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

+## 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.

+## 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:

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

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

+  - 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.

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

+Recovery action: hand off dirty worktree to a replacement Coder.
+
+User requested continuing with a different Coder after the prior Coder Pod stopped unexpectedly.

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

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