State changed

Ticket を workspace-panel が queued にしました。

Decision

Routing decision: blocked_pending_dependency

Panel Queue により routing 対象として確認したが、00001KVHR3WRY は 00001KVHR3WRF に depends_on している。00001KVHR3WRF はまだ queued で未実装のため、この Ticket は実装開始せず queued のまま保持する。

Next:

• 00001KVHR3WRF が closed になった後、改めて reroute する。

Decision

Routing decision: implementation_ready

Reason:

• Panel Queue により、この Ticket は Orchestrator routing 対象として明示許可された。
• 前回は 00001KVHR3WRF local stdio config/trust policy が未完了だったため blocked/queued hold としたが、現在 00001KVHR3WRF は closed。
• Ticket body は stdio JSON-RPC lifecycle client の scope を initialize/capability negotiation/shutdown/process diagnostics foundation として明確に定義し、ToolRegistry/tools/resources/prompts exposure は non-goal として分離している。
• 現在 inprogress は 0 件、child implementation Pods はなし、matching branch/worktree はなし、Orchestrator worktree は clean。
• Risk domain は mcp / stdio / json-rpc / process-lifecycle / diagnostics だが、Ticket は explicit config only、bounded stderr diagnostics、safe shutdown/kill fallback、sampling/elicitation not advertised、no tools/resources/prompts registration などの invariants を明示している。bounded context check 後も implementation 前に必要な追加 human decision は見つからなかった。

Evidence checked:

• Ticket 00001KVHR3WRY body / thread / relations / artifacts。
• TicketRelationQuery(00001KVHR3WRY): outgoing depends_on 00001KVHR3WRF is now closed。Incoming 00001KVHR3WS6 / 00001KVHR3WSN are downstream and not blockers。
• TicketOrchestrationPlanQuery(00001KVHR3WRY): previous blocked_by 00001KVHR3WRF is resolved; accepted plan recorded now。
• Workspace state:
  • Orchestrator worktree clean at 8f5eef94。
  • queued: remaining MCP chain Tickets。
  • inprogress: 0。
  • visible Pods: self + peers only; spawned children 0。
  • no matching MCP lifecycle branch/worktree。

IntentPacket:

Intent:

• Implement a local stdio MCP lifecycle client foundation that can spawn an explicitly configured local server, exchange newline-delimited JSON-RPC on stdin/stdout, run initialize/capability negotiation, send notifications/initialized, and shut down safely。
• This Ticket must not expose MCP tools/resources/prompts to the model-visible ToolRegistry; it only provides the lifecycle/protocol substrate for later Tickets。

Binding decisions / invariants:

• Only explicit named config from 00001KVHR3WRF can be used; no implicit discovery or auto-start from workspace/package presence。
• Treat stdout as protocol messages and stderr as bounded diagnostics/logging, not automatic protocol failure。
• Bound stdout/stderr lines, diagnostics, protocol payloads, startup timeout, request timeout, shutdown timeout, and kill fallback。
• Include server name and startup phase in errors/diagnostics。
• Do not advertise sampling or elicitation client capabilities; if server requests them, fail closed / return an error as appropriate。
• Do not register tools/resources/prompts or expose any ToolRegistry surface in this Ticket。
• No remote MCP / Streamable HTTP / OAuth。
• Preserve trust boundary: local stdio server process runs as user OS executable; config validation is not sandbox authority。
• Secret/env values from config must remain redacted in diagnostics/logs/errors。

Requirements / acceptance criteria:

• Mock local stdio MCP server initializes successfully。
• Initialize failure reports server name and phase。
• Stderr is bounded and redacted where needed。
• Shutdown is safe and deterministic, with terminate/kill fallback。
• Sampling/elicitation are not advertised and fail closed if requested。
• No tools/resources/prompts are registered by this Ticket。
• Tests use local mock MCP server processes and cover success/failure/shutdown/diagnostic paths。

Escalate if:

• Existing runtime boundaries make it unclear where lifecycle client should live without dragging ToolRegistry or Plugin feature authority into the config layer。
• Protocol message typing requires a broad MCP provider substrate redesign。
• Deterministic process tests are infeasible without an explicit test harness decision。

Next action:

• Record queued -> inprogress and commit Ticket records before creating the implementation worktree and spawning Coder。

---

State changed

Ticket body/thread, relation metadata, closed MCP config dependency, Orchestrator worktree state, visible Pods, existing branch/worktree, and bounded MCP lifecycle context were checked. Dependency 00001KVHR3WRF is closed, no inprogress/capacity blocker exists, and no missing planning decision was found. Accepting this queued Ticket for implementation before worktree/Pod side effects.

Implementation report

Implementation orchestration start:

• Acceptance records were committed on Orchestrator branch: c0e760d7 ticket: accept mcp stdio lifecycle client。
• Created implementation worktree /home/hare/Projects/yoi/.worktree/00001KVHR3WRY-mcp-stdio-lifecycle-client on branch impl/00001KVHR3WRY-mcp-stdio-lifecycle-client at c0e760d7。
• Spawned Coder Pod yoi-coder-00001KVHR3WRY with write scope limited to the implementation worktree and read-only root scope only for runtime workspace identity。
• Coder task explicitly forbids root/original workspace implementation, ToolRegistry/tools/resources/prompts exposure for this Ticket, merge, Ticket close, and cleanup。

Next action:

• Wait for Coder implementation report, then inspect branch diff/validation evidence and route to Reviewer。
