+# Task: Clean up stale branches and worktrees
+
+## Identity
+
+- Task ID: 20260907-cleanup-stale-branches-4e7a9c1d
+- Mode: Feature
+- Branch: main
+- Worktree: /Users/inmanx/Documents/makelore
+- Base commit: 860c97d466a9657061b6680d3a546b466e925cf9
+- Owner: codex
+- Status: Ready for integration
+
+## Scope
+
+- Inventory Makelore-linked worktrees and local branches under
+  `/Users/inmanx/Documents`, classify them against local `main`, and remove
+  completed or explicitly superseded local checkout history.
+- Release completed task-registry ownership before removing its worktree.
+- Keep the canonical `main` worktree, remote refs, historical user data, and
+  any unresolved unique product work outside the deletion set.
+
+## Intent And Constraints
+
+- Prefer `git worktree remove`, task-context release, and local branch deletion
+  over broad filesystem removal.
+- Treat branches whose tips are ancestors of `main` as integrated. Treat the two
+  remaining Learning source branches as explicitly superseded by the integrated
+  Learning removal and current Code/Canvas/Robot product boundary.
+- The five dirty historical worktrees contain only reviewed audit screenshots,
+  superseded concept task records, or an integrated Design QA report. The user's
+  explicit request to clean all expired history authorizes their irreversible
+  removal and the task registry's force-release recovery path.
+- Do not push, delete remote branches, rewrite `main`, change product code, or
+  delete historical application user data.
+
+## Outcome
+
+- Released all nine stale task-registry owners. Four clean source tasks used the
+  normal release path; five expired audit/concept worktrees used the explicitly
+  authorized force-release path after their untracked contents were classified.
+- Removed all 22 linked Makelore worktrees. The irreversible untracked deletion
+  set was six audit screenshots, one audit report, four superseded task records,
+  and one integrated `design-qa.md` report.
+- Deleted 31 local `codex/*` branch refs whose tips were ancestors of `main`.
+  Deleted the remaining two local Learning refs after confirming that the full
+  Learning removal is already integrated and the older Player branch is
+  superseded by the current Code/Canvas/Robot product decision.
+- Pruned worktree metadata and removed the now-empty repository `.worktrees`
+  container. The repository now has one worktree and one local branch: canonical
+  `main` at the original product head.
+- Removed about 21.0 GiB of stale Makelore checkout data. Remote refs, remote
+  state, product source, historical application user data, and `origin/main`
+  were not changed.
+
+## Verification
+
+- `git worktree list --porcelain`: only
+  `/Users/inmanx/Documents/makelore` at
+  `860c97d466a9657061b6680d3a546b466e925cf9` on `main`.
+- `git for-each-ref refs/heads`: only local `main` remains.
+- `task_context.py status --json`: only this cleanup task owns a worktree.
+- `task_context.py doctor`: passed; registry is consistent.
+- `git fsck --connectivity-only`: exited successfully. Deleted tips remain only
+  as expected unreachable/reflog objects until normal Git garbage collection.
+- Documents directory inventory: no Makelore task checkout directories remain.
+- No product files changed, so product tests/builds were not run.
+
+## Follow-ups
+
+- None for this repository. Normal Git maintenance may reclaim unreachable
+  objects after its retention window; no aggressive prune was run so unrelated
+  recovery data was not discarded.
+
+## Promotion Candidates
+
+- None. This is local repository maintenance with no product or architecture
+  change.
