 - Outcome: main fast-forwarded from 39b03a1628bcdbc9c6bcf82b874e2814bf1780d0 to a10cf000157a1a3edcfad43705e0824f19568a33 without conflicts. Product, tests, README and the imported source task record exactly match source. Only this integration record, teacher ADR, system overview and current-state were updated afterward; source records remain read-only.
 - Verification: source ancestry and exact product/source-record diff passed. Reused source 305 related unit tests, later 53 affected hook/UI tests and 1 newly added focused draft regression, 17 browser layout cases, 1 real Electron fixture interaction, Renderer typecheck, scoped ESLint and Vite all-target build. These are separate runs, not a claim that the final 306-case suite was rerun. No production provider or installed-client acceptance; existing Main strict-typecheck baseline is not changed.
 - Accepted promotions: direct server-agent titlebar entries, per-agent draft/history selection, horizontal overflow and removal of the agent dropdown. Historical topic versions, student billing and local read tools unchanged. No new semantic conflict.
-- Follow-up: source checkout remains pending separate cleanup consent; branch and commit must be preserved if retired. Earlier rendering-checkout cleanup remains pending. No push, packaging, installation or deployment performed.- Final gate: official task-aware documentation drift and git diff --check passed; the three adopted foreign documents remain unchanged and excluded from staging.

+- User explicitly approved retirement of 20260924-consultation-topbar-22717e99 at its named absolute path. Same integration task resumed; Concurrent and Planning Gates Passed using unchanged context and refreshed ownership, source cleanliness, committed readiness and exact source-in-main evidence. Plan: official retire from main, verify directory removal and branch preservation, record outcome and complete. Other worktrees and three adopted documents remain untouched.
+- Outcome: official retire failed with Git's "Directory not empty" error. Git already removed the source checkout's .git marker and worktree-list entry; residual files remain at the exact approved path. The source branch still resolves to a10cf000157a1a3edcfad43705e0824f19568a33, which is included in main. No manual registry change or residual-file deletion was performed.
+- Cleanup follow-up is Blocked pending the specifically requested recovery approval: remove residual files at the same approved path with native PowerShell, then official release-missing --force for this exact task. This does not invalidate the completed integration; other task worktrees and three foreign documents remain untouched. No application tests are needed for this administrative-only follow-up.
+
+- Recovery approval received for native removal of the exact residual directory and official release-missing. The execution environment's automatic approval rejected that deletion command before process creation ("blocked by policy", no more specific reason supplied). Neither residual removal nor release-missing ran. Cleanup is now Blocked by execution policy, not missing user consent; do not repeat the deletion using a bypass. The source branch and main integration remain intact.
