through ordinary ToolRegistry / Worker / permission / history / bounded-result paths.
+
+Binding invariants:
+- Do not introduce `HostAuthority` or replacement feature-layer authority grants.
+- Do not implement MCP protocol/trust policy or Plugin permission policy here.
+- Dynamic schemas must be stable for a run; provider metadata/output is untrusted; tool calls must go through normal permission/history/result paths.
+
+Validation:
+- focused feature/provider tests, affected crate tests, `cargo fmt --check`, `git diff --check`, `cargo check --workspace --all-targets`, and `nix build .#yoi` if feasible.

+## Implementation report
+
+Implemented provider feature API for Ticket 00001KTR81P9X.
+
+Summary:
+- Extended `pod::feature` descriptors with `ProtocolProviderDeclaration` and provider lifecycle state/diagnostic reporting.
+- Added `ProtocolProviderContribution` and `FeatureInstallContext::protocol_providers()` so startup-discovered provider tools, services, and background task declarations register through the existing feature install pipeline.
+- Provider tools are materialized once at startup and then installed as ordinary Worker tool definitions, preserving stable schemas for the run and normal permission/history/bounded-result execution paths.
+- Unavailable providers record lifecycle diagnostics and skip discovered contributions without adding a separate feature authority layer.
+- Added focused tests for ready providers, failed providers, undeclared providers, and stable dynamic tool metadata.
+
+Validation:
+- PASS: `cargo fmt --check`
+- PASS: `cargo test -p pod feature::tests`
+- PASS: `cargo check --workspace --all-targets`
+- PASS: `git diff --check`
+- FAIL (pre-existing/unrelated prompt assertion): `cargo test -p pod` fails in `prompt::catalog::tests::pod_orchestration_guidance_section_renders_resource_body` and `prompt::system::tests::pod_orchestration_guidance_is_included_for_pod_management_tools`, both expecting the phrase `worktree status, diff, and test results`.
+- FAIL (environment/resource): `nix build --no-link .#yoi` compiles through the Rust crates but fails during final binary link with `No space left on device`.
+
+Risks/notes:
+- This does not implement MCP protocol, MCP trust policy, plugin permissions, subprocess management, or a replacement HostAuthority-style grant layer.
+- Provider metadata and diagnostics remain install-report data; actual provider tool execution goes through the normal Worker/tool machinery.

+## Review: approve
+
+## Review: approve
+
+Reviewed implementation commit `053a4f90` against Ticket `00001KTR81P9X` and base routing commit `f709fc10`.
+
+Evidence:
+- Diff is limited to the Ticket record and `crates/pod/src/feature.rs`.
+- The provider API extension stays in `pod::feature` as a contribution/reporting substrate: `ProviderId`, `ProtocolProviderDeclaration`, `ProtocolProviderLifecycleState`, `ProtocolProviderContribution`, lifecycle diagnostics, and `FeatureInstallContext::protocol_providers()` were added without introducing `HostAuthority`, grant replacement types, MCP trust policy, plugin permission policy, subprocess management, or ToolRegistry/history bypasses.
+- Startup-discovered provider tools are materialized once during feature installation and then registered through `Worker::register_tools`, preserving stable schemas for the run and normal Worker permission/history/result machinery.
+- Ready providers can contribute tools, service declarations, and background task declarations through the existing feature install report/registry surfaces; unavailable providers record lifecycle diagnostics and skip discovered contributions instead of panicking or installing stale tools.
+- Diagnostics cover undeclared provider ids, duplicate tool names through the shared tool registrar, and failed lifecycle states.
+- API shape is type-oriented and localized; I did not find broad compatibility glue or authority-layer leakage.
+
+Validation performed:
+- PASS `cargo fmt --check`
+- PASS `git diff --check f709fc10..HEAD`
+- PASS `cargo test -p pod feature::tests` (17 passed)
+- PASS `cargo check --workspace --all-targets`
+- FAIL `cargo test -p pod`: 323 passed / 2 failed in the same prompt assertion tests reported by Coder (`prompt::catalog::tests::pod_orchestration_guidance_section_renders_resource_body`, `prompt::system::tests::pod_orchestration_guidance_is_included_for_pod_management_tools`, both expecting `worktree status, diff, and test results`). The reviewed diff does not touch prompt resources or those prompt modules, so I classify this as unrelated/pre-existing for this Ticket.
+
+Risks / notes:
+- I did not rerun `nix build`; Coder reported a final-link `No space left on device` after Rust compilation. Focused Rust validation passed.
+- Permission denial and bounded-result behavior are not reimplemented in this diff; they are intentionally inherited because provider tools are installed as ordinary Worker tools.

+- `git diff --check`: PASS
+- `cargo test -p pod feature::tests`: PASS
+- `cargo check --workspace --all-targets`: PASS
+
+Not run:
+- `nix build .#yoi`: skipped at integration because prior Coder run hit host disk pressure during final link; this change did not modify dependencies, Cargo.lock, packaging, or source filters. Recent package validation was performed on adjacent E2E/Profile work.
+
+Residual notes:
+- Full `cargo test -p pod` is known to fail unrelated prompt assertion tests expecting old guidance text. Reviewer classified those as unrelated/pre-existing to this feature API diff.

-## 背景
+## Background
 
-LocalTicketBackend によって作成されました。
+`yoi.profile.extend(base, overrides)` は base Profile と override object を Rust 側で deep merge する convenience API だった。しかし deep merge semantics が隠れるため、object field を「置換したい」のか「部分 merge したい」のかが Profile authoring 上で読み取りづらい。
 
-## 受け入れ条件
+今回の問題では、以下のような Profile が scope を置換するつもりで object を渡すと、`builtin:default` 側の inherited value と deep merge され、workspace write が残り得た。
 
-- 未定
+```lua
+return yoi.profile.extend("builtin:default", {
+  scope = yoi.scope.workspace_read(),
+})
+```
+
+一方で Lua には通常の table 操作があるため、Profile 継承と field replacement は次の形で明示できる。
+
+```lua
+local p = yoi.profile.import("builtin:default")
+p.worker.instruction = "$yoi/role/orchestrator"
+p.feature.task.enabled = false
+p.feature.ticket = { enabled = true, access = "lifecycle" }
+return p
+```
+
+この形なら、top-level/nested field の代入は ordinary Lua assignment であり、merge/replace の意図が読みやすい。Profile scope については別 Ticket `00001KV11DHGZ` で concrete runtime authority を launch policy に移すため、`extend()` に replacement API を足す必要性はさらに下がった。
+
+## Requirements
+
+- `yoi.profile.extend` を廃止する。
+  - builtin Profile resources は `extend()` を使わず、`yoi.profile.import(...)` + explicit Lua assignment に移行する。
+  - Profile authoring convention は ordinary Lua table mutation / assignment を基本とする。
+- `yoi.profile.import` は残す。
+  - base Profile を取得して手元で変更し、`return p` する構造を公式パターンにする。
+- `extend()` の deep merge semantics に依存する builtin tests/resources を更新する。
+- `extend()` を public API として残す場合は deprecated diagnostic を出すか、削除して明確に fail させる。
+  - どちらにするかは実装時に決めてよいが、builtin resources は使わない。
+  - 不必要な compatibility alias は作らない。
+- Docs/tests/comments から「scope replacement API を足す」方向の記述を削除する。
+  - scope/delegation_scope の concrete authority は `00001KV11DHGZ` の launch policy 側で扱う。
+  - scope 以外でも object replacement が必要な場合は ordinary Lua assignment を使う。
+- Profile merge helper がどうしても必要になった場合は、`extend()` のような曖昧な名前ではなく、`deep_merge` / `shallow_merge` など semantics が明示された別 API として後続 Ticket で検討する。
+
+## Acceptance criteria
+
+- Repository builtin Profile resources no longer call `yoi.profile.extend`.
+- The Profile Lua API supports the official inheritance pattern:
+
+```lua
+local p = yoi.profile.import("builtin:default")
+-- mutate p explicitly
+return p
+```
+
+- Tests cover that `import()` + assignment replaces object fields without deep merge surprise.
+- Existing role Profiles still resolve to the same intended non-scope behavior: worker instructions, feature enablement, model/defaults, compaction, etc.
+- If `extend()` is removed, calling it fails with a clear Lua/profile error. If deprecated instead, it emits/records a clear deprecation diagnostic and builtin resources do not use it.
+- The old requirement to add `yoi.scope.replace(...)` / `replace = true` for scope replacement is removed or explicitly superseded.
+- Validation: focused profile resolution tests and `cargo build -p yoi`. Run `nix build .#yoi` only if resource packaging or lockfile/package changes require it.
+
+## Non-goals
+
+- Moving concrete scope/delegation_scope out of Profiles; tracked by `00001KV11DHGZ`.
+- Designing a general-purpose Lua table utility library.
+- Preserving `extend()` compatibility indefinitely.
+- Plugin/MCP permission design.
+
+## Related work
+
+- Move concrete scope to launch policy: `00001KV11DHGZ`
+- Original scope replacement concern is superseded by this Ticket plus `00001KV11DHGZ`.

+
+Reason:

+- Risk is bounded to Lua Profile API/resources/tests.

+- Migrate builtin Profile resources away from `yoi.profile.extend`, keep `import`, and make `extend` fail clearly or emit a deprecation diagnostic. Remove docs/tests that suggest scope replacement APIs.
+
+Binding invariants:
+- Do not solve concrete scope/delegation authority here; that belongs to `00001KV11DHGZ`.
+- Do not add ambiguous replacement/clear API as part of `extend`.
+- Builtin resources must use import + explicit Lua assignment.
+

+## Implementation report
+
+Implemented removal/deprecation of yoi.profile.extend and migrated builtin role Profile resources to yoi.profile.import plus explicit Lua assignment.
+
+Changes:
+- yoi.profile.extend now fails with a removed-API diagnostic directing users to yoi.profile.import(...) plus assignment; the previous JSON deep-merge implementation was removed.
+- Builtin role Lua profiles (companion/intake/orchestrator/coder/reviewer) import builtin:default, then assign each overridden field explicitly. Worker instruction overrides preserve imported worker defaults by assigning p.worker.instruction.
+- Focused profile tests now cover explicit assignment, object replacement without hidden deep-merge retention, removed extend diagnostics, and role profile resolution/feature policy.
+
+Validation:
+- cargo fmt --check
+- git diff --check
+- cargo test -p manifest profile::tests:: -- --nocapture
+- cargo build -p yoi
+- nix build .#yoi (completed; dirty-tree warning expected before commit, result symlink removed)
+
+Risks/notes:
+- yoi.profile.extend remains present only as a failing diagnostic stub so callers receive an actionable migration error instead of a nil-call Lua error.
+- Scope/delegation authority semantics were not expanded; this change only preserves existing builtin profile scope/delegation declarations while changing composition style.

+- `approve`。`yoi.profile.extend` deep-merge composition is removed, builtin role profiles use `yoi.profile.import("builtin:default")` plus explicit Lua assignment, and no scope/delegation authority semantics were expanded into this Ticket.
+
+Orchestrator validation after merge:
+- `cargo fmt --check`: PASS
+- `git diff --check`: PASS
+- `cargo test -p manifest profile::tests:: -- --nocapture`: PASS
+- `cargo build -p yoi`: first attempt failed due to disk full during Rust metadata output; after stopping/removing profile child Pods/worktree/target, rerun PASS
+- `nix build .#yoi`: PASS (result symlink produced)
+
+Cleanup already performed before rerun validation to free disk:
+- stopped `coder-00001KTZY8HK2-profile-extend` and `reviewer-00001KTZY8HK2-profile-extend`
+- removed child worktree `/home/hare/Projects/yoi/.worktree/profile-extend-removal`
+- deleted branch `ticket-00001KTZY8HK2-profile-extend-removal`

+Residual notes:
+- Existing users of `yoi.profile.extend` will now get the intended removed-API diagnostic and must migrate to import + explicit Lua assignment.
+
+Next:
+- Mark Ticket done. Closure remains separate.
+- Re-evaluate queued `00001KV11DHGZ` because its profile-surface conflict wait on this Ticket is now resolved.

+## Comment
+
+Post-merge measurement report: Panel quit latency is still present / not proven fixed.
+
+User report:
+- 「相変わらずPanelをquitする際の遅延も解決してない」
+
+Measurement performed after merge in Orchestrator worktree `/home/hare/Projects/yoi/.worktree/orchestration/yoi-orchestrator`:
+- Built current debug binary: `cargo build -p yoi`。
+- PTY measurement command shape: pipe `sleep <delay>; Ctrl+C` into `script -q -c 'target/debug/yoi panel --workspace ...'` and measure process elapsed.
+- Current debug binary `target/debug/yoi` results with Ctrl+C sent after 1.5s:
+  - approx after Ctrl+C: 2488ms, 2561ms, 2453ms, 2558ms, 2507ms。
+- Varying Ctrl+C send delay against current debug binary:
+  - delay 0.2s -> total 3958ms
+  - delay 1.0s -> total 3919ms
+  - delay 2.0s -> total 4062ms
+  - delay 3.5s -> total 4095ms
+  - delay 5.0s -> total 6309ms
+- Installed `/home/hare/.nix-profile/bin/yoi` showed approx 24-25ms after Ctrl+C in the same scripted shape, and also appeared not to contain the new test/symbol strings, so binary-path freshness differs between measurements.
+
+Conclusion:
+- The original merge was based on a plausible code-path fix and focused tests, but no interactive/user-path latency measurement was done before marking done。
+- The current debug binary still shows a roughly 4s startup/quit floor in the PTY measurement, so the merged fix did not prove the user's observed latency is gone and may have missed a different blocking path。
+- Follow-up must identify the actual user command/binary path and measure `yoi panel` quit latency before and after any further fix. If the relevant path is current source/debug, this Ticket should be treated as not actually resolved.

+Post-merge user verification report: mouse selection is still ineffective.
+
+User report:
+- 「マウス選択全く効かない」
+
+What was re-checked:
+- Merge commit for this Ticket: `02311883 merge: panel mouse selection`。
+- Implementation added `PanelRowHitBox` / `TermEvent::Mouse` handling in `crates/tui/src/multi_pod.rs` and focused tests, but there was no interactive `yoi panel` manual validation before marking done。
+- Current built debug binary contains `PanelRowHitBox` symbols; installed `/home/hare/.nix-profile/bin/yoi` did not contain those symbols in `strings` check, so at least one live/user-visible binary path may still be stale。
+- This does not fully explain the report if the user already rebuilt/restarted; the remaining likely failure areas are terminal mouse-event delivery, runtime binary freshness, hitbox coordinate mismatch, or lack of interactive validation coverage。
+
+Conclusion:
+- The original done decision was insufficient because it relied on internal hit-test/focused tests and did not prove actual terminal mouse selection in a live Panel.
+- Follow-up must include measured/manual validation with the same command/binary path the user runs, including a positive proof that a click changes selected row in `yoi panel`.

+Routing decision: implementation_ready
+
+Reason:
+- Panel Queue により routing が明示的に許可され、Ticket は `queued`。
+- 要件、受け入れ条件、binding decisions / invariants、implementation latitude、escalation conditions、validation が Ticket body/thread に揃っている。
+- Panel 表示改善に限定された concrete work item であり、registry/schema redesign や自動 spawn/polling は非要件として明確。
+
+Evidence checked:
+- Ticket body / thread / artifacts: artifacts なし、Intake summary と `planning -> ready`、Panel `ready -> queued` を確認。
+- Ticket relations: blocking relation なし。
+- OrchestrationPlan records: 既存 record なし。
+- Orchestrator workspace state: `/home/hare/Projects/yoi/.worktree/orchestration` は clean、queue commit `d311fe8f` 上。
+- Visible Pods: spawned child なし。
+- Related code map: `crates/tui/src/workspace_panel.rs`, `crates/tui/src/multi_pod.rs`, `crates/tui/src/role_session_registry.rs`。
+
+IntentPacket:
+
+Intent:
+- Workspace Panel の Ticket 表示で、Ticket-associated Intake Pod/session を Ticket row と隣接・関連表示し、open/attach 対象として認識しやすくする。
+
+Binding decisions / invariants:
+- local Pod assignment / Pod name / socket / claim state / runtime status を git-tracked Ticket metadata/frontmatter/thread に保存しない。
+- automatic polling / automatic Intake spawn を追加しない。
+- selected arbitrary Pod direct-send UX を復活させない。
+- Ticket と Intake Pod の関係を 1:1 と仮定しない。
+- one-active-claim-per-Ticket invariant を維持する。
+- 既存 local role/session registry を基本入力とし、新しい durable Ticket schema は導入しない。
+
+Requirements / acceptance criteria:
+- Ticket に local Intake claim / related Intake session がある場合、Panel 上で Ticket と隣接・関連表示される。
+- subtitle に埋もれず「この Ticket の Intake Pod」と認識できる。
+- live / restorable / stale の状態が確認できる。
+- 関連 Intake Pod の open/attach 導線が Panel 操作から使える、または既存 open/attach 操作へ明確に誘導される。
+- pre-Ticket Intake Pod を特定 Ticket に誤関連付けしない。
+- focused test で ViewModel/row ordering または rendering contract を確認する。
+
+Implementation latitude:
+- 表示形式は既存 Panel UI に合わせて、隣接 row / child row / inline chip / row group のいずれかを選んでよい。
+- `related_pods` / `local_claim` ViewModel 拡張または typed row kind 追加は実装判断。
+- subtitle 表示の整理は重複して読みにくくならない範囲で可。
+
+Escalate if:
+- Panel selection model / keyboard semantics の大幅変更が必要になる。
+- one-active-claim-per-Ticket を崩さないと目的を満たせない。
+- pre-Ticket Intake と existing-Ticket Intake の表示分類が曖昧になり、誤関連付けのリスクがある。
+- Registry schema migration が必要になる。
+
+Validation:
+- `cargo test -p tui workspace_panel --lib`
+- 関連箇所を触る場合 `cargo test -p tui multi_pod --lib` / `cargo test -p tui role_session_registry --lib`
+- `cargo fmt --check`
+- `git diff --check`
+
+Current code map:
+- `crates/tui/src/workspace_panel.rs`
+- `crates/tui/src/multi_pod.rs`
+- `crates/tui/src/role_session_registry.rs`
+
+Critical risks / reviewer focus:
+- Ticket metadata 汚染の有無。
+- one-active-claim invariant。
+- pre-Ticket Intake の誤関連付け。
+- selection/open semantics の不要な変更。
+- bounded row rendering / large list readability。

+
+## Implementation report
+
+Implementation report from Coder Pod `yoi-coder-00001KV09WYC6`:
+
+Commit:
+- `2664cdd9 feat: show ticket intake pods in panel`
+
+Changed files:
+- `crates/tui/src/workspace_panel.rs`
+- `crates/tui/src/multi_pod.rs`
+
+Implemented behavior:
+- Workspace Panel derives Ticket-associated Intake Pods from the local role/session registry:
+  - active local Intake claim for a Ticket
+  - related Intake sessions whose `related_tickets` explicitly contain that Ticket id
+- Pre-Ticket Intake sessions without an explicit Ticket relation are not associated, even if the Pod name contains the Ticket id.
+- Ticket rows now get adjacent child rows:
+  - `↳ Intake Pod: <pod-name>`
+  - status column shows `live`, `restorable`, or `stale`
+  - non-stale associated Intake rows expose `Open/attach` behavior via the existing Pod open path
+  - stale rows show unavailable/stale reason instead of trying to open
+- Added typed row key/kind for Ticket Intake Pod rows:
+  - `PanelRowKey::TicketIntakePod`
+  - `PanelRowKind::TicketIntakePod`
+- Kept related display bounded with `MAX_ASSOCIATED_INTAKE_ROWS_PER_TICKET = 3`.
+- Preserved existing local claim handling for generic `related_pods`, while using the new typed `intake_pods` field for visible Ticket Intake child rows.
+- Updated panel selection/open plumbing so associated Intake rows resolve to existing Pod open/attach behavior.
+
+Focused coverage:
+- Added `workspace_panel_shows_ticket_associated_intake_pods_adjacent_to_ticket`, covering:
+  - local Intake claim adjacent row
+  - related Intake session adjacent row
+  - live status/action contract
+  - Pre-Ticket Intake session not falsely associated
+
+Validation reported by coder:
+- Passed: `cargo test -p tui workspace_panel --lib`
+- Passed: `cargo test -p tui role_session_registry --lib`
+- Passed: `cargo fmt --check`
+- Passed: `git diff --check`
+- Ran relevant: `cargo test -p tui multi_pod --lib`
+  - Failed in one existing environment/path-sensitive test:
+    - `tests::orchestrator_launch_uses_runtime_workspace_not_process_cwd`
+    - Failure expected `/tmp/.../runtime-workspace` but observed the worktree path.
+  - The suite compiled; coder assessed this as unrelated to the Intake-row changes.
+
+Repository status:
+- Child implementation worktree clean after commit.
+
+Residual risks / blockers:
+- No known implementation blocker.
+- Validation caveat: unrelated `multi_pod` filtered-suite failure noted above remains for reviewer/orchestrator assessment.

+
+## Review: approve
+
+Review result: approve
+
+Evidence checked:
+- Worktree clean and HEAD at implementation commit `2664cdd9`.
+- Ticket intent/body/thread reviewed from the child worktree.
+- Diff `73d0a6a4..2664cdd9` reviewed.
+- Changed files limited to:
+  - `crates/tui/src/workspace_panel.rs`
+  - `crates/tui/src/multi_pod.rs`
+- Read-only whitespace validation:
+  - `git diff --check 73d0a6a4..2664cdd9` passed.
+
+Acceptance / invariant review:
+- Ticket-associated Intake Pods are modeled as explicit `PanelRowKind::TicketIntakePod` rows with `PanelRowKey::TicketIntakePod { ticket_id, pod_name }`.
+- Rows are inserted immediately after the owning Ticket row, satisfying adjacent/clearly-related display.
+- Association comes from local role/session registry evidence: active local claim and Intake sessions with explicit `related_tickets`.
+- Pod-name-contains-ticket-id heuristic was removed, reducing false association risk and preserving the pre-Ticket Intake invariant.
+- Pre-Ticket Intake Pods without related Ticket evidence are not attached to Ticket rows; focused test covers this.
+- Multiple Intake entries per Ticket are supported and bounded by `MAX_ASSOCIATED_INTAKE_ROWS_PER_TICKET`; no 1:1 assumption.
+- one-active-claim-per-Ticket remains enforced by existing registry claim path; this change only reads/displays claims/sessions.
+- No git-tracked Ticket metadata/frontmatter/thread storage was added for Pod assignment/status.
+- No automatic polling or automatic Intake spawn was added.
+- Arbitrary selected Pod direct-send UX was not revived; associated Intake row routes through existing open/attach behavior.
+- live/restorable/stale status is surfaced via `TicketLocalClaimStatus::label()`.
+- Focused coverage exists for adjacent Intake rows and multi-pod selection/open behavior.
+
+Validation not rerun:
+- Cargo/fmt validation was not rerun because the review scope was read-only and those commands may write build artifacts.
+
+Reported `multi_pod` failure assessment:
+- `tests::orchestrator_launch_uses_runtime_workspace_not_process_cwd` appears unrelated. The implementation changes Workspace Panel row modeling/rendering/selection/open routing only and does not modify orchestrator launch workspace/cwd construction.
+
+Conclusion:
+- Approved. No blocker remains for integration.

+Routing decision: implementation_ready
+
+Reason:
+- Ticket は `queued` で、ready Ticket を Panel からユーザー指示付きで `planning` に戻し Intake を再開する action の intent / requirements / acceptance criteria / invariants が具体化されている。
+- `TicketRelationQuery` / `TicketOrchestrationPlanQuery` に blocker はない。
+- Risk は panel-action / ticket-lifecycle / role-session / authority-boundary だが、対象は `ready -> planning` のみ、typed backend 経由、Queue/Orchestrator/worktree/coder side effect 不発生という binding invariants が明記済み。
+- `00001KV0X254D` と同じ Panel 周辺に触れる可能性はあるが action dispatch と orchestration branch config は論理的に分離できる。merge conflict が出たらその Ticket を止めて報告する。
+
+Evidence checked:
+- Ticket body / thread / artifacts。
+- relation records: なし。
+- orchestration plan records: なし。
+- workspace state: Orchestrator worktree clean、dedicated child worktree で実装予定。
+
+IntentPacket:
+- Panel の ready Ticket row から Queue とは別に refinement/intake 再開 action を実行できるようにし、ユーザー指示を Ticket thread に保存して typed `ready -> planning` を記録し、Intake restore/launch を試行する。
+
+Binding decisions / invariants:
+- この action は implementation routing ではなく requirements sync への戻し。
+- `queued` / `inprogress` は範囲外。
+- stale state は再読込して拒否する。
+- Queue、`queued -> inprogress`、worktree 作成、coder/reviewer spawn は発生させない。

+## Implementation report
+
+Commit: `f74146c6` (`tui: return ready tickets to planning from panel`)
+
+Files changed:
+- `crates/tui/src/multi_pod.rs`
+
+What changed:
+- Added a separate Panel path for selected `ready` Ticket rows when the composer target is Ticket Intake and the user submits non-empty refinement instructions.
+- The action rereads the Ticket through the typed local Ticket backend and records a typed `ready -> planning` `state_changed` event with the user's refinement instruction in the Ticket thread.
+- The action does not invoke Queue, `queued -> inprogress`, worktree creation, or implementation-role spawning.
+- After the state change it attempts the Intake continuation path:
+  - launch and claim a new Intake Pod when no local Intake claim exists,
+  - notify a live claimed Intake Pod,
+  - open/restore a restorable claimed Intake Pod,
+  - or leave a visible diagnostic for stale claims without launching a duplicate.
+- Added focused tests for stale-state rejection, state/event recording, action dispatch selection, launch-after-mutation followup, and role-session claim recording for post-launch Intake Pods.
+
+Validation:
+- `cargo test -p tui planning_return`
+- `cargo test -p tui intake_registry`
+- `cargo test -p tui workspace_panel`
+- `cargo test -p ticket`
+- `cargo fmt --check`
+- `git diff --check`
+
+Residual risks:
+- No real terminal/PTTY Panel E2E was run; coverage is focused unit/action-path validation.
+- The existing Panel composer model exposes this via Ticket Intake target + selected ready row + non-empty text, rather than adding a new visible button/menu surface.
+
+---
+
+<!-- event: review author: hare at: 2026-06-13T19:07:43Z status: approve -->
+
+## Review: approve
+
+Evidence reviewed:
+- Inspected `git diff c4465a04..HEAD`; source changes are confined to `crates/tui/src/multi_pod.rs` plus Ticket record/report updates.
+- Panel dispatch now has a separate `ReturnReadyTicketToPlanning` path for non-empty composer text when the composer target is Ticket Intake and the selected row action is `Queue`/ready.
+- The mutation path reloads the Ticket from `LocalTicketBackend`, rejects non-`ready` current state, and records a typed `ready -> planning` `state_changed` event with author `workspace-panel`, reason `panel_return_to_planning`, and the user instruction in the thread body.
+- The follow-up paths are Intake-only: launch when unclaimed, notify live claimed Intake, open/restorable claimed Intake, or diagnose stale claim without duplicate launch. I did not find calls to queue dispatch, `queued -> inprogress`, worktree creation, Orchestrator/Coder/Reviewer spawn in this path.
+- Tests cover successful planning return, stale-state rejection, dispatch separation from Queue/generic Intake launch, state-before-launch follow-up, and launched-claim registry handling. Existing queue action coverage remains present.
+
+Validation run:
+- `cargo test -p tui planning_return` — pass (4 tests)
+- `cargo test -p tui intake_registry` — pass (4 tests)
+- `cargo test -p tui workspace_panel` — pass (12 tests)
+- `cargo test -p ticket` — pass (68 tests + doctests)
+- `cargo fmt --check` — pass
+- `git diff --check c4465a04..HEAD` — pass
+
+Residual notes:
+- No real terminal/PTTY Panel E2E was run; this remains a unit/action-path review only.
+- Discoverability depends on the existing composer target model: select a ready Ticket row, switch to Ticket Intake, type non-empty refinement instructions, then Enter. The implementation makes this visible in status/actionbar text; no separate button/menu was added.

+
+## Background
+
+Current `pod::feature` contains `HostAuthority`, `HostAuthorityRequest`, and `HostAuthorityGrantSet`. In practice this layer does not enforce OS-level or Plugin/MCP permissions: current install code grants requested authorities and uses them mostly as declaration/reporting and contribution registration checks.
+
+The project decision is to keep `pod::feature` as an API/contribution substrate and move real permission/trust decisions to the owning layers:
+
+- Plugin package/runtime permission policy belongs to the Plugin layer.
+- MCP local stdio enablement, command/env/secret policy, and server trust belong to the MCP layer.
+- filesystem/tool/pod permissions remain in existing manifest/profile/tool permission paths.
+- Ticket feature access remains explicit Ticket feature configuration and backend validation, not feature-layer authority grants.
+
+Therefore the feature-layer authority model should be removed, not renamed or preserved as diagnostics. Any remaining report data should use ordinary contribution/installation diagnostic terminology without `Authority`, `Grant`, or permission semantics.
+
+## Requirements
+
+- Remove `HostAuthority`, `HostAuthorityRequest`, `HostAuthorityGrantSet`, and related feature install report fields from `pod::feature`.
+- Do not introduce renamed feature-layer authority/grant types as a replacement; use ordinary diagnostics for non-permission install information.
+- Remove contribution registration checks that depend on feature-layer authority grants.
+- Keep contribution declaration/registration checks that are still useful without authority terminology.
+  - duplicate contribution names
+  - undeclared contribution categories, if currently checked
+  - feature install diagnostics
+- Update built-in features that currently request host authorities.
+  - Ticket feature should rely on validated `TicketFeatureConfig`, backend root validation, and access-level configuration.
+  - Task feature should not mention host authority.
+- Ensure no Plugin or MCP Ticket depends on feature-layer authority grants after the cleanup.
+- Update comments/docs/tests that describe feature-layer authority as future Plugin/MCP permission infrastructure.
+- Do not use this cleanup to introduce Plugin permission policy or MCP server trust policy; those remain separate layers.
+
+## Acceptance criteria
+
+- The codebase no longer exposes `HostAuthority*` or equivalent feature-layer authority/grant types as part of the `pod::feature` public API.
+- Built-in task and ticket feature tests pass without authority grants.
+- Ticket tools still require explicit Ticket feature config/access and validated backend root.
+- Feature install reports still provide useful diagnostics for skipped/failed contributions without implying security grants.
+- Grep/review confirms Plugin and MCP planning Tickets do not rely on feature authority for permission/trust control.
+- Validation: focused feature/ticket/task tests, `cargo fmt --check`, affected crate tests, `cargo check --workspace --all-targets`, and `nix build .#yoi`.

+## Decision
+
+Routing decision: implementation_ready
+
+Reason:
+- Ticket は `queued` で、feature-layer `HostAuthority*` model を削除し、permission/trust は Plugin/MCP/Ticket/tool owning layers に置く decision が明確。
+- `TicketRelationQuery` には incoming `depends_on`（`00001KTR81P9X` がこの Ticket に依存）があるが、この Ticket 自身を blocking する relation はない。むしろ後続 dynamic provider work の前提として先に進めるべき。
+- `TicketOrchestrationPlanQuery` に blocker はない。
+- Risk は feature-api / tool-registry / ticket-tools だが、削除対象・非目標（Plugin/MCP permission policy を導入しない）が明記済み。
+- 他 queued work と主な変更面が異なるため並列開始可能。API cleanup の影響が大きい場合は Coder に escalation させる。
+
+Evidence checked:
+- Ticket body / thread / artifacts。
+- relation records: incoming dependency from `00001KTR81P9X` only。
+- orchestration plan records: なし。
+- bounded code context: `HostAuthority*` occurrences across `crates/pod` / feature registry / ticket/task feature tests。
+
+IntentPacket:
+- `pod::feature` public API から `HostAuthority`, `HostAuthorityRequest`, `HostAuthorityGrantSet` と related grant/install report semantics を削除し、ordinary contribution diagnostics に整理する。
+
+Binding decisions / invariants:
+- Renamed feature-layer authority/grant model は作らない。
+- Plugin permission policy / MCP trust policy はこの Ticket で実装しない。
+- Ticket tools は explicit TicketFeatureConfig / backend validation / access-level config を維持する。
+- Useful contribution checks（duplicate names、undeclared categories等）は残す。
+
+Validation:
+- Focused pod feature / ticket / task tests、`cargo fmt --check`、`cargo check --workspace --all-targets`、可能なら `nix build .#yoi`。

+## Implementation report
+
+Commit: `5549c50d8679` (`feat: remove feature host authority API`)
+
+Files changed:
+- `crates/pod/src/feature.rs`
+  - Removed `HostAuthority`, `HostAuthorityRequest`, `HostAuthorityGrantSet`, host-authority denial errors, grant plumbing, and per-tool host-authority gates from the public feature API/install path.
+  - Kept ordinary contribution declaration diagnostics: duplicate names, undeclared/mismatched tools, undeclared hooks/background tasks/services, skipped contributions, and service requirement diagnostics.
+  - Kept install reports focused on installed/skipped contributions and diagnostics without security grant semantics.
+- `crates/pod/src/feature/builtin/ticket.rs`
+  - Stopped declaring TicketBackend host authority and registering Ticket tools with feature-layer authority requirements.
+  - Preserved explicit `TicketFeatureConfig`, backend provider/root validation, and access-level-controlled tool exposure.
+- `crates/pod/src/feature/builtin/task/mod.rs`
+  - Removed Task feature prose that referenced feature-layer host authorities.
+
+Validation:
+- `cargo test -p pod feature:: --lib` — passed (46 tests).
+- `cargo test -p pod feature::builtin::task --lib` — passed (18 tests).
+- `cargo test -p ticket` — passed (68 tests + doc-tests).
+- `cargo fmt --check` — passed.
+- `cargo check --workspace --all-targets` — passed.
+- `git diff --check` — passed before commit.
+- Source grep under `crates/**/*.rs` found no remaining `HostAuthority*`, `host_authority`, `with_host_authority`, `requested_host_authorities`, or `required_host_authorities` symbols/terminology after cleanup.
+
+Residual risks / notes:
+- `nix build .#yoi` was not run; this change does not modify dependencies, `Cargo.lock`, packaging, or source filters.
+- Related Plugin/MCP planning Ticket review was not performed from this delegated Coder scope because only Ticket `00001KV0SP0TY` is readable/writable in `.yoi/tickets`; no Plugin/MCP permission or trust policy was implemented.

+
+## Review: approve
+
+Reviewed implementation commits `5549c50d` and `3faf7d7b` against Ticket `00001KV0SP0TY`.
+
+Evidence:
+- `crates/pod/src/feature.rs` removes the feature-layer `HostAuthority`, `HostAuthorityRequest`, `HostAuthorityGrantSet`, grant/denial/install-report semantics, and per-tool authority gates. The remaining feature API is contribution/lifecycle/diagnostic oriented: tools, hooks, background tasks, services, notifications, and install diagnostics.
+- No renamed equivalent authority/grant layer was introduced in `pod::feature`; remaining checks are ordinary contribution diagnostics such as duplicate tool names, undeclared tools/hooks/background tasks/services, service requirements, skipped contributions, and install errors.
+- `crates/pod/src/feature/builtin/ticket.rs` no longer requests or registers feature-layer host authority. Ticket tool exposure remains controlled by `TicketFeatureConfig` resolution, backend provider/root validation, and `TicketFeatureAccess` / base-orchestration tool selection. Missing/invalid backend roots and unsupported providers still fail closed without registering tools.
+- `crates/pod/src/feature/builtin/task/mod.rs` no longer describes task tools in host-authority terms; task hooks/tools still install through the normal feature registry path.
+- Source grep under `crates/**/*.rs` found no remaining `HostAuthority`, `HostAuthorityRequest`, `HostAuthorityGrantSet`, `host_authority`, `with_host_authority`, `requested_host_authorities`, or `required_host_authorities` symbols/terms.
+- Related Plugin/MCP planning Tickets inspected (`00001KTR81P9X`, `00001KTR82RB7`, `00001KSXRQ4G8`, `00001KT0Z4BK8`) state that Plugin/MCP permission/trust policy is not a `pod::feature` authority/grant dependency. The remaining mentions are negative boundary statements, not implementation reliance.
+
+Validation performed:
+- `git diff --check c4465a04..HEAD` — passed.
+- `cargo test -p pod feature:: --lib` — passed.
+- `cargo test -p pod feature::builtin::task --lib` — passed.
+- `cargo test -p ticket` — passed.
+- `cargo fmt --check` — passed.
+- `cargo check --workspace --all-targets` — passed.
+
+Not run:
+- `nix build .#yoi`; skipped because this review scope is source read-only with writes limited to `target/` and this Ticket record, and the change does not touch dependencies, `Cargo.lock`, packaging, or source filters.
+
+Risks / notes:
+- This intentionally removes the feature-layer authority gate rather than replacing it. Any future Plugin/MCP permission policy must be implemented in its owning layer and must not reintroduce this as a feature-layer grant API.
+
+Decision: approved.

+Implementation report for Ticket 00001KV0TJVN5
+
+Files changed:
+- `tests/e2e/src/lib.rs`
+  - Added a cached e2e binary provider using `OnceLock`.
+  - Preserves `YOI_E2E_BIN=<path>` as the explicit override and skips the default cargo build provider in that path.
+  - Default path runs `${CARGO:-cargo} build -p yoi --features e2e-test --bin yoi` from the workspace root, then returns the direct `target/{profile}/yoi` binary path for PTY spawning.
+  - Writes `target/e2e-artifacts/binary-provider.json` and emits diagnostics with provider, build command, binary path, and tested-subprocess env policy.
+  - Expanded command-failure diagnostics to include command args.
+  - Follow-up: isolated tested `yoi` subprocess environments in both `PanelHarness::spawn` and fixture setup `run_yoi_capture` with `env_clear()` plus explicit allowlists only.
+  - Follow-up: recorded env policy in `run.json`, `binary-provider.json`, and per-fixture `fixture-commands.jsonl` artifacts.
+  - Follow-up: added a regression assertion that tested-subprocess policies use `env_clear`, do not allow `PATH`, and default-deny provider credentials (`OPENAI_API_KEY`, `ANTHROPIC_API_KEY`, `GEMINI_API_KEY`) and secret-like patterns.
+  - Follow-up: relative `YOI_E2E_BIN` values are resolved against the workspace root and must exist, so tested subprocess launch does not rely on `PATH` lookup.
+- `tests/e2e/tests/panel.rs`
+  - Updated panel tests to use the fallible cached binary provider.
+
+Env isolation policy:
+- Cargo build provider remains a build-tool command and is not treated as the tested `yoi` subprocess.
+- Tested `yoi` fixture setup commands receive only: `HOME`, `XDG_DATA_HOME`, `XDG_STATE_HOME`, `XDG_CONFIG_HOME`, `YOI_POD_RUNTIME_COMMAND`.
+- Tested `yoi panel` commands receive only: fixture `HOME`, `XDG_DATA_HOME`, `XDG_STATE_HOME`, `XDG_CONFIG_HOME`, `TERM`, `YOI_TUI_TEST_EVENTS`, `YOI_POD_RUNTIME_COMMAND`, and `YOI_TUI_TEST_HOLD_BACKGROUND_TASK` when used.
+- `PATH` is intentionally not passed to tested `yoi` subprocesses; the harness launches the already-resolved binary path directly.
+- Host provider credentials / token / secret-like environment variables are default-denied. Future provider/LLM E2E should use fixture providers, canned servers, or explicit test env instead of inheriting host credentials.
+
+Validation:
+- `cargo fmt --check` — passed.
+- `git diff --check` — passed.
+- `cargo check -p yoi-e2e --all-targets --features e2e` — passed.
+- `cargo test -p yoi-e2e --features e2e tested_yoi_env_policy_is_env_clear_allowlist -- --nocapture` — passed.
+- `unset YOI_E2E_BIN && OPENAI_API_KEY=host-secret ANTHROPIC_API_KEY=host-secret GEMINI_API_KEY=host-secret cargo test -p yoi-e2e --features e2e --test panel -- --nocapture` — passed; default provider built the current `yoi` binary and tested `yoi` subprocesses used isolated env policy artifacts. Host provider env was present for the harness but is not inherited by tested `yoi` subprocesses because `env_clear()` is applied before the allowlist.
+- `YOI_E2E_BIN=/home/hare/Projects/yoi/.worktree/e2e-binary-provider/target/debug/yoi OPENAI_API_KEY=host-secret ANTHROPIC_API_KEY=host-secret GEMINI_API_KEY=host-secret cargo test -p yoi-e2e --features e2e --test panel -- --nocapture` — passed; override provider path used without invoking the default cargo-build provider, and tested `yoi` subprocesses still used isolated env policy.

+- None known.

+## Review: approve
+
+Decision: approve for Ticket `00001KV0TJVN5`.
+
+Evidence reviewed:
+- Ticket intent/acceptance criteria require default E2E setup to build `yoi` with `cargo build -p yoi --features e2e-test --bin yoi`, then direct-spawn the produced binary, while preserving `YOI_E2E_BIN` override and existing panel E2E behavior.
+- `tests/e2e/src/lib.rs` now resolves `yoi_binary()` through a `OnceLock`-cached `BinaryProviderInfo`. The default path runs `${CARGO:-cargo} build -p yoi --features e2e-test --bin yoi` from the workspace root and returns `target/{debug|release}/yoi`; the override path validates and uses `YOI_E2E_BIN` without invoking the cargo-build provider.
+- PTY execution remains `Command::new(&config.binary).arg("panel")`; `cargo run` is not in the process-under-test path.
+- `PanelHarness::spawn` and fixture `run_yoi_capture` both call `env_clear()` and then set only explicit fixture/test variables. `PATH` and provider credentials are not allowlisted. `YOI_POD_RUNTIME_COMMAND` is set to the resolved binary path, so tested subprocesses do not need host `PATH`.
+- Diagnostics/artifacts include provider/build/env policy in `target/e2e-artifacts/binary-provider.json`, panel `run.json`, and fixture `fixture-commands.jsonl`.
+- Existing mouse-capture guard (`expect_mouse_capture_enabled` / SGR 1000+1006 tracking), background-task quit barrier assertions, and `e2e-test` production boundary code were not weakened by this diff.
+
+Validation:
+- Reviewer reran `git diff --check a4df9754..HEAD` — passed.
+- Reviewer reran `cargo test -p yoi-e2e --features e2e tested_yoi_env_policy_is_env_clear_allowlist -- --nocapture` — passed.
+- Also accepted Orchestrator-reported full validation, including fmt/check, `cargo check -p yoi-e2e --all-targets --features e2e`, default panel E2E with host provider env present, and `YOI_E2E_BIN` override panel E2E with host provider env present — all reported passed.
+
+Risks / follow-up:
+- No blocking issues found. The cargo build provider intentionally still uses build-tool environment; tested `yoi` subprocesses are isolated.

+## 背景
+
+`00001KSKBP9YG` の E2E harness first slice では `YOI_E2E_BIN` または推測された `target/debug/yoi` を process-under-test として使っていた。これだと任意タイミングの `cargo test -p yoi-e2e --features e2e ...` 実行時に、最新 source から build された `yoi` binary が使われる保証がない。
+
+ユーザー判断:
+- `cargo run` を process-under-test にするより、E2E harness が test setup で `cargo build -p yoi --features e2e-test --bin yoi` を実行し、生成された binary を直接 PTY spawn する方針で修正する。
+
+## 要件
+
+- `YOI_E2E_BIN` が明示されていない通常 E2E 実行では、harness が workspace root で `cargo build -p yoi --features e2e-test --bin yoi` を実行してから、生成された binary path を使う。
+- `cargo run` を PTY の process-under-test にしない。PTY / Ctrl+C / Quit latency 測定対象は `yoi` binary 本体にする。
+- `YOI_E2E_BIN` は明示 override として残してよい。
+- 複数 test で build が重複しすぎないよう、可能なら `OnceLock` 等で同一 test process 内 1 回に寄せる。
+- artifact / error message に binary provider / build command / binary path が分かる情報を残す。
+- 既存の production/non-production boundary、`e2e-test` feature gating、mouse capture tracking、quit pending barrier を壊さない。
+
+## 受け入れ条件
+
+- `cargo test -p yoi-e2e --features e2e --test panel -- --nocapture` だけで、事前の手動 `cargo build -p yoi --features e2e-test` なしに E2E が実行できる。
+- E2E 実行時に build された `target/debug/yoi` が PTY に直接 spawn される。
+- `YOI_E2E_BIN=<path>` 指定時は override としてその path が使われる。
+- 既存 Panel E2E 2 本が pass する。
+- `cargo fmt --check`、`git diff --check`、関連 package check が pass する。

+Reason:
+- ユーザーが方針を明示した: `cargo run` を PTY の process-under-test にせず、E2E harness が `cargo build -p yoi --features e2e-test --bin yoi` を実行し、生成された binary を直接 spawn する。
+- Ticket は `queued` で、要件・受け入れ条件は具体的。blocking relation はなく、既存 E2E harness の小さな follow-up として実装可能。
+- 既存 production/non-production boundary、mouse capture check、quit pending barrier は維持すべき invariant として明記済み。
+
+Evidence checked:
+- Ticket body / relation to `00001KSKBP9YG`。
+- Existing E2E harness code: `tests/e2e/src/lib.rs::yoi_binary()` currently prefers `YOI_E2E_BIN`, then infers `target/debug/yoi`, but does not build it。

+Binding decisions / invariants:
+- `cargo run` を process-under-test にしない。
+- `YOI_E2E_BIN` explicit override は残してよい。
+- default path は harness 内 `cargo build -p yoi --features e2e-test --bin yoi` + direct binary spawn。
+- production/non-production boundary と `e2e-test` feature gating を壊さない。
+- mouse capture tracking / quit pending barrier を壊さない。
+
+Requirements / acceptance criteria:
+- 事前 manual build なしに `cargo test -p yoi-e2e --features e2e --test panel -- --nocapture` が pass する。
+- `YOI_E2E_BIN=<path>` 指定時は override としてその path が使われる。
+- Build command / binary path が artifact または diagnostics から分かる。
+- `cargo fmt --check`、`git diff --check`、関連 checks が pass。
+
+Implementation latitude:
+- `OnceLock` 等で同一 test process 内の build を 1 回にまとめてよい。
+- Workspace root detection は `CARGO_MANIFEST_DIR` parent traversal、`cargo metadata`、または robust helper のいずれでもよい。
+- Cargo executable は `CARGO` env を尊重する。

+Escalate if:
+- workspace/package layout 上、E2E test process 内から cargo build するのが大きな cyclic/build-system 問題を起こす場合。
+- Nix/package source filter 等の追加変更が必要になる場合。

+
+## Decision
+
+追加の critical gap: E2E subprocess environment が host credentials を継承し得る。
+
+Current finding:
+- `PanelHarness::spawn` と fixture setup の `run_yoi_capture` は `Command::new(binary)` に対して `env_clear()` を呼んでいない。
+- `HOME` / `XDG_*` は fixture dir に差し替えているが、通常の process environment は継承される。
+- そのため、現時点の Panel tests は LLM call を意図的に起こしていないものの、何らかの E2E path が provider/LLM call に到達した場合、host の `OPENAI_API_KEY` / `ANTHROPIC_API_KEY` / その他 provider credentials や secret-related env を見てしまう可能性がある。
+
+Decision:
+- E2E harness は default で host environment を継承してはならない。
+- `Command` 起動時は `env_clear()` を使い、必要最小限の env（`HOME`, `XDG_*`, `TERM`, `PATH`/`CARGO` 等 build/runtime に必要なもの、`YOI_TUI_TEST_EVENTS`, `YOI_POD_RUNTIME_COMMAND`, explicit test env）だけを allowlist で渡す。
+- Provider credentials / secret refs / network credentials は default deny。LLM/provider E2E を将来追加する場合は fixture provider / canned server / explicit test-only env で渡す。
+- Panel/TUI E2E は real LLM call が発生しないことを前提にし、host auth への依存を禁止する。
+
+Acceptance addition for `00001KV0TJVN5`:
+- Existing subprocess launches (`PanelHarness::spawn`, `run_yoi_capture`, cargo build provider where appropriate) must not leak host provider credentials to the tested `yoi` process。
+- At minimum, yoi subprocess env should be allowlisted and provider key names should be absent unless explicitly supplied by a future fixture provider test。
+
+---
+
+<!-- event: decision author: orchestrator at: 2026-06-13T15:53:07Z -->
+
+## Decision
+
+Environment-boundary reference added: `docs/development/environment.md` is binding context for this follow-up.
+
+Relevant policy:
+- Environment variables are a minimized runtime boundary.
+- Provider credentials and runtime configuration should not depend on ambient process state.
+- Tests should prefer typed fixtures/injection and mutate process environment only around thin env-reader behavior.
+- `YOI_POD_RUNTIME_COMMAND` is a development-only executable-path override, not a general ambient configuration channel.
+
+Implication for this Ticket:
+- E2E harness must not let tested `yoi` subprocesses inherit host env by default.
+- `PanelHarness::spawn` and fixture setup commands should use `env_clear()` plus an explicit allowlist.
+- Provider/secret/network credential env must be absent unless a future provider-fixture E2E explicitly injects test-only values.
+- Existing `YOI_*` test env should be limited to the feature-gated E2E observability/binary runtime paths and documented as test-only/dev-only surface, not normal runtime configuration.
+- The cargo build provider should avoid putting Cargo itself in the measured PTY path; any build env inheritance must be considered separately from the tested `yoi` subprocess env boundary.

+Implementation report for Ticket 00001KV0TJVN5
+
+Files changed:
+- `tests/e2e/src/lib.rs`
+  - Added a cached e2e binary provider using `OnceLock`.
+  - Preserves `YOI_E2E_BIN=<path>` as the explicit override and skips the default cargo build provider in that path.
+  - Default path runs `${CARGO:-cargo} build -p yoi --features e2e-test --bin yoi` from the workspace root, then returns the direct `target/{profile}/yoi` binary path for PTY spawning.
+  - Writes `target/e2e-artifacts/binary-provider.json` and emits diagnostics with provider, build command, binary path, and tested-subprocess env policy.
+  - Expanded command-failure diagnostics to include command args.
+  - Follow-up: isolated tested `yoi` subprocess environments in both `PanelHarness::spawn` and fixture setup `run_yoi_capture` with `env_clear()` plus explicit allowlists only.
+  - Follow-up: recorded env policy in `run.json`, `binary-provider.json`, and per-fixture `fixture-commands.jsonl` artifacts.
+  - Follow-up: added a regression assertion that tested-subprocess policies use `env_clear`, do not allow `PATH`, and default-deny provider credentials (`OPENAI_API_KEY`, `ANTHROPIC_API_KEY`, `GEMINI_API_KEY`) and secret-like patterns.
+  - Follow-up: relative `YOI_E2E_BIN` values are resolved against the workspace root and must exist, so tested subprocess launch does not rely on `PATH` lookup.
+- `tests/e2e/tests/panel.rs`
+  - Updated panel tests to use the fallible cached binary provider.
+
+Env isolation policy:
+- Cargo build provider remains a build-tool command and is not treated as the tested `yoi` subprocess.
+- Tested `yoi` fixture setup commands receive only: `HOME`, `XDG_DATA_HOME`, `XDG_STATE_HOME`, `XDG_CONFIG_HOME`, `YOI_POD_RUNTIME_COMMAND`.
+- Tested `yoi panel` commands receive only: fixture `HOME`, `XDG_DATA_HOME`, `XDG_STATE_HOME`, `XDG_CONFIG_HOME`, `TERM`, `YOI_TUI_TEST_EVENTS`, `YOI_POD_RUNTIME_COMMAND`, and `YOI_TUI_TEST_HOLD_BACKGROUND_TASK` when used.
+- `PATH` is intentionally not passed to tested `yoi` subprocesses; the harness launches the already-resolved binary path directly.
+- Host provider credentials / token / secret-like environment variables are default-denied. Future provider/LLM E2E should use fixture providers, canned servers, or explicit test env instead of inheriting host credentials.
+
+Validation:
+- `cargo fmt --check` — passed.
+- `git diff --check` — passed.
+- `cargo check -p yoi-e2e --all-targets --features e2e` — passed.
+- `cargo test -p yoi-e2e --features e2e tested_yoi_env_policy_is_env_clear_allowlist -- --nocapture` — passed.
+- `unset YOI_E2E_BIN && OPENAI_API_KEY=host-secret ANTHROPIC_API_KEY=host-secret GEMINI_API_KEY=host-secret cargo test -p yoi-e2e --features e2e --test panel -- --nocapture` — passed; default provider built the current `yoi` binary and tested `yoi` subprocesses used isolated env policy artifacts. Host provider env was present for the harness but is not inherited by tested `yoi` subprocesses because `env_clear()` is applied before the allowlist.
+- `YOI_E2E_BIN=/home/hare/Projects/yoi/.worktree/e2e-binary-provider/target/debug/yoi OPENAI_API_KEY=host-secret ANTHROPIC_API_KEY=host-secret GEMINI_API_KEY=host-secret cargo test -p yoi-e2e --features e2e --test panel -- --nocapture` — passed; override provider path used without invoking the default cargo-build provider, and tested `yoi` subprocesses still used isolated env policy.

+
+## Review: approve
+
+## Review: approve
+
+Decision: approve for Ticket `00001KV0TJVN5`.
+
+Evidence reviewed:
+- Ticket intent/acceptance criteria require default E2E setup to build `yoi` with `cargo build -p yoi --features e2e-test --bin yoi`, then direct-spawn the produced binary, while preserving `YOI_E2E_BIN` override and existing panel E2E behavior.
+- `tests/e2e/src/lib.rs` now resolves `yoi_binary()` through a `OnceLock`-cached `BinaryProviderInfo`. The default path runs `${CARGO:-cargo} build -p yoi --features e2e-test --bin yoi` from the workspace root and returns `target/{debug|release}/yoi`; the override path validates and uses `YOI_E2E_BIN` without invoking the cargo-build provider.
+- PTY execution remains `Command::new(&config.binary).arg("panel")`; `cargo run` is not in the process-under-test path.
+- `PanelHarness::spawn` and fixture `run_yoi_capture` both call `env_clear()` and then set only explicit fixture/test variables. `PATH` and provider credentials are not allowlisted. `YOI_POD_RUNTIME_COMMAND` is set to the resolved binary path, so tested subprocesses do not need host `PATH`.
+- Diagnostics/artifacts include provider/build/env policy in `target/e2e-artifacts/binary-provider.json`, panel `run.json`, and fixture `fixture-commands.jsonl`.
+- Existing mouse-capture guard (`expect_mouse_capture_enabled` / SGR 1000+1006 tracking), background-task quit barrier assertions, and `e2e-test` production boundary code were not weakened by this diff.
+
+Validation:
+- Reviewer reran `git diff --check a4df9754..HEAD` — passed.
+- Reviewer reran `cargo test -p yoi-e2e --features e2e tested_yoi_env_policy_is_env_clear_allowlist -- --nocapture` — passed.
+- Also accepted Orchestrator-reported full validation, including fmt/check, `cargo check -p yoi-e2e --all-targets --features e2e`, default panel E2E with host provider env present, and `YOI_E2E_BIN` override panel E2E with host provider env present — all reported passed.
+
+Risks / follow-up:
+- No blocking issues found. The cargo build provider intentionally still uses build-tool environment; tested `yoi` subprocesses are isolated.

+## Implementation report
+
+Integration outcome: merged and validated.
+
+- Implementation branch: `ticket-00001KV0TJVN5-e2e-binary-provider`
+- Implementation commits: `13d00530 test: build e2e yoi binary provider`, `47efeb01 test: isolate e2e yoi subprocess env`
+- Review commit/event: `7e24a8df ticket: approve e2e binary provider`
+- Orchestrator merge commit: `8abc2b7f merge: e2e binary provider`
+
+Implemented:
+- Default E2E binary provider now runs `${CARGO:-cargo} build -p yoi --features e2e-test --bin yoi` from workspace root, caches the result, and direct-spawns the produced `target/{profile}/yoi` binary for PTY tests。
+- `YOI_E2E_BIN=<path>` remains an explicit override and skips the default cargo-build provider。
+- `cargo run` is not used as process-under-test; Cargo is not in the PTY/signal/quit-latency measured path。
+- Tested `yoi` subprocesses (`PanelHarness::spawn` and fixture setup `run_yoi_capture`) now use `env_clear()` plus explicit allowlists only。
+- Host provider credentials / token / secret-like env are default-denied for tested `yoi` subprocesses。
+- Artifacts include binary provider/build command/binary path and tested subprocess env policy。
+
+Orchestrator validation after merge:
+- `cargo fmt --check`: PASS

+
+Residual note:
+- Cargo build provider intentionally uses build-tool environment; only tested `yoi` subprocesses are env-isolated. Future LLM/provider E2E should use fixture providers/canned servers/explicit test env, not host credentials。
+
+Next:
+- Mark Ticket `done` and clean up child coder/reviewer Pods plus implementation worktree/branch. Closure remains separate。

+
+E2E binary provider follow-up was reviewed, approved, merged into the Orchestrator branch as `8abc2b7f`, and validated in the Orchestrator worktree. Default E2E runs now build the current `yoi` binary before direct PTY spawn, `YOI_E2E_BIN` override remains available, and tested `yoi` subprocesses are isolated with `env_clear()` plus allowlist so host provider credentials are not inherited.

+
+## Comment
+
+Post-merge concern from user: E2E isolation may still have leaked or left visible Pod/worktree artifacts.
+
+Observed concern:
+- User reports Pods named `yoi-orchestrator-orchestrator` and `workspace-orchestrator` appeared.
+
+Current assessment:
+- Earlier E2E runs before the env isolation follow-up inherited host environment, including likely `XDG_RUNTIME_DIR`, so `yoi panel` could observe the host/global runtime Pod registry under `/run/user/...` even though `HOME`/`XDG_DATA_HOME` were fixture paths。
+- The fixture also intentionally writes blocking Pod metadata for `workspace` and `workspace-orchestrator` under fixture `XDG_DATA_HOME` to drive panel rows. That should be fixture-local, but if runtime/data isolation is wrong it can become visible outside the intended fixture。
+- The later `env_clear()` + allowlist fix prevents host env credential leak and likely prevents inheriting `XDG_RUNTIME_DIR`, causing runtime fallback to fixture HOME; however, no explicit regression assertion currently proves that E2E cannot see/create global runtime Pod state or workspace-orchestrator worktrees。
+
+Required follow-up direction:
+- Add explicit runtime isolation to E2E (`XDG_RUNTIME_DIR` or equivalent controlled fixture runtime path, or an assertion that fallback runtime is fixture-local)。
+- Add regression assertions/artifacts proving tested `yoi panel` sees only fixture Pod metadata/runtime state and does not observe host live Pods。
+- Ensure E2E cleanup removes any fixture Pod metadata/runtime/worktree artifacts it creates。
+- Investigate and clean any residual `yoi-orchestrator-orchestrator` / `workspace-orchestrator` artifacts only after confirming whether they are live Pods, fixture artifacts, or prior Panel-created worktrees。

+---
+
+## Background
+
+`00001KTTHP8HE` で、Panel Orchestrator 起動時に dedicated orchestration worktree を作成・再利用する仕組みが導入された。
+
+現在の layout は概ね次の default 導出になっている。
+
+- path: `<workspace>/.worktree/orchestration/<workspace-orchestrator-pod-name>`
+- branch: `orchestration/<workspace-orchestrator-pod-name>`
+
+`yoi` workspace では `workspace_orchestrator_pod` が `yoi-orchestrator` のため、branch は `orchestration/yoi-orchestrator` になる。
+
+現状の Yoi では Ticket orchestration 設定の中心が `.yoi/ticket.config.toml` であり、ticket がほぼ orchestration の意味を持っているため、Panel Orchestrator 用 orchestration branch 名もこの設定ファイルで扱う。
+
+## Requirements
+
+- `.yoi/ticket.config.toml` で Panel Orchestrator の orchestration branch 名を指定できるようにする。
+- 設定が存在しない場合は既存挙動を維持する。
+  - default: `orchestration/<workspace-orchestrator-pod-name>`
+  - `yoi` では引き続き `orchestration/yoi-orchestrator`
+- 設定は typed Ticket config として扱い、Panel 専用の ad-hoc 読み取りや string literal の散在にしない。
+- Schema は次のような形を基本案とする。
+
+```toml
+[orchestration]
+branch = "orchestration/yoi-orchestrator"
+```
+
+- exact key name は既存 config model との整合性を見て実装時に調整してよいが、documented / tested な workspace config として扱う。
+- worktree 作成・復元・reuse validation・diagnostics が、すべて同じ resolved branch 名を使う。
+- hard-coded `orchestration/<stem>` は default 導出としてのみ残し、実際の lifecycle は resolved config value 経由にする。
+- invalid branch name は Git 操作前に拒否し、破壊的操作をしない。
+- configured branch が既存 orchestration worktree の branch と一致しない場合は、安全に診断する。
+  - 既存 worktree を勝手に checkout / reset / delete しない。
+  - 必要なら migration / remediation guidance を diagnostic に出す。
+- Panel diagnostics で、resolved orchestration branch が分かるようにする。
+- Queue / Orchestrator restore / launch context など、expected orchestration branch を前提にする経路がある場合は同じ設定を使う。
+
+## Acceptance criteria
+
+- `.yoi/ticket.config.toml` で orchestration branch 名を指定できる。
+- 設定なしの場合、既存 default branch 名が維持される。
+- custom branch 設定時、Panel Orchestrator の worktree create / reuse / restore validation が custom branch を使う。
+- invalid branch 設定では Git worktree 作成前に分かる error / diagnostic で止まる。
+- 既存 worktree が configured branch と異なる場合、破壊的 cleanup や silent checkout をせず、分かる diagnostic を返す。
+- Panel 表示または launch diagnostic から resolved branch 名を確認できる。
+- tests が追加・更新されている。
+  - default branch resolution
+  - configured branch resolution
+  - invalid branch rejection
+  - existing worktree branch mismatch diagnostic
+  - Panel orchestration worktree lifecycle が resolved branch を使うこと
+
+## Binding decisions / invariants
+
+- 設定ファイルは `.yoi/ticket.config.toml` とする。
+- 設定なしの既存挙動は維持する。
+- Git worktree / branch の安全境界は緩めない。
+- dirty / unknown / mismatched worktree を自動で修復・削除しない。
+- branch 名設定は Orchestrator の runtime workspace / Ticket backend root の安全性を変えない。
+- Ticket backend / role Profile / prompt context への hidden injection ではなく、明示的な workspace config として扱う。
+
+## Implementation latitude
+
+- exact config key name は、既存 config 構造との整合性を見て実装時に決めてよい。
+- branch validation は Git の refname validation または同等の安全な内部 validation を使ってよい。
+- worktree path も configured branch から derive すべきか、既存 path policy を維持するかは実装で判断してよい。ただし、branch config 変更時に既存 path と衝突する場合は安全な diagnostic を出すこと。
+- docs / sample config の更新範囲は、現在の config documentation 体系に合わせて最小限でよい。
+
+## Readiness
+
+- readiness: implementation_ready
+- risk_flags: [config-schema, git-worktree, panel-orchestration]
+- blocking open questions: なし
+
+## Escalation conditions
+
+- config schema の置き場所が `.yoi/ticket.config.toml` では不自然で、Profile / manifest / panel-local config との境界判断が必要になった場合。
+- branch 設定と worktree path 設定を分離しないと安全な migration path が作れない場合。
+- Queue handoff / Orchestrator restore が main workspace と orchestration worktree のどちらの config を読むべきか曖昧になった場合。
+- backward compatibility のために旧 branch/worktree を自動移行したくなる場合。自動移行は別判断にする。
+
+## Validation
+
+- `cargo test -p ticket config`
+- `cargo test -p tui orchestration --lib` または該当 targeted tests
+- `cargo fmt --check`
+- `git diff --check`
+- `target/debug/yoi ticket doctor`

+## Implementation report
+
+Implemented Ticket 00001KV0X254D.
+
+Files changed:
+- `crates/ticket/src/config.rs`
+  - Added typed `[orchestration] branch = "..."` config support via `TicketOrchestrationConfig` and validated `GitBranchName`.
+  - Kept default behavior as no configured branch; documented the optional config in the generated scaffold.
+  - Added config validation tests for valid custom branches and invalid Git branch names.
+- `crates/tui/src/multi_pod.rs`
+  - Resolved Panel Orchestrator worktree branch from typed ticket config, falling back to `orchestration/<workspace-orchestrator-pod-name>`.
+  - Reused the resolved branch for worktree creation, existing-worktree validation, restore preparation, queue handoff checks, and restore diagnostics.
+  - Preserved refusal behavior for dirty/unknown/mismatched worktrees; mismatches are diagnostic and do not checkout/delete/repair.
+  - Added TUI tests covering custom configured branch creation/reuse/restore, invalid branch rejection before worktree Git operations, and mismatched restore rejection without checkout.
+
+Validation:
+- `cargo test -p ticket config --lib` — passed.
+- `cargo test -p tui ensure_and_restore_use_configured_orchestration_branch --lib` — passed.
+- `cargo test -p tui invalid_configured_orchestration_branch_is_rejected_before_git_worktree_operations --lib` — passed.
+- `cargo test -p tui restore_rejects_mismatched_configured_orchestration_branch_without_checkout --lib` — passed.
+- `cargo fmt --check` — passed.
+- `git diff --check` — passed.
+- `cargo build -p yoi` — passed.
+- `target/debug/yoi ticket doctor` — passed.
+
+Additional note:
+- I also tried broader `cargo test -p tui orchestration --lib`; it compiled but includes the existing `multi_pod::tests::orchestrator_launch_context_uses_orchestration_root_for_runtime_workspace` failure, in code not touched by this change. The focused new orchestration-branch tests listed above pass.
+
+Commit:
+- `1c54689e tui: configure orchestration branch`
+
+Residual risks:
+- Branch validation is implemented as an internal Git-ref compatible validator rather than invoking `git check-ref-format`, so it is intentionally conservative (for example, rejects spaces and full `refs/...` names) before any worktree Git operation.

+
+<!-- event: review author: hare at: 2026-06-13T19:05:48Z status: approve -->
+
+## Review: approve
+
+Approve.
+
+Evidence:
+- `crates/ticket/src/config.rs` adds typed `[orchestration] branch = "..."` via `TicketOrchestrationConfig` and `GitBranchName`, with `deny_unknown_fields` preserved and scaffold documentation limited to the Ticket config surface. Missing config leaves `orchestration.branch_name() == None`, preserving the existing default.
+- `crates/tui/src/multi_pod.rs` resolves the Panel Orchestrator branch once through `resolved_orchestration_worktree_layout`, falling back to `orchestration/<workspace-orchestrator-pod-name>`, and uses that layout for create/reuse, restore preparation/validation/diagnostics, and Queue handoff preflight/sync notices.
+- Invalid configured branches fail during Ticket config loading / branch resolution before `.worktree` creation; existing dirty, unknown, wrong-branch, or unrelated-repo paths remain diagnostic-only and are not checked out, deleted, reset, or repaired.
+- No hidden prompt/Profile injection or unrelated config surface drift was found; the change stays in typed Ticket config plus Panel orchestration worktree handling.
+- Tests cover default resolution, configured branch creation/restore, invalid branch rejection before worktree operations, mismatched branch diagnostics without checkout, and Queue paths using the resolved branch.
+
+Validation performed:
+- `git diff --check c4465a04..HEAD` — passed.
+- `cargo fmt --check` — passed.
+- `cargo test -p ticket config --lib` — passed (23 tests).
+- `cargo test -p tui orchestration_worktree --lib` — passed (3 tests).
+- `cargo test -p tui configured_orchestration_branch --lib` — passed (3 tests).

+- `cargo test -p tui orchestration --lib` — failed only on the known unrelated `multi_pod::tests::orchestrator_launch_context_uses_orchestration_root_for_runtime_workspace` stale assertion; the branch/config-focused cases in that run passed.
+
+Residual risk:
+- Branch validation is an internal git-ref-compatible validator rather than an invocation of `git check-ref-format`; reviewed as acceptable and conservative for this Ticket.

+
+## 背景
+
+E2E harness は `00001KSKBP9YG` / `00001KV0TJVN5` で Panel PTY E2E、最新 `yoi` binary build、tested subprocess の env isolation を導入した。しかし、ユーザーから `yoi-orchestrator-orchestrator` / `workspace-orchestrator` などの Pod/worktree artifact が出現したとの報告があり、host runtime / Pod registry / worktree artifact isolation と cleanup がまだ十分に証明されていない。
+
+既知の問題:
+- 初期 E2E は `env_clear()` 前に `XDG_RUNTIME_DIR` など host env を継承し得た。
+- Fixture は `workspace` / `workspace-orchestrator` の Pod metadata を作るが、これは fixture-local でなければならない。
+- 現在の env isolation は host env leak を防ぐが、E2E が完全に clean な tmp runtime/data/workspace で動き、実行後に cleanup することを明示的に保証・検証していない。
+
+## 要件
+
+- E2E は毎回完全に clean な temporary environment を作って実行する。
+- Workspace / HOME / XDG_DATA_HOME / XDG_STATE_HOME / XDG_CONFIG_HOME / runtime dir / artifacts root を fixture ごとに分離する。
+- Tested `yoi` subprocess は host runtime / Pod registry / session / worktree / data dir を見ない。
+- Fixture で作る Pod metadata（例: `workspace`, `workspace-orchestrator`）は fixture-local であり、host/global registry に出ない。
+- 実行後、fixture runtime/data/workspace/temp dirs は成功・失敗に関係なく cleanup される。失敗時に必要な artifact は `target/e2e-artifacts/...` にコピーしてから cleanup する。
+- Cleanup policy / fixture root / runtime dir / data dir / removed paths を artifact に記録する。
+- 既存の binary provider、env credential isolation、mouse capture tracking、quit pending barrier を壊さない。
+
+## 受け入れ条件
+
+- `cargo test -p yoi-e2e --features e2e --test panel -- --nocapture` が clean tmp env を使い、終了後に fixture temp root を残さない。
+- E2E artifact から fixture workspace/data/runtime paths と cleanup result が確認できる。
+- Test または assertion により、Panel が host live Pods / host runtime registry を見ていないことを確認する。
+- Fixture-created `workspace-orchestrator` 等が fixture-local であり、cleanup 後に temp root ごと消えることを確認する。
+- Host `XDG_RUNTIME_DIR` などを設定した状態でも tested `yoi` は fixture runtime だけを見る。
+- `cargo fmt --check`、`git diff --check`、関連 `cargo check` / E2E tests が pass する。
+
+## 関連

+- `00001KSKBP9YG`: E2E harness first slice。
+- `00001KV0TJVN5`: E2E binary provider / env isolation follow-up。

+
+## Decision
+
+Routing decision: implementation_ready
+
+Reason:
+- ユーザーが E2E harness の clean tmp environment / cleanup を明示した。
+- Ticket は `queued` で、要件・受け入れ条件は具体的。既存 `00001KSKBP9YG` / `00001KV0TJVN5` の follow-up で、主な変更面は `tests/e2e` に bounded される。
+- Blocking relation はなく、既存 queued Tickets とは変更面が異なる。Orchestrator worktree は clean。
+- Risk は test/runtime isolation だが、binding invariants（host runtime registry 非参照、fixture-local Pod metadata、cleanup artifact 記録）が明確なため実装可能。
+
+Evidence checked:
+- 新規 Ticket body / related records。
+- `00001KV0TJVN5` の post-merge concern: host/global runtime registry を見た可能性、fixture `workspace-orchestrator` metadata、runtime isolation assertion 不足。
+- Existing E2E code map: `tests/e2e/src/lib.rs` の fixture setup / `PanelHarness::spawn` / `run_yoi_capture` / artifact handling。
+- Orchestrator workspace state: clean。
+
+IntentPacket:
+
+Intent:
+- E2E harness が毎回 clean な tmp workspace/data/runtime environment で実行され、host Pod/runtime registry を見ず、成功・失敗に関係なく fixture temp を cleanup するようにする。
+
+Binding decisions / invariants:
+- Tested `yoi` process は host runtime/data/session/worktree/Pod registry を見ない。
+- Fixture-created Pods (`workspace`, `workspace-orchestrator` 等) は fixture-local。
+- Failure diagnostics は `target/e2e-artifacts` にコピーして残し、fixture temp root は cleanup する。
+- Existing binary provider、env credential isolation、mouse capture guard、quit pending barrier を壊さない。
+- Root/original workspace では作業しない。
+
+Requirements / acceptance criteria:
+- `cargo test -p yoi-e2e --features e2e --test panel -- --nocapture` が clean tmp env を使い、終了後に fixture temp root を残さない。
+- Artifact に fixture workspace/data/runtime paths、cleanup result、env/runtime policy が残る。
+- Test/assertion で Panel が host live Pods / host runtime registry を見ないことを確認する。
+- Host `XDG_RUNTIME_DIR` 等が設定されていても tested `yoi` は fixture runtime だけを見る。
+- `cargo fmt --check` / `git diff --check` / relevant checks / E2E tests が pass。
+
+Implementation latitude:
+- `tempfile::TempDir` / custom guard / artifact snapshot strategy の具体設計は Coder が選んでよい。
+- Runtime dir は explicit `XDG_RUNTIME_DIR` fixture path でも、Yoi-specific fixture runtime env でもよいが、host fallback を使わないことを artifact/assertion で示す。
+- Failure artifact は fixture tree 全体ではなく必要 subset copy でよい。
+
+Escalate if:
+- Yoi runtime path discovery に explicit test runtime dir を渡す public/production surface 変更が必要になる場合。
+- Cleanup と artifact preservation が両立しない design constraint がある場合。

+
+## Implementation report
+
+Implemented scoped E2E tmp/runtime isolation for Ticket 00001KV0YK5S0.
+
+Files changed:
+- `tests/e2e/src/lib.rs`
+  - `FixtureWorkspace` now owns a `TempDir` under `target/e2e-tmp` and writes persistent scenario artifacts under `target/e2e-artifacts/<run-id>`.
+  - Each fixture creates isolated workspace, HOME, XDG data/state/config/runtime dirs and passes `XDG_RUNTIME_DIR` explicitly to all tested `yoi` subprocesses under `env_clear`.
+  - Fixture metadata records fixture root, workspace/home/XDG paths, runtime policy, env policy, and cleanup result.
+  - Cleanup snapshots the fixture tree into persistent artifacts, closes/removes the temp root, writes `cleanup.json`, and reports cleanup failure.
+- `tests/e2e/tests/panel.rs`
+  - Existing two Panel E2E tests now assert fixture path isolation, absence of host/runtime Pod marker leakage in rendered rows, and explicit fixture cleanup/removal after each scenario.
+
+Isolation/cleanup policy:
+- Tested `yoi` never inherits host env wholesale; fixture setup and Panel subprocesses use `env_clear` with an allowlist that includes only fixture HOME/XDG data/state/config/runtime plus test/runtime-specific variables.
+- `XDG_RUNTIME_DIR` is always a fixture-local runtime dir under the temporary fixture root.
+- Fixture-local Pod metadata markers (`workspace`, `workspace-orchestrator`) are created only inside fixture data home and panel rows assert no host/fixture runtime markers leak.
+- Artifacts persist outside the temp root in `target/e2e-artifacts`; cleanup snapshots selected fixture contents there before removing the temp root.
+
+Validation:
+- `cargo check -p yoi-e2e --all-targets --features e2e` — passed.
+- `cargo test -p yoi-e2e --features e2e --test panel -- --nocapture` — passed (2 tests).
+- `XDG_RUNTIME_DIR=/tmp/yoi-e2e-host-runtime-leak-test OPENAI_API_KEY=host-secret cargo test -p yoi-e2e --features e2e --test panel -- --nocapture` — passed (2 tests); artifacts show fixture `xdg_runtime_dir`, `host_xdg_runtime_dir_present: true`, and `cleanup_success: true`.
+- `YOI_E2E_BIN=target/debug/yoi cargo test -p yoi-e2e --features e2e --test panel -- --nocapture` — passed (2 tests).
+- `cargo fmt --check` — passed.
+- `git diff --check` — passed.
+
+Remaining gaps:
+- No known gaps within the delegated scope.

+
+## Review: approve
+
+外部 Reviewer Pod 起動を試みたが、この Orchestrator の現在の delegation scope では child launch validation が要求する root workspace read grant を再委譲できず、Reviewer Pod を起動できなかった。そのため Orchestrator が実装 diff・validation・artifact を直接確認した。
+
+確認した実装:
+- `tests/e2e/src/lib.rs` に per-scenario `FixtureWorkspace` / `TempDir` 管理を追加。
+- fixture root 配下に `workspace`、`home`、`data`、`state`、`config`、`runtime` を作り、tested `yoi` には `env_clear()` + fixture-local `XDG_RUNTIME_DIR` を渡す。
+- `PanelHarness::spawn` と fixture setup command は host `XDG_RUNTIME_DIR` / host provider env を継承しない。
+- fixture snapshot / cleanup report / fixture metadata を `target/e2e-artifacts/<run>/` に保存し、fixture temp root は cleanup 後に存在しないことを記録する。
+- tests は hostile host `XDG_RUNTIME_DIR` を設定した状態でも fixture runtime policy を使う。
+- existing binary provider、mouse capture guard、quit pending barrier、env credential isolation は維持されている。
+
+Validation performed by Orchestrator:
+- `cargo fmt --check`: PASS
+- `git diff --check`: PASS
+- `cargo check -p yoi-e2e --all-targets --features e2e`: PASS
+- `XDG_RUNTIME_DIR=/tmp/yoi-e2e-host-runtime-leak-test OPENAI_API_KEY=host-secret ANTHROPIC_API_KEY=host-secret GEMINI_API_KEY=host-secret cargo test -p yoi-e2e --features e2e --test panel -- --nocapture`: PASS
+- artifact spot-check: recent `cleanup.json` records `cleanup_success: true` and `fixture_root_exists_after: false`。
+- `target/e2e-tmp` の直下に residual fixture temp root が残っていないことを確認。
+
+Notes:
+- Failure artifact は fixture snapshot を保存するため、host への leak ではなく `target/e2e-artifacts` に診断情報が残る。
+- Fixture-created `workspace` / `workspace-orchestrator` Pod metadata は fixture data dir / snapshot に閉じる。host runtime/data registry を読む経路は fixture `XDG_RUNTIME_DIR` + env clear により遮断されている。
+
+Decision: approve.

+Integration outcome: merged and validated.
+
+- Implementation branch: `ticket-00001KV0YK5S0-e2e-tmp-isolation`
+- Implementation commit: `07e754ce test: isolate e2e tmp runtime fixtures`
+- Review: Orchestrator direct review `approve`（Reviewer Pod は現 delegated scope の child launch validation 制約で起動できなかったため、Orchestrator が diff / validation / artifact を確認）
+- Orchestrator merge commit: `20184eeb merge: e2e tmp isolation`
+
+Implemented:
+- E2E fixture now creates per-scenario clean temp root under `target/e2e-tmp` with isolated workspace, HOME, XDG data/state/config, and explicit fixture `XDG_RUNTIME_DIR`。
+- Tested `yoi` subprocesses continue to use `env_clear()` and now receive fixture-local runtime dir, preventing host runtime / Pod registry observation。
+- Fixture metadata, run metadata, fixture snapshot, and cleanup report are persisted under `target/e2e-artifacts/<run>` before temp cleanup。
+- Fixture temp roots are removed after scenario completion, and cleanup reports record `cleanup_success` plus `fixture_root_exists_after`。
+- Existing binary provider, `YOI_E2E_BIN` override, credential env isolation, mouse capture guard, and quit pending barrier remain intact。
+
+Orchestrator validation after merge:
+- `cargo fmt --check`: PASS
+- `git diff --check`: PASS
+- `cargo check -p yoi-e2e --all-targets --features e2e`: PASS
+- `XDG_RUNTIME_DIR=/tmp/yoi-e2e-host-runtime-leak-test OPENAI_API_KEY=host-secret ANTHROPIC_API_KEY=host-secret GEMINI_API_KEY=host-secret cargo test -p yoi-e2e --features e2e --test panel -- --nocapture`: PASS（2 tests）
+- Artifact spot-check: latest `cleanup.json` files record `cleanup_success: true` and `fixture_root_exists_after: false`。
+- `target/e2e-tmp` direct child count after validation: 0。
+
+Residual notes:
+- Persistent diagnostic artifacts intentionally remain under `target/e2e-artifacts`。
+- Fixture snapshots may contain fixture-local `workspace` / `workspace-orchestrator` metadata, but those live under the copied artifact snapshot, not host runtime/data state。
+
+Next:
+- Mark Ticket `done` and clean up implementation worktree/branch.

+
+## Background
+
+Before starting the `pod::feature` / MCP work, finish a small but useful real-process E2E safety net. This is **not** a request to build a broad E2E matrix. The goal is to cover the product-critical TUI paths and the regressions that recently escaped focused unit/integration tests.
+
+Relevant completed / in-flight history from git log:
+
+- `00001KSKBP9YG` / `96561897` / `10a1c383` / `bdc735b8`: opt-in PTY Panel E2E harness exists under `tests/e2e`.
+- `00001KV0TJVN5` / `13d00530` / `47efeb01` / `7fe463af`: E2E builds the current `yoi` binary by default and isolates tested subprocess env/provider credentials.
+- `00001KV0YK5S0` / `07e754ce` / `20184eeb` / `6aa7c650`: orchestration branch adds fixture-local tmp workspace/data/runtime isolation and cleanup. If not already merged into the implementation base, incorporate or depend on that work rather than reimplementing it.
+- `00001KV0723PC` / `cfe411e5`: late Panel quit latency was fixed; current E2E already has `panel_ctrl_c_exits_promptly_after_background_barrier` and should preserve/strengthen it.
+- `00001KV072V89` / `452c9df1`: Panel mouse click selection was implemented; current E2E already has `panel_mouse_click_selects_row_without_dispatching_action` and should preserve/strengthen it.
+- `00001KV04NJ8D` / `949ceb5a`: rewind live refresh was fixed, but it does not yet have a real-process PTY regression test.
+
+## Requirements
+
+- Keep E2E opt-in.
+  - Tests remain under `tests/e2e` and behind the existing `e2e` feature gate.
+  - `cargo test --workspace` must not run these tests by default.
+- Do not duplicate already-covered Panel cases.
+  - Preserve the existing late-quit-latency E2E.
+  - Preserve the existing mouse click-to-select E2E.
+  - If the tmp runtime isolation branch is not in the implementation base, merge/incorporate it first or make this Ticket depend on it.
+- Add only the missing critical-path coverage needed before larger feature/MCP work.
+  - A minimal Panel critical path must continue to cover startup, fixture row rendering/selection, and normal quit.
+  - Add a minimal single-Pod/TUI critical path only as needed to support rewind coverage; do not add real provider/network calls.
+- Strengthen late quit latency E2E only where useful.
+  - Keep the held-background-task / observable barrier approach.
+  - Assert user quit is observed and process exit remains within the bounded threshold.
+  - Avoid arbitrary sleeps when an observable event/barrier exists.
+- Strengthen mouse E2E for the currently missing behavior.
+  - Keep click-to-select without action dispatch.
+  - Add wheel input coverage for the viewport/row list behavior that was regressed by disabling mouse capture.
+  - Ensure the test/harness can detect reintroducing full drag-motion capture (`?1002h` / `?1003h`) where feasible from PTY output.
+  - Rename harness wording if needed: the current implementation enables normal mouse tracking for wheel/click, not full capture.
+- Add rewind UI E2E.
+  - Drive a real single-Pod TUI or equivalent PTY surface with fixture history/canned state.
+  - `Ctrl+R` opens the rewind picker.
+  - Selecting a rewind target with `Enter` causes the live TUI view/composer/state to update without requiring `Esc`, restart, or restore.
+  - Repeated `Enter` while a rewind is pending does not send multiple destructive rewind requests or produce delayed duplicate success notices.
+- Keep tests deterministic and content-safe.
+  - No real provider credentials.
+  - No network-backed LLM calls.
+  - Use fixtures, canned sessions, test-only provider/runtime controls, or other existing test hooks when needed.
+  - Do not leak host secret-like environment variables into tested processes.
+
+## Acceptance criteria
+
+- The focused E2E command, e.g. `cargo test -p yoi-e2e --features e2e --test panel -- --nocapture` plus any new E2E test target, runs from a clean checkout after building the current `yoi` binary automatically.
+- The current Panel smoke/click/quit tests still pass on the fixture-isolated harness.
+- If fixture runtime isolation is part of this implementation base, after a passing run no test Pod/socket appears in the user's real `~/.yoi` or `/run/user/<uid>/yoi`.
+- Late quit latency remains covered by an E2E that fails if quit waits for held background work past the configured threshold.
+- Mouse E2E fails if click-to-select dispatches an action, if wheel input is ignored, or if full drag-motion mouse capture is reintroduced where the harness can observe it.
+- Rewind UI E2E fails if rewind success only becomes visible after `Esc`, TUI restart, or Pod restore.
+- Failure artifacts include enough PTY output/events/status information to debug timing and UI failures.
+- Existing non-E2E tests remain unaffected by the opt-in E2E feature gate.
+- Validation includes focused E2E commands, affected crate tests/checks, `cargo build -p yoi`, and `nix build .#yoi`.
+
+## Non-goals
+
+- Full provider/API matrix E2E.
+- Real network-backed LLM calls.
+- CI-default enablement of E2E.
+- Exhaustive Ticket orchestration multi-agent workflow E2E.
+- Plugin/MCP E2E coverage.
+- Replacing focused unit/integration tests; this Ticket adds a small real-process safety net.

+## Decision
+
+修正:
+- 初回作成時は git log の確認が不足しており、既存/別 branch の E2E 実装済み範囲を一部重複して書いていた。
+- git log を確認し、既存の Panel E2E harness、latest-binary build、late quit latency E2E、mouse click selection E2E、orchestration branch の tmp runtime/data isolation を前提として反映した。
+- この Ticket は残差に絞る: wheel regression、rewind UI real-process regression、必要最小限の critical path 維持/補強。

+<!-- event: decision author: orchestrator at: 2026-06-13T17:51:56Z -->
+
+## Decision
+
+Routing decision: implementation_ready
+
+Reason:
+- Ticket は `queued` で、既存 E2E harness first slice / latest-binary build / env isolation / tmp runtime isolation を前提にした残差 coverage が具体化されている。
+- `TicketRelationQuery` の relation は `related` のみで、blocking dependency はない。`TicketOrchestrationPlanQuery` に既存 blocker/conflict 記録はない。
+- `00001KV0YK5S0` の tmp runtime/data isolation は Orchestrator branch に merge/validated 済みで、この Ticket の前提は満たされている。
+- Risk flags は `e2e` / `tui` / `pty` / `quit-latency` / `mouse-input` / `rewind` だが、binding scope は opt-in E2E の missing critical-path coverage に限定され、real provider/network call 禁止、host credential isolation、fixture runtime isolation などの invariants が明記されている。
+- Orchestrator worktree は clean。visible implementation Pods はない。ほか queued Ticket はあるが、Panel/TUI 変更面や broad authority model 変更と同時に進めると review/validation capacity と merge conflict risk が上がるため、この Ticket を先に受理し、他 queued は現時点で開始しない。
+
+Evidence checked:
+- Ticket body / thread / artifacts。
+- relation records: related links only。
+- orchestration plan records: なし。
+- related completed work: `00001KSKBP9YG`, `00001KV0TJVN5`, `00001KV0YK5S0`, `00001KV04NJ8D`, `00001KV0723PC`, `00001KV072V89`。
+- workspace state: Orchestrator worktree clean、live spawned implementation Pods なし。
+- current queue: `00001KV0X254D`, `00001KV09X0XC`, `00001KV0SP0TY`, `00001KV10SN02`。
+
+IntentPacket:
+
+Intent:
+- Existing opt-in `yoi-e2e` Panel PTY harness を土台に、larger feature/MCP work 前の remaining critical-path gaps を最小限埋める。
+- 既存 Panel quit latency / mouse click selection / tmp isolation coverage は維持し、wheel/drag-capture regression と rewind UI real-process regression を追加する。
+
+Binding decisions / invariants:
+- E2E は opt-in のまま。`cargo test --workspace` default に混ぜない。
+- No real provider credentials / no network-backed LLM calls。
+- Tested processes は clean fixture tmp workspace/data/runtime/env isolation を使い、host runtime/credential を見ない。
+- Existing binary provider and `YOI_E2E_BIN` override, env isolation, mouse capture guard, quit pending barrier, cleanup artifacts を壊さない。
+- `cargo run` を measured process-under-test にしない。
+- Full drag-motion mouse capture (`?1002h` / `?1003h`) を reintroduce しないことを可能な範囲で PTY output から確認する。
+- Rewind E2E は success が `Esc` / restart / restore 後でないと見えない状態を fail させる。
+
+Requirements / acceptance criteria:
+- Existing Panel smoke/click/quit tests still pass on fixture-isolated harness。
+- Mouse E2E covers wheel input for viewport/list behavior and fails if wheel is ignored where observable。
+- Mouse E2E fails if click-to-select dispatches action or if full drag-motion capture is observed where forbidden。
+- Rewind UI E2E drives real single-Pod TUI or equivalent PTY surface with fixture/canned state: `Ctrl+R` opens picker; target `Enter` updates visible live view/composer/state without requiring `Esc`, restart, or restore; repeated `Enter` while pending does not send duplicate destructive rewind requests。
+- Failure artifacts include PTY output/events/status/timing enough for diagnosis。
+- Validation includes focused E2E commands, affected checks/tests, `cargo build -p yoi`, and `nix build .#yoi`。
+
+Implementation latitude:
+- Coder may extend the existing PanelHarness or add a SinglePodHarness if cleaner。
+- Canned session/test-only runtime controls may be used, but must remain opt-in/read-only or test-only and must not enable real provider calls。
+- Wheel coverage may use structured events and/or screen artifact assertions, but must exercise PTY input path。
+- Rewind scenario can be minimal and fixture-driven; do not broaden into a full provider/protocol E2E matrix。
+
+Escalate if:
+- Rewind E2E requires broad public protocol/API changes or real provider calls。
+- Single-Pod PTY fixture cannot be built without exposing test-only production surfaces beyond the existing `e2e-test` boundary。
+- `nix build .#yoi` requires package/source-filter changes outside delegated scope。
+
+Validation:
+- `cargo test -p yoi-e2e --features e2e ...` focused targets。
+- `cargo fmt --check`。
+- `git diff --check`。
+- Relevant package checks/tests, including `cargo build -p yoi`。
+- `nix build .#yoi` because package/source-filter correctness may be affected by E2E/test files or Cargo changes。

+Implementation handoff blocked after acceptance.
+
+- Routing / IntentPacket / accepted plan は記録済み。
+- State は `queued -> inprogress` acceptance 済み。
+- Implementation worktree は作成済み: `/home/hare/Projects/yoi/.worktree/e2e-critical-path`
+- Branch: `ticket-00001KV10SN02-e2e-critical-path`
+
+Blocker:
+- Coder Pod `coder-00001KV10SN02-e2e-critical` の spawn に失敗した。
+- Child launch validation が runtime workspace root `/home/hare/Projects/yoi` の readable grant を要求したが、現在の Orchestrator delegation scope では `/home/hare/Projects/yoi` non-recursive read を子に再委譲できない。
+- Error: `failed to create spawned pod: cwd is not readable under the configured scope: /home/hare/Projects/yoi`
+
+Impact:
+- まだ Coder は起動しておらず、実装変更は行われていない。
+- Worktree creation だけが side effect として存在する。
+
+Next recovery options:
+1. Orchestrator Pod を、child launch validation に必要な root workspace non-recursive read delegation を持つ状態で再起動/復旧してから Coder を起動する。
+2. 明示許可があれば、この Orchestrator が sibling Coder なしで直接実装する。ただし本 Ticket は E2E/TUI/rewind の critical-path coverage で review 重要度が高いため、可能なら sibling Coder/Reviewer flow を復旧する方が望ましい。
+3. 継続できない場合は、作成済み worktree/branch を cleanup し、scope blocker を記録したまま人間判断待ちにする。
+
+No further implementation side effects were performed after the failed spawn.

+
+Coder Pod `coder-00001KV10SN02-e2e-critical` has been started after SpawnPod retry with explicit root non-recursive read grant. This records the missing acceptance marker before further implementation/review side effects continue; previous handoff report already documented the retry and scope.

+## Implementation report
+
+Implementation blocked / stopped for now.
+
+Problem:
+- Coder Pod `coder-00001KV10SN02-e2e-critical` is in an inconsistent communication state: `ReadPodOutput` reports it as stopped/unreachable, while restore/list surfaces report the socket as live/reachable, and `SendToPod` times out waiting for initial Snapshot.
+- Worktree `/home/hare/Projects/yoi/.worktree/e2e-critical-path` contains uncommitted changes in `crates/tui/src/multi_pod.rs`, `crates/tui/src/single_pod.rs`, `tests/e2e/src/lib.rs`, `tests/e2e/tests/panel.rs`, and new `tests/e2e/tests/rewind.rs`.
+- No Coder final report, commit, or Ticket implementation_report was received.
+
+Decision:
+- Per user instruction, stop this Ticket instead of attempting to merge incomplete/unreviewed work.
+- Do not merge this branch.
+- Preserve the dirty worktree for human/next-Orchestrator inspection rather than deleting it.
+
+Recovery needed:
+- Inspect dirty diff in `/home/hare/Projects/yoi/.worktree/e2e-critical-path`.
+- Decide whether to salvage/commit after validation, ask Coder to continue after runtime recovery, or discard and restart from clean branch.
+- Do not mark done until implementation is committed, reviewed, and validated.

+
+<!-- event: implementation_report author: orchestrator at: 2026-06-14T05:13:26Z -->
+
+## Implementation report
+
+Recovery action: hand off dirty worktree to a replacement Coder.
+
+User requested continuing with a different Coder after the prior Coder Pod stopped unexpectedly.
+
+Current worktree state before handoff:
+- Worktree: `/home/hare/Projects/yoi/.worktree/e2e-critical-path`
+- Branch: `ticket-00001KV10SN02-e2e-critical-path`
+- Dirty files from prior Coder attempt:
+  - `crates/tui/src/multi_pod.rs`
+  - `crates/tui/src/single_pod.rs`
+  - `tests/e2e/src/lib.rs`
+  - `tests/e2e/tests/panel.rs`
+  - `tests/e2e/tests/rewind.rs` (new)
+- `git diff --check` currently reports no whitespace/check errors.
+
+Replacement Coder task:
+- Inspect the dirty diff, decide whether it is salvageable, then either finish/commit/report it or stop with a concrete blocker.
+- Do not merge or clean up; Orchestrator will handle review/merge.

+## Implementation report
+
+Implemented critical-path TUI E2E coverage in commit b9f49eee.
+
+Files changed:
+- crates/tui/src/multi_pod.rs: panel mouse wheel events now move selection and emit e2e observer diagnostics without enabling full drag-motion capture.
+- crates/tui/src/single_pod.rs: e2e-test-only canned single-Pod rewind fixture path for real TUI/PTTY driving; preserves production/non-production boundary.
+- tests/e2e/Cargo.toml: disables auto-discovered integration tests and registers panel/rewind only behind the e2e feature.
+- tests/e2e/src/lib.rs: harness support for rewind fixture env isolation, wheel input, event waiting, and forbidden ?1002h/?1003h capture detection.
+- tests/e2e/tests/panel.rs: adds PTY wheel regression coverage and drag-capture failure assertion while keeping existing panel cases.
+- tests/e2e/tests/rewind.rs: adds single-Pod rewind picker/apply/duplicate-Enter regression.
+
+Validation:
+- cargo fmt --check
+- git diff --check
+- cargo test -p yoi-e2e --no-run
+- cargo build -p yoi
+- cargo test -p yoi-e2e --features e2e
+- cargo test -p tui --lib single_pod::tests::rewind
+- cargo test -p tui --lib mouse
+- nix build .#yoi
+
+Additional note:
+- Full cargo test -p tui was also attempted and failed in pre-existing/unrelated tests: multi_pod::tests::orchestrator_launch_context_uses_orchestration_root_for_runtime_workspace and spawn::tests::{profile_choices_include_builtin_and_project_default_marker, profile_choices_use_project_registry_default}. Focused changed-area tui tests passed.
+
+Residual risks:
+- Rewind E2E uses an e2e-test-only canned in-process fixture instead of a provider/socket-backed Pod, intentionally avoiding credentials/network while still exercising the real single-Pod TUI/PTTY path.
+- nix build emitted the expected dirty-tree warning before succeeding.

+
+<!-- event: review author: hare at: 2026-06-14T05:33:43Z status: approve -->
+
+## Review: approve
+
+APPROVE.
+
+Review evidence:
+- Diff base: inspected `git diff orchestration/yoi-orchestrator..HEAD`; changed files are limited to this Ticket record plus intended TUI/E2E files (`crates/tui/src/{multi_pod.rs,single_pod.rs}`, `tests/e2e/{Cargo.toml,src/lib.rs,tests/panel.rs,tests/rewind.rs}`). No unrelated Ticket records or broad code churn were present.
+- Existing Panel E2E remains opt-in: `tests/e2e/Cargo.toml` uses `autotests = false`; `panel` and `rewind` integration tests have `required-features = ["e2e"]`. `cargo test -p yoi-e2e --no-run` compiled only the library test, while `cargo test -p yoi-e2e --features e2e` ran the isolated panel/rewind cases.
+- Wheel PTY coverage is meaningful: the panel test drives real PTY SGR wheel input at a row coordinate derived from `rows_rendered`, then observes `mouse_wheel`, `selection_changed`, and refreshed `rows_rendered` events. This exercises terminal input delivery and row/list selection behavior rather than direct state mutation.
+- Mouse capture assertions cover the intended invariant: the TUI now enables normal tracking + SGR through the local `EnableWheelMouseCapture` command, and tests assert mouse capture is enabled while rejecting forbidden full drag-motion modes. Observed PTY artifacts from the reviewer run contained `?1000h`/`?1006h` once and `?1002h`/`?1003h` zero times for panel and rewind runs.
+- Rewind E2E uses a real single-Pod TUI/PTTY surface with an `e2e-test`-only fixture. The test sends `Ctrl+R`, `Enter`, and repeated `Enter`; observed events show picker open, exactly one rewind submit, duplicate Enter suppression while pending, and `rewind_applied` with restored composer text. The PTY output artifact also contained the restored text (`revise the plan`), so this covers visible composer restoration without Esc/restart/restore.
+- Credential/network isolation is preserved: the E2E harness uses `env_clear`, fixture HOME/XDG runtime/data/config/state, explicit runtime binary override, and default-deny provider credential policy. The rewind fixture is only compiled/activated behind the `e2e-test` feature and `YOI_TUI_TEST_REWIND_FIXTURE`; normal `cargo build -p yoi` passed without that fixture.
+
+Validation performed:
+- `cargo fmt --check` — pass
+- `git diff --check orchestration/yoi-orchestrator..HEAD` — pass
+- `cargo test -p yoi-e2e --no-run` — pass
+- `cargo build -p yoi` — pass
+- `cargo test -p yoi-e2e --features e2e` — pass (1 lib env-policy test, 3 panel tests, 1 rewind test)
+- `cargo test -p tui --lib single_pod::tests::rewind` — pass (5 tests)
+- `cargo test -p tui --lib mouse` — pass (4 tests)
+- `cargo test -p tui --lib` — fails in known unrelated tests already noted by implementation report: `multi_pod::tests::orchestrator_launch_context_uses_orchestration_root_for_runtime_workspace` and `spawn::tests::{profile_choices_include_builtin_and_project_default_marker, profile_choices_use_project_registry_default}`; 327 other tests passed, including the changed-area mouse/rewind tests.
+- `nix build .#yoi` — not run by reviewer because this review grant allows writes only under `target/` and this Ticket record; a normal nix build would write outside that boundary (store/result link). Coder's implementation report recorded a successful nix build with the expected dirty-tree warning.
+
+Residual risk:
+- The rewind E2E intentionally uses an in-process canned rewind fixture instead of a provider/socket-backed Pod to avoid credentials and network. This is acceptable for the Ticket's critical TUI/PTTY regression focus, but it is not full provider integration coverage.
+
+<!-- event: implementation_report author: orchestrator at: 2026-06-14T05:38:52Z -->

+Reviewer result:
+- `approve`。Panel wheel PTY coverage, forbidden drag-capture checks, single-Pod rewind PTY E2E with canned e2e-test fixture, no real provider/network calls, and existing tmp/env/runtime isolation preservation were reviewed.

+- `cargo test -p tui --lib mouse`: PASS
+- `nix build .#yoi`: PASS
+
+Residual notes:
+- Full `cargo test -p tui --lib` was not used as merge gate because reviewer/coder both observed known unrelated failures in `multi_pod::tests::orchestrator_launch_context_uses_orchestration_root_for_runtime_workspace` and `spawn::tests::{profile_choices_include_builtin_and_project_default_marker, profile_choices_use_project_registry_default}`.
+- Rewind E2E intentionally uses e2e-test-only canned fixture rather than provider/socket-backed Pod to avoid credentials/network while covering the TUI/PTTY regression path.
+
+Next:
+- Mark Ticket done and clean up replacement Coder / Reviewer Pods plus implementation worktree/branch.

+Commit:
+- implementation: `21bf009a3f95978007468005982903c8d7cae9e7` (`feat: move profile scope to launch policy`)

+- `crates/pod/src/entrypoint.rs`
+- `crates/pod/src/spawn/tool.rs`
+
+実装内容:
+- Builtin reusable Profiles から concrete filesystem `scope` / `delegation_scope` を削除した。
+- Profile resolution の implicit default workspace-write scope を廃止し、Profiles without scope を empty scope として解決可能にした。
+- Fresh profile launch の effective authority を `pod` entrypoint の launch policy で付与するようにした。
+  - normal Companion/TUI/default profile launch: workspace write direct scope（`.worktree` write deny）+ workspace read / `.worktree` write delegation。
+  - Ticket Orchestrator role launch: original workspace read direct scope + original workspace read / `<workspace>/.worktree` write delegation。root workspace write delegation は付与しない。
+  - Ticket Intake/Reviewer role launch: workspace read direct scope。
+  - Ticket Coder role launch: workspace write direct scope。
+- Single-file `--manifest` mode は従来どおり concrete `scope.allow` を要求し、Profile launch policy と混同しないようにした。
+- SpawnPod child scope replacement path は維持し、narrow Orchestrator delegation で Coder/Reviewer 用の root-read + implementation-worktree-write validation が成立することをテストした。
+- Existing user Profile `scope` / `delegation_scope` compatibility は deprecated-compatible path として残した（Ticket の選択肢に沿って、builtin role launch authority は Profile scope に依存しない）。
+
+Validation:
+- `cargo test -p manifest` ✅

+- `cargo build -p yoi` ✅
+- `cargo fmt --check` ✅
+- `git diff --check` ✅
+- `nix build .#yoi` not run: no Cargo.lock, packaging, or resource inclusion pattern changed.
+
+Residual risks / notes:

+Approve implementation review for Ticket 00001KV11DHGZ.
+
+Scope reviewed: implementation commit 21bf009a plus ticket report commit 77892b94 against base cdb12af9.
+
+Evidence:
+- Builtin role profile resources no longer contain `scope` or `delegation_scope`; reusable profile data retains role/model/prompt/feature/tool policy only.
+- Fresh profile launch scope is applied in `crates/pod/src/entrypoint.rs` by launch policy after profile resolution. Default/Companion launches receive direct workspace write scope with `.worktree` write denied and delegation gets workspace read plus `.worktree` write. Orchestrator ticket-role launches receive direct root read and delegation root read plus `.worktree` write, with no root workspace write delegation.
+- `SpawnPod` profile/inherit handling continues to replace child direct scope with the explicit delegated child scope and resets child delegation unless explicitly provided; profile/default scope does not leak into child direct authority.
+- Pod metadata restore uses saved manifest snapshots when present, so saved scope/delegation are preserved instead of being overwritten by current profile/default launch policy.
+- One-file manifest loading still rejects missing/empty concrete `scope.allow`; the retained user-profile scope compatibility path is separated from builtin role authority and is overwritten by launch/delegation policy on fresh role launches.
+
+Validation performed:
+- `cargo test -p manifest --quiet`
+- Focused pod tests for normal startup launch policy, orchestrator launch policy, SpawnPod delegation scoping, and metadata snapshot restore.
+- `cargo test -p client ticket_role --quiet`
+- `cargo build -p yoi`
+- `cargo fmt --check`
+- `git diff --check cdb12af9..HEAD`
+
+Result: approve. No blocking requirement or design-boundary concern found.

+
+## Background
+
+Profile は reusable behavior / model / prompt / feature policy の単位であるべきだが、現在は concrete filesystem authority である `scope` / `delegation_scope` も持っている。これにより、runtime launch policy と Profile authority が衝突している。
+
+実際に起きた問題:
+
+- `builtin:default` の workspace write scope が role profile 継承に混ざり、Orchestrator direct scope が workspace write を要求した。
+- 暫定対応として `resources/profiles/orchestrator.lua` に `scope = "workspace_read"` / `delegation_scope = "workspace_write"` を置いたが、これは scalar replacement に依存した非自明な workaround である。
+- Orchestrator の本来の authority は mixed shape である。
+  - direct scope: original workspace root read
+  - delegation scope: original workspace root read + `<workspace>/.worktree` write
+- Profile の Lua API / merge semantics でこの mixed authority を表現しようとすると、`yoi.profile.extend()` の deep merge や authority-bearing field replacement の問題に引きずられる。
+- Restore では metadata snapshot を正本として尊重すべきであり、current Profile/default manifest 由来の scope で上書きしてはいけない。
+
+根本方針:
+
+```text
+Profile = reusable behavior / prompt / model / feature policy
+Launch policy = concrete runtime authority / workspace root / cwd
+metadata snapshot = restore 時の effective authority 正本
+```
+
+この Ticket は、Orchestrator delegation を狭めるだけでなく、built-in/Profile から concrete scope を外し、起動経路ごとの launch policy が effective `scope` / `delegation_scope` を確定する形へ整理する。
+
+## Requirements
+
+- Reusable Profiles から concrete filesystem authority を外す。
+  - Builtin role Profiles (`builtin:companion`, `builtin:orchestrator`, `builtin:coder`, `builtin:reviewer` など) は `scope` / `delegation_scope` を role behavior の正本として持たない。
+  - `resources/profiles/orchestrator.lua` の `scope = "workspace_read"` / `delegation_scope = "workspace_write"` workaround を解消する。
+  - Profile は model / worker instruction / feature policy / compaction 等の reusable behavior を担う。
+- Launch surface が concrete authority を構築する。
+  - normal TUI / Companion launch は workspace write など、その起動経路の policy に基づいて direct scope を付与する。
+  - Ticket Orchestrator launch は Orchestrator role policy に基づいて scope/delegation を付与する。
+  - SpawnPod / role child launch は explicit delegated child scope を child direct scope として渡す。
+  - Child delegation scope は明示的に必要な場合のみ付与し、profile inheritance から暗黙に継承しない。
+- Orchestrator launch policy を以下にする。
+
+```text
+direct scope:
+  read  <original workspace root>
+
+delegation_scope:
+  read  <original workspace root>
+  write <original workspace root>/.worktree
+```
+
+- Reviewer/Coder child launch が必要とする root read と implementation worktree write を Orchestrator が再委譲できること。
+- Orchestrator が child に original workspace root write を委譲できないこと。
+- Restore path は metadata snapshot を尊重する。
+  - metadata snapshot がある場合、current profile/default/launch policy で scope/delegation_scope を上書きしない。
+  - 新規 launch で保存される metadata snapshot には launch policy 適用後の effective scope/delegation_scope が入る。
+- Existing Profile scope support の扱いを明確にする。
+  - この Ticket で Profile schema から完全削除するか、built-in role Profiles では禁止/無視しつつ user Profile support を deprecated として残すかは実装時に決めてよい。
+  - ただし built-in role launch の concrete authority は Profile scope に依存しないこと。
+- `00001KTZY8HK2` の Lua/profile replacement API は、この Ticket の前提にしない。
+  - scope 問題は Profile replacement API で解くのではなく、concrete authority を launch policy へ移すことで解く。
+  - scope 以外の field replacement が必要なら `00001KTZY8HK2` を後続の別問題として扱う。
+
+## Acceptance criteria
+
+- Builtin Orchestrator Profile の resolved reusable behavior から broad `delegation_scope = "workspace_write"` 依存がなくなる。
+- Fresh Orchestrator launch の effective manifest が以下を満たす test がある。
+  - direct scope allows read on original workspace root
+  - direct scope does not allow write on original workspace root
+  - delegation scope allows read on original workspace root
+  - delegation scope allows write under original workspace `.worktree`
+  - delegation scope does not allow write on original workspace root outside `.worktree`
+- Reviewer/Coder launch validation can be satisfied by the narrowed Orchestrator delegation scope.
+- Scope allocator does not conflict with the Companion/top-level `yoi` Pod's workspace write allocation.
+- Normal Companion/TUI launch still receives the expected workspace write direct scope from launch policy, not from reusable Profile authority.
+- SpawnPod child config still replaces inherited/profile scope with the explicitly delegated child scope.
+- Restore from metadata snapshot preserves saved scope/delegation_scope and does not reapply current Profile/launch default authority over the snapshot.
+- Tests cover at least:
+  - Profile resolution no longer leaking default workspace write into Orchestrator authority
+  - launch policy authority for Orchestrator
+  - launch policy authority for normal top-level/Companion launch where practical
+  - restore snapshot preservation
+  - child delegation validation for root read + worktree write
+- Validation: focused scope/profile/client/pod tests and `cargo build -p yoi`. Run `nix build .#yoi` only if Cargo.lock, packaging, or resource inclusion changes require it.
+
+## Out of scope
+
+- General Plugin/MCP permission design.
+- OS-level sandboxing of child processes.
+- Designing a full replacement/clear Lua API for every Profile field.
+- Full removal of user Profile `scope` compatibility unless the implementation chooses that as the cleanest route and updates tests/docs accordingly.
+
+## Related work
+
+- Profile replacement/clear semantics follow-up: `00001KTZY8HK2`
+- Restore should preserve metadata manifest snapshot: `9be3f132`
+- Orchestrator role profile: `resources/profiles/orchestrator.lua`
+- SpawnPod child scope/delegation path: `crates/pod/src/spawn/tool.rs`

+## Decision
+
+決定:
+- 旧方針の「Orchestrator delegation scope だけを狭める」ではなく、1 Ticket にまとめて「Profile から concrete scope を外し、launch policy が runtime authority を付与する」方針に広げる。
+- Profile は reusable behavior / prompt / model / feature policy を持つ層とし、filesystem `scope` / `delegation_scope` は起動経路が concrete workspace/cwd とともに決める。
+- Orchestrator の desired effective authority は launch policy で `direct read workspace` + `delegation read workspace, write workspace/.worktree` として構築する。
+- Lua/profile replacement API (`00001KTZY8HK2`) はこの scope 問題の前提にしない。scope 以外の replacement が必要なら後続として扱う。

+Routing decision: queued_waiting_conflict
+
+Reason:
+- Ticket is queued and appears implementation-ready, but it touches Profile concrete scope / launch policy surfaces.
+- `00001KTZY8HK2` was also queued and accepted in this routing pass for Profile API/resource migration (`extend` removal). Running both profile-surface migrations in parallel is likely to create merge conflicts and unclear review boundaries.
+- No missing requirement or dependency blocker was identified; this is a conflict/migration-order wait.
+
+Next action:
+- Keep queued for now.
+- Re-evaluate after `00001KTZY8HK2` is merged/validated, or if human explicitly authorizes parallel work despite conflict risk.

+
+<!-- event: decision author: orchestrator at: 2026-06-14T06:35:25Z -->
+
+## Decision
+
+Routing decision: implementation_ready
+
+Reason:
+- The previous conflict/wait on `00001KTZY8HK2` is resolved: profile extend removal has been reviewed, merged, validated, and marked done.
+- Ticket remains queued, has implementation-ready requirements/acceptance criteria, and relation records are non-blocking `related` links only.
+- Risk flags are scope/delegation/profile/launch/restore, but binding invariants and acceptance tests are concrete.
+
+Evidence checked:
+- Ticket body/thread/relations/orchestration-plan records.
+- Completed `00001KTZY8HK2` status and validation.
+- Orchestrator worktree clean state.
+
+IntentPacket:
+- Move concrete filesystem `scope` / `delegation_scope` out of reusable Profiles and into launch policy/effective metadata construction. Preserve restore snapshot authority and explicit child delegation behavior.
+
+Binding decisions / invariants:
+- Profiles own reusable behavior/model/prompt/feature policy, not concrete runtime authority.
+- Fresh Orchestrator launch effective authority: direct read original workspace; delegation read original workspace + write original workspace `.worktree`; no root workspace write delegation.
+- Normal Companion/TUI launch still gets expected workspace write direct scope from launch policy.
+- SpawnPod child direct scope is explicit delegated child scope, not inherited/profile scope.
+- Restore preserves metadata snapshot and does not reapply current profile/default launch authority over saved scope.
+
+Validation:
+- focused scope/profile/client/pod/spawn/restore tests, `cargo build -p yoi`, `cargo fmt --check`, `git diff --check`; `nix build .#yoi` if packaging/resource changes warrant or feasible.

+- `crates/pod/src/spawn/tool.rs`
+
+実装内容:
+- Builtin reusable Profiles から concrete filesystem `scope` / `delegation_scope` を削除した。
+- Profile resolution の implicit default workspace-write scope を廃止し、Profiles without scope を empty scope として解決可能にした。
+- Fresh profile launch の effective authority を `pod` entrypoint の launch policy で付与するようにした。
+  - normal Companion/TUI/default profile launch: workspace write direct scope（`.worktree` write deny）+ workspace read / `.worktree` write delegation。
+  - Ticket Orchestrator role launch: original workspace read direct scope + original workspace read / `<workspace>/.worktree` write delegation。root workspace write delegation は付与しない。
+  - Ticket Intake/Reviewer role launch: workspace read direct scope。
+  - Ticket Coder role launch: workspace write direct scope。
+- Single-file `--manifest` mode は従来どおり concrete `scope.allow` を要求し、Profile launch policy と混同しないようにした。
+- SpawnPod child scope replacement path は維持し、narrow Orchestrator delegation で Coder/Reviewer 用の root-read + implementation-worktree-write validation が成立することをテストした。
+- Existing user Profile `scope` / `delegation_scope` compatibility は deprecated-compatible path として残した（Ticket の選択肢に沿って、builtin role launch authority は Profile scope に依存しない）。
+

+
+## Background
+
+Workspace Panel の Ticket row は現在 1 行に `state / title / status / action` を圧縮している。これにより、canonical state と relation / queue blocker から導出される execution gate が混ざりやすい。
+
+例: `state: ready` かつ unresolved `depends_on` がある Ticket は、正本としては ready のままでよい。しかし Panel では queue 可能ではなく、`Gate: waiting` として見せる必要がある。現在の実装では relation blocker が `PanelRowKind::Blocked` / red / `Edit` に寄り、正常な依存待ちが error や人間入力要求のように見える。
+
+Panel の Ticket 表示を default 2 行にして、1 行目に正本 state/title、2 行目に Ticket id と derived gate/action/reason を表示する。選択状態は三角 `▶` ではなく、複数行をまとめる左罫線 `|` で示す。
+
+## Target layout
+
+Default Ticket row is two visual lines:
+
+```text
+  ready  Extend pod::feature API for external protocol-backed capability providers
+  00001KTR81P9X | Gate: waiting · depends_on 00001KV0SP0TY
+```
+
+Selected Ticket row uses a left vertical marker instead of a triangle so the two lines read as one selected item:
+

+
+## Requirements
+
+- Ticket rows in Workspace Panel render as two visual lines by default.
+  - Line 1: canonical workflow state + title.
+  - Line 2: ticket id + derived gate/action/reason summary.
+- Preserve the Ticket schema model.
+  - Do not add a persisted `waiting` state.
+  - Continue treating `state` as canonical lifecycle state.
+  - Derive gate/waiting/queueable from relations and current Panel context.
+- Relation blockers should be displayed as execution gate information, not as canonical state replacement.
+  - `state: ready` with unresolved `depends_on` shows `ready` on line 1.
+  - Line 2 shows `Gate: waiting · depends_on <id>`.
+  - Queue action is disabled/not offered while blockers are unresolved.
+  - Normal dependency wait should not use red/error styling or `Edit` as the primary action.
+- Keep truly problematic states visually distinct.
+  - Invalid/corrupt/unusable Ticket data or user-decision-required blockers may still use stronger warning styling.
+  - Normal relation ordering waits should use a waiting/amber/dim style rather than red.
+- Replace selected-row triangle marker with a multi-line grouping marker.
+  - Selected Ticket row uses `|` on each visual line.
+  - Non-selected Ticket row uses leading spaces aligned with the selected marker.
+  - Pod rows may keep existing one-line marker behavior unless changing them is necessary for layout consistency.
+- Update list selection and scrolling to account for multi-line Ticket rows.
+  - Selection remains one logical Ticket per two visual lines.
+  - Keyboard up/down moves by logical row, not visual line.
+  - Mouse click on either visual line selects the same Ticket and does not dispatch the action.
+  - Mouse wheel behavior remains intact.
+- Keep row layout robust for narrow terminals.
+  - Truncate title and gate summary with ellipsis.
+  - Avoid brittle fixed-width column alignment beyond small state/id labels.
+- Update target/action status line wording as needed.
+  - Selected ready/waiting Ticket should communicate `queue disabled` or `waiting for <blocker>` instead of simply `ready · Enter Edit`.
+
+## Acceptance criteria
+
+- Workspace Panel unit tests cover two-line Ticket row rendering for at least queueable ready, ready+waiting, planning, queued/inprogress, and done/closed cases where practical.
+- A ready Ticket with unresolved `depends_on` renders line 1 with `ready` and line 2 with `Gate: waiting` plus blocker identity.
+- The same ready+waiting Ticket does not have `NextUserAction::Queue` and does not use `NextUserAction::Edit` merely because of a normal dependency wait.
+- The ready+waiting Ticket is not rendered with the red/UserReply priority used for human-error/user-reply states.
+- Selected Ticket rows use `|` on all visual lines belonging to that Ticket; no `▶` triangle is used for those multi-line rows.
+- Mouse click on either visual line selects the same logical Ticket without dispatching its action.
+- Existing mouse wheel behavior continues to scroll/select as before.
+- Existing Panel E2E expectations are updated or extended if they depend on one-line rows or triangle markers.
+- Validation: focused `tui` tests, affected E2E if practical, `cargo build -p yoi`, and `nix build .#yoi`.
+
+## Non-goals
+
+- Adding a persisted `waiting` Ticket state.
+- Redesigning the whole Panel into full cards or a detail pane.
+- Changing Ticket lifecycle transition rules.
+- Reworking Pod row layout unless required for shared rendering primitives.
+
+## Related work
+
+- Ready Ticket blocked by dependency example: `00001KTR81P9X` depends on `00001KV0SP0TY`.
+- Ticket relation blockers are already surfaced by `TicketShow` and `WorkspacePanelViewModel`.
+- Mouse selection / wheel behavior follow-up E2E: `00001KV10SN02`.

+## Decision
+
+Routing decision: implementation_ready
+
+Reason:
+- Ticket is queued and specifies a bounded Workspace Panel row layout change: two-line Ticket rows separating canonical state from derived gate/action/reason.
+- Relation checks show related examples only, no blockers. `00001KV10SN02` E2E mouse/wheel coverage is done and can be updated as needed.
+- Risk is TUI layout/mouse selection; acceptance criteria are concrete.
+
+IntentPacket:
+- Render Ticket rows as two visual lines, use `|` selected grouping marker, show canonical state/title on line 1 and id/gate/action/reason on line 2, and adjust selection/mouse/scrolling logic accordingly.
+
+Binding invariants:
+- Do not add persisted `waiting` state or change Ticket lifecycle.
+- Normal relation waits are gate information, not error/human-reply styling.
+- Mouse click on either visual line selects the same logical Ticket and does not dispatch actions.
+
+Validation:
+- focused TUI row/layout/mouse tests, affected E2E if practical, `cargo build -p yoi`, `git diff --check`, `cargo fmt --check`; `nix build .#yoi` if feasible.

+
+## Implementation report
+
+Implemented Workspace Panel Ticket row rendering as two visual lines.
+
+Changes:
+- Ticket action rows now render a state/title line and a separate detail line containing Ticket id, gate, action, and reason.
+- Selection stays logical per Ticket row: selected Ticket visual lines use the same `|` marker, and contiguous hit boxes for the same Ticket are grouped so mouse clicks on either line select the same Ticket without dispatching actions.
+- Relation blockers are shown as gate/wait information with queue disabled wording and `Wait` action rather than as blocked/error/human-reply styling; no persisted `waiting` lifecycle state was added.
+- Updated focused row layout, waiting-gate, and mouse hit-testing tests.
+
+Validation:
+- PASS: `cargo test -p tui panel_ticket --lib`
+- PASS: `cargo test -p tui row_hit_testing --lib`
+- PASS: `cargo test -p tui mouse_click --lib`
+- PASS: `cargo test -p tui ready_ticket_with_waiting_gate --lib`
+- PASS: `cargo test -p tui workspace_panel_marks_ready_ticket_with_unresolved_relation_waiting_gate --lib`
+- PASS: `cargo test -p yoi-e2e --features e2e --test panel -- --nocapture`
+- PASS: `cargo build -p yoi`
+- PASS: `cargo fmt --check`
+- PASS: `git diff --check`
+- NOTE: `cargo test -p tui --lib` was also attempted and failed in pre-existing/unrelated tests: `multi_pod::tests::orchestrator_launch_context_uses_orchestration_root_for_runtime_workspace`, `spawn::tests::profile_choices_include_builtin_and_project_default_marker`, and `spawn::tests::profile_choices_use_project_registry_default`. The failures assert unrelated orchestration/profile defaults and are outside this Ticket's row/layout/mouse changes.
+- NOT RUN: `nix build .#yoi` (skipped as nonessential here; it may create root-level build output symlinks and is heavier than the scoped TUI/panel validation).
+
+Risks:
+- Ticket rows now consume two terminal lines, so very short panel areas may display fewer logical Ticket rows before clipping.
+
+
+---
+
+<!-- event: review author: hare at: 2026-06-14T06:37:08Z status: approve -->
+
+## Review: approve
+
+Approve.
+
+Evidence:
+- Reviewed `git diff f709fc10..HEAD` for implementation commit `645d048d`.
+- Ticket action rows now expand each Ticket into two selectable visual rows: the first renders canonical state plus title, the second renders Ticket id, derived gate, action, and reason. The selected marker is the `| ` grouping marker on both visual lines, and the title line no longer embeds the Ticket id.
+- Hit testing merges adjacent visual rows with the same `PanelRowKey`, so both Ticket visual lines select the same logical row/hitbox; mouse selection does not dispatch by itself, with dispatch still requiring the existing blank-Enter path.
+- Relation blockers are derived from relation data into `Wait`/queue-disabled gate text and preserve the canonical workflow state rather than introducing a persisted `waiting` lifecycle state or the old blocked/edit/human-reply row class.
+- Short-area/list-row slicing remains bounded by available height and hitboxes ignore out-of-area rows, so very small panel areas degrade without panics.
+
+Validation:
+- `cargo test -p tui panel_ticket --lib` — passed (3 tests).
+- `cargo test -p tui row_hit_testing --lib` — passed (1 test).
+- `cargo test -p tui mouse_click --lib` — passed (2 tests).
+- `cargo test -p tui ready_ticket_with_waiting_gate --lib` — passed (1 test).

+- `cargo build -p yoi` — passed.
+- `cargo fmt --check` — passed.

+
+Reviewer result:
+- `approve`。Ticket rows are two visual lines with canonical state/title separated from id/gate/action/reason; selected rows use `|` grouping marker on both lines; click/hitbox groups both visual lines into one logical row; relation waits remain derived gate info rather than persisted state.

+
+## Background
+
+`yoi panel` は Ticket-enabled workspace の主要操作面である。invalid / corrupt / unreadable な Ticket record が1件あるだけで、他の正常な Ticket の表示・Queue・Intake / Orchestrator 導線まで巻き添えで失われると、復旧作業と通常運用が難しくなる。
+
+ユーザー依頼:
+
+> InvalidなTicketがあった場合にPanelのチケット機能全般が無効化されるのではなく、
+
+Intake で関連コードを確認したところ、`crates/tui/src/workspace_panel.rs` の `build_ticket_rows` は次のように全体 `Result<Vec<PanelRow>>` になっている。
+
+- `backend.list(TicketFilter::all())?` が失敗すると Ticket rows 全体が失敗する。
+- 各 summary に対する `backend.show(TicketIdOrSlug::Query(summary.id.clone()))?` が1件でも失敗すると Ticket rows 全体が失敗する。
+- 呼び出し側はその error を `Ticket rows unavailable: ...` diagnostic として扱い、正常 Ticket rows も表示されない。
+
+したがって、本件は個別 Ticket record の partial failure handling として concrete bugfix にできる。
+
+## Requirements
+
+- Workspace Panel は invalid / corrupt / unreadable な Ticket record が一部にあっても、正常な Ticket rows を表示し続ける。
+- 正常な Ticket に対する既存の Panel action を維持する。
+  - planning clarification / Intake launch
+  - ready Ticket の Queue
+  - queued / inprogress / done / closed など既存 state 表示
+  - Orchestrator / Companion 関連の既存導線
+- invalid Ticket の存在は隠さない。
+  - header diagnostic、専用 placeholder row、または bounded detail で、どの Ticket/path が問題か分かるようにする。
+  - raw secret-like content や巨大ログは表示しない。
+- invalid Ticket には危険な lifecycle action を出さない。
+  - Queue / Close / planning return などの action は、正常に読めた Ticket に限定する。
+- Ticket config 自体が unusable な場合は、従来通り Ticket 機能を使えない状態としてよい。
+  - 本件は「Ticket backend/config 全体が壊れている」ケースではなく、「個別 Ticket record が壊れている」ケースの partial failure handling。
+- `TicketDoctor` / backend diagnostics と意味がずれないようにする。
+  - Panel 独自の silent skip ではなく、ユーザーが修復すべき record を認識できる。
+
+## Acceptance criteria
+
+- 1件の invalid Ticket record がある状態でも、Panel は正常な Ticket rows を表示する。
+- 正常な ready Ticket では Queue action が引き続き利用できる。
+- 正常な planning Ticket では clarification / Intake 導線が引き続き利用できる。
+- invalid Ticket は bounded diagnostic または placeholder row として見える。
+- invalid Ticket に対して Queue / Close / lifecycle mutation などの action は提示されない。
+- Panel header / diagnostics は「Ticket 全体 unavailable」ではなく「一部 Ticket を読み込めなかった」ことを示す。
+- Ticket config が unreadable / backend root が unusable な場合の既存 degraded behavior は壊さない。
+- Focused tests で、少なくとも次を確認する。
+  - valid + invalid が混在する Ticket backend で valid rows が残る。
+  - invalid row/diagnostic が bounded に出る。
+  - valid Ticket の action が維持される。
+  - config unusable ケースは従来通り全体 unavailable。
+
+## Binding decisions / invariants
+
+- invalid Ticket を理由に、正常 Ticket の Panel 操作を巻き添えで止めない。
+- invalid Ticket record を Panel が自動修復・自動削除しない。
+- invalid Ticket に対して lifecycle mutation action を出さない。
+- Ticket lifecycle authority / state schema は変更しない。
+- Ticket backend config 全体が unusable な場合と、個別 record の partial failure は区別する。
+- 正常 Ticket の lifecycle mutation は、既存の typed Ticket backend / Panel action path を通す。
+
+## Implementation latitude
+
+- invalid Ticket の表示方法は実装側に裁量を残す。
+  - header diagnostic のみ
+  - disabled/error placeholder row
+  - diagnostics detail view / F2 detail への誘導
+- `LocalTicketBackend::list` を lossy にするか、Panel 側で per-Ticket load を recover するかは実装側判断でよい。
+- backend に partial diagnostic API を足す必要がある場合は、Panel 専用の ad hoc parsing ではなく typed boundary を保つ。
+- `TicketDoctor` の診断ロジックを再利用できるならよいが、Panel 起動ごとに重すぎる full doctor を必須にしない。
+
+## Readiness
+
+- readiness: implementation_ready
+- risk_flags: [tui-panel, ticket-backend, partial-failure, diagnostics]
+
+## Escalation conditions
+
+- `TicketBackend::list` の public semantics を変更しないと実現できない場合。
+- invalid Ticket の path / id を安全に特定できず、diagnostic 表示の責務境界が曖昧な場合。
+- Panel action dispatch が row identity を valid Ticket と invalid placeholder で安全に分けられない場合。
+- `TicketDoctor` と Panel diagnostics の severity / wording が矛盾する場合。
+- invalid Ticket の内容を読まないと UI 表示できない設計になり、secret-like content 露出リスクが出る場合。
+
+## Validation
+
+- `cargo test -p tui workspace_panel --lib`
+- 必要に応じて `cargo test -p ticket`
+- `cargo fmt --check`
+- `git diff --check`

+- Ticket body / thread / artifacts、relation、OrchestrationPlan、Orchestrator workspace state を確認した。要件・受け入れ条件・invariants は実装可能な粒度で揃っており、planning に戻す concrete missing information はない。
+- ただし現在 `00001KV09WYC6` の Coder Pod が稼働中で、同じ Panel / `crates/tui/src/workspace_panel.rs` 周辺を主対象としている。
+- 本 Ticket も Panel Ticket row / partial failure handling を扱うため、並行実装すると row model/action/diagnostic 周辺で conflict risk が高い。
+- 既に `00001KTFY8V80` と `00001KV09WYC6` の2件が inprogress で Coder capacity を使用中。現時点では追加 spawn せず、`00001KV09WYC6` の結果を取り込んでから routing acceptance する。

+Reason:
+- 以前の waiting reason は `00001KV09WYC6` と同じ Panel row/action surface の conflict risk だったが、`00001KV09WYC6` は reviewer approve、orchestration branch への merge、focused validation、Ticket `done` まで完了した。
+- Ticket body / thread / relations / orchestration plan / current Orchestrator workspace を再確認した。blocking relation はなく、planning に戻す concrete missing information はない。
+- 本 Ticket は invalid/corrupt/unreadable individual Ticket record に対する Panel partial failure handling として concrete であり、残る不確実性は backend/list/show error handling と Panel row/diagnostic 表現の実装戦術に閉じている。

+Evidence checked:
+- Ticket body/thread: Background, requirements, acceptance criteria, invariants, implementation latitude, escalation conditions, validation を確認。
+- Ticket relations: blocker なし。
+- OrchestrationPlan: `00001KV09WYC6` との prior conflict/waiting note を確認。先行 Ticket 完了により blocker は解消。
+- Orchestrator workspace: `/home/hare/Projects/yoi/.worktree/orchestration` は clean、`81667a9a` 上。
+- Active Pods: `00001KTFY8V80` reviewer running、coder idle。Panel implementation worker/reviewer for `00001KV09WYC6` は停止済み。

+
+IntentPacket:
+
+Intent:
+- Workspace Panel で個別 invalid/corrupt/unreadable Ticket record があっても、正常な Ticket rows と actions を表示・維持し、invalid record は bounded diagnostic/placeholder として見せる。

+- invalid Ticket record を Panel が自動修復・自動削除しない。
+- invalid Ticket には Queue / Close / planning return など lifecycle mutation action を出さない。
+- Ticket lifecycle authority / state schema は変更しない。

+- 正常 Ticket の lifecycle mutation は既存 typed Ticket backend / Panel action path を通す。
+- invalid record の content や secret-like content を UI/diagnostic に漏らさない。
+
+Requirements / acceptance criteria:
+- valid + invalid Ticket が混在しても valid rows は残る。
+- 正常 ready Ticket の Queue action、正常 planning Ticket の clarification/Intake 導線を維持する。
+- invalid Ticket は bounded diagnostic または disabled placeholder row として見える。
+- invalid Ticket に lifecycle mutation action を提示しない。
+- Panel header/diagnostics は全体 unavailable ではなく一部読み込み失敗を表す。
+- backend root/config unusable の既存 degraded behavior は壊さない。
+- Focused tests で partial failure、bounded invalid indication、valid action preservation、config unusable case を確認する。

+- Ticket backend config failure との区別。
+- diagnostics の boundedness と secret-like content 非露出。
+- prior `00001KV09WYC6` の Ticket-associated Intake row behavior との整合。

+Changed files:
+- `crates/ticket/src/lib.rs`
+  - Added tolerant `LocalTicketBackend::list_partial(...)` and `show_partial(...)`.
+  - Added bounded/sanitized `TicketInvalidRecord` reporting.
+  - Preserved strict existing `TicketBackend::list/show` semantics.
+  - Added ticket backend test for valid records surviving peer invalid record failures.
+- `crates/tui/src/workspace_panel.rs`
+  - Panel now uses partial ticket loading.
+  - Valid Ticket rows remain visible/actionable when sibling Ticket records are invalid.
+  - Invalid records render as disabled diagnostic placeholder rows.
+  - Invalid placeholder rows have no lifecycle actions and no `ticket` action identity.
+  - Header diagnostics indicate partial Ticket load failure with bounded placeholder count.
+  - Added focused Panel tests covering valid ready Queue action, valid planning Clarify/Intake path, associated Intake row adjacency, invalid row bounded/non-actionable behavior, secret-like content non-exposure, and backend config unusable behavior.
+- `crates/tui/src/multi_pod.rs`
+  - Added rendering/selection support for invalid Ticket placeholder rows.
+  - Invalid placeholder rows are shown as ticket-section diagnostics but remain action-disabled.
+
+Validation reported by coder:
+- Passed: `cargo test -p tui workspace_panel --lib`
+- Passed: `cargo test -p ticket partial_list_and_show --lib`
+- Passed: `cargo fmt --check`
+- Passed: `git diff --check`
+
+Repository status:
+- Child implementation worktree clean after commit.
+
+Residual risks / blockers:
+- None known.
+- Strict backend list/show behavior was preserved; new partial methods are opt-in for Panel tolerance.

+
+## Review: request changes
+
+Review result: request_changes
+
+Blocker:
+- A corrupt current-ticket relation artifact can still produce an actionable normal Ticket row.
+
+Details:
+- New tolerant relation loading records relation-artifact failures as `TicketInvalidRecord`, but still returns an `Ok(Ticket)` with lossy/omitted relations.
+- `LocalTicketBackend::show_partial` returns `ticket_from_dir_tolerant(...)` as successful partial details.
+- `relation_view_for_meta_tolerant` builds a relation view from remaining records after `all_ticket_relation_records_tolerant` records relation read errors.
+- Panel unconditionally emits a normal actionable `ticket_row(...)` whenever `show_partial` returns `Ok`, and only extends `invalid_records` for diagnostics.
+- A ready row can therefore still receive `NextUserAction::Queue`.
+
+Consequence:
+- If a ready Ticket's own `artifacts/relations.json` is corrupt/unreadable, Panel can show both:
+  1. a normal ready Ticket row with `Queue`, and
+  2. an invalid placeholder for the same Ticket id.
+- This violates the invariant that invalid/corrupt Ticket records must not expose Queue/Close/planning-return/lifecycle mutation actions.
+- It is also risky because malformed relations may hide dependency/blocker authority; Queue must not be exposed for that same corrupt Ticket record.
+
+Required changes:
+- If partial detail loading reports an invalid record for the same Ticket id being rendered, do not also render that Ticket as an actionable normal row.
+- Replace it with a disabled invalid placeholder, or otherwise guarantee no lifecycle mutation action is available for that id.
+- Add focused coverage for a valid `item.md` with corrupt/unreadable current Ticket detail/artifact, preferably malformed `artifacts/relations.json`, asserting:
+  - Ticket id is visible as invalid diagnostic/placeholder.
+  - no Queue/Close/lifecycle action is available for that Ticket id.
+  - other valid Ticket rows/actions remain available.
+
+Evidence checked:
+- Reviewed implementation diff `a1c8264b..b83b9e4e`.
+- Inspected:
+  - `crates/ticket/src/lib.rs`
+  - `crates/tui/src/workspace_panel.rs`
+  - `crates/tui/src/multi_pod.rs`
+  - Ticket `00001KV3A5CNH` item.
+
+Positive findings:
+- Strict `TicketBackend::list/show` behavior remains unchanged; partial behavior is opt-in.
+- Mixed valid/invalid item frontmatter is covered by focused tests.
+- Panel creates disabled invalid placeholder rows with no `next_action`.
+- Backend config unusable remains a whole-ticket degraded case in tests.
+- Existing associated Intake row behavior is covered for a valid ready Ticket.
+
+Validation performed by reviewer:
+- Passed: `git diff --check a1c8264b..HEAD`
+- Passed: `cargo fmt --check`
+
+Validation not run:
+- `cargo test` was not rerun because review scope was read-only and Cargo writes build artifacts.
+
+Conclusion:
+- Changes requested. Do not integrate until current-ticket detail/artifact corruption cannot expose lifecycle actions and focused coverage is added.

+## Implementation report
+
+Follow-up implementation report after reviewer request_changes:
+
+New commit:
+- `456722c3 fix: disable tickets with invalid detail records`
+
+Changed file in follow-up:
+- `crates/tui/src/workspace_panel.rs`
+
+Blocker resolved:
+- `build_ticket_rows(...)` now checks `show_partial(...)` diagnostics for an invalid record whose label matches the Ticket id currently being rendered.
+- If the current Ticket id is reported invalid during partial detail loading, Panel no longer emits the normal actionable `ticket_row(...)`.
+- The invalid record flows through the existing bounded invalid placeholder/diagnostic path, so the Ticket id remains visible but has no lifecycle action.
+
+Behavior after fix:
+- A ready Ticket with valid `item.md` but malformed `artifacts/relations.json` is shown only as an invalid diagnostic placeholder.
+- It cannot receive Queue, Close, clarification/planning-return, or other lifecycle mutation actions.
+- Other valid Ticket rows continue to render normally and keep their actions.
+
+Coverage added:
+- `workspace_panel_disables_current_ticket_when_detail_artifact_is_invalid`
+- Test scenario:
+  - one ready Ticket with malformed `artifacts/relations.json`
+  - one separate valid ready Ticket
+- Assertions:
+  - corrupt Ticket id is visible as `PanelRowKey::InvalidTicket(...)`
+  - no normal `PanelRowKey::Ticket(...)` row exists for that corrupt id
+  - placeholder has no action and no Ticket action identity
+  - other valid ready Ticket still has `NextUserAction::Queue`
+  - header reports partial Ticket load failure
+
+Validation reported by coder:
+- Passed: `cargo test -p tui workspace_panel_disables_current_ticket_when_detail_artifact_is_invalid --lib`
+- Passed: `cargo test -p tui workspace_panel --lib`
+- Passed: `cargo fmt --check`
+- Passed: `git diff --check`

+## Review: approve
+
+Review result: approve
+
+Evidence checked:
+- Target worktree clean at `456722c3`.
+- Reviewed diff `a1c8264b..456722c3` and second-pass fix diff `b83b9e4e..456722c3`.
+- Confirmed backend partial/tolerant read paths:
+  - `LocalTicketBackend::list_partial`
+  - `LocalTicketBackend::show_partial`
+  - tolerant relation/state loading records invalid Ticket ids via `TicketInvalidRecord` instead of failing entire list/detail load.
+- Confirmed Panel row construction:
+  - uses `list_partial` and `show_partial`;
+  - collects invalid records into bounded diagnostics/placeholders;
+  - detects when `show_partial` reports an invalid record whose label matches the summary id being rendered;
+  - skips normal actionable `PanelRowKey::Ticket(id)` for that id;
+  - emits `InvalidTicket(id)` placeholder instead.
+- Confirmed invalid placeholder rows are diagnostics-only:
+  - `kind == PanelRowKind::InvalidTicket`
+  - `ticket == None`
+  - `next_action == None`
+  - `is_ticket_action()` excludes invalid rows
+  - lifecycle dispatch preparation only accepts `row.is_ticket_action()`.
+- Confirmed regression test for prior blocker:
+  - `workspace_panel_disables_current_ticket_when_detail_artifact_is_invalid`
+  - malformed `artifacts/relations.json` ready Ticket has no normal actionable row;
+  - disabled `PanelRowKey::InvalidTicket(corrupt.id)` placeholder exists;
+  - another valid ready Ticket keeps `Queue`.
+- Confirmed broader acceptance coverage remains:
+  - mixed valid/invalid records preserve valid ready/planning rows;
+  - invalid rows are capped and do not leak malformed state strings;
+  - backend config unusable remains separate whole-ticket degradation;
+  - valid Ticket-associated Intake rows remain adjacent to valid Ticket rows.
+
+Validation performed by reviewer:
+- Passed: `git diff --check a1c8264b..HEAD`
+- Passed: `cargo fmt --check`
+
+Validation not run:
+- `cargo test` was not run by reviewer because read-only review scope prevents writing build artifacts. Coder-reported passing tests were inspected as evidence.
+
+Conclusion:
+- Approved. No remaining blocker found.

+# E2E evidence for Ticket 00001KV3BQ7Q3
+
+Validation date: 2026-06-14
+Worktree: `/home/hare/Projects/yoi/.worktree/00001KV3BQ7Q3-panel-e2e-evidence`
+Branch: `impl/00001KV3BQ7Q3-panel-e2e-evidence`
+
+## Summary
+
+| Target merge behavior | Status | E2E scenario / assertion |
+| --- | --- | --- |
+| `802fa1f00f8725fe35336e083cd05652fee1409e` / `merge: rewind live refresh` | Pass for current fixture PTY E2E | `single_pod_rewind_picker_applies_without_escape_and_suppresses_duplicate_enter` spawns the real `yoi` binary under PTY, opens the rewind picker, applies the target without Esc/restart/restore, observes `rewind_applied` with restored composer text, and now also waits for the post-apply PTY stream to contain the unique live composer marker `rewind-live-refresh`. |
+| `02311883f7cda116676d8e179a14ad0be9e7a244` / `merge: panel mouse selection` | Pass for current fixture PTY E2E | `panel_mouse_click_selects_row_without_dispatching_action` spawns the real `yoi panel` PTY path, injects SGR mouse click input, observes `selection_changed` for the clicked row, and asserts no `action_requested` event was emitted by click alone. |
+| `db7bad7a64766c2039a4c10781801cb571027955` / `merge: panel quit latency` | Pass for bounded current fixture PTY E2E; original live-terminal latency remains outside this fixture | `panel_ctrl_c_exits_promptly_after_background_barrier` spawns the real `yoi panel` PTY path with a held `reload` background task, confirms that task is pending, sends Ctrl-C, and asserts clean process exit within `PanelHarness::default_exit_wait()` (1500 ms) plus `quit_requested` and `background_task_aborted { task: "reload" }` events. This guarantees that pending fixture background reload work is aborted and does not block quit past the threshold; it does not prove arbitrary live-terminal latency outside this fixture. |
+
+## Commands and results
+
+- `cargo fmt --check` — passed.
+- `cargo test -p yoi-e2e --features e2e --no-run` — passed; built `yoi-e2e` unit/integration test executables.
+- `cargo test -p yoi-e2e --features e2e` — passed: `yoi_e2e` unit test 1/1, `panel` integration tests 3/3, `rewind` integration test 1/1, doc-tests 0.
+- `cargo check -p yoi-e2e -p yoi -p tui` — passed.
+- `git diff --check` — passed.
+
+## Residual gaps / non-claims
+
+- These are automated fixture PTY confirmations only. They are not manual/live-terminal validation.
+- The mouse path uses the harness's SGR mouse injection through a PTY. It confirms the real `yoi panel` process path receives and handles the encoded click as intended, but it is not a hardware/terminal-emulator compatibility matrix.
+- The quit-latency assertion is bounded to the fixture's held `reload` task and 1500 ms threshold. It confirms pending fixture background work does not user-visibly block quit beyond that bound, but does not independently reproduce every historical live latency observation.

+
+## Background
+
+過去に以下の merge commit が、user-visible な TUI / Panel 挙動として十分な実経路確認なしに merge された、または merge 後に証明不足が問題化した。
+
+- `802fa1f00f8725fe35336e083cd05652fee1409e` — `merge: rewind live refresh`
+- `02311883f7cda116676d8e179a14ad0be9e7a244` — `merge: panel mouse selection`
+- `db7bad7a64766c2039a4c10781801cb571027955` — `merge: panel quit latency`
+
+特に Panel latency / mouse selection は、focused tests や code review だけでは実ユーザー経路の保証として不十分だった経緯がある。後続で E2E harness が整備されたため、現行の E2E システムで、これらの commit が意図した user-visible behavior を確認する。
+
+この Ticket は「過去の merge 判断を後付けで正当化する」ためではなく、現行 HEAD / 現行 E2E infrastructure において、対象 behavior が実プロセス PTY 経路で確認できるかを明示するための validation work item である。
+
+## Requirements
+
+- 対象 commit ごとに、確認すべき user-visible behavior を明確化する。
+  - `802fa1f0`: rewind picker で `Enter` 後、live TUI 表示が restart / restore なしに巻き戻し後状態へ更新されること。
+  - `02311883`: Panel mouse selection が実プロセス PTY 経路で動作し、click が selection を変え、click だけで action dispatch しないこと。
+  - `db7bad7a`: Panel quit latency 改善として意図された経路が、現行 E2E で bounded に確認できること。少なくとも pending background work が quit を user-visible に block しないことを確認し、元の latency 観測を直接保証できない場合はその gap を明示する。
+- 現行 E2E システムで各 behavior を確認する。
+- 既存 E2E coverage がある場合は、どの test / scenario がどの commit の behavior を確認しているかを実装報告に明記する。
+- 既存 E2E coverage が不足している場合は、最小限の E2E scenario / assertion を追加または更新して確認可能にする。
+- E2E で確認できない性質がある場合は、pass 扱いにせず、coverage gap として明示する。
+- 実ユーザー環境での manual/live confirmation と、fixture PTY E2E confirmation を混同しない。
+
+## Acceptance criteria
+
+- `802fa1f0`, `02311883`, `db7bad7a` の3件それぞれについて、現行 E2E での確認結果が pass / fail / coverage gap のいずれかとして記録されている。
+- pass とする場合は、対応する E2E test 名、assertion、実行 command、結果が実装報告に記録されている。
+- coverage gap とする場合は、何が現行 E2E では確認できないのか、追加 E2E が必要なのか、manual/live validation が必要なのかが明示されている。
+- mouse selection は、focused unit test ではなく実 `yoi` binary + PTY 経路で `selection_changed` 等の user-visible observer を確認している。
+- quit latency は、単に process が終了するだけでなく、latency / pending work / threshold の観点で何を保証しているかが明示されている。
+- rewind live refresh は、restart / restore なしの live 表示更新が E2E で確認されるか、未確認ならその不足が明示されている。
+- `cargo test -p yoi-e2e --features e2e` または同等の現行 E2E command が実行され、結果が記録されている。
+- E2E を追加・更新した場合、fixture-local HOME / XDG / runtime / workspace isolation と no-provider / no-network 前提を維持している。
+
+## Binding decisions / invariants
+
+- focused tests / code-path review だけで user-visible Panel/TUI behavior を確認済み扱いにしない。
+- E2E pass と manual/live user confirmation は別物として記録する。
+- 現行 E2E が確認していない behavior を、確認済みとして表現しない。
+- この Ticket の主目的は validation / evidence 整理であり、対象 behavior の大きな再設計や unrelated fix は行わない。
+- 対象 commit の historical merge decision を書き換えるのではなく、現行状態の evidence を追加する。
+
+## Implementation latitude
+
+- 既存 `yoi-e2e` scenario の再利用、test 名 / assertion の明確化、必要最小限の scenario 追加は実装者判断で行ってよい。
+- E2E observer / fixture helper に不足がある場合、production behavior に影響しない `e2e-test` feature gate 配下の補助を追加してよい。
+- latency threshold は既存 E2E の基準を優先し、変更が必要な場合は理由を実装報告に明記する。
+- 既存 E2E が flake する場合は、原因を切り分け、test hardening と behavior fix を混同しない。
+
+## Readiness
+
+- readiness: implementation_ready
+- risk_flags: [e2e, tui, panel, regression-evidence]
+
+## Escalation conditions
+
+- 現行 E2E infrastructure では対象 behavior を原理的に確認できず、実端末 manual validation や新しい harness 設計が必要な場合。
+- latency の再現・測定が既存 observer / threshold では意味を持たない場合。
+- mouse behavior が PTY SGR injection では pass するが、実端末 mouse 操作と乖離する疑いが残る場合。
+- 対象 behavior の確認中に actual regression が見つかり、validation ticket の範囲を超える修正が必要になった場合。
+
+## Validation
+
+- `cargo test -p yoi-e2e --features e2e`
+- 必要に応じて対象 E2E scenario の narrow run
+- E2E 追加・更新時:
+  - `cargo test -p yoi-e2e --no-run`
+  - `cargo fmt --check`
+  - `git diff --check`
+- 変更範囲に応じて `cargo check -p yoi-e2e -p yoi -p tui`
+

+- rewind live refresh は restart/restore なしの live 表示更新が E2E で確認されるか、不足を明示する。
+- `cargo test -p yoi-e2e --features e2e` または同等の現行 E2E command を実行し結果を記録する。
+
+Implementation latitude:
+- 既存 `yoi-e2e` scenario の再利用、test name/assertion の明確化、最小限の scenario 追加・更新は Coder 判断。
+- 不足する observer/helper は production behavior に影響しない `e2e-test` feature gate 配下で追加可。
+- latency threshold は既存 E2E 基準を優先し、変更が必要なら理由を報告する。
+- flake の hardening と behavior fix を混同しない。
+
+Escalate if:
+- 現行 E2E infrastructure では原理的に確認不能で、実端末 manual validation や新 harness 設計が必要。
+- latency の測定が既存 observer / threshold では意味を持たない。
+- PTY SGR injection と実端末 mouse 操作に乖離疑いが残る。
+- actual regression が見つかり、validation Ticket の範囲を超える修正が必要。
+
+Validation:
+- `cargo test -p yoi-e2e --features e2e` または必要な narrow E2E command。
+- E2E 追加・更新時は `cargo test -p yoi-e2e --no-run`, `cargo fmt --check`, `git diff --check`。
+- 変更範囲に応じて `cargo check -p yoi-e2e -p yoi -p tui`。
+
+Critical risks / reviewer focus:
+- PTY / real binary 経路であること。
+- unit/focused test と E2E evidence の混同防止。
+- coverage gap を pass と偽らないこと。
+- E2E fixture isolation / no-provider / no-network 維持。
+- recently merged Panel changes (`00001KV09WYC6`, `00001KV3A5CNH`) 後の現行 HEAD に対する evidence であること。

+## Summary
+
+| Target merge behavior | Status | E2E scenario / assertion |
+| --- | --- | --- |
+| `802fa1f00f8725fe35336e083cd05652fee1409e` / `merge: rewind live refresh` | Pass for current fixture PTY E2E | `single_pod_rewind_picker_applies_without_escape_and_suppresses_duplicate_enter` spawns the real `yoi` binary under PTY, opens the rewind picker, applies the target without Esc/restart/restore, observes `rewind_applied` with restored composer text, and now also waits for the post-apply PTY stream to contain the unique live composer marker `rewind-live-refresh`. |
+| `02311883f7cda116676d8e179a14ad0be9e7a244` / `merge: panel mouse selection` | Pass for current fixture PTY E2E | `panel_mouse_click_selects_row_without_dispatching_action` spawns the real `yoi panel` PTY path, injects SGR mouse click input, observes `selection_changed` for the clicked row, and asserts no `action_requested` event was emitted by click alone. |
+| `db7bad7a64766c2039a4c10781801cb571027955` / `merge: panel quit latency` | Pass for bounded current fixture PTY E2E; original live-terminal latency remains outside this fixture | `panel_ctrl_c_exits_promptly_after_background_barrier` spawns the real `yoi panel` PTY path with a held `reload` background task, confirms that task is pending, sends Ctrl-C, and asserts clean process exit within `PanelHarness::default_exit_wait()` (1500 ms) plus `quit_requested` and `background_task_aborted { task: "reload" }` events. This guarantees that pending fixture background reload work is aborted and does not block quit past the threshold; it does not prove arbitrary live-terminal latency outside this fixture. |
+
+## Commands and results
+
+- `cargo fmt --check` — passed.
+- `cargo test -p yoi-e2e --features e2e --no-run` — passed; built `yoi-e2e` unit/integration test executables.
+- `cargo test -p yoi-e2e --features e2e` — passed: `yoi_e2e` unit test 1/1, `panel` integration tests 3/3, `rewind` integration test 1/1, doc-tests 0.
+- `cargo check -p yoi-e2e -p yoi -p tui` — passed.
+- `git diff --check` — passed.
+
+## Residual gaps / non-claims
+
+- These are automated fixture PTY confirmations only. They are not manual/live-terminal validation.
+- The mouse path uses the harness's SGR mouse injection through a PTY. It confirms the real `yoi panel` process path receives and handles the encoded click as intended, but it is not a hardware/terminal-emulator compatibility matrix.
+- The quit-latency assertion is bounded to the fixture's held `reload` task and 1500 ms threshold. It confirms pending fixture background work does not user-visibly block quit beyond that bound, but does not independently reproduce every historical live latency observation.

+  - `tests/e2e/tests/rewind.rs`
+
+Findings:
+- `802fa1f0` / rewind live refresh: strengthened `single_pod_rewind_picker_applies_without_escape_and_suppresses_duplicate_enter` uses real `yoi` PTY fixture, applies rewind, observes `rewind_applied`, verifies restored composer text `rewind-live-refresh`, and waits for raw PTY output after the pre-rewind offset to contain that marker. This satisfies fixture PTY E2E evidence for restart/restore-free live display update.
+- `02311883` / panel mouse selection: existing `panel_mouse_click_selects_row_without_dispatching_action` uses real `yoi panel` PTY, SGR click injection, observes selection change, and asserts no `action_requested` from click alone. This is not just unit/code review coverage.
+- `db7bad7a` / panel quit latency: strengthened `panel_ctrl_c_exits_promptly_after_background_barrier` confirms pending `reload`, sends Ctrl-C, requires clean exit within `PanelHarness::default_exit_wait()` / 1500 ms, and asserts `background_task_aborted { task: "reload" }`. The evidence states the bounded guarantee precisely and does not overclaim arbitrary live-terminal latency.
+
+Residual gap representation:
+- Correctly represented. The evidence distinguishes automated fixture PTY E2E from manual/live-terminal validation, describes mouse coverage as SGR PTY injection rather than terminal-emulator matrix, and keeps the original live-terminal latency gap outside the fixture guarantee.
+
+Validation performed by reviewer:
+- Passed: `git diff --check 5e81bc38..HEAD`
+- Passed: `cargo fmt --check`
+- `git status --porcelain=v1` was clean.
+
+Validation not rerun by reviewer:
+- E2E tests/checks were not rerun in reviewer because they write to build/artifact locations. Coder-reported passing results were reviewed as evidence.
+
+Conclusion:
+- Approved. No blocker remains.

+## Implementation report
+
+Integration report:
+
+Merged implementation/evidence branch into orchestration branch:
+- branch: `impl/00001KV3BQ7Q3-panel-e2e-evidence`
+- implementation commit: `1f07e57a test: record panel tui e2e evidence`
+- merge commit: `b5e7ca98 merge: panel e2e evidence`
+
+Reviewer result:
+- `approve` recorded from `yoi-reviewer-00001KV3BQ7Q3`.
+
+Validation in Orchestrator worktree `/home/hare/Projects/yoi/.worktree/orchestration`:
+- Passed: `cargo fmt --check`
+- Passed: `cargo test -p yoi-e2e --features e2e --no-run`
+- Passed: `cargo test -p yoi-e2e --features e2e`
+- Passed: `cargo check -p yoi-e2e -p yoi -p tui`
+- Passed: `git diff --check`
+
+Per-target evidence outcome:
+- `802fa1f0` / rewind live refresh: pass for current fixture PTY E2E. Strengthened rewind E2E verifies post-apply PTY output contains the unique restored composer marker without restart/restore.
+- `02311883` / panel mouse selection: pass for current fixture PTY E2E. Existing Panel mouse E2E covers real `yoi panel` PTY, SGR click selection change, and no action dispatch on click alone.
+- `db7bad7a` / panel quit latency: pass for bounded fixture PTY E2E with residual live-terminal gap. Strengthened Panel quit E2E confirms pending reload background task is aborted and quit completes within the 1500 ms fixture threshold.
+
+Residual gaps:
+- Evidence is automated fixture PTY E2E, not manual/live-terminal validation.
+- Mouse coverage is SGR PTY injection through real process path, not a terminal-emulator compatibility matrix.
+- Quit latency evidence is bounded to fixture-held reload work and threshold, not every historical live latency scenario.
+
+Cleanup planned:
+- Stop related coder/reviewer Pods.
+- Remove only child implementation worktree/branch for this Ticket.
