<!-- event: decision author: yoi-orchestrator at: 2026-06-27T19:08:35Z -->

## Decision

Routing decision: blocked_by_dependency_or_missing_authority

Reason:
- Dashboard Queue 後に Ticket / relations / orchestration plan / workspace state を確認した。
- 本 Ticket は `00001KW55B33B` (`embedded worker-runtimeをworker crate実行に接続する`) に `depends_on` relation を持つ。
- `00001KW55B33B` は queued で、さらに `00001KW55B32Y` execution backend boundary が inprogress のため blocked。
- Workspace Companion を実 LLM 実行 Worker として起動するには、embedded Runtime が既存 `worker` crate execution に接続済みである必要があるため、依存 chain 完了前に開始しない。

Evidence checked:
- Ticket body: Companion bootstrap、Worker Console behavior、API cleanup、Validation/evidence、Non-goals。
- Relations: outgoing `depends_on -> 00001KW55B33B` and related Web Console/Worker Console Tickets。
- Orchestration plan: blocker record `orch-plan-20260627-190816-1` を追加。
- Workspace state: `00001KW55B32Y` accepted/inprogress; `00001KW55B33B` queued/blocked。

Next action:
- 本 Ticket は queued のまま待機。
- `00001KW55B33B` が done になった後に再 routing する。

## Decision

Routing decision:

Queue continuation was explicitly requested. The upstream dependency `00001KW55B33B` is now closed after review, merge, validation, and cleanup. This Ticket is therefore unblocked and accepted for implementation.

Plan:
- Create child implementation worktree:
  - `/home/hare/Projects/yoi/.worktree/00001KW55B33H-workspace-companion-llm-worker`
- Branch:
  - `work/00001KW55B33H-workspace-companion-llm-worker`
- Route implementation to a sibling Coder Worker with focused write scope.
- Route read-only review to a sibling Reviewer Worker after implementation.
- Orchestrator retains merge, final validation, Ticket completion, child worktree/branch cleanup, and final reporting.

Review/implementation focus:
- Workspace Backend bootstraps `workspace_companion` as an executable Worker with real `worker` crate execution adapter.
- Worker list / Worker Console use the normal `runtime_id + worker_id` authority and Backend Worker input API.
- Console Send reaches real Worker execution path and uses `protocol::Event` / transcript projection, not Companion-specific fake/providerless messages.
- provider/model/secret/profile/authority absence returns typed diagnostic and does not present the Worker as input-capable.
- `/api/companion/messages`, if retained, must not return fake response and should be a thin normal Worker input path wrapper or non-authoritative compatibility path.
- Browser-facing API must not leak raw handles, sockets, session paths, credentials, secret refs, raw manifest paths, or broad authority internals.

Operational note:
- User instructed not to use `StopPod` for now after repeated stop/hang symptoms. Cleanup will skip role-Pod shutdown and remove only child worktree/branch unless this is explicitly reauthorized.

<!-- event: state_changed author: yoi-orchestrator at: 2026-06-28T06:02:54Z from: queued to: inprogress reason: dependency_closed_and_queue_continues field: state -->

## State changed

Queue continuation requested by user. Dependency `00001KW55B33B` is closed with merge and validation complete, so this Ticket has no remaining blockers. Accepting implementation before child worktree / role Pod side effects.

## Implementation report

Implementation kickoff:

- Worktree created: `/home/hare/Projects/yoi/.worktree/00001KW55B33H-workspace-companion-llm-worker`
- Branch: `work/00001KW55B33H-workspace-companion-llm-worker`
- Coder Worker spawned: `yoi-coder-00001KW55B33H-companion-llm`

Scope notes:
- Coder write scope is limited to `crates/workspace-server/**`, `crates/worker/**`, `crates/worker-runtime/**`, `web/workspace/**`, `resources/profiles/**`, `resources/prompts/**`, root `Cargo.toml`, `Cargo.lock`, and `package.nix` if dependency/package changes are needed.
- Coder is instructed not to modify Ticket records and not to operate in root/orchestration worktrees.

Implementation focus:
- bootstrap `workspace_companion` as an executable Worker using embedded Runtime + `worker/runtime-adapter`
- normal Worker list / Worker Console attach path via `runtime_id + worker_id`
- Send through Backend Worker input API to real Worker run lifecycle
- no fake/providerless Companion response
- provider/profile/model/secret/authority absence as typed diagnostic and not input-capable
- `/api/companion/messages`, if retained, must not be a separate fake response path
- preserve Browser-facing non-leak of raw handles, paths, credentials, secret refs, and raw manifest paths

Operational note:
- User instructed not to use `StopPod` for now. Later cleanup will skip role-Pod shutdown and remove only child implementation worktree/branch unless explicitly reauthorized.

## Implementation report

Implementation routing diagnostic:

Initial Coder Worker `yoi-coder-00001KW55B33H-companion-llm` failed before producing implementation output with provider error `context_length_exceeded`. This appears to be a prompt/context-size failure rather than an implementation result.

Operational response:
- Per current user instruction, `StopPod` will not be used.
- A replacement Coder Worker will be spawned with a shorter bootstrap instruction and the same implementation worktree, if scope delegation is accepted.
- The replacement Coder should read the Ticket and current code directly from the worktree rather than receiving the full requirement text in the initial prompt.

## Implementation report

Implementation/verification report:

Replacement Coder completed a verification pass in the child worktree. No code changes were made and no implementation commit was created beyond the branch baseline.

Reported branch/head:
- `0c5a769aa90744cf12299c6d301ebfb3186d763f ticket: accept workspace companion llm worker`

Reported outcome:
- Existing code after upstream `00001KW55B33B` appears to satisfy this Ticket's main implementation goal.
- Workspace Companion is visible as an embedded Runtime normal Worker.
- The `worker` runtime-adapter path is used; providerless/fake responses were not found.
- Input unavailable state is represented through Worker input-capable/diagnostic projection.
- Workspace web Worker Console uses `runtime_id + worker_id` routing.

Reported validation:
- `cargo fmt --check`: success
- `cd web/workspace && deno task test`: success
- `cd web/workspace && deno task check`: success
- `cd web/workspace && deno task build`: success
- `cargo test -p yoi-workspace-server`: success
- `cargo check -p yoi`: success
- `git diff --check`: success
- `nix build .#yoi`: success

Orchestrator note:
- Because no code commit was produced for this Ticket, a reviewer will be asked to explicitly verify whether upstream merged implementation fully satisfies `00001KW55B33H` or whether additional changes are required.

## Implementation report

Review kickoff:

Reviewer Worker spawned to verify the no-code implementation/verification outcome for `00001KW55B33H`.

- Reviewer Worker: `yoi-reviewer-00001KW55B33H-companion`
- Review mode: read-only review of current child worktree code state after upstream `00001KW55B33B` merge
- Special focus: confirm whether no additional code changes are required for this Ticket, or identify concrete blockers

Review focus:
- `workspace_companion` bootstraps as an executable normal Worker via embedded Runtime + `worker/runtime-adapter`
- Worker list / Worker Console attach path uses `runtime_id + worker_id`
- Send uses Backend Worker input API -> embedded Runtime execution backend -> real Worker run lifecycle
- protocol events / transcript use existing Console rendering path
- missing provider/config/profile/secret/authority is typed diagnostic and not input-capable
- `/api/companion/messages` does not return fake/providerless response
- Browser-facing API does not leak raw handles, socket paths, session paths, credentials, secret refs, raw manifest paths, or broad authority internals
- public `can_stream_events` / `can_read_bounded_transcript` flags are not revived

## Review: request changes

request_changes

静的レビューの結果、upstream の `worker-runtime` adapter 実装は存在するが、Ticket `00001KW55B33H` 自体の受け入れ条件はまだ満たされていない。

## Blockers

1. **`/api/companion/messages` がまだ hard-coded な非実行 path のまま**

   - `server.rs:533-537` は `/api/companion/messages` を直接 `api.companion.send_message(request)` に route している。
   - `companion.rs:161-182` は non-empty input を常に `companion_llm_not_connected` で reject する。
   - これは Backend Worker input API の thin wrapper ではなく、real Worker run lifecycle に到達しないため、Ticket の `/api/companion/messages` 要件を満たさない。

2. **Companion status / transport が古い “not connected” limitation をまだ宣言している**

   - `companion.rs:337-342` が `completion: "not_connected"` を返し、実 Worker/LLM execution 接続まで browser input は disabled と説明している。
   - Ticket の目的は Workspace Companion を real LLM execution に接続して Web Console から使えるようにすることなので矛盾している。

3. **Companion bootstrap が適切な Companion profile / config bundle を解決していない**

   - `companion.rs:257-267` は `profile: Some(ProfileSelector::RuntimeDefault)` / `config_bundle: None` で spawn している。
   - `hosts.rs:2188-2191` では `RuntimeDefault` が `runtime_default` と投影されるだけで、Companion profile として表示されない。
   - Ticket は Companion Profile / config bundle を解決し、`workspace_companion` / 適切な companion Profile として表示することを求めている。

4. **focused tests が古い rejected/no-output behavior をまだ assert している**

   - `companion.rs:384-399` は `send_message("hello")` が `Rejected`、`companion_llm_not_connected`、runtime transcript empty であることを assert している。
   - `server.rs:1166-1185` は `/api/companion/messages` が rejected で transcript empty であることを assert している。
   - Ticket は bootstrap、input dispatch、assistant output、observation event、transcript projection が Worker execution path を通ることを proving する tests を求めている。

5. **raw path leak 懸念**

   - `server.rs:227-235` の `WorkspaceResponse` に `local_root: PathBuf` が含まれる。
   - `server.rs:335-339` が `/api/workspace` に `api.config.workspace_root` を serialize している。
   - “no raw handle/path/credential leaks” を Browser-facing workspace API 全体に適用するなら違反の可能性がある。Worker projection 自体はより注意深く redacted されているが、この public path field は残っているため要確認・必要なら修正が必要。

## 確認済み / non-blocking observations

- upstream embedded runtime adapter は存在する。
  - `WorkspaceApi::new` が `WorkerRuntimeExecutionBackend::from_workspace(...)` を作り、`EmbeddedWorkerRuntime::new_memory_with_execution_backend(...)` に渡している。
- Worker list / Console routing は `runtime_id + worker_id` を使っている。
  - Console Send は `/api/runtimes/{runtime_id}/workers/{worker_id}/input`。
  - Observation WS は `/api/runtimes/{runtime_id}/workers/{worker_id}/events/ws`。
- public `can_stream_events` / `can_read_bounded_transcript` fields は見当たらない。
- `/api/companion/messages` は fake/canned assistant response は返していないが、same execution path / normal Worker input path 要件も満たしていない。

## Validation review

- `.yoi/tickets/00001KW55B33H/item.md` と `thread.md` を読んだ。
- `crates/workspace-server/src/{companion.rs,server.rs,hosts.rs}`、`crates/worker/src/runtime_adapter.rs`、Web Console Svelte/TS paths を静的レビューした。
- test/build は実行していない。
- 現状の `cargo test -p yoi-workspace-server` は古い rejected Companion behavior を assert して通っている可能性があり、この Ticket の acceptance evidence にはならない。

## Implementation report

Change-response implementation report:

Reviewer blockers を修正し、実装 commit を作成済み。Ticket ファイル編集、merge、close、cleanup は未実施。

Commit:
- `ee25cfbcfd90983a24091ef30c0128d653095003 fix: route workspace companion through worker runtime`

変更概要:

- `/api/companion/messages` の旧 `companion_llm_not_connected` 固定拒否経路を廃止し、通常の `RuntimeRegistry::send_input` / Worker runtime 入力経路へ接続。
- Companion status / transport を更新。
  - Worker が input-capable の場合は `completion: "connected"`。
  - missing provider/config/profile/authority 等で input-capable でない場合は `completion: "not_input_capable"` と typed diagnostic。
  - fake/providerless/canned assistant 応答は追加していない。
- Companion bootstrap を `builtin:companion` profile + Companion 用 config bundle sync へ変更。
- `WorkspaceCompanion` intent の embedded profile projection も `builtin:companion` に変更。
- Companion transcript projection を runtime transcript 由来に変更し、旧独自 transcript / 旧非実行 semantics を置換。
- `/api/workspace` の Browser-facing response から raw `local_root: PathBuf` を削除。
- Tests を更新・追加。
  - Companion bootstrap / input dispatch / assistant output / observation event / transcript projection を deterministic test execution backend で検証。
  - legacy `/api/companion/messages` route が Worker runtime 経由で input dispatch することを server test で検証。
  - 旧 `companion_llm_not_connected` 依存 assertion を削除。

Validation:
- `cargo fmt --check`: success
- `cd web/workspace && deno task test`: success
- `cd web/workspace && deno task check`: success
- `cd web/workspace && deno task build`: success
- `cargo test -p yoi-workspace-server`: success
- `cargo check -p yoi`: success
- `git diff --check`: success
- `nix build .#yoi`: success

Residual risks / review focus:
- `/api/companion/*` は互換 route として残しつつ、内部動作は Worker runtime 経路へ寄せている。主 UI path は引き続き `runtime_id + worker_id` の Worker Console。
- provider/profile/secret/authority 欠落時は input 不可 diagnostic になる。実 provider 設定がない環境では Companion は起動 projection されても入力不可。
- deterministic test backend による検証のため、外部 secret/provider には依存しない。
