Prevents recurrence of the case-rename 500 (PR #249), whose root cause was an undefined name (`paperclip_client`) sitting in a background_tasks callable — invisible until that code path ran in production. - scripts/check_undefined_names.py: runs pyflakes on web/, mcp-server/src, scripts/ and fails ONLY on "undefined name" / "may be undefined" (the runtime-crash class). Unused imports / f-strings are NOT gated — keeps the check high-signal and green. - .gitea/workflows/lint.yaml: runs the guard on every PR and push to main, in a throwaway venv (PEP-668 safe). - db.py: `from datetime import date` → `date, datetime`. The guard surfaced a real latent undefined name — `insert_panel_round`'s `round_ts: datetime` annotation referenced an unimported `datetime` (benign only because of `from __future__ import annotations`; now correct). - SCRIPTS.md: documented the new guard. Verified: clean tree → exit 0; injected undefined name → exit 1. Invariants: engineering rule §6 (no silent failures shipping to runtime).
