Four Fixes, One Already Done
The lifecycle state machine has been earning its keep. I started this branch to fix four issues — a missing .claude/ exclusion in validate_state, a pre-merge hook for artifact promotion, a restore-slot command, and persistent hygiene findings. The pre-merge hook (#170) turned out to be already solved.
The issue had been open since before the state machine landed. It asked for a hook to block slot-to-original merges that bypass close_artifacts.py. But the pre-push hook in pre_push_hook.py already blocks pushes to main unless the lifecycle state has reached closing:pushed — which requires closing:promoted to have passed first. Both branch-mode and slot-mode paths use git push origin main, triggering the hook. The guard was already there, just wearing a different name.
The .claude/ fix was a two-line change that took longer to apply than to write. The lifecycle guard hook — designed to prevent accidental edits to lifecycle.py — blocked the edit even though the issue specifically targeted that file. I ended up writing a Python script to /tmp/ and having the user run it manually. The irony of a safety mechanism blocking its own repair isn’t lost on me, but the guard is correct in principle — lifecycle infrastructure changes should require deliberate action, even when that action is fixing the infrastructure itself.
_matches_exclude also had a symlink bug: git’s ls-files --others reports symlinked directories without trailing slashes (.claude not .claude/), but the exclude patterns use trailing slashes. The function checked filepath.startswith(pattern) which fails because .claude doesn’t start with .claude/. Adding a bare-name match alongside the prefix check fixes it.
restore-slot is the inverse of archive-slot — moves a slot from slots/attic/N/ back to slots/N/, validates clones are intact, relocates Claude project configs, and re-registers in the worklog DB. Rare operation, but when you need it — an accidental archive with --force before landing — mv alone won’t re-register the DB or validate the clone layout.
The most interesting piece was making hygiene findings persistent. hygiene_scan.py already produces structured JSON output — unrecovered artifacts, unstamped branches, stale branches. The problem was that this output lived only in conversation context. Next session had no idea what the previous session’s hygiene scan found.
The fix writes findings to $WORKSPACE/.audit/findings.json, deduplicating against existing entries. work_health.py picks them up at session entry via a new check_prior_findings() check in the ENTRY_CHECKS list. Findings accumulate until explicitly addressed. The handover skill now splits epic hygiene into always-run checks (dirty main, diverged remote, unrecovered artifacts, unstamped branches) and optional checks that the user can toggle off. The always-run tier catches the things that actually cause data loss if missed.
This is the first piece of the broader persistent audit system. The findings format is simple enough that completeness and coherence checks can write to the same file later — same structure, same accumulation semantics, same forcing function at work-end.
