 ## Outcome
 
-- Not completed.
+- Source `54aa426` (height product `66cad87`) merged without conflicts into fetched main `8a48246`; merge commit `00cd3c1`. Clean primary main was fast-forwarded to the tested merge. Latest colored teacher shortcuts and existing product behavior retained. No remote push or live-app mutation.
 
 ## Verification
 
-- Not run.
+- Pinned pnpm 10.33.4 standard typecheck, 91 tests across three teacher/composer unit files, changed TypeScript ESLint, production build and git diff --check passed. Two real-component Chrome tests at 319/508px passed after the merge (6.9s), checking empty/1/3/6/8 rows, height/bottom within 1px, no overflow, saved model send semantics and microphone/send-only controls. Screenshots independently inspected under `/tmp/merge-composer-height-browser-73ac902f`; test server stopped. Logs `/tmp/merge-composer-height-{typecheck,unit,lint,build}.log`.
 
 ## Follow-ups
 
-- None recorded.
+- Local main contains the source result and final merge record. Current managed merge checkout is clean/committed and approved for immediate official retirement from the primary checkout after final fast-forward. Keep its branch and commit; no additional project change remains.

 - Read AGENTS, entry, memory index, own record, positioning, current integrated snapshot, decisions/teacher ADR, architecture, domain/success criteria, evidence/reflection/commitment indexes and source outcome. Shared memory is historical; README, actual Git state and current explicit user instructions govern this presentation-only merge. No canonical reconciliation or semantic decision changes are required.
 - Fetched origin: main and origin/main both `8a482465d9ded9ae612c515513fc61d687a441e5` at task start, including latest colored shortcut styling. Merge-tree preview with source `54aa426` succeeds without conflicts. Relevant product boundary remains Renderer presentation; Main owns conversation state, requests and runtime.
 - Read-only review of all 27 other registered task records found no semantic conflict. Sidebar task can overlap CSS but has independent navigation behavior. The old child-language planning record is unspecified and unrelated. Preserve all active/reused worktrees.
-- Confirmed from this conversation's previous cleanup final that the retained checkout is `20260929-merge-composer-actions-23414dc2`, now reused by this task's height source. Its unmanaged flag reflects the known creation-registration failure. User now explicitly requests removal of that previously retained directory; perform manual eligibility review without changing its managed flag. The older window-close directory has since been reused by other work and is not automatically a cleanup candidate.

User now explicitly requests removal of that previously retained directory; perform manual eligibility review without changing its managed flag. Further read-only review corrected an initial assumption about the older window-close directory: its HEAD was an existing upstream commit at creation, not evidence of reuse; it has no owner or later reflog activity. The active sidebar task uses a different directory, which is retained.

 ## Plan

 1. Merge source onto the fetched main base; verify scoped product diff, typecheck, relevant composer tests and production build.
 2. Fast-forward the clean main checkout only after rechecking current main/remote state; retain all branches/commits.
 3. Review process/dependency links and ignored files; use official retirement for managed checkouts. For explicitly requested legacy cleanup use verified Git worktree removal after official registry release when app archival cannot address this unattached checkout. Keep records of exact removed/retained paths.
+
+## Cleanup Review And Outcome
+
+- User explicitly requested deletion of earlier retained workspaces. App artifact list is empty, so no managed attachment exists for archive_worktree. Official retire still rejects the old composer checkout as unmanaged. This follow-up explicitly supersedes the earlier decision to retain that known legacy directory and authorizes reviewed cleanup. Did not edit registry flags to pretend it was managed.
+- Removed legacy source/old merge checkout `/Users/chillishark/Makelore 麦洛/.codex-worktrees/makelore/20260929-merge-composer-actions-23414dc2` after verifying HEAD `54aa426` is included in main, clean tracked/untracked state, ready source record, no running process/open files/trial scripts or symlink dependency, and ignored content limited to generated build/test output and a dependency symlink. Used official registry release then exact-path Git worktree removal. Source branch at `54aa426` and previous merge branch at `72218e0` remain.
+- Removed orphan legacy checkout `/Users/chillishark/Makelore 麦洛/.codex-worktrees/makelore/20260929-window-close-merge-a37b9e12`. It had no owner, dirty/ignored content or process dependency; its HEAD `f443f3b` is already in main and reflog shows no post-creation work. Corresponding branch/commit remain. The active sidebar checkout `20260929-empty-work-merge-39c633d0`, primary checkout and unrelated worktrees are retained.
+- Current merge checkout `/Users/chillishark/Makelore 麦洛/.codex-worktrees/makelore/20260930-merge-composer-height-73ac902f` has only generated build output/dependency link and no test server remaining. Authorized final retirement uses the official task-context retire command from primary after this record is committed and main updated; retain branch `codex/20260930-merge-composer-height-73ac902f-merge-composer-height`.
+- Documentation gate initially flagged the source task record introduced by the merge as foreign. Its bytes matched source `54aa426` exactly. Used the official same-task adoption flow for the user-authorized known source: temporarily soft-reset only this private merge HEAD while preserving index/worktree, register the staged source record, then restore the identical original merge commit. No source document, product tree, merge parent, public history or user file changed. Final task-aware drift gate passes.
