Resume this project from the repo-local handoff state. ## Current repo state ```! git status --short 2>/dev/null || echo "(not a git repo)" ``` ```! git log --oneline -12 2>/dev/null || echo "(no git log)" ``` ## Instructions Check for `.ai/HANDOFF.md`. Two paths: **If found:** Read it, along with `CLAUDE.md` and `AGENTS.md` if present. Then verify it against current repo state: confirm the branch matches, check that referenced files exist, and flag any commits more recent than the handoff that aren't reflected in it. If `.ai/reviews/` exists, note the most recent review report and surface any of its unresolved findings that bear on the next action. **If not found:** Tell the user explicitly that no handoff was found before doing anything else. Then reconstruct best-effort from the repo: scan recent git log, read recently modified files, and check for obvious entry points (scripts, notebooks, configs). ## Report State on the first line whether the handoff was loaded: `Handoff loaded from .ai/HANDOFF.md` or `No handoff found — reconstructed from repo.` Then open with a 2–3 sentence conversational recap — what this project is, what was being worked on, and where things stand. Write it the way a colleague would catch someone up after they've been away, not as a bullet list. Then follow with only the sections that have real content: **Key decisions** — consequential choices already locked in. **Scientific context** — datasets, baselines, reference periods, counterfac...
