 ## Goal
 
-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 is a protocol-backed integration layer on top of `pod::feature`. `pod::feature` supplies contribution/lifecycle/runtime-discovered registration substrate; MCP owns its own enablement, local server trust model, command/env/secret policy, and MCP-specific permission decisions. MCP is not the Plugin model, and Plugin permission policy is not implemented by feature-layer authority grants.
 
 ## Motivation / background
 
-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。
+Yoi needs to integrate with external capability providers without turning them into hidden context sources or bypassing ordinary Tool/Worker safety rules. MCP is useful because it can expose tools, resources, and prompts from local protocol servers, but those server-provided declarations and results are untrusted and must be normalized through Yoi's existing authority boundaries.
 
-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。
+The first MCP slice should focus on local stdio servers because they are concrete enough to implement and debug while keeping remote auth, OAuth, Streamable HTTP, registry distribution, sampling, and elicitation out of the initial trust boundary.
+
+A configured local MCP server runs as a local executable. Yoi feature authority does not sandbox that executable's OS-level side effects, so command/env/secret handling and explicit local trust policy are MCP-layer responsibilities rather than generic `pod::feature` grants.
 
 ## Strategy / design direction
 
-- Broad MCP integration Ticket は progress-container として使わず、この Objective に中期方針を移す。
-- 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。
+- Baseline the initial 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 become hidden context injection.
+  - They must be explicit tool operations with history records.
+- Use the normal Yoi ToolRegistry, 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.
+
+### Layering decisions
+
+- `pod::feature` is an API/contribution substrate.
+  - It owns contribution declarations, provider/service lifecycle hooks, diagnostics, runtime-discovered 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 provider-discovered tools/resources/prompts are exposed through the feature API and ordinary Yoi tool paths.
+
+### Concrete implementation tickets
+
+Completed prerequisites:
+
+- `00001KTR81P9X` — Extend `pod::feature` API for external protocol-backed capability providers.
+- `00001KV0SP0TY` — Remove feature-layer HostAuthority model.
+
+Concrete MCP implementation sequence:
+
+1. `00001KVHR3WRF` — MCP local stdio server config and trust policy.
+   - explicit config, command/env/secret redaction, local executable trust boundary, no auto-start.
+2. `00001KVHR3WRY` — MCP stdio JSON-RPC lifecycle client.
+   - subprocess lifecycle, initialize/capability negotiation, diagnostics, shutdown.
+3. `00001KVHR3WS6` — MCP tools/list registration into ToolRegistry.
+   - provider-discovered tools, stable namespacing, schema validation, untrusted metadata normalization, no tools/call yet.
+4. `00001KVHR3WSD` — MCP tools/call execution through ordinary Tool path.
+   - PreToolCall gate before server call, bounded result serialization, history path.
+5. `00001KVHR3WSN` — MCP resources/prompts as explicit tool operations.
+   - resources/list/read and prompts/list/get without hidden context injection.
+6. `00001KVHR3WSW` — MCP list_changed notification handling.
+   - deterministic safe refresh/diagnostic behavior without breaking tool schema or prompt-cache invariants.
+
+The old broad implementation Ticket `00001KTR82RB7` is superseded by this sequence and should not be used as an implementation work item.
+
+### Terminology
+
+Use `runtime-discovered` or `provider-discovered` for MCP tools/resources/prompts discovered from `tools/list`, `resources/list`, or `prompts/list`. Avoid `dynamic tools` / `dynamic registry` in new MCP design prose because those phrases imply that model-visible tool schemas may change during an active LLM run.
+
+The intended invariant is:
+
+```text
+provider-discovered at startup / provider initialization;
+registered into the ordinary ToolRegistry before model exposure;
+run-stable for the duration of a model request/run;
+refreshed only at a safe boundary or reported as a diagnostic.
+```
+
+### Later follow-ups
+
+- Richer MCP task/task-support integration if ordinary tool-call fallback is insufficient.
+- Streamable HTTP transport.
+- OAuth / remote auth.
+- Registry/package distribution.
+- Explicit MCP/Plugin bridge only if separately approved; do not conflate Plugin packages with MCP local server execution.
 
 ## Success criteria / exit conditions
 
-- `pod::feature` が external protocol-backed capability provider を表現できる。
-- 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。
+- A local mock MCP server can be configured explicitly and initialized.
+- Discovered MCP tools appear as ordinary Yoi tools with stable namespacing.
+- Tool calls go through ordinary permission and history paths.
+- MCP resources/prompts are explicit operations, not hidden context injections.
+- MCP result forms are bounded and safely serialized.
+- Secret values, command/env details, and server diagnostics are redacted where required.
+- 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.
 
 ## Decision context
 
-- `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。
-- `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。
-- `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。
-- 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。
-- `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。
+- MCP is not the Plugin model; it is a protocol-backed integration layer using `pod::feature` substrate.
+- `pod::feature` should provide contribution/lifecycle/runtime-discovered registration plumbing, not MCP server trust policy or Plugin package permission policy.
+- MCP resources and prompts must never be hidden context injection. They are explicit operations recorded through ordinary history/tool paths.
+- Provider-discovered tools are discovered at startup/provider initialization and registered before model exposure; model-visible schemas remain run-stable during a request/run.
+- Local stdio server execution is a user/config trust decision. Yoi does not sandbox the local executable merely because it is configured through MCP.

+---
+
+## Goal
+
+Build Yoi's Plugin platform as a coherent extension system: packages are discovered and inspected safely, enabled explicitly, registered through typed Plugin surfaces, executed in a sandboxed runtime, constrained by Plugin-layer grants, and authored through SDK/templates rather than raw runtime ABI details.
+
+The long-term platform goal is not merely to run Wasm. It is to make Plugin packages a durable, inspectable, permissioned, and authorable extension layer for Tools first, then host APIs (`https`, `fs`), and later Service / Ingress surfaces when concrete needs justify them.
+
+## Motivation / background
+
+The current Plugin foundation is already substantial:
+
+- package discovery and explicit enablement resolver;
+- Tool surface registration through the ordinary ToolRegistry/model-visible schema path;
+- minimal sandboxed WASM Tool execution;
+- Plugin permission grant enforcement;
+- follow-up Tickets for read-only inspection CLI, `https`, `fs`, and Component Model migration.
+
+The remaining work must be kept as one roadmap because the pieces constrain each other:
+
+- Plugin authoring needs an SDK/PDK and examples, not raw pointer/length Wasm ABI hand-coding.
+- `https` and `fs` host APIs must be grant-gated and shaped so they can move cleanly to typed Component Model interfaces.
+- Diagnostics (`yoi plugin list/show`) are needed before the system becomes harder to debug.
+- Component Model adoption should guide new host API design before a custom raw ABI becomes entrenched.
+- Service / Ingress are useful for bridge-style integrations, but should come after Tool runtime, diagnostics, and host API policy are stable.
+
+Research of common Wasm extension systems points to the same pattern: mature systems combine a package manifest, explicit capabilities, a sandbox runtime, host-provided capability APIs, language SDK/PDK bindings, templates/examples, inspection/check tooling, and versioned interfaces.
+
+## Strategy / design direction
+
+- Keep Plugin as a user-facing package/config/runtime layer above lower-level `pod::feature` substrate.
+  - `pod::feature` provides contribution/registration substrate.
+  - Plugin owns package discovery, enablement, grant policy, runtime selection, authoring UX, and user-facing diagnostics.
+- Preserve authority boundaries.
+  - Package discovery is read-only inventory.
+  - Package presence never registers a Tool/Hook, executes Wasm, starts a Service, reads files, opens network, or injects context.
+  - Explicit enablement and Plugin grants are required before registration/execution/host API use.
+  - Tool calls/results continue through ordinary ToolRegistry and Worker history paths.
+- Treat Component Model as the active Plugin runtime shape before public release.
+  - New typed Plugin host APIs should be designed in WIT-compatible terms.
+  - `runtime.kind = "wasm-component"` is the current Plugin runtime authority for new work.
+  - The earlier `yoi-plugin-wasm-1` raw core-Wasm compatibility bridge is retired from the active roadmap because Plugin has not been publicly released and compatibility would preserve the wrong boundary.
+- Sequence the platform in usable layers:
+  1. Package discovery / explicit enablement / digest-pinned restore. Completed foundation.
+  2. Tool surface registration. Completed foundation.
+  3. Minimal WASM Tool execution. Completed foundation.
+  4. Permission grants. Completed foundation.
+  5. Read-only Plugin CLI inspection (`yoi plugin list/show`) for debugging discovery/enablement/grants/runtime metadata.
+  6. `https` and `fs` host APIs for Tool Plugins, grant-gated and WIT-compatible.
+  7. Remove the raw core-Wasm compatibility bridge and reject legacy runtime manifests.
+  8. Component Model runtime and authoring model become the only active Plugin runtime path.
+  9. Guest SDK/PDK, examples, `check`/`pack`/`new` authoring tooling target Component Model only.
+  10. Service / Ingress runtime is developed as host-managed lifecycle, event queue, output command, and diagnostics slices.
+  11. WebSocket support for long-lived integrations is host-owned connection driver + ingress event delivery + output command, not Plugin-owned polling with `recv(timeout)`.
+- Keep Discord-style bridge goals split into two stages.
+  - Outbound Discord/webhook Tool is possible after `https`.
+  - Bidirectional Discord bridge requires Service + Ingress + WebSocket or inbound HTTP and host routing policy.
+
+## Current implementation split
+
+The broad Plugin runtime redesign is tracked by `00001KVXHVCR5` as context only; implementation should proceed through concrete Tickets instead of routing that umbrella as a single coding task.
+
+1. `00001KVXK0WD3` Remove legacy raw WASM Plugin runtime.
+   - Deletes the active `LegacyToolAdapter` / raw-Wasm execution path.
+2. `00001KVXK0WDH` Reject legacy Plugin runtime in manifest and CLI diagnostics.
+   - Makes `plugin.toml`, `yoi plugin check/list/show`, docs, and fixtures reflect Component Model only runtime authority.
+3. `00001KVXK0WDQ` Define Plugin Service lifecycle and ingress queue runtime.
+   - Adds host-managed lifecycle, bounded queue, serial dispatch, backpressure, timeout, and diagnostics.
+4. `00001KVXK0WDX` Add Plugin service output command model.
+   - Lets service handlers request side effects as grant-checked commands rather than ambient authority.
+5. `00001KVXK0WE4` Add host-owned WebSocket driver for Plugin services.
+   - Converts incoming WS frames into ingress events and sends outbound frames through output commands.
+6. `00001KVXK0WEA` Update Plugin WIT PDK templates for service event runtime.
+   - Aligns authoring API, WIT, PDK, templates, and docs with the new event/command execution model.
+
+## Success criteria / exit conditions
+
+- Users can inspect Plugin discovery/enablement/grant/runtime state through a read-only CLI without executing Plugin code.
+- Plugin authors can build a Tool Plugin without writing raw memory/pointer ABI plumbing.
+- Tool Plugins can safely call grant-gated `https` and `fs` host APIs.
+- Component Model is the only active Plugin runtime path, with WIT-compatible host API types and measured packaging/runtime impact.
+- Plugin grants remain authoritative over registration, execution, and host API calls.
+- Plugin diagnostics explain missing package, invalid manifest, digest/version mismatch, missing grant, rejected schema, runtime mismatch, legacy runtime rejection, and unsupported host API cases safely.
+- Raw core-Wasm Plugin compatibility is removed before public release; tests and docs no longer treat it as a current runtime.
+- Documentation covers package format, Component Model runtime, host API authority, authoring SDK/templates, Service/Ingress event runtime, and operational debugging.
+- Service/Ingress work is host-managed: services have lifecycle/status, ingress uses bounded queues, side effects are output commands, and WebSocket integrations use host-owned connection drivers.
+
+## Decision context
+
+- This Objective is roadmap context, not Ticket authority. Implementation still requires reading concrete Ticket bodies, threads, artifacts, and relations.
+- Component Model direction supersedes Yoi's custom raw ABI as both long-term and current active Plugin runtime authority before public release.
+- `https` / `fs` work should avoid choices that conflict with later WIT typed interfaces.
+- Guest SDK work targets Component Model directly; raw ABI wrappers are not a supported transitional authoring path.
+- Plugin and MCP remain separate. Component Model adoption for Plugin does not imply MCP server execution, MCP prompt/resource injection, or MCP trust policy changes.
+- Plugin surfaces remain Tool / Hook / Service / Ingress; outbound side effects are Tool metadata and host API grants, not a separate surface.

+
+## Goal
+
+Yoi を、単一のローカル開発ディレクトリで動くエージェント実行ツールから、チームで作業・判断・実行結果を管理できるワークスペース基盤へ発展させる。
+
+この Objective の中心は、Web から扱える管理システムを作り、その管理システムにローカル実行環境・リモート実行環境・将来のクラウド実行環境を接続できるようにすることである。管理システムは Ticket、Objective、Memory、Knowledge、Run、Artifact、Runner の正本を持つ。実行環境はその管理システムから仕事を受け取り、コード取得、作業用ディレクトリ作成、エージェント実行、検証、結果報告を行う。
+
+この Objective は Git ホスティングサービスを作るものではない。Git は重要な Repository provider として扱うが、Yoi の Workspace は Git Repository root と同じものにしない。Yoi が作るべきものは、コード・ドキュメント・データ・成果物などの Repository と実行環境を接続しながら、人間とエージェントの作業、Ticket lifecycle、Memory/Knowledge、検証証跡、実行環境配置を管理するチームワークスペースである。
+
+## Glossary
+
+この Objective では、以下の語をこの意味で使う。
+
+- Workspace: チームまたはプロジェクトの管理単位。Ticket、Objective、Memory、Knowledge、Run、Artifact、Policy、Actor、Repository を持つ。Git Repository root ではない。
+- Control plane: Workspace の正本を持ち、Web UI / API / CLI から操作される管理システム。
+- Runner: Control plane から仕事を受け取り、実際にエージェントやツールを動かす実行環境。最初はローカルマシン上の runner、後でリモート runner やクラウド runner を追加する。
+- Repository: Workspace に接続される source/storage。コード、ドキュメント、local directory、object storage、artifact store、dataset などを含む。Git Repository も Repository の一種であり、基本的には filesystem path ではなく URI / URL で識別する。
+- Repository provider: Repository の種類ごとの実装。Git、local filesystem、object store、artifact store、将来の non-Git VCS など。
+- RepositoryPoint: Repository 内の特定地点。Git commit/ref/path、object store version/prefix、file snapshot/path など、provider ごとの revision/ref/snapshot/path を表す。
+- Execution Workspace: Runner が Run のために作る作業用ディレクトリや container filesystem。1 つ以上の RepositoryPoint から materialize される。Git worktree、clone、sparse checkout などはこれを作る手段である。
+- Ticket: チームで扱う作業単位。目的、要件、判断、議論、完了条件、関係、証跡を持つ。
+- Objective: 複数の Ticket を束ねる長期目標や設計方針。
+- Run: Ticket や Objective に対して行われた具体的な実行試行。どの Runner が、どの Execution Workspace で、何を実行し、どんな結果になったかを持つ。
+- Artifact: Run や Ticket に紐づく成果物や証跡。diff、log、validation result、review result、report など。
+- Memory: エージェントやユーザーが再利用するための要約された文脈。Ticket や Run の正本ではない。
+- Knowledge: 保守された知識や設計判断。Memory より人間が維持する資料に近い。
+- Actor: 人間、エージェント、システム、外部サービスなど、Workspace 上で操作や発言を行う主体。
+
+## Motivation / background
+
+現在の Yoi は、ローカルの `.yoi` ディレクトリ、ローカルプロセス、Ticket ファイル、ワークツリー運用によって、自分自身の開発に使えるエージェント実行環境になっている。しかし、チーム利用、Web UI、リモート実行、クラウド実行、最終的な SaaS 提供を考えると、次の前提を変える必要がある。
+
+- Workspace を Git Repository root と同一視しない。
+- ローカル filesystem 上の `.yoi` を、長期的なチーム用正本 store にしない。
+- Ticket をローカル作業メモではなく、チームの作業調整 record にする。
+- Ticket と実行試行を分ける。実行試行は Run として記録する。
+- 管理システムと実行環境を分ける。
+- まず Web から Ticket、Objective、Memory、Knowledge、Run、Artifact、Runner state を見られるようにする。
+- 最初はローカルマシンを Runner として使い、後でリモート Runner、クラウド Runner、runner pool、resource allocation、quota、billing、sandboxing に拡張する。
+- Git ホスティング機能を取り込むのではなく、Git Repository / worktree / clone は Repository provider と Execution Workspace materialization の手段として扱う。
+
+OSS として Control plane、Runner、Web frontend、protocol を公開しつつ、managed service では hosted control plane、runner fleet、リソース柔軟性、team auth、backup、audit、availability、multi-tenant operations で価値を出す。
+
+## Strategy / design direction
+
+### 1. Control plane を先に作る
+
+Team Workspace の正本は server-side control plane に置く。`.yoi` は local backend、single-user/self-hosted compatibility、offline/export/import、runner-local projection、migration bridge として残せるが、multi-user SaaS の正本とはみなさない。
+
+Control plane は Ticket、Objective、Memory、Knowledge、Run、Artifact、Actor、Permission、Audit、Runner state を管理する。Web UI、CLI、TUI、将来の desktop client は、この Control plane を操作する client であり、別の正本 store を持たない。
+
+### 2. Workspace と Repository を同一視しない
+
+Workspace はチームまたはプロジェクトの作業管理単位である。Repository は Workspace に接続される source/storage である。Git Repository は Repository の一種にすぎない。
+
+1 つの Workspace は複数の Repository を持てる。Repository は filesystem path ではなく URI / URL で識別する。例として `git+https://...`、`file://...`、`s3://...`、`artifact://...`、将来の VCS provider URI などを扱えるようにする。
+
+Ticket と Objective は Repository 配下に置かず、Workspace 配下に平たく持つ。Ticket は必要に応じて対象 Repository、ref selector、path、必要 capability を持つ。Objective は複数 Ticket にまたがる target default / scope hint を持てるが、Repository の所有物にはしない。
+
+Run は Ticket の target selector を具体的な RepositoryPoint に解決し、その RepositoryPoint から Execution Workspace を materialize する。Git worktree 相当の機能は、この Execution Workspace を作るための実装戦略として扱う。
+
+短期的には Git を主な Repository provider とする。ただし Yoi の authority model を Git object、Git branch、Git Repository root、worktree path に固定しない。Orchestration は Git そのものではなく、`resolve_ref`、`materialize`、`diff`、`patch`、`commit`、`merge` などの Repository capability に依存する。
+
+### 3. Ticket を team coordination record にする
+
+Ticket は実行そのものではない。Ticket は「何を、なぜ、どの条件で完了とみなすか」を持つ。Ticket は Workspace に平たく所属し、Repository には所属しない。コードやドキュメントを対象にする Ticket は、対象 Repository / ref selector / path / intent を target として持つ。
+
+Ticket target は intent/selector であり、実行再現性のための immutable point ではない。Run が target selector を concrete RepositoryPoint に解決し、実際にどの revision/snapshot を materialize したかを記録する。
+
+```text
+Ticket
+  -> target selectors: Repository + ref selector + path + intent
+  -> Run / Attempt
+  -> resolved RepositoryPoint
+  -> Execution Workspace
+  -> Artifact / Evidence
+  -> Review / Decision
+  -> Audit / Notification
+```
+
+Target 例:
+
+```text
+Ticket targets:
+  - repository: main-code
+    role: primary
+    ref: develop
+    paths: ["crates/pod/"]
+    intent: change
+  - repository: docs
+    role: related
+    ref: main
+    paths: ["docs/development/"]
+    intent: read
+
+Run inputs:
+  - repository: main-code
+    requested_ref: develop
+    resolved_point: git commit abc123
+    mount: /workspace/main-code
+```
+
+Ticket には次の概念が必要になる。
+
+- Actor identity: human / agent / system / service account.
+- Assignment / owner / reviewer / watcher.
+- Typed thread events: comment, decision, plan, review, implementation report, state transition.
+- Linked Objective / Artifact / Run / Repository / RepositoryPoint / Execution Workspace.
+- Permission / visibility.
+- Audit trail.
+- Notification / mention.
+- Board / queue / planning / review / done / archived views.
+- Conflict handling and concurrent editing policy.
+
+### 4. Memory / Knowledge の本格再設計は後回しにする
+
+Memory / Knowledge は Ticket / Run / Artifact のコピーではない。再利用可能な文脈、方針、学習された制約、保守された知識として扱う。ただし、Memory の意味論・抽出・承認・検索・staleness 処理を今この Objective で先に作り込まない。
+
+理由は、Memory の正しい設計が Workspace control plane の record model、Actor / visibility / permission、Ticket と Run の分離、Artifact / evidence、RepositoryPoint、Runner に渡す context の監査方法に依存するためである。これらが固まる前に Memory schema だけを作ると、local `.yoi` 前提や現行 agent runtime 前提に引っ張られ、後で再設計が必要になる。
+
+この Objective では、Memory / Knowledge について以下の platform contract だけを維持する。
+
+- Memory / Knowledge は Control plane が扱う record だが、Ticket / Run / Artifact の authority を置き換えない。
+- 将来、Memory / Knowledge の canonical storage は Workspace control plane 側に置く。
+- local `.yoi` memory は compatibility、offline/export/import、runner-local projection、migration bridge として扱う。
+- Personal Memory、Workspace Memory、Run Summary、Maintained Knowledge は分離が必要である。
+- Generated Memory には provenance、visibility、approval、audit が必要である。
+- Runner / agent に渡した Memory/Knowledge context は、将来 ContextPack などとして Run に記録できる必要がある。
+
+本格的な Memory 再設計は、Memory の保存先を Workspace backend / control plane record に移すタイミングで回収する。それまでは低リスクな観察、問題例の収集、既存 local memory の互換維持に留める。
+
+### 5. 管理システムと実行環境を弱結合にする
+
+Control plane は正本と調整を持つ。Runner は実行を担当する。
+
+初期形:
+
+```text
+Web UI / Control Plane
+  -> Runner connection
+  -> Local machine runner
+  -> Existing Yoi runtime, tools, working copy, build/test commands
+```
+
+この段階では、現在ローカル管理画面が行っている Ticket 選択、エージェント起動、レビュー起動、作業用 checkout 作成、検証実行、結果表示を、Web/control plane から local runner に対して実行できるようにする。
+
+その後で、remote runner、self-hosted runner、hosted cloud runner、runner pool、resource allocation、quota、billing、sandbox、network policy、secret distribution を追加する。
+
+```text
+Phase 1: Web control plane + local runner
+Phase 2: Remote/self-hosted runner
+Phase 3: Hosted cloud runner fleet
+Phase 4: Resource allocation / scheduling / quotas / billing / isolation
+```
+
+### 6. Web frontend を先に作る
+
+Desktop app は対応コストが高いので、まず Web frontend を primary UI とする。
+
+- Web: チームで使う主要 UI。
+- CLI: automation、scripting、local operations。
+- TUI/local panel: local runner cockpit、fallback、dogfooding surface。
+- Future desktop: Web/control-plane model が安定した後に検討する optional client。
+
+Web UI は Ticket、Objective、Memory、Knowledge、Run、Runner、Artifact を扱う。UI の都合で正本を二重化しない。
+
+### 7. 多重起動コストと runtime placement を見直す
+
+Cloud/remote execution を成立させるには、多数のエージェント実行を安く管理できる必要がある。logical agent session と runtime process/resource placement を分ける。
+
+初期 Workspace DB では、Worker を canonical table として永続化しない。Host / Worker 一覧は backend-local runtime inspection や将来の Host protocol から逐次取得する live view とし、Ticket に関わった Worker は Ticket thread events と WorkerRef snapshot / TicketWorkerLink として記録する。
+
+Worker の一元管理、データ永続化、アーカイブは将来的には必要になる。これは Host protocol、remote/self-hosted/hosted worker lifecycle、worker identity、retention policy、audit requirements が固まった後に、dedicated Worker registry / archive model として追加する。v0 で Pod metadata の代替として Worker table を作らない。
+
+検討対象:
+
+- Agent identity と process/runtime placement の分離。
+- Provider client、tool registry、resource cache の共有可能性。
+- Prompt/resource/profile resolution cache。
+- Model call multiplexing and scheduling。
+- Tool execution sandbox reuse。
+- Plugin instance / Service runtime との統合。
+- Session/event stream と runtime lifecycle の分離。
+- Runner-local cache、checkout reuse、build cache、dependency cache。
+
+## Initial phases / candidate tickets
+
+1. **Vocabulary / architecture record**
+   - Workspace / Repository / RepositoryPoint / Execution Workspace / Runner / Control Plane / Run / Ticket / Memory / Knowledge の用語と境界を固める。
+2. **Team-space canonical data model**
+   - Ticket / Objective / Target / Run / Artifact / Actor / Permission / Audit / Memory / Knowledge の entity/event model を設計する。
+3. **Ticket and Run separation**
+   - Ticket lifecycle と execution attempt / orchestration run / validation run を分離し、Ticket thread と Run evidence の責務を明確化する。
+4. **Memory storage migration boundary**
+   - Memory / Knowledge の本格再設計は後回しにし、まずは Workspace backend に移す時の platform contract、compatibility/cache/export 方針、将来の provenance / visibility / approval 要件だけを固定する。
+5. **Control plane backend architecture**
+   - local `.yoi` backend と server-side canonical backend の境界、migration/export/import、compatibility mode を設計する。
+6. **Web control plane MVP design**
+   - read-only Ticket / Objective / Memory / Knowledge / Runner state UI/API の範囲を決める。
+7. **Local runner protocol design**
+   - Web/control plane から local runner に安全な操作を送る protocol と authority boundary を設計する。
+8. **Repository and Execution Workspace materialization model**
+   - Repository URI、Repository provider capability、RepositoryPoint resolution、Git worktree / clone / sparse checkout / future source backend を runner-side strategy として抽象化する。
+9. **Remote/hosted runner foundation**
+   - runner registration, heartbeat, capability advertisement, job assignment, logs/events, secrets, sandbox/resource policy を設計する。
+
+## Non-goals
+
+- Git hosting service を作ること。
+- `.yoi` filesystem をそのまま SaaS canonical store にすること。
+- 最初から full hosted cloud execution を作ること。
+- local execution / CLI / TUI / local panel を捨てること。
+- Ticket を単なる issue tracker clone にすること。
+- Memory を Ticket/Run audit log の代替にすること。
+- Web UI のために core authority を二重化すること。
+- hidden server state を LLM context に直接注入すること。
+- multi-tenant auth/billing/secret/security を shortcut して実装すること。
+
+## Success criteria / exit conditions
+
+- Workspace / Repository / RepositoryPoint / Execution Workspace / Runner / Control Plane / Run / Ticket / Memory / Knowledge の境界が文書化されている。
+- Ticket が team coordination record として、target selector / Run / Artifact / Actor / Permission / Audit と分離された model を持つ。
+- `.yoi` local backend は compatibility/local backend として整理され、server-side canonical backend の設計を阻害しない。
+- Web UI/API が Ticket / Objective / Runner state を中心とした read-only view を提供できる設計または MVP を持つ。Memory / Knowledge は既存 record の表示または将来 placeholder に留め、本格再設計をこの段階の必須条件にしない。
+- Control plane から local runner に対して、現在のローカル管理画面相当の安全な操作を実行できる design/protocol がある。
+- Git Repository root に依存しない Workspace model があり、Git Repository は Repository provider の一種として扱われている。
+- Ticket と Objective は Workspace 配下に平たく存在し、Repository への所属ではなく target selector / scope hint で対象を表現する。
+- Git worktree 相当は Execution Workspace materialization strategy として扱われ、Run が immutable な RepositoryPoint を記録する。
+- Memory / Knowledge は Ticket / Run / Artifact の authority を置き換えない record として platform contract だけを持つ。本格的な意味論・抽出・承認・検索・staleness 処理は、Memory の保存先を Workspace backend / control plane record に移すタイミングで回収する。
+- Hosted runner / resource allocation / SaaS offering に進むための後続 Ticket が切れる状態になっている。
+- 既存 local dogfooding runtime を壊さず、local use と remote-capable architecture が両立している。
+
+## Decision context
+
+- Yoi は hosted Git tool ではなく、team workspace control plane + execution environment として設計する。
+- Team-space の長期 canonical authority は server-side control plane に置く。local `.yoi` は互換/local/offline/export/import surface だが、multi-user SaaS の正本ではない。
+- 実行環境と管理システムは弱結合にする。まず管理システムを独立させ、local runner を実行環境として接続する。その後に remote/self-hosted/hosted runner fleet へ進む。
+- Web frontend を最初の primary team UI とする。Desktop app は web/control-plane model が安定した後に検討する。
+- Git は重要な Repository provider / materialization backend として使うが、Workspace identity と authority を Git Repository root に固定しない。
+- Ticket と Objective は Workspace 配下に平たく持つ。対象コードベースや ref は Repository target selector として表現し、Run が concrete RepositoryPoint に解決する。
+- Memory の本格再設計は後回しにする。先に Workspace / Ticket / Repository / Host/Worker live view / Control plane の基盤を固め、Memory の保存先を Workspace backend に移すタイミングで、意味論・抽出・承認・検索・staleness 処理をまとめて回収する。
+- Worker の一元管理・データ永続化・アーカイブも後続設計に回す。初期 DB では Worker を Pod metadata の代替として永続化せず、live view と Ticket-linked WorkerRef 記録に留める。

+
+## Goal
+
+Yoi の Memory / Knowledge / generated memory / resident context / retrieval / usage metrics を、実際の開発・設計・レビュー・オーケストレーションに効く sensemaking substrate として再設計・検証する。
+
+この Objective でいう「効果的な Memory システム」は、単に多く保存する仕組みではなく、作業中の問いに対して relevant material を集め、根拠を検証可能にし、再表現・仮説形成・反証探索・意思決定・成果物への反映を低コストにする仕組みである。
+
+暫定的な定義:
+
+- foraging cost を下げる: Ticket / Objective / current question に対して、関連する memory / docs / tickets / session evidence / code references を探しやすい。
+- evidence を失わない: Memory が authority そのものにならず、Ticket / docs / git history / session logs / user instruction への検証可能な入口になる。
+- schema 化を支援する: raw summary ではなく、subsystem、invariant、risk、authority boundary、open question、rejected alternative、hypothesis など推論しやすい形へ再表現できる。
+- hypothesis loop を支援する: 支持証拠だけでなく、代替仮説・棄却理由・反証 evidence・stale assumption を扱える。
+- product に戻る: Memory に保存して終わりではなく、Ticket、review、docs、implementation、decision、report に影響を戻せる。
+- stale / contradiction を扱う: 古い前提、矛盾、適用範囲外の memory を検出・降格・更新できる。
+- usage を成果基準で測る: resident exposure や read count ではなく、判断・レビュー・実装・docs に効いたかを観測できる。
+
+## Motivation / background
+
+現在の Memory システムは「墓場化」している。保存された情報はあるが、後続の作業で自然に使われにくく、使われたとしても根拠・適用範囲・鮮度・反証可能性が弱い。結果として Memory は、作業場ではなく古い結論の倉庫になりやすい。
+
+Pirolli & Card 2005 の sensemaking model では、分析作業は単なる保存ではなく、次の変換として捉えられる。
+
+```text
+external data sources
+-> shoebox
+-> evidence file
+-> schema / representation
+-> hypotheses
+-> presentation / product
+```
+
+Yoi の現行 Memory は、この流れのうち「保存」と「一部の検索」には対応しているが、少なくとも以下が弱い。
+
+- Ticket / task / question ごとの shoebox がない。
+- shoebox から evidence snippets を切り出し、source / provenance / applicability / confidence と共に扱う evidence file がない。
+- `summary`, `decision`, `request`, `knowledge` は storage taxonomy であり、sensemaking 用 schema としては粗い。
+- decision は残るが、hypothesis space、alternative、rejected reason、disconfirming evidence が残りにくい。
+- reviewer / orchestrator が confirmation bias を避けるための反証探索導線が弱い。
+- resident exposure と explicit retrieval は観測できても、Memory が product に効いたかは測りにくい。
+
+この Objective は、Memory 関連の設計・検証・検討・考察を一元化し、個別 Ticket がばらばらに storage、prompt、retrieval、metrics を改善して再び墓場を増やすことを防ぐための判断背景である。
+
+## Strategy / design direction
+
+Memory を「長期保存領域」ではなく、Yoi の multi-agent 開発における sensemaking loop の支援機構として設計する。
+
+### 1. Pirolli & Card の stage に合わせて責務を分ける
+
+- external data sources: Tickets、docs、git history、session logs、reports、code、user instructions。
+- shoebox: 特定 Ticket / Objective / design question に対して関連しそうな材料を集めた task-bound working set。
+- evidence file: shoebox から抜き出した根拠 snippet。source anchor、支持/反証、適用範囲、confidence、staleness を持つ。
+- schema / representation: subsystem、invariant、risk、authority boundary、open question、hypothesis、alternative、contradiction など、推論しやすい再表現。
+- hypotheses: 採用前の設計仮説、代替案、棄却条件、反証 evidence。
+- product: Ticket、review、docs、implementation、decision、report、orchestration plan などの成果物。
+
+### 2. 最初の重点は task-bound shoebox と evidence file
+
+Memory 墓場化の最初の原因は、保存情報が現在の問いに集まらないことである。まずは Orchestrator / Intake / Reviewer が Ticket を扱う時に、関連 memory / docs / tickets / reports / prior decisions を shoebox として束ねる導線を作る。
+
+この段階では大きな永続 schema 追加に飛びつかず、report / Ticket artifact / bounded generated context として検証してよい。
+
+### 3. Memory を authority にしない
+
+Memory は Ticket、docs、git history、session logs、user instruction の代替ではない。Memory は authority record への evidence index / schema / reasoning aid として扱う。
+
+したがって、改善案は次の性質を持つべきである。
+
+- source / provenance を辿れる。
+- stale / superseded / contradicted を扱える。
+- Memory の断定をそのまま authority として使わない。
+- Ticket body/thread/artifacts を読まずに Objective や Memory だけで実装判断できる状態を作らない。
+
+### 4. 反証探索を first-class にする
+
+より効果的な Memory は、過去方針を思い出すだけでなく、現在案を疑うために使える必要がある。
+
+Reviewer / Orchestrator / Intake の導線では、次を探せるようにする。
+
+- supporting evidence
+- contradicting evidence
+- stale decisions
+- rejected alternatives
+- unresolved questions
+- authority boundary risks
+- prior failures / reports
+
+### 5. Metrics は exposure から product impact へ寄せる
+
+Memory が prompt に入った、または query されたことは成功ではない。評価は次を区別する。
+
+- resident exposure
+- explicit retrieval
+- cited in response
+- cited in Ticket / review / report
+- changed requirement
+- changed implementation
+- contradicted / invalidated
+- led to docs or decision update
+
+### 6. 後続 Ticket は concrete slice に分割する
+
+この Objective は中期的な設計・検証の一元化 record であり、umbrella Ticket ではない。実装や調査は、単独で実装・レビュー・close できる concrete Ticket に分割する。
+
+候補 slice:
+
+- Memory sensemaking 分析 report を `docs/report/` に作る。
+- Ticket routing 用 Memory shoebox artifact を試作する。
+- evidence snippet schema / source resolver を設計する。
+- hypothesis / rejected alternative / disconfirming evidence の表現を追加する。
+- Reviewer workflow に反証探索を入れる。
+- Memory usage metrics を product impact oriented に拡張する。
+- stale / contradiction / renewal の検出・表示を設計する。
+
+## Success criteria / exit conditions
+
+- Memory システムの目的が「保存」ではなく「sensemaking loop 支援」として project records / docs / prompts / workflows で一貫して説明されている。
+- Pirolli & Card の `shoebox -> evidence file -> schema -> hypotheses -> product` に対応する Yoi 内の責務と非責務が整理されている。
+- Ticket / Objective / docs / session logs / Memory / Knowledge の authority boundary が明確で、Memory が authority を僭称しない。
+- 少なくとも一つの実作業 routing / review / design analysis で、task-bound shoebox または evidence file が生成・利用され、作業品質にどう効いたかが確認されている。
+- Memory records または関連 artifacts が source / provenance / applicability / staleness / supports-or-refutes のいずれかを扱えるようになっている。
+- Reviewer / Orchestrator が supporting evidence だけでなく、contradicting evidence / stale assumptions / rejected alternatives を探す導線を持っている。
+- Memory usage metrics が resident exposure と product impact を区別している。
+- 古い Memory が放置されるのではなく、stale / superseded / contradicted / needs-review として扱える方針がある。
+- 後続の実装 Ticket が concrete slice として分割され、Objective が Ticket dependency や進捗 container として使われていない。
+
+この Objective は、Memory が少なくとも一つの中規模設計・実装・レビュー作業で「関連情報を見つける」「根拠を確認する」「代替案/反証を検討する」「成果物へ反映する」流れを実証し、その設計方針が docs / workflows / metrics に反映された時点で `done` を検討できる。
+
+## Decision context
+
+- ユーザー指摘: 「Memoryシステムが完全に墓場化している」。これは保存量不足ではなく、保存情報が現在の問い・根拠・仮説・成果物に接続されない問題として扱う。
+- ユーザー指示: Memory システムの設計・検証・検討・考察を Objective にまとめ、より効果的な Memory システムを作成する目標のもとで情報を一元化する。
+- 「効果的」の定義は未確定だが、当面は Pirolli & Card の sensemaking process に沿って、foraging cost、evidence quality、schema usefulness、hypothesis/disconfirmation support、product impact、staleness handling を評価軸にする。
+- Memory は durable project authority ではない。Ticket、docs、git history、session logs、明示 user instruction の代替として使わない。
+- Objective context は判断背景であり、個別実装の authority は各 Ticket body/thread/artifacts と明示的な Ticket relations / OrchestrationPlan records にある。
+- `history` に残らない context-only injection を改善案にしない。新しい context input は history に commit する原則を守る。
+- Knowledge は単なる長期保存ではなく、再利用可能な schema / model / procedure / invariant として再検討する余地がある。
+- Generated memory / curated Knowledge / Ticket / docs / report の境界を再定義する場合は、authority boundary と migration/staleness を明示する。
+- 関連する既存 Ticket:
+  - `00001KSKBPHRG` — Prompt / Workflow 評価メトリクスと改善 Offer
+  - `00001KT02TCCG` — Memory prompt: conditional guidance and proactive lookup
+  - `00001KTGCAFXG` — Use .yoi/memory marker for repo-local memory root
+  - `00001KSKBPTHR` — ワークスペースのメモリーをLintするヘッドレスCLI
+
+## Historical references / prior design sources
+
+現在の Memory システムの初期設計時には、Codex Memories / Chronicle と HermesAgent を明示的な参考事例として調査していた。関連する調査・設計記録は、現在は主に以下に退避されている。
+
+- `docs/.local/old-docs/ref/memory-systems.md`
+- `docs/.local/old-docs/plan/memory.md`
+- 初期設計 commit: `ca5a3d11` — `2026-04-21 メモリシステムの設計`
+- 関連 commit:
+  - `0c1276b7` — `Memoryシステムの整理・Promptカタログチケット`
+  - `3d04f793` — `memoryを抽出する仕組みの実装`
+  - `f1b7af62` — `docs: memoryシステムの仕様変更と、動的Tool・VCSの話`
+  - `a2aecbf0` — `update: memoryシステムの"Phase"表記を撤廃`
+
+### Codex Memories / Chronicle から得た設計要素
+
+旧設計では、Codex Memories / Chronicle を `extract -> staging -> consolidation -> durable Markdown memory` の非同期パイプラインとして捉えていた。
+
+主な参照点:
+
+- extract と consolidation の 2 段構成。
+- extract は JSON schema / structured output で分類ブレを抑える。
+- consolidation は reasoning model / agentic rewrite によって、既存 memory と staging entries を統合・整理する。
+- staging と durable memory を分ける。
+- `MEMORY.md` は retrieval-oriented handbook として扱う。
+- `memory_summary.md` は prompt-loaded high-signal context として扱う。
+- `raw_memories.md` は routing layer / task inventory 的な中間層として扱う。
+- workspace diff や usage 情報を使い、stale / deleted evidence / noisy entries を整理する。
+- consolidation は append だけでなく、rewrite / merge / split / trim / drop / cleanup を担う。
+
+Yoi 初期設計では、これを参考に以下を意図していた。
+
+- activity token 閾値で extract を発火する。
+- compact より前に session log range を抽出する。
+- extract は `decisions`, `discussions`, `attempts`, `requests` などの候補を staging に保存する。
+- 抽出時点では Knowledge 化せず、純粋な「起きたこと」に寄せる。
+- consolidation が summary / decisions / requests / knowledge candidates を整理する。
+- consolidation 入力に linter warnings / usage metrics / Knowledge 化候補を含める。
+- stale / superseded / unused / noisy な情報を整理する。
+
+この Objective での再解釈:
+
+- Codex の `raw_memories.md` は、Pirolli & Card の sensemaking model では `shoebox` または `evidence file` に近い。
+- Yoi は extract / consolidation という pipeline だけを継承しても不十分であり、task-bound shoebox / evidence file / hypothesis loop / product feedback がなければ Memory は再び墓場化する。
+- 特に、staging を consolidation の一時入力としてだけ扱うと、後続 Ticket / Objective / review が使う探索入口にならない。
+- Yoi では `raw memories` 相当の中間層を、現在の問いに紐づく working set / evidence index として再設計する必要がある。
+
+### HermesAgent から得た設計要素
+
+旧設計では、Nous Research HermesAgent を 3 層の memory system として整理していた。
+
+- Persistent Memory:
+  - `MEMORY.md` / `USER.md`
+  - Markdown + SQLite / FTS5 session search
+  - 起動時 system prompt snapshot
+  - bounded character limits
+- Skill Library:
+  - procedural memory
+  - `~/.hermes/skills/<name>/SKILL.md`
+  - `skill_manage` tool による agentic CRUD
+- User Model / Honcho:
+  - dialectic user modeling
+  - 外部 service 連携
+
+HermesAgent で特に重要だった点:
+
+- memory / skill review は一定 turn / tool iteration ごとに background agent として起動する。
+- 保存すべきものがなければ `Nothing to save.` で NOP として終了する。
+- Yoi extract の「空配列許容」はこの設計からも影響を受けている。
+- memory は session start 時の frozen snapshot として system prompt に入り、mid-session write で prompt cache を壊さない。
+- persistent memory は bounded で、limit 超過時は deterministic eviction ではなく、agent に replace / remove を促す。
+- procedural memory / skills は一般 memory から分離されている。
+- SQLite FTS5 + LLM summarization による cross-session recall がある。
+
+この Objective での再解釈:
+
+- HermesAgent の `MEMORY.md` / `USER.md` / `skills` の分離は、Yoi の Knowledge / Workflow / prompt resource / docs / Ticket decision / generated memory の責務再整理に使える。
+- reusable procedure, reviewer focus, orchestration tactic, project preference, user preference, design invariant を同じ Memory bucket に入れると墓場化しやすい。
+- `Nothing to save.` / empty extraction allowed は重要だが、保存抑制だけでは効果的な Memory にはならない。保存されたものが task-bound shoebox / evidence / schema / hypothesis / product に接続される必要がある。
+- frozen snapshot / prompt cache 配慮は Yoi の history/context 加工原則と整合するが、それだけでは retrieval / resurfacing / disconfirmation は解決しない。
+
+### Lessons for the next design iteration
+
+Codex と HermesAgent の調査から、Yoi が継承すべきものと、継承するだけでは足りないものを分ける。
+
+継承すべきもの:
+
+- structured extract と agentic consolidation の分離。
+- staging / raw memories / durable memory の分離。
+- 保存対象がなければ NOP にする発火設計。
+- prompt-loaded summary と durable retrieval-oriented memory の分離。
+- stale / noisy / unused entries の cleanup。
+- procedural memory と declarative memory の分離。
+- session search / usage metrics / linter feedback を consolidation に入れる設計。
+
+足りないもの:
+
+- Pirolli & Card の sensemaking stage における各 record の役割定義。
+- Ticket / Objective / current question に紐づく task-bound shoebox。
+- authority record へ戻れる evidence file / provenance / source anchor。
+- hypothesis, alternative hypothesis, rejected reason, disconfirming evidence の first-class 表現。
+- reviewer / orchestrator が confirmation bias を避けるための反証探索導線。
+- resident exposure や read count ではなく product impact を測る metrics。
+- stale / contradiction / renewal を作業中に resurfacing する導線。
+
+したがって、次の Memory 設計は Codex / HermesAgent の単純なコピーではなく、以下を満たす必要がある。
+
+```text
+external data / sessions / tickets / docs / code
+-> task-bound shoebox
+-> evidence file with provenance
+-> schema / representation
+-> hypotheses and disconfirmation
+-> Ticket / review / docs / implementation / decision product
+-> product impact and stale-feedback metrics
+```
+
+この Objective では、以後の Memory 関連 Ticket / report / implementation をこの historical reference と sensemaking model の両方に照らして判断する。

+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.
+

+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。
+
+Validation:
+- focused E2E harness tests / example scenarios。
+- `cargo fmt --check`。
+- `git diff --check`。
+- 変更範囲に応じて `cargo check --workspace --all-targets` または narrower package checks。
+- 新 E2E command が opt-in で実行可能であることを report する。
+
+Current code map:
+- `crates/yoi` / CLI launch path: hidden/test-only flag injection の候補。
+- `crates/tui/src/multi_pod.rs`: Panel events / observable state emission の候補。
+- `tests/e2e/` or new harness crate: declarative scenario API / PTY runner / artifact collector。
+- root `Cargo.toml` / package metadata: opt-in package registration と release contamination check。
+
+Critical risks / reviewer focus:
+- Harness code が production binary に混ざっていないこと。
+- Observability hook が read-only で、input/action path を bypass していないこと。
+- Test が fixed sleep 依存ではなく structured feedback / timeouts / artifacts を持つこと。
+- Panel mouse / quit latency regression が今後「unit test だけで done」にならない程度の user-visible path を cover すること。

+
+## 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.

+<!-- event: implementation_report author: hare at: 2026-06-13T14:38:03Z -->
+
+## 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.

+
+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.

+- 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.
+
+Validation:
+- `cargo fmt --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 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).
+- `cargo check -p yoi-e2e --all-targets --features e2e` — passed.
+- `git diff --check` — passed.
+
+Remaining gaps / risks unchanged:
+- The E2E harness remains Unix PTY based.
+- The screen artifact remains raw PTY output rather than a parsed terminal snapshot.

+
+## 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.

+- Added feature-gated read-only TUI observer behind `tui/e2e-test` / `yoi/e2e-test`; normal builds do not compile observer module, event payload construction, row DTOs, or background hold seam.
+- Added Panel mouse selection E2E that waits for rendered rows, verifies terminal mouse capture output (`?1000h` and `?1006h`), sends click through PTY, asserts selection change, and asserts no action dispatch.
+- Added Panel quit latency E2E that creates a feature-gated pending reload barrier, sends Ctrl+C through PTY, and asserts bounded exit.

+
+## 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。
+
+---
+
+<!-- event: decision author: orchestrator at: 2026-06-13T15:45:26Z -->
+
+## 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.
-- 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.
+Plugin design must not let external packages bypass Worker history, prompt/context invariants, scoped tool permissions, restore snapshot authority, or launch-policy authority.
 
-## 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.
-- `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.
-- 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.
+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.
+
+## Plugin runtime
+
+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:
-  - Tools callable by the LLM through the normal ToolRegistry / permission / scope path;
-  - Hooks observing or influencing Pod/Worker lifecycle through the existing Hook boundary, not by directly mutating worker history/context.
-- Separate plugin description/registration from plugin runtime implementation.
-  - A plugin manifest should declare provided tools/hooks, required capabilities, configuration schema or config values, and trust/runtime type.
-  - Runtime implementations can include MCP, declarative config hooks, and WASM in separate phases.
-- Keep MCP as a related backend, not the whole plugin model.
-  - MCP servers remain untrusted external capability providers bridged through allowlists, bounded output, scope/permission policy, and explicit resource/prompt use.
-- Define a declarative hook path for simple TOML/config-only behavior where code execution is unnecessary.
-- Define a WASM plugin direction for programmable Hooks/Tools.
-  - WASM modules must receive explicit host imports/capabilities only.
-  - File/network/process access must not be ambient; all external effects go through host-provided capability APIs and existing policy checks.
-  - Tool outputs must be bounded and recorded through normal history/tool-result paths.
-- Preserve LLM context/history invariants.
-  - Plugins must not inject cross-turn invisible context.
-  - If plugin output becomes model-visible, it must enter through durable history/tool/hook paths according to existing rules.
-- Preserve scope and permission invariants.
-  - Plugin-provided tools must not bypass `ScopedFs`, manifest tool permission policy, child scope delegation, or web/network policy.
-- Clarify trust model and lifecycle.
-  - Builtin vs project vs user plugins.
-  - Discovery/enablement through manifest/profile/config.
-  - Versioning / compatibility boundaries.
-  - Diagnostics when a plugin cannot load or asks for unavailable capabilities.
-
-## Non-goals
-
-- 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.
+- Define Plugin as a user-facing layer over `pod::feature`, not as the feature API itself.
+  - Plugin package/config/runtime code eventually contributes through `pod::feature`.
+  - `pod::feature` remains responsible for contribution declarations, lifecycle, diagnostics, and registration plumbing.
+  - Plugin remains responsible for package enablement, provenance, runtime selection, host API grants, and Plugin-layer permission/trust policy.
+- Use the terms `Plugin runtime`, `Plugin surface`, and `Plugin host API`; avoid durable/user-facing use of `contribution category`.
+- Plugin surfaces are Tool / Hook / Service / Ingress.
+- Service has a Pod-lifetime lifecycle contract; it does not imply WebSocket/SSE/raw network support.
+- Ingress is `host.ingress.submit(typed external event)`; host routing decides notify/run/drop/diagnostic.
+- External outbound side effects are Tool surface entries with external-write metadata, not a separate Outbound surface.
+- Initial general-purpose Plugin host APIs are only `https` and `fs`.
+- `ingress.submit` and `diagnostics` are surface-intrinsic host calls, not broad ambient capabilities.
+- Do not expose a generic `web` API in the initial Plugin model.
+- Define Plugin-layer permission and trust model separately from `pod::feature`.
+  - Do not rely on feature-level `HostAuthority` / authority grants for Plugin permissions.
+  - Plugin grants are tied to package identity/runtime/user or workspace config, not feature install reports.
+  - Plugin policy decides which surfaces and host APIs a Plugin runtime can use.
+- Define runtime families separately.
+  - Declarative/config-only Plugins
+  - WASM Plugins
+  - External process Plugins only as an explicit future/optional runtime
+  - MCP remains a separate feature-backed protocol integration, not the Plugin permission model.
+- Plugin metadata, config, external data, and package content are untrusted input.
+- Plugin enablement must be explicit.
+  - package presence/discovery alone cannot enable or execute Plugin code
+  - 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.
 
 ## Acceptance criteria
 
-- The repository has a documented plugin architecture proposal covering Tools, Hooks, runtimes, capability model, trust model, and discovery/enablement.
-- MCP is positioned as one plugin backend / bridge and linked to `mcp-integration`, not treated as the only extension mechanism.
-- The proposal explicitly explains why arbitrary scripting languages are deferred and why WASM is the initial programmable runtime direction.
-- The design preserves existing scope, permission, history, and prompt-context invariants.
-- Follow-up implementation tickets can be cut independently for declarative hooks, WASM runtime, and MCP bridge integration.
-- Any code changes in this ticket, if taken beyond design docs, are limited to safe internal boundaries and have focused tests.

+- 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`
-- `./.insomnia/plugins/<id>.insomnia-plugin`
+- `${XDG_DATA_HOME:-~/.local/share}/yoi/plugins/<id>.yoi-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`.
+The package should be easy to copy, inspect, cache, and pin while preserving Yoi's scope, permission, history, prompt-context, and trust invariants. Workspace plugins may come from a repository checkout and must not execute merely because an archive exists under `./.yoi/plugins`.

   - Specify archive safety rules, including path traversal rejection, bounded extraction, and deterministic digest calculation.
 - Define plugin stores and source/trust mapping.
-  - User plugin store: `~/.config/insomnia/plugins/`.
-  - Workspace/project plugin store: `./.insomnia/plugins/`.
-  - Map stores to the existing source vocabulary (`User`, `Project`/workspace, and future `Builtin`).

+  - Builtin plugin source: Yoi-distributed `builtin:` registry.
+  - Map stores to the source vocabulary (`user`, `project`, `builtin`).
+  - Treat `user:<id>` and `project:<id>` as distinct plugin references; ambiguous unqualified IDs fail closed.
 - Separate discovery from enablement.
-  - Insomnia may discover plugin packages in configured stores.
-  - Discovered packages must not register Tools/Hooks, initialize WASM, or start MCP servers until explicitly enabled by manifest/profile configuration.
-  - Enablement must resolve package identity, version/API compatibility, source, digest, requested capabilities, and host-granted capabilities.
+  - Yoi may discover plugin packages in configured stores.
+  - Discovered packages must not register Tools/Hooks, initialize WASM, start services, or start MCP servers until explicitly enabled by manifest/profile configuration.
+  - Enablement must resolve package identity, version/API compatibility, source, digest, requested Plugin permissions, and effective Plugin-layer grants.
 - Define package manifest semantics.
-  - Include fields for plugin id, version, plugin API version, runtime kind, source/provenance, metadata, contributed tools/hooks, configuration schema, and requested capabilities.
-  - Capability declarations are requests, not grants; effective grants remain controlled by manifest/profile policy, scope, permissions, web/network policy, secret references, and runtime-specific allowlists.
+  - Include fields for plugin id, version, plugin API version, runtime kind, source/provenance, metadata, contributed tool/hook descriptors, configuration schema, and requested Plugin permissions.
+  - Permission declarations are requests, not grants.
+  - Effective grants are controlled by Plugin-layer policy and existing Yoi manifest/profile policy, scope, tool permissions, web/network policy, secret references, and runtime-specific allowlists.
+  - Do not use `pod::feature` `HostAuthority` / authority grants as the Plugin package permission model.
 - Define runtime-specific packaging expectations.
   - Declarative hooks can be packaged as config-only assets without arbitrary code execution.
-  - WASM plugins should package a module plus schemas/assets and run only with explicit host imports/capabilities.
-  - MCP should remain modeled as a backend/bridge; packaging an MCP server or process command requires explicit process/capability design and must not auto-start from workspace packages.
+  - WASM plugins should package a module plus schemas/assets and run only with explicit host imports/capabilities decided by Plugin-layer policy.
+  - MCP is separate from Plugin packaging for now; packaging or launching an MCP server from a plugin package is out of scope unless a later Ticket defines that bridge explicitly.
 - Define cache/pinning behavior.
   - Extract or materialize packages into a digest-keyed cache before runtime initialization.
   - Consider digest pins in manifest/profile enablement entries or a future lock file.

+- Follow-up implementation tickets can be cut independently for manifest/profile enablement, package discovery, archive validation/cache, Plugin permission policy, WASM packaging, and any future MCP/plugin bridge alignment.
 - Any code changes in this ticket, if taken beyond design docs, are limited to safe internal boundaries and focused tests.

+## 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。

+## Decision
+
+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。
+
+状態:
+- 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。
+
+---
+
+<!-- event: comment author: intake at: 2026-06-14T15:12:07Z -->
+
+## 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。
+

+
+<!-- event: decision author: yoi-orchestrator at: 2026-06-14T15:49:34Z -->
+
+## 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。

+## Implementation report
+
+Implementation report from Coder Pod `yoi-coder-00001KT0Z4BK8`:
+
+Commit:
+- `3c674a70 docs: propose plugin package distribution`
+
+Changed files:
+- `docs/design/plugin-packages.md`
+  - Added the `.yoi-plugin` package/discovery/enablement design proposal.
+- `docs/README.md`
+  - Added the new design doc to the maintained documentation reading order.
+
+Design choices covered:
+- `.yoi-plugin` as a constrained single-file archive with required root `plugin.toml`.
+- Suggested package layout for `module.wasm`, declarative hooks, schemas, README/license, and assets.
+- User/workspace/builtin plugin stores and source-qualified identity: `user:<id>`, `project:<id>`, `builtin:<id>`.
+- Explicit discovery-vs-enablement separation.
+- Store presence under `${XDG_DATA_HOME:-~/.local/share}/yoi/plugins/` or `<workspace>/.yoi/plugins/` is discovery only, never registration/execution.
+- Plugin permission declarations are requests, not grants.
+- Plugin permission policy is explicitly separate from `pod::feature` HostAuthority/grant concepts.
+- Archive validation, traversal rejection, bounded extraction, deterministic digest, digest-keyed cache materialization, and optional pin/lock behavior.
+- Restore uses resolved enabled-plugin plan/digest metadata; fresh discovery must not silently upgrade a restored Pod.
+- Diagnostics guidance without secret leakage.
+- Runtime notes for declarative hooks and WASM.
+- 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.

+- Archive safety covers traversal rejection, unsafe file types, bounded extraction, deterministic digest, digest-keyed cache, and manifest path validation.
+- Diagnostics guidance covers attribution, bounded output, and no secret leakage.
+- Runtime notes cover declarative hooks, WASM initialization from digest cache, host limits, and ToolRegistry/permission checks.
+- MCP is explicitly separate and out of the initial Plugin package runtime.
+- Follow-up implementation cuts are clear and separable.
+- `docs/README.md` cross-reference is appropriate and remains Why/design-oriented.

+Validation performed:
+- Passed: `git diff --check d73f748e..HEAD`
+- Passed: `git diff --check HEAD~1 HEAD`
+- README-listed relative doc target existence checked with shell commands.
+- Manual Markdown/design boundary review completed.
+
+Validation not run:
+- 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.
+
+Conclusion:
+- Approved. No blocking concern remains.

+## 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.

+Review result: approve

+- 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。
-- local subprocess を起動する authority を明示的に表現する。
-  - 既存の filesystem/network/service authority に押し込まない。
-  - command / args / cwd / env / secret refs は explicit config/grant に基づく。
-- Pod lifetime に紐づく feature-provided service / connection manager の lifecycle を表現できるようにする。
-- 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。
-- dynamic contribution は通常の ToolRegistry / PreToolCall permission / history / bounded tool-result path を迂回しない。
-- 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。
-  - title
-  - output schema
-  - annotations
-  - icons or display metadata
-  - execution/task-support metadata
-- rich / structured tool result を bounded serialization できる共通 path を用意する。
-- capability metadata / schemas / descriptions / results は untrusted data として扱う。
-- live list-changed / registry refresh が current run の tool schema consistency を壊さない方針を決める。
-- 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。
+- Treat `pod::feature` as the API layer for contribution registration and lifecycle integration.
+  - Feature code exposes contribution types and installation/runtime hooks.
+  - Feature code does not decide Plugin trust, MCP enablement, or external-provider permissions.
+  - Do not add or rely on `HostAuthority` / authority grants for MCP, Plugin, or provider-process permissions.
+- Add a feature-owned provider/service lifecycle surface sufficient for protocol-backed providers.
+  - startup / ready / failed / stopped diagnostics
+  - Pod lifetime integration and deterministic shutdown hooks
+  - provider failure state that makes dependent dynamic tools unavailable with a clear diagnostic
+- Add dynamic contribution registration for startup-discovered tools.
+  - discovery happens before the tool schema is exposed to a model request
+  - registered tools use stable namespacing and normal ToolRegistry registration
+  - tool schema changes during an active run do not silently mutate the model-visible schema
+- Define bounded refresh semantics for provider list changes.
+  - initial implementation may defer live refresh to a turn boundary or report restart/reinitialize-required diagnostics
+  - silent stale or mid-run schema mutation is not allowed
+- Define provider metadata / schema / result normalization as untrusted data.
+  - 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
+  - MCP may define its own enablement and trust policy on top of this feature API
+- Keep Plugin user-facing format and Plugin permission model outside this Ticket.
+  - 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。
-- 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。
-- feature-owned long-running service lifecycle を Pod lifetime 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。
-- external metadata / schema / result content が untrusted data として扱われる設計になっている。
-- `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。
-- 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。
-- focused tests で authority grant、dynamic registration、permission denial、bounded result、service diagnostics を確認できる。
-- Validation: relevant crate tests、`cargo fmt --check`、`cargo check --workspace --all-targets`、`nix build .#yoi`。
+- `pod::feature` can represent a provider/service that becomes ready, fails, and stops with install/runtime diagnostics visible to the host.
+- A mock protocol-backed provider can register at least one startup-discovered dynamic tool before the first model request that would expose its schema.
+- The dynamic tool is registered as an ordinary Yoi tool and is visible through the same model-visible schema path as built-in tools.
+- A PreToolCall permission denial for the dynamic tool prevents the mock provider from receiving a call.
+- Provider failure makes dependent dynamic tools unavailable with a bounded, comprehensible diagnostic rather than panic or stale silent failure.
+- Oversized or structured provider result data is bounded before being committed as a tool result.
+- 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.
+- Tests/docs make clear that `pod::feature` is not the Plugin permission layer and not the MCP server trust/sandbox layer.
+- 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。
-- external provider 由来の schema / description / annotation / content は instruction ではなく untrusted data として扱う。
-- 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。
-- 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。
-- MCP specific shortcut ではなく、`pod::feature` の長期的な extension surface として成立させる。
+- `pod::feature` is an API/contribution substrate, not a security or trust-policy layer.
+- Plugin is a user-facing package/config/runtime layer that uses `pod::feature`; Plugin permissions are Plugin-layer policy.
+- MCP is a separate feature-backed integration layer; MCP enablement, local server trust, and MCP-specific permissions are MCP-layer policy.
+- Dynamic provider contributions must enter through ordinary Worker / ToolRegistry / permission / history / bounded-result paths.
+- 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。
-- 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。
-- 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。
+- MCP protocol implementation and local stdio transport details.
+- Plugin package format, distribution, provenance, and Plugin runtime permission grants.
+- 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。
-- process execution authority と profile/config authority の責務境界が曖昧になる場合。
-- rich content を model-provider native content block に渡す必要が出た場合。
-- hook / feature / plugin contribution boundary の既存設計と矛盾する場合。
+- The feature API appears to need policy decisions about Plugin trust or MCP server permissions.
+- Dynamic registry refresh would require mutating model-visible tool schema during an active run.
+- Provider result normalization would require provider-native multimodal blocks to bypass normal bounded tool-result serialization.
+- 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。

+- 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.

+
+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.

+## 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.

+
+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。

-## 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:
+- Ticket is queued and explicitly decides to deprecate/remove `yoi.profile.extend` in favor of `yoi.profile.import` plus explicit Lua assignment.
+- Relation checks show no blocker; related launch-policy Ticket `00001KV11DHGZ` is not a dependency for this implementation.
+- 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.

+  - 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.

+## Comment
+
+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`.

+
+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。

+## 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.

+- `TicketRelationQuery` / `TicketOrchestrationPlanQuery` に blocker はない。

+- `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。

+- 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:

+## 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.

+
+<!-- event: review author: hare at: 2026-06-13T18:58:42Z status: approve -->
+
+## 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.

+## 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。

+
+## Decision
+
+Routing decision: implementation_ready
+
+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。
+- Orchestrator worktree is clean。
+
+IntentPacket:
+
+Intent:
+- `cargo test -p yoi-e2e --features e2e ...` を任意タイミングで実行しても、harness が最新 source から E2E 用 `yoi` binary を build して直接 PTY spawn するようにする。
+
+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`.

+  - 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, and binary path.
+  - Expanded command-failure diagnostics to include command args.
+- `tests/e2e/tests/panel.rs`
+  - Updated panel tests to use the fallible cached binary provider.
+
+Validation:
+- `cargo fmt --check` — passed.
+- `git diff --check` — passed.

+  - 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 branch: `ticket-00001KV0TJVN5-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。

+
+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`

+## Intake summary
+
+ユーザー依頼に基づき、Panel Orchestrator の自動作成 orchestration branch 名を `.yoi/ticket.config.toml` の typed config として設定可能にする concrete Ticket を作成した。設定なしでは既存 default `orchestration/<workspace-orchestrator-pod-name>` を維持し、invalid / mismatched worktree は破壊的修復せず diagnostic で止める方針。blocking open question はない。

+
+## Decision
+
+Routing decision: implementation_ready
+
+Reason:
+- Ticket は `queued` で、`.yoi/ticket.config.toml` に Panel Orchestrator の orchestration branch 名を typed config として追加する intent / requirements / acceptance criteria / invariants が具体化されている。
+- `TicketRelationQuery` / `TicketOrchestrationPlanQuery` に blocker はない。
+- Risk は config-schema / git-worktree / panel-orchestration だが、既存 default 維持、invalid branch の Git 操作前拒否、mismatched worktree の非破壊 diagnostic という安全境界が明記済み。
+- 他 queued/inprogress との主な変更面は Panel orchestration worktree/config resolution で、E2E critical path・feature API cleanup・planning return action とは branch/worktree を分けて進められる。merge conflict が出た場合はその時点で止めて報告する。
+
+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:
+- `.yoi/ticket.config.toml` の typed config から Panel Orchestrator の resolved orchestration branch を取得し、worktree create / reuse / restore validation / diagnostics が同じ resolved value を使うようにする。
+
+Binding decisions / invariants:
+- 設定なしの default `orchestration/<workspace-orchestrator-pod-name>` は維持する。
+- invalid branch は Git 操作前に拒否する。
+- dirty/unknown/mismatched worktree を自動修復・削除・checkout しない。
+- Ticket backend / Profile / prompt context への hidden injection ではなく明示 workspace config として扱う。
+
+Validation:
+- Focused ticket config / TUI orchestration 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 ticket_queue_action --lib` — passed (5 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.

+## Implementation report
+
+Integration outcome: merged and validated.
+
+- Implementation branch: `ticket-00001KV0X254D-orchestration-branch-config`
+- Implementation commits: `1c54689e tui: configure orchestration branch`, `fc075bc6 ticket: report orchestration branch config`
+- Review commit: `9ad87dda ticket: approve orchestration branch config`
+- Orchestrator merge commit: `290c4230 merge: orchestration branch config`
+
+Reviewer result:
+- `approve`。typed `[orchestration] branch` config、default preservation、invalid branch pre-Git rejection、create/reuse/restore/queue paths sharing resolved branch、non-destructive mismatch diagnostics を確認済み。
+
+Orchestrator validation after merge:
+- `cargo test -p ticket config --lib`: PASS
+- `cargo test -p tui orchestration_worktree --lib`: PASS
+- `cargo test -p tui configured_orchestration_branch --lib`: PASS
+- `cargo test -p tui ticket_queue_action --lib`: PASS
+- `cargo fmt --check`: PASS
+- `git diff --check`: PASS
+- `cargo build -p yoi`: PASS
+- `target/debug/yoi ticket doctor`: PASS
+
+Residual notes:
+- Broad `cargo test -p tui orchestration --lib` contains a known unrelated stale assertion (`orchestrator_launch_context_uses_orchestration_root_for_runtime_workspace`) from child validation; focused branch/config tests pass.
+
+Next:
+- Mark Ticket done and clean up child coder/reviewer Pods plus implementation worktree/branch.

+## State changed
+
+Implementation branch was reviewed, approved, merged into the Orchestrator branch as `290c4230`, and validated in the Orchestrator worktree. Focused ticket config / TUI orchestration worktree / configured branch / queue action tests, formatting, diff check, `cargo build -p yoi`, and `yoi ticket doctor` passed. Ticket implementation work is done; closure remains separate.
