some title

Quick read of the pattern: schema-guard now passes (the label fix worked), but lint, test, and typecheck went red after the rebase, and all three failing together in ~10 seconds usually means one mechanical cause (the rebase re-ran checks against a fresh base where something like the lockfile, a config, or an install step doesn't resolve), not three separate bugs. This is exactly the kind of thing the agent fixes in one pass once it reads the logs, which I can't see from here but it can.
