<!-- event: decision author: yoi-orchestrator at: 2026-06-25T05:46:02Z -->

## Decision

Routing decision: implementation_ready

Reason:
- ユーザーから「続けて」と明示 follow-up があり、queued dependency chain の次 Ticket として再確認した。
- `00001KVXK0WDX` は Service output command model の concrete slice で、WebSocket transport、HTTP request dispatch completion、Domain operation command completion、WIT/PDK/templates update は non-goal として後続に分離されている。
- outgoing `depends_on` は `00001KVXK0WDQ` だが、`00001KVXK0WDQ` は done / merged / reviewed / validated 済み。`TicketShow` derived blockers は空で、implementation acceptance blocker は残っていない。
- incoming dependent `00001KVXK0WE4` は WebSocket driver slice で、この Ticket 完了後に進めるべき後続であり、この Ticket の acceptance blocker ではない。
- bounded context check で current Plugin service lifecycle / ingress queue implementation が `crates/pod/src/feature/plugin.rs` に入り、event dispatch/status diagnostics の拡張点が存在することを確認した。Ticket の残る不確実性は command envelope / validation / grant-check / diagnostics の local implementation に閉じる。

Evidence checked:
- Ticket body / thread: `item.md`, `thread.md`。未解決 planning question は記録されていない。
- Relations / orchestration plan: outgoing depends_on `00001KVXK0WDQ` は done。routing 前 plan は historical blocked_by `00001KVXK0WDQ` のみで、prerequisite 完了により解消済み。accepted plan `orch-plan-20260625-054531-2` を記録済み。
- Related Tickets: `00001KVXK0WD3`, `00001KVXK0WDH`, `00001KVXK0WDQ` は done。
- Code context: `crates/pod/src/feature/plugin.rs` の Plugin Service lifecycle / bounded ingress queue / `PluginIngressEvent` / status diagnostics / component runtime。
- Workspace state: `/home/hare/Projects/yoi/.worktree/orchestration` は clean。inprogress Ticket は 0 件。

IntentPacket:

Intent:
- Service Plugin ingress handler の戻り値として output command envelope を表現し、Host が command ごとに manifest declaration / enablement grant / runtime policy を fail-closed に検査し、結果を service diagnostics/status から追えるようにする。

Binding decisions / invariants:
- Service output command は Tool Plugin の ordinary `ToolOutput` path と型・処理経路・docs/tests で区別する。
- v0 command kind は最小集合に留める: diagnostic/status update, host request dispatch placeholder, websocket send placeholder。
- WebSocket send の実 transport 実装、HTTP request dispatch completion、Domain operation command completion は non-goal。
- Unsupported / ungranted / malformed command は実行せず typed diagnostic にする。
- Unrestricted shell / filesystem command や hidden LLM context injection は絶対に導入しない。
- Existing Plugin Service lifecycle / bounded ingress queue and Component Model-only runtime from prerequisites must not regress.

Requirements / acceptance criteria:
- `handle-ingress` / service event handler result can carry output command list.
- Command has correlation id / source event id / command id / kind / payload / requested_at.
- Host parses, validates, and grant-checks each command.
- Ungranted command is not executed and appears as typed diagnostic.
- Safe diagnostic/status update command is executed or recorded.
- WebSocket send / request dispatch placeholders are grant-checkable and safely unsupported without transport.
- Command execution result is visible from service status / diagnostics or run overview-equivalent state.
- Tests distinguish Tool Plugin output from Service output commands.

Implementation latitude:
- Exact Rust names/enums and JSON/envelope shape may follow existing plugin code style.
- Manifest declaration/grant mapping can be minimal v0 as long as it is explicit and fail-closed.
- Existing tests/fixtures may be extended in `crates/pod/src/feature/plugin.rs`; docs/comments may be updated if needed.

Escalate if:
- Implementing output commands requires actual WebSocket/HTTP transport.
- Current manifest/grant model cannot represent placeholder command grants without broader schema redesign.
- Command results must be persisted in a durable cross-process run overview to satisfy tests.
- Tool Plugin output must be routed through Service command processing.

Validation:
- `cargo test -p pod`
- `cargo check -p yoi`
- `git diff --check`
- `nix build .#yoi --no-link`
- Focused plugin service command tests during development are expected.

Current code map:
- Primary: `crates/pod/src/feature/plugin.rs`。
- Secondary only if necessary: manifest grant declarations/tests/docs comments。
- Avoid: WebSocket transport driver, HTTP request dispatch completion, WIT/PDK/templates service event update, durable cross-process queue, remote runtime protocol。

Critical risks / reviewer focus:
- output commands becoming ambient authority.
- ToolOutput and Service output commands being conflated.
- ungranted/malformed commands partially executing.
- placeholders accidentally performing network I/O。
- scope creep into WebSocket driver or PDK/WIT updates.

Next action:
- `queued -> inprogress` を記録してから worktree-workflow で `/home/hare/Projects/yoi/.worktree/00001KVXK0WDX-plugin-output-commands` を作成し、multi-agent-workflow で Coder/Reviewer sibling loop に進める。

## State changed

Orchestrator acceptance: queued -> inprogress

- 直前確認で `TicketShow` は state `queued`、derived blockers は空。
- outgoing dependency `00001KVXK0WDQ` は done / merged / reviewed / validated 済み。
- accepted plan `orch-plan-20260625-054531-2` を確認した。
- routing decision と IntentPacket は Ticket thread に記録済み。
- これ以降に worktree-workflow で `/home/hare/Projects/yoi/.worktree/00001KVXK0WDX-plugin-output-commands` を作成し、multi-agent-workflow に接続する。

## Implementation report

Implementation orchestration update:

- prerequisite `00001KVXK0WDQ` が done になったため、`00001KVXK0WDX` を再 routing して受理した。
- worktree-workflow に従い、implementation worktree `/home/hare/Projects/yoi/.worktree/00001KVXK0WDX-plugin-output-commands` と branch `work/00001KVXK0WDX-plugin-output-commands` を作成した。
- child worktree では tracked `.yoi` project records を見える状態にし、`.yoi/memory`、local/runtime/log/lock/secret-like `.yoi` paths を sparse-checkout で除外する方針にした。
- Coder Pod `yoi-coder-00001KVXK0WDX-output-commands` を sibling として起動した。write scope は child worktree に限定し、runtime workspace root `/home/hare/Projects/yoi` は startup 要件を満たすため non-recursive read のみにした。
- Coder には root/original workspace と orchestration worktree で read/write/validation/git operation を行わないよう明示した。

## Implementation report

Implementation report:

対象 Ticket:
- `00001KVXK0WDX` — Add Plugin service output command model

変更ファイル:
- `crates/pod/src/feature/plugin.rs`

主な実装:
- Service/Ingress handler の戻り値から `output_commands` を読む Service output command model を追加。
- command envelope に以下を追加。
  - `correlation_id`
  - `source_event_id`
  - `command_id`
  - `kind`
  - `payload`
  - `requested_at`
- v0 command kind を追加。
  - `diagnostic_status_update`
  - `host_request_dispatch`
  - `websocket_send`
- Host 側で envelope parse / field validation / `requested_at` RFC3339 validation / `source_event_id` と ingress event correlation id の照合 / payload size bound / kind-specific payload validation / request・websocket grant check を行うようにした。
- malformed / ungranted / unsupported command は typed diagnostic として記録し、実行しない。
- `diagnostic_status_update` は安全に `component_status` / diagnostics に記録する。
- `host_request_dispatch` / `websocket_send` は grant-check 可能だが、v0 では transport 実行せず `Unsupported` として記録する。
- Service output command results を `PluginIngressDispatchReport` と `PluginInstanceStatus` から見えるように追加。
- ordinary Tool Plugin `ToolOutput` path と Service output command path が混ざらないよう、型・コメント・テストを分離。
- focused tests を追加。
  - diagnostic/status command の記録
  - ungranted request command の reject と status side effect 非実行
  - request/websocket placeholder の grant-check + unsupported 記録
  - malformed envelope の reject

Commit:
- `755d460f0d4e2dccb3f75d9ad980b1e701464a4e feat: add plugin service output commands`

Validation:
- `cargo fmt --check`: success
- `cargo test -p pod service_output_command -- --nocapture`: success (`4 passed`)
- `cargo test -p pod feature::plugin::tests`: success (`77 passed`)
- `cargo check -p yoi`: success
- `git diff --check`: success
- `nix build .#yoi --no-link`: success
- `cargo test -p pod`: failed in known prompt guidance snapshot assertions outside this Ticket (`prompt::catalog::tests::pod_orchestration_guidance_section_renders_resource_body`, `prompt::system::tests::pod_orchestration_guidance_is_included_for_pod_management_tools`), with Plugin tests passing.

Residual risks / notes:
- WebSocket send transport と host request dispatch の実実行は Ticket non-goal に従い未実装で、grant-check 後に `Unsupported` diagnostic として記録する。
- Service output command schema は Rust 側 JSON envelope として追加した。WIT/PDK/templates 更新は non-goal として触っていない。
- Full `cargo test -p pod` の 2 failures は今回の Plugin diff 外の既知 prompt snapshot failure と一致している。

<!-- event: review author: yoi-reviewer-00001KVXK0WDX-output-commands at: 2026-06-25T06:18:37Z status: approve -->

## Review: approve

Review result: approve

確認結果:
- Ticket `00001KVXK0WDX` の IntentPacket / 受け入れ条件に対して、実装 commit `755d460f feat: add plugin service output commands` は妥当。

承認根拠:
- 差分は `crates/pod/src/feature/plugin.rs` のみで、scope creep は見当たらない。
- Service/Ingress handler output の `output_commands` を読む専用経路が追加され、ordinary Tool Plugin `ToolOutput` path とは型・処理・report/status field が分離されている。
- envelope は `correlation_id` / `source_event_id` / `command_id` / `kind` / `payload` / `requested_at` を持ち、unknown fields reject、id / RFC3339 / `source_event_id == ingress correlation_id` / payload size / kind-specific payload を検証している。
- `host_request_dispatch` と `websocket_send` は既存の manifest declaration + enabled grant / allowlist 検査に乗っており、実行段階では `Unsupported` result を返すだけで HTTP/WebSocket transport 実装に踏み込んでいない。
- malformed / ungranted command は `ServiceOutputCommandRejected` diagnostic になり、mixed batch でも安全側に倒して部分的な status update を実行しないテストがある。
- `diagnostic_status_update` は bounded payload/message 経由で `component_status` / diagnostics / `output_command_results` に記録され、外部 side effect や hidden LLM context injection はない。
- Service command results は `PluginIngressDispatchReport` と `PluginInstanceStatus.output_command_results` から追跡可能。
- 追加テストは recorded diagnostic、ungranted rejection、placeholder unsupported、malformed envelope を押さえている。

検証:
- Ticket `item.md` / `thread.md` / orchestration plan / relations を確認。
- child worktree で `git status` / `git log` / `git diff --stat` / diff 内容を read-only 確認。
- read-only 指示のため cargo/nix 等は再実行していない。

Non-blocking note:
- Coder 報告では `cargo test -p pod` が既知の prompt guidance snapshot assertion でのみ失敗、Plugin tests / `cargo check -p yoi` / `git diff --check` / `nix build .#yoi --no-link` は成功。最終統合時に既知 failure 扱いだけ確認すること。

## Implementation report

Integration outcome:

- Coder `yoi-coder-00001KVXK0WDX-output-commands` が implementation branch `work/00001KVXK0WDX-plugin-output-commands` に実装を commit した。
  - implementation commit: `755d460f feat: add plugin service output commands`
- Reviewer `yoi-reviewer-00001KVXK0WDX-output-commands` は read-only review で `approve`。Service output command path と ToolOutput path の分離、fail-closed validation/grant checks、placeholder command の non-transport behavior、diagnostic/status recording、scope creep なしを確認した。
- Orchestrator worktree `/home/hare/Projects/yoi/.worktree/orchestration` で branch `work/00001KVXK0WDX-plugin-output-commands` を merge 済み。
  - merge commit: `d2aa92a7 merge: 00001KVXK0WDX plugin output commands`

Implemented behavior:
- `crates/pod/src/feature/plugin.rs` に Service output command envelope handling を追加。
- `output_commands` は `correlation_id`, `source_event_id`, `command_id`, `kind`, `payload`, `requested_at` を持つ。
- v0 command kinds:
  - `diagnostic_status_update`
  - `host_request_dispatch`
  - `websocket_send`
- Host-side validation:
  - envelope parse / unknown field rejection
  - id and RFC3339 validation
  - `source_event_id` と ingress event correlation id の照合
  - payload size bound
  - kind-specific payload validation
  - manifest declaration + enablement grant / allowlist checks
- malformed / ungranted / unsupported commands は typed diagnostic になり、実行しない。
- `diagnostic_status_update` は bounded payload/message で component status / diagnostics / output command results に記録。
- `host_request_dispatch` / `websocket_send` は grant-check 後に `Unsupported` として記録し、HTTP/WebSocket transport には踏み込まない。
- `PluginIngressDispatchReport` と `PluginInstanceStatus.output_command_results` から command result を追跡可能。

Validation in Orchestrator worktree:
- `cargo fmt --check`: success
- `cargo test -p pod service_output_command -- --nocapture`: success
- `cargo test -p pod feature::plugin::tests`: success
- `cargo check -p yoi`: success
- `git diff --check`: success
- `nix build .#yoi --no-link`: success
- `cargo test -p pod`: failed only in known prompt guidance snapshot assertions outside this Plugin diff:
  - `prompt::catalog::tests::pod_orchestration_guidance_section_renders_resource_body`
  - `prompt::system::tests::pod_orchestration_guidance_is_included_for_pod_management_tools`
  - Plugin-focused tests in the same run passed.

Notes:
- Full `cargo test -p pod` failure is recorded as the same known unrelated prompt-resource assertion issue seen in previous Plugin Tickets, not a blocker for this Ticket.
- Follow-up `00001KVXK0WE4` is dependency-unblocked and can be re-routed next.

Next action:
- Mark Ticket done after this integration/validation evidence.
- Then stop related child Pods and remove only the child implementation worktree/branch.
