 - `foundry-init.sh` — one-shot repo scaffold.
 - `setup-labels.sh` — create the GitHub labels the workflows + ticket state machine need (agent:ready/working/blocked, align, ruleset-change, autofix). Idempotent; run by `foundry-init`.
 - `foundry-pr-report` - one-shot, non-blocking PR check reporter: prints the bucket verdict for a PR's checks and, on failure, dumps the failing steps' logs via `gh run view --log-failed`; exits 0 (all passed/skipped), 1 (a check failed), or 2 (still pending). Trigger-agnostic by design, so a PR-authoring agent gets the actual failure text looped back without a blocking watch: call it once CI has finished, from whatever async trigger you wire up (a local post-push hook, a webhook-fired routine, or a background task that resumes the session). Needs `gh`.
