- .gitignore: ignore root tmp/ (temp/ and .claude/tmp/ were already ignored;
root tmp/ was not, which is how scratch got committed and needed cleanup).
- New .claude/scripts/tmp-promotion-check.sh: advisory, read-only, never blocks.
Scans the gitignored scratch dirs (tmp/, temp/, .claude/tmp/) and flags files
worth graduating (scripts, substantial docs, session-log-referenced) before
they're lost to cleanup. Silent when scratch is empty.
- /save (Phase 4) and /scc (new step 2) run the check before sync.sh, pointing
at .claude/TEMP_GRADUATION.md for the graduate-vs-delete decision.
