Tat-Tally Pre-Norfolk Deep Audit Complete (Session 36, 2026-03-14) Ran a comprehensive 6-track parallel audit of the entire Tat-Tally contest system. Tracks covered: Security & Auth, Data Integrity & Database, Frontend Code Quality (all 5 apps), Multi-Tenancy & Isolation, Deployment & Infrastructure, UX & Event-Day Resilience. RESULTS: 5 blockers, 22 should-fix, 9 nice-to-have. All Session 30-31 findings confirmed resolved with no regressions. BLOCKERS (fix before Norfolk): B1: seed-event Edge Function has zero authentication (bypasses all RLS, anyone can inject data) B2: Entrant app missing ErrorBoundary (highest-traffic app crashes to white screen) B3: Dockerfile doesn't install @tat-tally/shared package before app builds B4: CI workflow same issue as B3 B5: CORS wildcards on check-approaching and send-sms Edge Functions (missed in Session 34) KEY CROSS-TRACK PATTERNS: 1. Multi-tenancy isolation is frontend-only: x-event-id header never sent by any app, RLS NULL bypass makes event-scoped policies permissive. Safe for Norfolk (single event), must fix before multi-tenant production. 2. Error response handling gaps: Edge Functions leak Postgres internals, entrant app has no ErrorBoundary, admin/display ErrorBoundaries don't report to Sentry. 3. Build pipeline fragility: shared package not installed in Dockerfile or CI. 4. Event-day resilience gaps: display monitors don't refetch on reconnect, entrant submissions have no timeout, admin can edit frameworks during active scoring. NORFOLK VERDICT: Conditional GO. All 5 blockers fixable in one session. System is architecturally sound, load-tested at 522 VUs, and hardened against critical failure modes. Fix execution plan: 6 chats total. Chat 1: Blockers. Chats 2-5: Should-fix items split by domain (Infrastructure, Frontend, Security+DB, Multi-Tenancy RLS). Chat 6: Nice-to-have items.
