+### 2026-06-02 — backend@134d155, frontend@18af5dd — lazy-load PG-capable store Mongo fallbacks
+
+**Commits:** backend `134d155` (version `2.8.32`), frontend `18af5dd` (version `2.8.32`)
+**Touched:**
+- Backend: `src/services/config/configStore.ts`, `src/services/marketplace/reviewStore.ts`, `src/services/marketplace/shopSettingsStore.ts`, `package.json`, `package-lock.json`
+- Frontend: `package.json` version metadata only.
+**Why:** Continue removing MongoDB as a runtime dependency by making the already PG-capable config, review, and shop-settings stores avoid top-level Mongoose/model imports. Mongo fallback/backfill paths still lazy-load the legacy models when they are actually used, preserving rollback/mirror behavior.
+**Verification:** Backend `npm run typecheck`; backend `bash scripts/smoke/marketplace-core-postgres-backfill.sh` (static Jest checks passed; optional live dry-run skipped because `MIGRATION_MONGO_URL`/`MIGRATION_PG_URL` were not set); backend `npx jest __tests__/health-check-service.test.ts __tests__/telegram-service.test.ts __tests__/telegram-auth.test.ts --runInBand` rerun outside the sandbox after `MongoMemoryServer` hit local bind restrictions (16/16 passed); backend/frontend `git diff --check`.
+**Linked docs updated:** [[Postgres Runtime Cutover Status]]
