 Ticket body/thread, relation metadata, orchestration plan records, related closed Tickets, Orchestrator worktree, visible Pods, existing branch/worktree, and bounded Plugin CLI/code context were checked. Depends-on blockers are closed, no dirty-state blocker or missing planning decision was found. Risk is captured as invariants/reviewer focus. Host API Tickets queued in the same pass were left queued with conflict/waiting records. Accepting this queued Ticket for implementation before worktree/Pod side effects.

+## Implementation report
+
+Implementation start note:
+
+`queued -> inprogress` acceptance、accepted plan、routing decision / IntentPacket、host API Tickets の waiting/conflict records を記録し、Orchestrator worktree で commit した後に、専用 implementation worktree と Coder Pod を起動した。
+
+Worktree:
+- `/home/hare/Projects/yoi/.worktree/00001KVFD3YSV-plugin-cli-inspection`
+- branch: `impl/00001KVFD3YSV-plugin-cli-inspection`
+
+Coder Pod:
+- `yoi-coder-00001KVFD3YSV`
+
+Scope / boundaries:
+- child runtime workspace root は read scope。
+- implementation worktree は write scope。
+- root/original workspace と Orchestrator worktree へは書き込まないよう指示済み。
+- `.yoi/memory`、runtime/log/lock/local/secret-like `.yoi` paths は編集しないよう指示済み。
+
+Related queued Tickets:
+- `00001KVFDX9AF` https host API and `00001KVFDX9AY` fs host API remain queued with waiting/conflict notes because their implementation touches overlapping Plugin runtime/grant/diagnostic surfaces.
+
+Next:
+- Coder は read-only Plugin CLI inspection、focused tests、validation、implementation commit を行い、実装報告を返す予定。
