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、00001KVHR3WSW は 00001KVHR3WS6 に depends_on している。list_changed handling は initial tools/list registration を前提にするため、00001KVHR3WS6 が closed になるまで実装開始せず queued のまま保持する。

Next:

• 00001KVHR3WS6 が closed になった後、改めて reroute する。

---

Decision

Routing decision: implementation_ready

Reason:

• User directive: 「blocker無いなら並列にやっちゃえよ」。現在 inprogress は 0 件であり、最後に残った queued Ticket の dependency blocker も解消済みのため開始する。
• 前回は 00001KVHR3WS6 initial tools/list registration が未完了だったため blocked/queued hold としたが、現在 00001KVHR3WS6 は closed。
• Related resources/prompts operations Ticket 00001KVHR3WSN も closed になっており、tools/resources/prompts list_changed をまとめて扱う context が揃っている。
• Ticket body は notifications/tools/list_changed, notifications/resources/list_changed, notifications/prompts/list_changed の handling、current run schema consistency、prompt-cache/history invariants、deterministic refresh/diagnostic behavior、unsafe refresh fallback を実装可能な粒度で定義している。
• Orchestrator worktree は clean、matching branch/worktree はなし。
• Risk domain は mcp / notifications / tool-schema / prompt-cache / refresh だが、Ticket は current run schema consistency、no hidden context mutation、bounded diagnostics 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 00001KVHR3WSW body / thread / relations / artifacts。
• TicketRelationQuery(00001KVHR3WSW): outgoing depends_on 00001KVHR3WS6 is now closed。
• TicketOrchestrationPlanQuery(00001KVHR3WSW): previous blocked_by 00001KVHR3WS6 is resolved; accepted plan recorded now。
• Workspace state:
  • Orchestrator worktree clean at b11f83c8。
  • queued: this Ticket only。
  • inprogress: 0。
  • spawned child implementation Pods: 0。
  • no matching MCP list_changed branch/worktree。

IntentPacket:

Intent:

• Handle MCP list_changed notifications without silently staying stale forever and without mutating active-run model-visible tool schema or prompt/context history invariants unsafely。
• Implement a deterministic safe-boundary refresh / restart-required diagnostic / next-turn refresh policy that covers tools/resources/prompts list changes。

Binding decisions / invariants:

• Do not mutate current LLM context with hidden resource/prompt content。
• Do not unexpectedly mutate active run tool schema in a way that breaks request/history/prompt-cache invariants。
• list_changed notifications are signals; they should produce bounded state/diagnostic and deterministic refresh behavior at safe boundaries。
• Bounded diagnostics should identify server and list kind without leaking secrets。
• Preserve existing explicit Tool operations for tools/resources/prompts。
• Do not implement remote transports, sampling, or elicitation。

Requirements / acceptance criteria:

• Handle notifications/tools/list_changed, notifications/resources/list_changed, and notifications/prompts/list_changed。
• list_changed does not silently stale forever。
• Current run tool schema consistency is not broken。
• Refresh/diagnostic behavior is deterministic and documented。
• Prompt-context/history invariants are preserved。
• Tests cover tools/resources/prompts list_changed and unsafe refresh fallback。

Escalate if:

• Safe refresh requires changing Worker history/model schema lifecycle beyond this Ticket。
• Current provider/feature architecture cannot represent pending refresh diagnostics without broad redesign。
• A live schema mutation would be required to satisfy the feature expectation; stop instead and record restart/next-turn policy。

Next action:

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

State changed

User explicitly authorized implementation when no blocker exists. Ticket body/thread, relation metadata, closed MCP tool-registration dependency, closed resources/prompts context, Orchestrator worktree state, visible Pods, existing branch/worktree, and bounded list_changed/schema/history context were checked. Dependency 00001KVHR3WS6 is closed, no inprogress/capacity blocker exists, no matching worktree/branch 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: d31b8907 ticket: accept mcp list changed handling。
• Created implementation worktree /home/hare/Projects/yoi/.worktree/00001KVHR3WSW-mcp-list-changed on branch impl/00001KVHR3WSW-mcp-list-changed at d31b8907。
• Spawned Coder Pod yoi-coder-00001KVHR3WSW 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, hidden context injection, unsafe active-run schema mutation, sampling/elicitation scope creep, merge, Ticket close, and cleanup。

Next action:

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