## Intake summary

Panel から Quit するときに断続的な遅延が発生する問題について、調査・修正用 Ticket を作成した。現象は明確だが再現条件や遅延箇所は未特定のため readiness は `spike_needed`。Orchestrator はまず `crates/tui/src/multi_pod.rs` の Panel event loop / `PendingReload` / Quit handling / queue-attention notice dispatch / snapshot reload 周辺を調査し、Quit が非本質的な background work の完了待ちでブロックされない修正へ routing できる。関連 closed Ticket `00001KTFMMZP0` は Panel 非同期遷移改善で、今回の Quit 遅延とは別の follow-up として扱う。

<!-- event: decision author: orchestrator at: 2026-06-13T10:57:14Z -->

## Decision

Routing decision: spike_needed / queued_waiting_capacity

Reason:
- Ticket は `queued` で要件は明確だが、readiness は `spike_needed`。遅延原因・再現条件・影響 async path は未特定で、まず `crates/tui/src/multi_pod.rs` の Panel event loop / `PendingReload` / Quit handling / queue-attention notice dispatch / snapshot reload 周辺の code-path analysis が必要。
- `TicketRelationQuery` と `TicketOrchestrationPlanQuery` で durable blocker はなかったが、この queue review では `00001KV072V89`（Workspace panel mouse selection）を先に inprogress 受理した。
- `00001KV0723PC` と `00001KV072V89` はどちらも Panel / `multi_pod.rs` の event/input/render/reload surface に触れる可能性が高く、同時 child worktree で進めると conflict risk と reviewer bottleneck が大きい。
- `00001KV04NJ8D` は single-Pod rewind / Pod protocol 周辺の別 surface として parallel start 可能なため、現在の capacity は `00001KV072V89` と `00001KV04NJ8D` に割り当てる。

Evidence checked:
- Ticket body / thread / artifacts（artifacts なし）。
- relation records: なし。
- orchestration plan records: この routing pass で `00001KV072V89` との `conflicts_with` と waiting-capacity note を記録。
- related closed Ticket `00001KTFMMZP0`: Panel non-blocking transition work は closed で、`PendingReload` / background refresh / attach-return path の背景として関連するが、今回の Quit 遅延とは別 follow-up。
- code map: `crates/tui/src/multi_pod.rs` の run loop、`PendingReload`、Quit action、queue-attention notice dispatch、terminal event poll/reload interaction。
- workspace/Pod state: Orchestrator worktree clean。implementation Pods はまだ起動していないが、この routing pass で 2 件を受理予定。

Next action:
- この Ticket は queued のまま保持する。
- `00001KV072V89` の branch が統合されるか、panel surface conflict が低いと再評価できた時点で、改めて `queued -> inprogress` 受理を検討する。
- 受理時の first step は read-only/code-path spike とし、Quit が pending background work / notice dispatch / snapshot reload で block される path を特定してから修正する。

Escalate if:
- Quit 遅延の修正が terminal cleanup、Pod lifecycle authority、Ticket workflow semantics、または broad TUI runtime-loop redesign を必要とする場合。
- 原因が Panel 外（OS terminal / shell / external command / specific provider/network）にある証拠が出た場合。

## Decision

Queue attention reviewed: no duplicate start.

Actual state check:
- `00001KV072V89` is `inprogress` with live spawned child `coder-00001KV072V89-panel-mouse` and worktree `/home/hare/Projects/yoi/.worktree/panel-mouse-selection`.
- `00001KV04NJ8D` is `inprogress` with live spawned child `coder-00001KV04NJ8D-rewind` and worktree `/home/hare/Projects/yoi/.worktree/rewind-live-refresh`.
- This Ticket remains `queued`.
- `TicketRelationQuery` still shows no durable dependency blockers, but the existing OrchestrationPlan `conflicts_with` / `waiting_capacity_note` remains applicable: this Ticket likely touches the same Panel `multi_pod.rs` event-loop surface as `00001KV072V89` and should wait until that branch is integrated or conflict surface is re-evaluated.

Decision:
- Do not start another Coder Pod for this Ticket now.
- Keep queued; re-evaluate after `00001KV072V89` completion/integration or explicit human override.

## Decision

Routing decision: implementation_ready

Reason:
- Ticket は `queued` で、Quit 遅延の原因特定と修正の intent / requirements / acceptance criteria / binding invariants / implementation latitude / escalation conditions が揃っている。
- `readiness: spike_needed` だが、調査対象は `crates/tui/src/multi_pod.rs` の Panel event loop / `PendingReload` / Quit handling / queue-attention notice dispatch / snapshot reload 周辺に bounded されており、専用 worktree の Coder に first-step code-path spike と修正を委ねられる。
- `TicketRelationQuery` に durable dependency blocker はない。
- 以前の OrchestrationPlan `conflicts_with` / `waiting_capacity_note` は `00001KV072V89`（Panel mouse selection）との同時編集 conflict を理由に queued 待機としていたが、同 Ticket は review/merge/validation/cleanup 済みで `done`。現在の Orchestrator worktree は clean で、related implementation Pods/worktrees も cleanup 済み。
- risk flags は `tui-panel` / `shutdown-latency` / `async-cancellation` だが、Ticket は Quit の authority/invariants と escalation conditions を明記しており、実装前に追加の human decision は不要。

Evidence checked:
- Ticket body / thread / artifacts。
- relation records: なし。
- orchestration plan records: 既存 `conflicts_with` / `waiting_capacity_note` を確認し、blocking condition（`00001KV072V89` の未統合）は解消済み。
- related Ticket `00001KTFMMZP0`: Panel non-blocking transition work は closed で、`PendingReload` / background refresh / attach-return path の背景として参照する。
- current code/workspace state: `00001KV072V89` と `00001KV04NJ8D` は merge/validation/cleanup 済み。Orchestrator worktree clean。visible spawned implementation Pods なし。

IntentPacket:

Intent:
- `yoi panel` / workspace Panel の Quit 操作で、ユーザー入力後に Panel の background reload / notice dispatch / snapshot load / Pod observation など非本質的処理待ちによる断続的な遅延が起きないよう、原因を特定して修正する。

Binding decisions / invariants:
- Quit はユーザーの明示的な終了意思であり、Panel の観測/reload/通知送信完了待ちで遅延してはならない。
- 端末状態復旧、描画 backend の正常終了、Rust drop による安全な abort など、最小限の終了処理は維持する。
- Ticket lifecycle authority、Pod authority boundary、Panel row/action semantics、Companion/Orchestrator composer target semantics は変更しない。
- `resources/prompts` や durable Ticket schema 変更は想定しない。必要になった場合は escalation。

Requirements / acceptance criteria:
- `Ctrl+C` / `Ctrl+D` など現行 Quit 経路が pending background work によって目に見えて遅延しない。
- 遅延原因と修正方針を implementation report に説明する。
- 可能な範囲で unit test / regression test を追加し、Quit 経路が pending background work にブロックされないことを検証する。
- 自動化が難しい場合は manual validation 手順と観測結果を report する。

Implementation latitude:
- まず `crates/tui/src/multi_pod.rs` の event loop / `PendingReload` / Quit handling / terminal event polling / queue-attention notice dispatch / snapshot load を code-path spike する。
- 修正手段は、不要 await の回避、cancellable background work の abort/drop、event-loop priority adjustment、test seam 追加などから Coder が選んでよい。
- 再現が難しい場合は遅延し得る code path を単体再現できる test seam を優先してよい。

Escalate if:
- Panel public UX、Ticket lifecycle semantics、Pod shutdown semantics、authority boundary の変更が必要になる。
- 端末 cleanup や Pod process lifecycle safety を犠牲にしないと遅延を解消できない。
- 原因が Panel 外（OS terminal / shell / external command / provider/network）にある証拠が出た。

Validation:
- focused test for Quit not waiting on pending background work。
- `cargo fmt --check`。
- `git diff --check`。
- 変更範囲に応じて `cargo test -p tui ...` / `cargo check -p tui --all-targets`。
- 可能なら manual `yoi panel` Quit observation を report。

Current code map:
- `crates/tui/src/multi_pod.rs`: Panel run loop、Quit key handling、`PendingReload`、background reload / attention notice / snapshot observation paths。
- `crates/tui/src/workspace_panel.rs`: ViewModel は参照のみ。row/action semantics は変更しない。

Critical risks / reviewer focus:
- Quit を速くするために terminal cleanup / safe abort / Pod lifecycle を壊していないこと。
- nonessential background work が Quit を block しないこと。
- Panel/Ticket/Pod authority semantics と row/action semantics が変わっていないこと。
- Regression test が実際に pending background work block を防ぐ性質を持つこと。

<!-- event: state_changed author: orchestrator at: 2026-06-13T11:27:38Z from: queued to: inprogress reason: orchestrator_acceptance_after_conflict_resolved field: state -->

## State changed

Ticket evidence、relation records、existing OrchestrationPlan waiting/conflict notes、related completed Panel mouse integration、visible Pod/worktree state、and clean Orchestrator workspace were checked. The prior conflict/capacity blocker is resolved; no durable dependency blockers remain. Implementation can proceed in a dedicated child worktree with a first-step code-path spike and focused regression test before changing Quit behavior.

## Implementation report

Implementation report for Ticket 00001KV0723PC

Commit: cfe411e50d7361228e509a18699477b13c4bc3e7 (`fix: avoid panel quit notice wait`)

Observed / identified delay cause:
- In `crates/tui/src/multi_pod.rs`, the workspace Panel run loop handled a completed `PendingReload` before polling terminal input.
- When the reload result requested Orchestrator queue-attention notification, the loop awaited `dispatch_orchestrator_queue_attention_notice(request)` inline.
- That dispatch path can wait on Unix socket connect/read/write operations and their timeouts. While it was awaited inline, queued terminal events such as `Ctrl+C` / `Ctrl+D` could not be observed, so an explicit Quit could be delayed by non-essential notice dispatch work.

Fix summary:
- Added `PendingQueueAttentionNotice`, a cancellable background task wrapper for queue-attention notice dispatch.
- Changed the Panel run loop to start queue-attention notice dispatch asynchronously after reload and only harvest the result when the task is already finished.
- Added explicit quit cleanup through `abort_panel_background_work_for_quit`, aborting both pending reload and pending queue-attention notice work before returning `MultiPodOutcome::Quit`.
- Also abort the background notice before foreground open/action paths that already abort reload work, so non-essential notice dispatch does not contend with user-directed operations.
- Preserved terminal/backend shutdown behavior by keeping the existing return path and relying on explicit abort plus Rust `Drop` cleanup for background tasks.

Files changed:
- `crates/tui/src/multi_pod.rs`

Regression coverage:
- Added `multi_quit_aborts_background_reload_and_notice_without_waiting`, which starts never-completing reload and notice tasks, exercises the quit abort helper under a timeout, and verifies both tasks are cancelled.
- Existing reload overlap behavior remains covered by `multi_poll_reload_does_not_overlap_in_flight_reload`.

Validation commands/results:
- `cargo fmt --check` — passed
- `git diff --check` — passed
- `cargo test -p tui multi_quit_aborts_background_reload_and_notice_without_waiting --lib` — passed
- `cargo test -p tui multi_poll_reload_does_not_overlap_in_flight_reload --lib` — passed
- `cargo check -p tui --all-targets` — passed

Residual risks / manual validation notes:
- No broad runtime-loop rewrite was done. Foreground user-directed operations that are already awaited by the Panel can still occupy the loop; this change targets the identified non-essential background notice dispatch delay path.
- I did not run an interactive manual `yoi panel` session from this Coder environment. Recommended manual check: start `yoi panel`, trigger a reload/queued Ticket condition that would dispatch queue-attention notice, then press `Ctrl+C`/`Ctrl+D` while the notice target is slow or unavailable; the Panel should exit promptly while terminal state is restored.

## Review: approve

Review: approve

Evidence:
- Reviewed Ticket intent/criteria and `git diff 9dacc90e..HEAD` for commits `cfe411e5` and `8de82836`.
- The reported delay cause is plausible in the previous loop shape: a completed reload was processed before input polling and could inline-await queue-attention notice dispatch; that dispatch uses Pod socket connect/read/write paths, so queued `Ctrl+C` / `Ctrl+D` input could wait behind nonessential notice work.
- The implementation changes only `crates/tui/src/multi_pod.rs` plus the implementation report. Queue-attention notice dispatch is now wrapped in a cancellable `PendingQueueAttentionNotice`, started in the background, and harvested only after completion. Reload dispatch is guarded against overlap.
- Quit handling now calls `abort_panel_background_work_for_quit`, aborting pending reload and pending queue-attention notice tasks before returning the existing `MultiPodOutcome::Quit`; this keeps the established terminal/backend cleanup return path intact.
- Existing foreground open/action helper paths also abort the nonessential pending notice before returning user-directed outcomes, so stale notice dispatch does not block those paths.
- No Ticket lifecycle authority, Pod authority boundary, Panel row/action semantics, composer target semantics, prompt resources, or Ticket schema changes were introduced.
- The regression test starts never-completing reload and notice futures, exercises the quit abort helper under a timeout, and verifies cancellation of both tasks. This is a meaningful regression for the pending-background-work latency path rather than only checking that a helper was wired.

Validation performed:
- `cargo test -p tui multi_quit_aborts_background_reload_and_notice_without_waiting --lib` — passed.
- `cargo test -p tui multi_poll_reload_does_not_overlap_in_flight_reload --lib` — passed.
- `cargo fmt --check` — passed.
- `git diff --check` — passed.
- `cargo check -p tui --all-targets` — passed.

Risks / notes:
- I did not run an interactive `yoi panel` manual latency check. The code-path review and focused tests cover the identified nonessential reload/notice wait path.

- `cargo fmt --check`: PASS
- `git diff --check`: PASS
- `cargo check -p tui --all-targets`: PASS

Residual notes:
- Interactive `yoi panel` manual latency check は未実施。ただし、code-path review と focused tests で特定された nonessential reload/notice wait path は cover されている。
- Ticket lifecycle authority、Pod authority boundary、Panel row/action semantics、composer target semantics、prompt resources、Ticket schema は変更していない。

Next:
- Ticket を `done` に遷移し、panel quit child Pods / worktree / branch を cleanup する。close は別途明示権限がある場合に行う。

## Comment

Post-merge measurement report: Panel quit latency is still present / not proven fixed.

User report:
- 「相変わらずPanelをquitする際の遅延も解決してない」

Measurement performed after merge in Orchestrator worktree `/home/hare/Projects/yoi/.worktree/orchestration/yoi-orchestrator`:
- Built current debug binary: `cargo build -p yoi`。
- PTY measurement command shape: pipe `sleep <delay>; Ctrl+C` into `script -q -c 'target/debug/yoi panel --workspace ...'` and measure process elapsed.
- Current debug binary `target/debug/yoi` results with Ctrl+C sent after 1.5s:
  - approx after Ctrl+C: 2488ms, 2561ms, 2453ms, 2558ms, 2507ms。
- Varying Ctrl+C send delay against current debug binary:
  - delay 0.2s -> total 3958ms
  - delay 1.0s -> total 3919ms
  - delay 2.0s -> total 4062ms
  - delay 3.5s -> total 4095ms
  - delay 5.0s -> total 6309ms
- Installed `/home/hare/.nix-profile/bin/yoi` showed approx 24-25ms after Ctrl+C in the same scripted shape, and also appeared not to contain the new test/symbol strings, so binary-path freshness differs between measurements.

Conclusion:
- The original merge was based on a plausible code-path fix and focused tests, but no interactive/user-path latency measurement was done before marking done。
- The current debug binary still shows a roughly 4s startup/quit floor in the PTY measurement, so the merged fix did not prove the user's observed latency is gone and may have missed a different blocking path。
- Follow-up must identify the actual user command/binary path and measure `yoi panel` quit latency before and after any further fix. If the relevant path is current source/debug, this Ticket should be treated as not actually resolved.
