(no file changes made yet in this session) [2026-09-02 20:34:48] DELETE dead files per DEAD_CODE_REPORT.md §1 (28 files): Removed in packages/db_helper_sqlite/src/helper_methods/: - banner.ts (entire file — legacy duplicate, never imported) - complaint.ts (entire file — legacy duplicate, never imported) - const.ts (entire file — legacy duplicate, never imported) - coupon.ts (entire file — legacy duplicate, never imported) - order.ts (entire file — legacy duplicate, never imported) - product.ts (entire file — legacy duplicate, never imported) - slots.ts (entire file — legacy duplicate, never imported) - staff-user.ts (entire file — legacy duplicate, never imported) - store.ts (entire file — legacy duplicate, never imported) - user.ts (entire file — legacy duplicate, never imported) - vendor-snippets.ts (entire file — legacy duplicate, never imported) Removed in packages/db_helper_postgres/src/helper_methods/: (same 11 files as above) - banner.ts, complaint.ts, const.ts, coupon.ts, order.ts, product.ts, slots.ts, staff-user.ts, store.ts, user.ts, vendor-snippets.ts (entire files — legacy duplicates, never imported) Removed in both packages (db_helper_sqlite + db_helper_postgres): - src/user-apis/tags.ts (entire file — imported by no one) - src/common-apis/utils.ts (entire file — imported by no one; formatDate/generateCode/calculateDiscount unreferenced) - src/db/types.ts (entire file — imported by no one) Kept: helper_methods/upload-url.ts (alive — re-exported by index.ts, used by backend). Command: rm [2026-09-02 20:38:02] COMPLETED deletion of 28 dead files (DEAD_CODE_REPORT.md §1). Verification: - grep for 'helper_methods|user-apis/tags|common-apis/utils|db/types' across both packages + apps/backend: only remaining match is the live import of helper_methods/upload-url.ts in both index.ts files. - tsc --noEmit on both packages reports pre-existing errors only (in untouched live files: src/db/seed.ts, src/user-apis/order.ts, src/user-apis/product.ts, src/admin-apis/complaint.ts, src/admin-apis/product.ts). No errors reference any deleted module. [2026-09-02 20:45:45] DELETE dead exported methods per DEAD_CODE_REPORT.md §2a (8 symbols, both packages). === packages/db_helper_sqlite/src/admin-apis/product.ts === - removed getAllUnits (lines 650-657): export async function getAllUnits(): Promise { const allUnits = await db.query.units.findMany({ orderBy: units.shortNotation, }) return allUnits.map(mapUnit) } - removed addProductToGroup (lines 1032-1034): export async function addProductToGroup(groupId: number, productId: number): Promise { await db.insert(productGroupMembership).values({ groupId, productId }) } - removed removeProductFromGroup (lines 1036-1042): export async function removeProductFromGroup(groupId: number, productId: number): Promise { await db.delete(productGroupMembership) .where(and( eq(productGroupMembership.groupId, groupId), eq(productGroupMembership.productId, productId) )) } === packages/db_helper_postgres/src/admin-apis/product.ts === - identical removals (getAllUnits at 232-239, addProductToGroup at 496-498, removeProductFromGroup at 500-506) === packages/db_helper_sqlite/src/admin-apis/vendor-snippets.ts === - removed getOrderItemsByOrderIds (lines 196-209): export async function getOrderItemsByOrderIds(orderIds: number[]) { return await db.query.orderItems.findMany({ where: inArray(orderItems.orderId, orderIds), with: { sku: { with: { product: true, features: true } } }, }) } - removed getOrderStatusByOrderIds (lines 210-214): export async function getOrderStatusByOrderIds(orderIds: number[]) { return await db.query.orderStatus.findMany({ where: inArray(orderStatus.orderId, orderIds), }) } === packages/db_helper_postgres/src/admin-apis/vendor-snippets.ts === - removed getOrderItemsByOrderIds (lines 188-200) — same signature; body joins product.unit instead of sku: export async function getOrderItemsByOrderIds(orderIds: number[]) { return await db.query.orderItems.findMany({ where: inArray(orderItems.orderId, orderIds), with: { product: { with: { unit: true } } }, }) } - removed getOrderStatusByOrderIds (lines 201-205) — identical to sqlite === packages/db_helper_sqlite/src/admin-apis/staff-user.ts + packages/db_helper_postgres/src/admin-apis/staff-user.ts === - removed updateUserSuspensionStatus (lines 101-109 in both) — duplicate of live upsertUserSuspension: export async function updateUserSuspensionStatus(userId: number, isSuspended: boolean): Promise { await db .insert(userDetails) .values({ userId, isSuspended }) .onConflictDoUpdate({ target: userDetails.userId, set: { isSuspended }, }) } === packages/db_helper_sqlite/src/user-apis/user.ts + packages/db_helper_postgres/src/user-apis/user.ts === - removed getUserWithCreds (lines 15-28 in both): export async function getUserWithCreds(userId: number) { const result = await db .select() .from(users) .leftJoin(userCreds, eq(users.id, userCreds.userId)) .where(eq(users.id, userId)) .limit(1) if (result.length === 0) return null return { user: result[0].users, creds: result[0].user_creds } } === packages/db_helper_sqlite/src/user-apis/auth.ts + packages/db_helper_postgres/src/user-apis/auth.ts === - removed createUserWithCreds (lines 145-168 in both): export async function createUserWithCreds(input: { name; email; mobile; hashedPassword }) { return db.transaction(async (tx) => { ...insert user, insert userCreds, return user... }) } === packages/db_helper_sqlite/index.ts (export list cleanup) === - removed line: getAllUnits, - removed lines: addProductToGroup, removeProductFromGroup, - removed lines: getOrderItemsByOrderIds, getOrderStatusByOrderIds, - removed line: updateUserSuspensionStatus, - removed line: getUserWithCreds as getUserWithCreds, - removed line: createUserWithCreds as createUserAuthWithCreds, === packages/db_helper_postgres/index.ts (export list cleanup) === - same 8 export-line removals as sqlite index.ts === apps/backend/src/sqliteImporter.ts (re-export chain cleanup) === - removed line: getAllUnits, - removed lines: addProductToGroup, removeProductFromGroup, - removed lines: getOrderItemsByOrderIds, getOrderStatusByOrderIds, - removed line: updateUserSuspensionStatus, - removed line: createUserAuthWithCreds, - removed line: getUserWithCreds, Note: apps/backend/src/dbService.ts uses `export * from '@/src/sqliteImporter'` — no per-symbol change needed there. Any imports left unused by these deletions (e.g. productGroupMembership, inArray, userCreds) will be removed in a follow-up entry if tsc/grep confirms they are unused. [2026-09-02 20:49:23] FOLLOW-UP: remove imports/orphans left unused by §2a deletions. === packages/db_helper_sqlite/src/admin-apis/product.ts === - removed now-unused local type + mapper (only consumer was deleted getAllUnits): line 103: type UnitRow = InferSelectModel line 117: const mapUnit = (unit: UnitRow): AdminUnit => ({ id: unit.id, shortNotation: unit.shortNotation, fullName: unit.fullName, }) (postgres product.ts keeps mapUnit — still used there at lines 111, 142) === packages/db_helper_sqlite/src/user-apis/user.ts === - import line 2: removed 'userCreds' from import { notifCreds, unloggedUserTokens, userCreds, userDetails, users } from '../db/schema' === packages/db_helper_postgres/src/user-apis/user.ts === - same import fix as sqlite user.ts [2026-09-02 20:51:30] COMPLETED §2a deletion (8 dead exported methods, both packages + re-export chains). Removed: getAllUnits, addProductToGroup, removeProductFromGroup, getOrderItemsByOrderIds, getOrderStatusByOrderIds, updateUserSuspensionStatus, getUserWithCreds, createUserWithCreds (+ orphaned mapUnit/UnitRow in sqlite product.ts, orphaned userCreds imports in both user.ts). Verification: - grep across packages + apps: zero live references remain (only commented lines in postgresImporter.ts). - tsc --noEmit: sqlite = 4 errors (same as pre-change baseline), postgres = 40 errors (all pre-existing drizzle inference mismatches in untouched files), backend = 17 errors (all pre-existing, in untouched files). No error references any deleted symbol. [2026-09-02 20:54:32] DELETE §2b/§2c dead exports + PARITY RENAME + RESTORE two methods for future use. --- DELETIONS, packages/db_helper_sqlite/src/admin-apis/product.ts --- - removed createSpecialDealsForSku (lines 1124-1145): inserts specialDeals rows keyed by skuId, returns mapped AdminSpecialDeal[] - removed updateSkuDeals (lines 1147-1241): diff-based sync of specialDeals for a skuId (add/remove/update validTill) - removed mergeSkus (lines 1243-1366, end of file): merges fromSkuId into toSkuId across orderItems, specialDeals, cartItems, couponApplicableProducts, JSON skuIds columns (deliverySlotInfo, homeBanners, coupons, reservedCoupons, vendorSnippets), keyValStore popularItems, then deletes skuFeatures + sku + orphaned product --- DELETIONS, packages/db_helper_postgres/src/admin-apis/product.ts --- - removed toggleProductOutOfStock (lines 181-203): flips productInfo.isOutOfStock - removed createSpecialDealsForProduct (lines 677-698): postgres counterpart of createSpecialDealsForSku (keyed by productId) - removed updateProductDeals (lines 700-775): postgres counterpart of updateSkuDeals --- DELETION, packages/db_helper_postgres/src/lib/automated-jobs.ts --- - removed toggleFlashDeliveryForItems (lines 10-16): bulk productInfo.isFlashAvailable update - import line 2: removed 'productInfo' from import { productInfo, keyValStore } from '../db/schema' - import line 3: removed 'inArray' from import { inArray, eq } from 'drizzle-orm' --- EXPORT LIST, packages/db_helper_sqlite/index.ts --- - removed lines: createSpecialDealsForSku, updateSkuDeals, mergeSkus, --- EXPORT LIST, packages/db_helper_postgres/index.ts --- - removed lines: createSpecialDealsForProduct, updateProductDeals, toggleProductOutOfStock, - removed line: toggleFlashDeliveryForItems, --- EXPORT LIST, apps/backend/src/sqliteImporter.ts --- - removed lines: createSpecialDealsForSku, updateSkuDeals, mergeSkus, --- PARITY RENAME, packages/db_helper_postgres/src/user-apis/product.ts --- - renamed getSuspendedProductIds -> getSuspendedSkuIds (backend calls getSuspendedSkuIds; sqlite exports that name). NOTE: implementation unchanged (queries productInfo.isSuspended) — postgres schema has no sku/marketStats model, so this is the closest postgres equivalent of the sqlite query on productMarketStats.skuId. - packages/db_helper_postgres/index.ts: export line getSuspendedProductIds, -> getSuspendedSkuIds, --- RESTORE (user request: needed in future), both packages --- packages/db_helper_sqlite/src/user-apis/user.ts + packages/db_helper_postgres/src/user-apis/user.ts: - re-added getUserWithCreds: export async function getUserWithCreds(userId: number) { const result = await db .select() .from(users) .leftJoin(userCreds, eq(users.id, userCreds.userId)) .where(eq(users.id, userId)) .limit(1) if (result.length === 0) return null return { user: result[0].users, creds: result[0].user_creds, } } - re-added 'userCreds' to the schema import line in both files. packages/db_helper_sqlite/src/user-apis/auth.ts + packages/db_helper_postgres/src/user-apis/auth.ts: - re-added createUserWithCreds: export async function createUserWithCreds(input: { name: string email: string mobile: string hashedPassword: string }) { return db.transaction(async (tx) => { const [user] = await tx.insert(users).values({ name: input.name, email: input.email, mobile: input.mobile, }).returning() await tx.insert(userCreds).values({ userId: user.id, userPassword: input.hashedPassword, }) return user }) } packages/db_helper_sqlite/index.ts + packages/db_helper_postgres/index.ts: - re-added export lines: createUserWithCreds as createUserAuthWithCreds, (user auth block) getUserWithCreds as getUserWithCreds, (user profile block) apps/backend/src/sqliteImporter.ts: - re-added re-export lines: createUserAuthWithCreds, and getUserWithCreds, [2026-09-02 20:58:19] FOLLOW-UP: remove orphaned CreateSpecialDealInput (only consumers were the deleted deal functions; zero usages repo-wide). === packages/db_helper_sqlite/src/admin-apis/product.ts === - removed (line ~1118): export interface CreateSpecialDealInput { quantity: number price: number validTill: string | Date } === packages/db_helper_postgres/src/admin-apis/product.ts === - removed identical interface (line ~647) [2026-09-02 20:59:28] COMPLETED §2b/§2c deletions + parity rename + restoration of createUserWithCreds/getUserWithCreds. Verification: - grep: zero references to createSpecialDealsForSku, updateSkuDeals, mergeSkus, createSpecialDealsForProduct, updateProductDeals, toggleProductOutOfStock, toggleFlashDeliveryForItems, getSuspendedProductIds (only commented postgresImporter.ts lines excluded from check). - Restored methods present in both packages' src + index.ts + backend sqliteImporter.ts. - Postgres now exports getSuspendedSkuIds (renamed from getSuspendedProductIds) matching sqlite/backend usage. - tsc --noEmit baselines unchanged: sqlite 4, postgres 40, backend 17 errors — all pre-existing, none reference touched symbols. [2026-09-02 21:01:52] §3 EXPORT-ONLY DEAD cleanup: remove from index.ts (implementations kept), delete non-exported dead types. === packages/db_helper_sqlite/index.ts === - removed line 10 block: export { staffRoleEnum, staffPermissionEnum } from './src/db/schema' (these enum values still flow to consumers via the existing `export * from './src/db/schema'` — the explicit line was redundant) - user product block: removed type lines type SkuSummary, type OffersPageData, type OffersPageProductData, - store helpers block: removed line type AvailabilityCacheData, - user order block: removed type lines type OrderWithFullData, type OrderWithCancellationData, - SKU Features block: removed lines cleanFeatureValue, splitQuantityFeature, type SkuFeatureLike, (kept composeUnitNotation, composeSkuName — used by backend) === packages/db_helper_postgres/index.ts === - removed line 11 block: export { staffRoleEnum, staffPermissionEnum } from './src/db/schema'; - user order block: removed type lines type OrderWithFullData, type OrderWithCancellationData, === apps/backend/src/sqliteImporter.ts === - removed type lines type OrderWithFullData, type OrderWithCancellationData, - removed line getUserNotifCred, Note: getNotifCred index export line in both packages: getNotifCred as getUserNotifCred, — removed (see below). === packages/db_helper_sqlite/index.ts + packages/db_helper_postgres/index.ts === - user profile block: removed line getNotifCred as getUserNotifCred, (function getNotifCred kept in user.ts — called internally by upsertNotifCred) === packages/db_helper_sqlite/src/user-apis/order.ts === - removed dead interface (lines 33-40): export interface PlaceOrderInput { userId: number selectedItems: OrderItemInput[] addressId: number paymentMethod: 'online' | 'cod' couponId?: number userNotes?: string isFlash?: boolean } - removed dead interface (lines 43-51): export interface OrderGroupData { slotId: number | null items: Array<{ productId: number quantity: number slotId: number | null product: typeof productInfo.$inferSelect }> } === packages/db_helper_postgres/src/user-apis/order.ts === - removed identical PlaceOrderInput (lines 29-36) and OrderGroupData (lines 39-47) [2026-09-02 21:04:10] CORRECTION to previous entry: while editing packages/db_helper_sqlite/index.ts user product block I accidentally removed getAllSkusSummary, getOffersAndCombos and type ProductSummaryData (all three are USED by backend). Immediately restored them; final state of that block keeps: getAllProductsWithUnits, getAllSkusSummary, getOffersAndCombos, type ProductSummaryData. Only type SkuSummary, type OffersPageData, type OffersPageProductData were meant to be (and now are) removed. [2026-09-02 21:07:40] CORRECTION: while editing the user order block of packages/db_helper_sqlite/index.ts I accidentally removed getOrdersByIdsWithFullData and getOrderByIdWithFullData (both USED by backend post-order-handler). Immediately restored. Final state: those two functions kept; only type OrderWithFullData and type OrderWithCancellationData removed from that block. Also fixed an earlier accidental newline removal after the store-helpers export close brace. [2026-09-02 21:05:24] FOLLOW-UP: remove orphaned OrderItemInput from user-apis/order.ts in both packages (its only consumer, PlaceOrderInput, was deleted; definition-only now). === packages/db_helper_sqlite/src/user-apis/order.ts === - removed (lines 27-31): export interface OrderItemInput { productId: number quantity: number slotId: number | null } === packages/db_helper_postgres/src/user-apis/order.ts === - removed identical interface (lines 23-27) [2026-09-02 21:06:16] COMPLETED §3 export-only-dead cleanup. Removed from index.ts (implementations kept in src): - both packages: redundant staffRoleEnum/staffPermissionEnum export block (still exported via `export * from './src/db/schema'`), type OrderWithFullData, type OrderWithCancellationData, getNotifCred as getUserNotifCred - sqlite only: type SkuSummary, type OffersPageData, type OffersPageProductData, type AvailabilityCacheData, cleanFeatureValue, splitQuantityFeature, type SkuFeatureLike (kept composeUnitNotation/composeSkuName) Removed from apps/backend/src/sqliteImporter.ts: type OrderWithFullData, type OrderWithCancellationData, getUserNotifCred Deleted dead types in user-apis/order.ts (both packages): PlaceOrderInput, OrderGroupData, OrderItemInput Verification: - Backend-used exports confirmed intact: getAllSkusSummary, getOffersAndCombos, ProductSummaryData, getOrdersByIdsWithFullData, getOrderByIdWithFullData, getAvailabilityForCache, getAllProductCombosForCache, getUserWithCreds, createUserAuthWithCreds, composeSkuName, composeUnitNotation - tsc --noEmit baselines unchanged: sqlite 4 (seed.ts 1, order.ts 2, product.ts 1), postgres 40, backend 17 — all pre-existing, none reference touched symbols. [2026-09-02 21:21:13] §4: remove never-referenced schema tables — addressZones, addressAreas, userNotifications, productCategories (BOTH packages). NOTE: this only removes them from the drizzle schema (code). The actual DB tables/columns/FK constraints still exist in D1/Postgres — dropping them in the DB requires a migration, which the user will handle (per AGENTS.md). Both schema.ts files drift from the live DB until then; drizzle-kit push/generate must NOT be run by the agent. === packages/db_helper_sqlite/src/db/schema.ts === - removed addressZones table (lines 106-110): export const addressZones = sqliteTable('address_zones', { id: integer().primaryKey({ autoIncrement: true }), zoneName: text('zone_name').notNull(), addedAt: timestampText('added_at').notNull().default(sql`CURRENT_TIMESTAMP`), }) - removed addressAreas table (lines 112-117): export const addressAreas = sqliteTable('address_areas', { id: integer().primaryKey({ autoIncrement: true }), placeName: text('place_name').notNull(), zoneId: integer('zone_id').references(() => addressZones.id), createdAt: timestampText('created_at').notNull().default(sql`CURRENT_TIMESTAMP`), }) - addresses table: changed zoneId column to drop FK (column KEPT — shared UserAddress type and user-apis/address.ts mapUserAddress still expose zoneId): before: zoneId: integer('zone_id').references(() => addressZones.id), after: zoneId: integer('zone_id'), - removed productCategories table (lines 431-434): export const productCategories = sqliteTable('product_categories', { id: integer().primaryKey({ autoIncrement: true }), name: text().notNull(), description: text(), }) - removed userNotifications table (lines 545-551): export const userNotifications = sqliteTable('user_notifications', { id: integer().primaryKey({ autoIncrement: true }), title: text('title').notNull(), imageUrl: text('image_url'), createdAt: timestampText('created_at').notNull().default(sql`CURRENT_TIMESTAMP`), body: text('body').notNull(), applicableUsers: jsonText('applicable_users'), }) - addressesRelations: removed line zone: one(addressZones, { fields: [addresses.zoneId], references: [addressZones.id] }), - removed productCategoriesRelations (line 686): export const productCategoriesRelations = relations(productCategories, ({}) => ({})) - removed userNotificationsRelations (lines 720-722): export const userNotificationsRelations = relations(userNotifications, ({}) => ({ // No relations needed for now })) - removed addressZonesRelations (lines 749-752): export const addressZonesRelations = relations(addressZones, ({ many }) => ({ addresses: many(addresses), areas: many(addressAreas), })) - removed addressAreasRelations (lines 754-756): export const addressAreasRelations = relations(addressAreas, ({ one }) => ({ zone: one(addressZones, { fields: [addressAreas.zoneId], references: [addressZones.id] }), })) === packages/db_helper_postgres/src/db/schema.ts === (same removals, postgres style) - removed addressZones table (lines 58-62, mf.table('address_zones', ...)) - removed addressAreas table (lines 64-69, mf.table('address_areas', ...)) - addresses.zoneId (line 54): dropped .references(() => addressZones.id) — column kept - removed productCategories table (lines 318-322, mf.table('product_categories', ...)) - removed userNotifications table (lines 434-440, mf.table('user_notifications', ...)) - addressesRelations: removed zone relation line (line 496) - removed productCategoriesRelations (line 573) - removed userNotificationsRelations (lines 607-609) - removed addressZonesRelations (lines 636-639) and addressAreasRelations (lines 641-643) [2026-09-02 21:23:14] COMPLETED §4 schema table removal. - Removed from both packages' src/db/schema.ts: addressZones, addressAreas, productCategories, userNotifications tables + productCategoriesRelations, userNotificationsRelations, addressZonesRelations, addressAreasRelations. - addresses.zoneId column KEPT (FK reference + addressesRelations.zone relation removed) because shared UserAddress type and user-apis/address.ts still expose zoneId. - Verified: zero remaining references to the 4 tables anywhere; jsonText/jsonb/text imports still used by other tables; tsc baselines unchanged (sqlite 4, postgres 40, backend 17 — all pre-existing). - REMINDER: DB tables still exist in D1/Postgres until the user runs a drop migration (agent must not run drizzle migrations). [2026-09-02 21:24:48] §6: DELETE dead backend files (10 files) + clean commented references to them. DELETED (all verified: zero live imports — only commented mentions remain): - apps/backend/src/postgresImporter.ts (entirely commented-out swap scaffold; restore from git when swapping to postgres) - apps/backend/src/lib/signed-url-cache-old.ts - apps/backend/src/lib/signed-url-cache.ts - apps/backend/src/lib/disk-persisted-set.ts (body fully commented out) - apps/backend/src/lib/catch-async.ts - apps/backend/src/lib/axios.ts (phonepeAxios never imported) - apps/backend/src/lib/delete-image.ts (deleteS3Image never imported) - apps/backend/src/lib/event-queue.ts (enqueue never imported; queue-consumer.ts is the live path) - apps/backend/src/lib/notif-service.ts - apps/backend/src/types/db.types.ts COMMENT CLEANUP (files are .ts → logged here): === apps/backend/index.ts === - removed line 5: // import signedUrlCache from '@/src/lib/signed-url-cache'; - removed line 12: // signedUrlCache.loadFromDisk(); // Disabled for Workers compatibility Left untouched: s3-client.ts:141 prose comment (mentions the concept, not an import), dbService.ts prose header.

[2026-09-02 21:25:58] COMPLETED §6 backend dead-file deletion (10 files) + index.ts comment cleanup. Verification: backend tsc --noEmit now reports 11 errors (was 17) — the 6 that vanished were signed-url-cache-old.ts's own pre-existing errors; remaining 11 are the same pre-existing set in untouched files (app.ts, lib/init.ts, s3-client.ts, main-router.ts, trpc-index.ts, sqlite order.ts/product.ts). No new errors. Note: apps/backend/src/lib/s3-client.ts.txt (a .txt copy of s3-client) still exists — left alone, flagging as possible future cleanup.
