AI Price Radar v3.7.11 — Compact Crawler State

This patch removes an unused local crawler history path that inflated the production SQLite database to multiple gigabytes and made scheduled publication slower than its interval.

What changed

  • Stops creating and writing product_snapshots; PostgreSQL remains the source of public offer history.
  • Keeps the crawler's current candidates, matches, run summaries, and reviewed Dujiao candidates.
  • Uses the incremental carry-forward publisher for 10-minute LDXP inventory refreshes; hourly refreshes remain authoritative multi-source transactions.
  • Aligns release metadata on 3.7.11.

Validation

  • Crawler tests must confirm that successful scans still replace current matches without creating product_snapshots.
  • Compact publication tests and production preflight must pass.
  • Inventory entrypoint tests must confirm that external-source availability no longer gates LDXP-only refreshes.

Deployment

  • Follow docs/QUICK_DEPLOY.md and deploy only the v3.7.11 Tag after CI succeeds.
  • With all crawler timers stopped, replace the existing crawler SQLite file atomically with a validated compact copy that contains candidates, matches, scan_runs, and dujiao_candidates. Preserve the old file as the existing deployment rollback artifact.
