Second review round: - createMeiliSink applies the index settings once before its first write, so a fresh-rollout 'pnpm backfill' (or reindex) can't auto-create a bare index whose _geo/startsAt filtered searches 400. Flag flips only on success so a transient Meili outage retries instead of disabling the sink. (TDD'd.) - meili:reindex:remote: clarify it resolves the D1 binding exactly like the pre-existing backfill:remote (same wrangler env.production), and log which D1 (local vs deployed) is targeted before connecting. - prettier: format README.md, contrail.config.ts, contrail.config.test.ts (were committed unformatted).
