Overview / Motivation

Auto-filed by the /daily Step C parked-candidate sweep (2026-07-28) from a formal candidate block parked on task #1780 (ts 2026-07-29T03:11:33Z, fp e0e2756cfae6; source: orchestrator-own-observation, hit live during #1780's Step 10d).

Goal

Fix two ad-hoc-rediscovered defects in the Step 10d post-merge stale-task-folder guard's scratch-worktree removal recipe: (a) the sparse cone omits scripts/hooks, so the removal commit's own pre-commit hook exits 127 and the first attempt always fails; (b) the local-residue check flags EMPTY leftover directories that root syncs can never clear (rmdir is the correct disposition).

Workflow gap

Bug observed: the recipe sets the sparse cone to the duplicate task folders ONLY, so the pre-commit gitleaks hook (bash scripts/hooks/gitleaks_scoped.sh, worktree-root-relative path) exits 127 (No such file or directory) and the removal commit fails on the first attempt; observed live on #1780 (2026-07-29 ~03:08Z), retry with scripts/hooks in the cone passed cleanly. Additionally the ls -d local-residue check flags empty leftover dirs (git removes tracked files but leaves empty dirs), which two root syncs can never clear.
Why it is a workflow gap: every future guard firing re-discovers both fixes ad hoc — the documented recipe is wrong on both counts.
Confidence (emitter): high
verified-at-filing: grep -n 'sparse-checkout set "${DUPES[@]}"' .claude/skills/issue/SKILL.md → 1 hit (line 13067, without scripts/hooks) (2026-07-29 UTC). Landed-fix history check: git log --oneline --since='7 days ago' -- .claude/skills/issue/SKILL.md → no commit touching the scratch-worktree cone recipe. unverified hypothesis — verify at plan time: that the pre-commit config invokes scripts/hooks/gitleaks_scoped.sh by worktree-root-relative path (read .pre-commit-config.yaml at plan time; recalled from the live #1780 failure).

Proposed change (candidate diff sketch — refine in planning)

-       && git -C "$SCRATCH" sparse-checkout set "${DUPES[@]}" \
+       && git -C "$SCRATCH" sparse-checkout set "${DUPES[@]}" scripts/hooks \

And extend the local-residue tail: when ls -d still matches after 2 syncs, probe find <dup> -type f | wc -l; 0 files → find <dup> -depth -type d -exec rmdir {} \; (empty-dir residue, inert to git) instead of failing loud.

Scope / surfaces

Primary target: .claude/skills/issue/SKILL.md (the Step 10d scratch-worktree removal block)
Check whether any other scratch-worktree recipe in the workflow surface shares the cone omission: grep -rn 'sparse-checkout set' .claude/ scripts/.

Constraints / invariants

The guard's refuse-on-real-content behavior is unchanged — only the hook-cone and the empty-dir disposition change.
Workflow-surface only; recursion guard applies to the spawned session.

target_file: .claude/skills/issue/SKILL.md bug_observed: The Step 10d post-merge stale-task-folder guard's scratch-worktree removal recipe sets the sparse cone to the duplicate task folders ONLY, so the pre-commit gitleaks hook (entry bash scripts/hooks/gitleaks_scoped.sh, path relative to the worktree root) exits 127 (No such file or directory) and the removal commit fails on the first attempt; the guard reports staging FAILED and burns a retry. Observed live on task #1780 (2026-07-29 ~03:08Z); the retry with scripts/hooks added to the cone passed cleanly. Additionally, the guard's local-residue ls -d check flags EMPTY leftover directories (git removes tracked files on rebase/checkout but leaves empty dirs), which two root syncs can never clear — a file-count probe + rmdir is the correct disposition. why_workflow_gap: The documented recipe's sparse-checkout set "${DUPES[@]}" line omits the hook-script dir the commit's own pre-commit hooks need, and the local-residue tail's remedy (root syncs) cannot remove untracked empty dirs, so every future guard firing re-discovers both fixes ad hoc. proposed_change: In the SKILL.md scratch-worktree block, change the cone line to git -C "$SCRATCH" sparse-checkout set "${DUPES[@]}" scripts/hooks (one token), and extend the local-residue tail: when ls -d still matches after 2 syncs, probe find <dup> -type f | wc -l; 0 files → find <dup> -depth -type d -exec rmdir {} \; (empty-dir residue, inert to git) instead of failing loud. confidence: high related_task: #1780
