-`review/review-poll.sh` — Cron scheduler: finds unreviewed PRs with passing CI. Sources `lib/guard.sh` and calls `check_active reviewer` — skips if `$FACTORY_ROOT/state/.reviewer-active` is absent. **Circuit breaker**: counts existing `<!-- review-error: <sha> -->` comments; skips a PR if ≥3 consecutive errors for the same HEAD SHA (prevents flooding on repeated review failures).
-`review/review-pr.sh` — Creates/reuses a tmux session (`review-{project}-{pr}`), injects PR diff, waits for Claude to write structured JSON output, posts markdown review + formal forge review, auto-creates follow-up issues for pre-existing tech debt. **cd at startup**: changes to `$PROJECT_REPO_ROOT` early in the script — before any git commands — because the factory root is not a git repo after image rebuild (#408). Calls `resolve_forge_remote()` at startup to determine the correct git remote name (avoids hardcoded 'origin'). Before starting the session, runs `lib/build-graph.py --changed-files <PR files>` and appends the JSON structural analysis (affected objectives, orphaned prerequisites, thin evidence) to the review prompt. Graph failures are non-fatal — review proceeds without it.
