+## Decision
+
+Routing decision: implementation_ready
+
+Reason:
+- Dashboard Queue された dependent chain を再確認した。
+- `00001KVZBCQH4` worker-runtime core は done、`00001KVZKST83` FS store feature も done/merged/validated 済み。以前の dependency/capacity blocker は解消した。
+- 本 Ticket は REST command server であり、Non-goals に SSE / WebSocket event stream server が明記されている。WebSocket transport decision は `00001KVZKSTJT` 側で扱い、本 Ticket の implementation latitude には含めない。
+- 現在の inprogress `00001KVZKSV6C` は `crates/workspace-server` foundation、こちらは `crates/worker-runtime` http-server feature が主対象で、conflict risk は bounded。
+
+Evidence checked:
+- Ticket body: `http-server` feature、Runtime process wrapper、REST command endpoints、typed JSON/errors、Browser direct Runtime access exclusion、Non-goals。
+- Relations: outgoing dependency `00001KVZBCQH4` は done。incoming `00001KVZKSTJT`, `00001KVZSGT14` は後続。
+- Orchestration plan: accepted plan `orch-plan-20260625-203533-3` を記録。
+- Workspace state: orchestration worktree clean; current active foundation branch is separate surface.
+
+IntentPacket:
+
+Intent:
+- `worker-runtime` に optional `http-server` feature と最小 Runtime process REST command API を追加する。
+
+Binding decisions / invariants:
+- REST handlers は `Runtime` lib API を呼ぶ wrapper とし、Worker semantics を二重実装しない。
+- Browser は Runtime process に直接接続せず、Backend 経由の前提を docs/comments/API comments に残す。
+- SSE / WebSocket event stream server、Backend HTTP client integration、dynamic Runtime registration、Web Console、full auth model は実装しない。
+- `http-server` disabled 時に core library は HTTP server dependency を強制しない。
+- Runtime authority は Runtime/Worker identity。legacy pod/socket/session path を public REST authority として設計しない。
+
+Requirements / acceptance criteria:
+- `http-server` feature と binary/process wrapper がある。
+- `GET /v1/runtime`, `GET /v1/workers`, `GET /v1/workers/{worker_id}`, `POST /v1/workers`, `POST /v1/workers/{worker_id}/input`, `stop`, `cancel`, `GET transcript` を扱う。
+- typed request/response/error shapes を持つ。
+- runtime id / bind address / store selection を v0 config として扱える。
+- minimal local token placeholder は可。ただし Browser に Runtime credential を渡す前提にしない。
+
+Implementation latitude:
+- HTTP framework/dependency、binary/module split、test helper、typed response shapes の詳細は Coder が選べる。
+- FS store 使用は既存 feature を使う範囲まで。新しい persistence design は不要。
+
+Escalate if:
+- WebSocket/SSE observation 実装が必要になりそうな場合。
+- Backend integration や dynamic runtime registration を同時に実装しないと REST command server が成立しない場合。
+- Core Runtime API の大幅変更が必要になる場合。
+
+Validation:
+- `cargo fmt --all`
+- `cargo test -p worker-runtime --no-default-features`
+- `cargo test -p worker-runtime --features http-server`
+- 必要に応じて `cargo test -p worker-runtime --features fs-store,http-server`
+- `cargo check -p yoi`
+- `git diff --check`
+- 可能なら `nix build .#yoi --no-link`
+
+Critical risks / reviewer focus:
+- Feature gating/dependency leakage。
+- REST handler が Runtime semantics を複製すること。
+- Browser direct Runtime access や credential leakage。
+- WebSocket/SSE scope creep。
+- package.nix cargoHash / lock consistency。

+Routing decision: implementation_ready。
+
+Dependency `00001KVZBCQH4` worker-runtime core は done。以前の waiting-capacity reason だった FS store branch も done/merged/validated 済み。Ticket body / relations / workspace state / accepted plan を確認し、REST command server slice は unblocked と判断した。
