+# Dead Code Report — branch `DEAD_CODE_CLEAN`
+
+> **Status: EXECUTED.** The dead code listed below has been removed (see "Removal status" at the bottom). The one exception is the Drizzle relation exports, which were kept after verification.
+
+Static-analysis sweep for reachable-code / caller-less code across the monorepo.
+**Method:** ripgrep-based caller search + manual verification.
+
+- **tRPC endpoints:** every procedure in `admin`/`user`/`common` routers was enumerated, then searched for callers (`trpc.<path>` and `trpcClient.<path>`) in `apps/admin-ui`, `apps/user-ui`, `apps/web-ui`, `apps/admin-web`, `apps/fallback-ui`, `apps/info-site`.
+- **Methods/functions:** exported + local `function`/`const` definitions in `apps/backend/src` and `packages/db_helper_sqlite/src` were searched repo-wide; classified as *truly uncalled* only when they appear nowhere except their definition (and pure re-export files).
+- **Files:** inbound-reference scan by module name.
+- Excludes `node_modules`, `dist`, `.wrangler`, `.output`, `.expo`, `.turbo`, `.tanstack`.
+
+> Caveats at the bottom — some of these may be intentional (manual tooling, external API consumers, planned features). Verify before deleting.
+
+---
+
+## 1. Dead tRPC endpoints (15)
+
+No caller in any client app (native or web). Each is still registered on the router, so it is reachable over HTTP but unused by this repo.
+
+| Endpoint | File | Line | Note |
+|---|---|---|---|
+| `trpc.admin.coupon.validate` | `apps/backend/src/trpc/apis/admin-apis/apis/coupon.ts` | 265 | Admin coupon validation |
+| `trpc.admin.vendorSnippets.getById` | `.../admin-apis/apis/vendor-snippets.ts` | 184 | Single snippet fetch |
+| `trpc.admin.vendorSnippets.getVendorOrders` | `.../admin-apis/apis/vendor-snippets.ts` | 464 | Vendor orders |
+| `trpc.admin.slots.getSlotsProductIds` | `.../admin-apis/apis/slots.ts` | 138 | Dup of product.* variant |
+| `trpc.admin.slots.updateSlotProducts` | `.../admin-apis/apis/slots.ts` | 194 | Dup of product.* variant |
+| `trpc.admin.slots.getSlots` | `.../admin-apis/apis/slots.ts` | 387 | Only `trpc.user.slots.getSlots` is used |
+| `trpc.admin.slots.deleteSlot` | `.../admin-apis/apis/slots.ts` | 583 | No delete-slot UI |
+| `trpc.admin.product.updateSlotProducts` | `.../admin-apis/apis/product.ts` | 392 | Duplicate router entry |
+| `trpc.admin.product.getSlotsProductIds` | `.../admin-apis/apis/product.ts` | 462 | Duplicate router entry |
+| `trpc.admin.staffUser.getUsers` | `.../admin-apis/apis/staff-user.ts` | 79 | `admin.user.getAllUsers` is the used one |
+| `trpc.admin.staffUser.getUserDetails` | `.../admin-apis/apis/staff-user.ts` | 104 | `admin.user.getUserDetails` is used |
+| `trpc.admin.staffUser.updateUserSuspension` | `.../admin-apis/apis/staff-user.ts` | 128 | `admin.user.updateUserSuspension` is used |
+| `trpc.admin.user.createUserByMobile` | `.../admin-apis/apis/user.ts` | 29 | No caller |
+| `trpc.common.product.getDashboardTags` | `.../common-apis/common.ts` | 144 | Home reads tags from `products.json`, not this |
+| `trpc.hello` | `apps/backend/src/trpc/router.ts` | 14 | Scaffold sample endpoint |
+
+**Notable:** the `slots` ↔ `product` routers have **four duplicated** procedures (`getSlotsProductIds`, `updateSlotProducts`) — both copies are dead. The `staffUser` router duplicates three user-management procedures that are only ever called via the `admin.user` router.
+
+---
+
+## 2. Dead backend functions / constants (truly uncalled)
+
+Defined/exported but never referenced anywhere else in the repo.
+
+### Env / config
+| Symbol | File |
+|---|---|
+| `getJwtSecret` | `apps/backend/src/lib/env-exporter.ts` |
+| `getRedisUrl` | `apps/backend/src/lib/env-exporter.ts` |
+| `getPhonePeBaseUrl` | `apps/backend/src/lib/env-exporter.ts` |
+| `getPhonePeClientId` | `apps/backend/src/lib/env-exporter.ts` |
+| `getPhonePeClientVersion` | `apps/backend/src/lib/env-exporter.ts` |
+| `getPhonePeClientSecret` | `apps/backend/src/lib/env-exporter.ts` |
+| `getPhonePeMerchantId` | `apps/backend/src/lib/env-exporter.ts` |
+| `READABLE_ORDER_ID_KEY` | `apps/backend/src/lib/const-strings.ts` |
+| `WELCOME_MESSAGE` | `apps/backend/src/lib/const-strings.ts` |
+| `defaultRole` | `apps/backend/src/lib/roles-manager.ts` |
+
+### Notifications / jobs
+| Symbol | File | Note |
+|---|---|---|
+| `sendPushNotificationsMany` | `apps/backend/src/lib/expo-service.ts` | Whole file has no importers (see §4) |
+| `sendOrderPlacedNotification` | `apps/backend/src/lib/notif-job.ts` | Only an unused import + a commented call in `user-apis/order.ts` |
+| `sendOrderCancelledNotification` | `apps/backend/src/lib/notif-job.ts` | Same — imported, call commented |
+| `sendPaymentFailedNotification` | `apps/backend/src/lib/notif-job.ts` | No reference |
+| `sendOrderOutForDeliveryNotification` | `apps/backend/src/lib/notif-job.ts` | No reference |
+| `sendRefundInitiatedNotification` | `apps/backend/src/lib/notif-job.ts` | No reference |
+
+*(Alive: `sendAdminNotification` via `queue-consumer.ts` ← `worker.ts`; `sendOrderPackagedNotification` and `sendOrderDeliveredNotification` via admin order api; `scheduleNotification` via those.)*
+
+### Stores / cache / misc
+| Symbol | File |
+|---|---|
+| `getOrderDetailsWrapper` | `apps/backend/src/dbService.ts` |
+| `clearAllCache` | `apps/backend/src/lib/cloud_cache.ts` |
+| `getAllBanners` | `apps/backend/src/stores/banner-store.ts` |
+| `getTagById` | `apps/backend/src/stores/product-tag-store.ts` |
+| `getAllTags` | `apps/backend/src/stores/product-tag-store.ts` |
+| `getProductSlots` | `apps/backend/src/stores/slot-store.ts` |
+| `getAllProductsSlots` | `apps/backend/src/stores/slot-store.ts` |
+| `getUserNegativity` | `apps/backend/src/stores/user-negativity-store.ts` |
+| `createTRPCRouter` | `apps/backend/src/trpc/trpc-index.ts` (alias re-export, unused) |
+
+---
+
+## 3. Dead exports in `db_helper_sqlite`
+
+| Symbol | File | Note |
+|---|---|---|
+| `mergeDuplicateProducts` | `packages/db_helper_sqlite/src/admin-apis/merge-duplicate-products.ts` | Exported via index + `sqliteImporter`, but **no code calls it** (function had a "how to use manually" doc comment → manual utility). **Removed.** |
+
+`productSkusRelations`, `productMarketStatsRelations`, `skuFeaturesRelations`, `productCombosRelations` (`src/db/schema.ts`) looked unreferenced but are **NOT dead** — Drizzle registers relation exports via `import * as schema` in `db_index.ts`, and `db.query.*.findMany({ with: … })` depends on them. **Kept.**
+
+Used only inside their own file (helpers of live code — **not dead**): `parseDuplicateProductsMd` (deleted with the merge utility), `splitQuantityFeature`, `cleanFeatureValue`, `productTypeEnum`.
+
+---
+
+## 4. Dead / unreachable files & endpoints
+
+| Item | File | Note |
+|---|---|---|
+| Expo push service | `apps/backend/src/lib/expo-service.ts` | No module imports it; its only export is uncalled |
+| `av-router` | `apps/backend/src/apis/admin-apis/apis/av-router.ts` | Mounted at `/api/v1/av` but registers **zero routes** (staff-auth middleware only) |
+| REST product summary | `apps/backend/src/apis/common-apis/apis/common-product.controller.ts` (`getAllProductsSummary`) | Reachable at `/api/v1/cm/products/summary`, but **no client calls it** (apps use tRPC) |
+
+`/api/test` (`test-controller.ts`) is referenced only by `apps/fallback-ui/src/routes/demo.tsx` (a demo page).
+
+---
+
+## 5. Unused imports that point at dead code
+
+| File | Unused import | Reality |
+|---|---|---|
+| `apps/backend/src/trpc/apis/user-apis/apis/order.ts` | `sendOrderPlacedNotification` (line 29) | Call is commented out (line 235) |
+| `apps/backend/src/trpc/apis/user-apis/apis/order.ts` | `sendOrderCancelledNotification` (line 30) | Call is commented out (line 598) |
+
+---
+
+## 6. Commented-out / unreachable code blocks
+
+Not "callers-less" but unreachable. Many "Old implementation" blocks were kept across the backend; the most notable registered-looking ones:
+
+- `apps/backend/src/trpc/apis/common-apis/common.ts:160-176` — `getStoresSummary` and `healthCheck` procedures inside a `/* … */` block (NOT registered; the live ones are in `common-trpc-index.ts`).
+- `apps/backend/src/main-router.ts` — `// router.route('/av', avRouter)` (route disabled).
+- Numerous `// Old implementation - direct DB queries:` blocks in `admin-apis/*`, `user-apis/*`, and db helpers (historical only).
+
+---
+
+## 7. Checked and NOT dead (for reference)
+
+- `apps/admin-ui` / `user-ui` / `web-ui` exports: **0 truly-unused**. 18 shared exports (`AdminOrderItemCore`, `SkuFlagCore`, `UserStoreSummaryCore`, …) are referenced only within their own file to compose other types — that's normal, not dead.
+- Backend functions used only inside their own file (e.g. `cloud_cache` internals `createProductsFileInternal`, `constructCacheUrl`, `clearUrlCache`; `slot-store` `transformSlotToStoreSlot`/`extractSlotInfo`/`fetchAllTransformedSlots`; `trpc-index` `createCallerFactory`) — all reachable via their parent functions, **not dead**.
+- `queue-consumer.ts` — although it imports only-in-backend, it IS used by `worker.ts`, so alive.
+
+---
+
+## Caveats
+
+1. **Static analysis only.** A tRPC procedure can still be called by an external/undisclosed client (mobile build, partner integration). Confirm before removing public procedures.
+2. **`mergeDuplicateProducts`** and **`expo-service`** look intentionally kept for manual/one-off use — decide whether to delete or document.
+3. The `admin-web` tree is present on disk but **untracked** on this branch; it was included in the caller search.
+4. Some "dead" management procedures (`staffUser.*`, duplicated `slots`/`product` entries) may be leftovers from older UI screens; safe to remove once confirmed.
+
+## Removal status (executed)
+
+**Removed — 15 tRPC procedures:** `admin.coupon.validate`; `admin.vendorSnippets.getById`, `getVendorOrders`; `admin.slots.getSlotsProductIds`, `updateSlotProducts`, `getSlots`, `deleteSlot`; `admin.product.updateSlotProducts`, `getSlotsProductIds`; `admin.staffUser.getUsers`, `getUserDetails`, `updateUserSuspension`; `admin.user.createUserByMobile`; `common.product.getDashboardTags`; `trpc.hello`.
+
+**Removed — backend functions/constants:** `getJwtSecret`, `getRedisUrl`, `getExpoAccessToken`, `getPhonePeBaseUrl/ClientId/ClientVersion/ClientSecret/MerchantId`, `READABLE_ORDER_ID_KEY`, `WELCOME_MESSAGE`, `defaultRole`, `getOrderDetailsWrapper`, `clearAllCache`, `getAllBanners`, `getTagById`, `getAllTags`, `getDashboardTags`, `getProductSlots`, `getAllProductsSlots`, `getUserNegativity`, `createTRPCRouter`, `createCallerFactory`, and the notification senders `sendOrderPlacedNotification`, `sendPaymentFailedNotification`, `sendOrderOutForDeliveryNotification`, `sendOrderCancelledNotification`, `sendRefundInitiatedNotification` + their message constants.
+
+**Removed — DB helper functions orphaned by the procedures above (from BOTH `db_helper_sqlite` and `db_helper_postgres`, plus their barrel exports and `sqliteImporter` re-exports):**
+`createUserByMobile`, `deleteSlotById`, `getVendorOrders`, `updateSlotProducts`, `getSlotsProductIds` (the five behind the deleted endpoints) **and** `getActiveSlots`, `getAllUsers`, `getUserWithDetails`, `validateCoupon`, `checkUnitExists`, `getProductImagesById`, `replaceProductTags` (same class, missed by the first scan because their names also exist in the parallel package).
+
+**Removed — files:** `apps/backend/src/lib/expo-service.ts`, `apps/backend/src/middleware/staff-auth.ts` (only used by the empty `av-router`), `apps/backend/src/apis/admin-apis/apis/av-router.ts` (empty router), `packages/db_helper_sqlite/src/admin-apis/merge-duplicate-products.ts`.
+
+**Removed — wiring:** `avRouter` import/route from `main-router.ts` + `v1-router.ts`; `mergeDuplicateProducts` exports from `db_helper_sqlite/index.ts` and `sqliteImporter.ts`; unused `sendOrder*Notification` import + commented calls in `user-apis/order.ts`; orphaned imports in all touched files.
+
+**Kept (false positives / intentional):** the four Drizzle relation exports (implicitly registered); `mergeDuplicateProducts` was deleted per §3.
+
+**Verification:** `tsc` clean for `apps/backend`, `packages/db_helper_sqlite`, `apps/web-ui`, `apps/admin-ui`, `apps/user-ui`, `apps/admin-web`. (`apps/fallback-ui` has one pre-existing `vite.config.ts` error unrelated to this change.)

-/**
- * merge-duplicate-products.ts
- *
- * Merges duplicate products (the same item entered as separate product_info rows)
- * into single products with multiple SKUs.
- *
- * The merge groups are defined by PRODUCT NAME, sourced from
- * docs/duplicate-products-local_8_aug.md — not by hardcoded ids. The md's
- * "Clear duplicates" section is embedded below (DUPLICATES_MD) and parsed at
- * module load; GROUPS_TO_MERGE decides which sections actually get merged.
- *
- * For every selected group this function:
- *   1. Resolves the group's product rows in the DB by normalized-name matching
- *   2. Creates ONE new product_info row (clean name = md section header)
- *   3. Creates a new product_skus row per old product, copying images + features
- *      (plus any group-specific extra features) and product_market_stats
- *   4. Re-points every reference to the old SKUs / old products:
- *        product_tags.product_id, product_group_membership.product_id,
- *        order_items.sku_id, cart_items.sku_id, special_deals.sku_id,
- *        coupon_applicable_products.sku_id, product_combos.sku_id & combo_sku_id,
- *        product_reviews.product_id, and the JSON `sku_ids` arrays in
- *        home_banners, delivery_slot_info, vendor_snippets, coupons, reserved_coupons
- *   5. Deletes the old product_market_stats, sku_features, product_skus and
- *      product_info rows
- *
- * Call it whenever you wish:
- *
- *   import { mergeDuplicateProducts } from '@packages/db_helper_sqlite'
- *   const report = await mergeDuplicateProducts()
- *
- * You can also pass the md content explicitly (e.g. read from disk in a script):
- *
- *   const md = await Bun.file('docs/duplicate-products-local_8_aug.md').text()
- *   const report = await mergeDuplicateProducts(md)
- *
- * It is safe to call repeatedly: groups whose rows no longer exist (e.g. from
- * a previous run) are skipped and reported in `report.skippedGroups` instead
- * of throwing. It only throws on genuinely anomalous data (a matched product
- * with more than one SKU) or if any leftover reference to old ids survives.
