소유자 목표: 운영 세션834513b3 요청 「동적 경로의 등급 페이스가 풀리지 않는 원인을 찾는다. 경로 모델 순서는 소유자 결정이니 바꾸지 않는다. 실패 시 다음 후보로 넘기는 처리를 고친다.」
확인할 결과: 검토 등급의 장시간 starting/tier_pace 대기 원인이 실제 흐름·상태 근거로 밝혀지고, 모델 순서를 보존하며 실패 후보가 다음 후보로 넘어가는 처리의 문제 여부와 최소 수정 결과가 정상 fork 검토·병합 절차로 전달된다.
이 작업 몫: tier_pace 정체 한 건의 원인 조사 및 입증된 같은 결함의 최소 수정. 조사 후 W08291731510 정리 방법을 부모에 전달한다.

Supplied observations: W082 taskd081c10a-f451-4fca-bd4c-145c3b4746e2 review session91731510-6aea-4a4e-af3b-436363b6e7f7 CREATED since2026-10-10T09:04:25Z, reported route_state=starting/route_reason=tier_pace. Standing native read confirms that session is still CREATED and is not current primary (ccede198 WAITING_FOR_INPUT); W082 task is REVIEW/Hold. AIWS W1010-10 review session prefixb1031062 reportedly same from15:50Z; operations stopped it18:11Z and reopened its column, now manual_move_lifecycle_pending without new session. These are reported incident facts; do not invent full AIWS UUID, causal equality or a no-loss claim.
Trace actual pacing state/deadline/admission/reconciliation/candidate failure→next-candidate lifecycle, including session/step binding and whether manual_move_lifecycle_pending is separate. Check existing local requirements/designs, prior W26 ceiling/step/session drift and earlier W055 argument-loss/W084 entry-binding context only where relevant. Existing W26 is AIWS/Ops-owned; link causal evidence to it instead of duplicating that incident. Office/API generation failure and tier_pace may differ: establish ownership at the responsible boundary. No guessed cause, blanket fix or replay of stale observations.
Use existing debug/fix/planning and reviewed contracts. Produce root cause, impacted boundary and a reviewable minimum plan in this task before production changes. Preserve the user's exact ordering and fallback semantics. Once the same defect is demonstrated and scope is reconciled, follow normal formal workflow gates for minimum repair and source-adjacent changed-logic unit tests; no new permanent integration/e2e framework/CI, full suite or general routing redesign. Material model/behavior/permission changes need parent decision; changing model order, pinning a cheaper substitute, increasing ceiling, retrying quota forcibly, cancellation/restart workaround or creating duplicate sessions is prohibited. Actual capacity deferral is not fixed by cancelling unrelated work.
Diagnostics: worker may inspect assigned worktree source and existing bounded incident artifacts; operating API/task/session reads and SQLite only through explicitly read-only mode=ro when genuinely necessary for this diagnosis. No operating DB write/migrate/VACUUM/locks/settings/profiles/circuit changes. No live instrumentation/debug-env enabling/artificial stall/new provider call. Cross-workspace AIWS action and unavailable original log/full session identity are operations-owned inputs, requested through parent when needed; don't manipulate AIWS tasks or source promotion.
Design basis: design-card invariant3 (user-visible control), invariant4 (profile isolation), invariant5 (worktree isolation) at D:/260720_Ai_Workspace/projects/260926_Kandev/repo/_Prj_Knowledge/p200_index/설계카드.md:28-32, design index ARCHITECTURE.md §3 Orchestrator Service/§4 Agent Manager Service and existing durable session-concurrency/route pacing specs selected by actual ownership. Read relevant scoped AGENTS and only needed design sections in your own task worktree.
Execution: standing parent8e3eb6b7-f0fb-4d79-a954-69aeab00993a; explicit Worktree08eb0bba-37dc-459c-b34c-14322417bde7/new_workspace/repository068d4436-d120-42af-b178-8e1a45eb2279/forkmain. One assigned worktree, no shared/parent checkout writes, second worktree, reset--hard/force/unknown deletion. All fork PRs --repo dreampiler/kandev; upstream writes solely W091fixedOpus. Dynamic step routing selects models, no manual reorder/profile substitution.
W08291731510 must remain intact until cause/evidence capture is complete. Worker does not call stop_task(W082 would kill other sessions), move W082, start a replacement or delete the session. Report exact obsolete-session ownership/current state and minimal cleanup recommendation to parent; parent/operations perform only the authorized session-specific cleanup after investigation. Preserve W082 shared-impact Hold/original labels and230; no bulk cancellation. Never restore old stale Review or repeat already accepted reviews.
Completion: separate verified cause from hypothesis, exact incident source/time/status evidence, plan/fix/minimum validation and fork review/merge if needed, remaining live-data gap and next actor, explicit cleanup recommendation for91731510 after investigation. The independent sync W094 and operations replacement do not wait for this investigation unless it proves a concrete deployment blocker. Reporting via existing jobsheet KANDEV-W-095. No new ledger, monitor, heartbeat, paid call or unrelated audit.
