Systemic audit gap:
Systemic audit gap: health checks are radically insufficient — starts does NOT equal works. Three bugs shipped (12-14 Mar 2026) because quality audits stopped at container starts, health responds 200: (1) PromQL rules used up{job=paperclip} — metric does not exist, false-positived. (2) SQL referenced a.label — column does not exist, 500 on real data. (3) asyncpg $2 mixed type context — works in psql, crashes in asyncpg. All passed health checks. Fix: Stage 2b Functional Smoke Tests mandatory for every change type. Pristine Sweep Category 8: Live System Verification. Rule: Container starts is infrastructure. Feature works with real data is verification. Both required. Every deployment MUST include real-data smoke test.
