B. Architecture Review

Critical Issues Identified (from PLAN.md)

  1. No idempotent ingestion (character-based chunking, no deterministic IDs)
  2. No reservation billing (revenue loss risk)
  3. Incomplete RLS plan (missing new tables)
  4. Deprecated x-admin-key still in use
  5. No scraper dedupe/canonicalization
  6. No cost control, caching, or circuit breakers in chat
  7. README outdated with deprecated examples
  8. No request-ID propagation
  9. No API-level rate limiting

Sonnet Task List (23 tasks, S1-S22 + S9b)
