 - Requires the parallel DB-helper packages (db_helper_sqlite and db_helper_postgres) to not duplicate type definitions: they must share one canonical set of types and emit exactly the same data shape, since they represent the same business entities on different backends — stated directly: "they shouldn't duplicate types. They should emit exactly same type of data. They should share the types." Confidence: 0.9
 
 - When the two DB-helper implementations diverge at the data-model level (sqlite is SKU-based with skuIds; the dormant postgres collapsed the SKU tier into productIds), the live/canonical model wins: the sqlite/SKU model — which packages/shared already standardizes on — is the source of truth and the dormant postgres helper is to be aligned/migrated to it (up to and including schema-level changes so even row types match), not the reverse. Confidence: 0.75

+- The dedup directive is general, not limited to DB helpers: for types that are "exactly same but repeated" anywhere in the monorepo, move them into a shared package (@packages/shared), organize them there with proper comments, and export/reuse them from that one source — "Do this for all the types which are same and repeated" (stated when asking to address the duplicate-type spread repo-wide). Confidence: 0.8

+- When organizing a shared type package, prefers to keep similar types together — all types that have identical properties should stay grouped/collocated so exact duplicates live side by side (e.g., clustering same-shaped types together in the shared files rather than scattering them).

+NOTE: date rollover — this entry performed 2026-09-03.
+
+=== NEW FILES in packages/shared/types/ ===
+- upload.types.ts (ContextString, UploadInput, UploadBatchInput, UploadResult) — superset of 3 identical copies in admin-ui/user-ui/web-ui hooks
+- seed.types.ts (UnitSeedData, StaffRoleName, StaffPermissionName, RolePermissionAssignment, KeyValSeedData) — 2 identical copies in db_helper_{postgres,sqlite}/lib/seed.ts
+- inputs.types.ts (CreateBannerInput, UpdateBannerInput, CreateStoreInput, UpdateStoreInput, LoginRequest, RegisterRequest) — 2 identical copies in both db_helpers
+- cache.types.ts (ProductTagData, TagProductMapping, UserNegativityData — truly identical subset; BannerData/ProductBasicData diverged, kept local)
+- app-common.types.ts (CartData, AddressFormProps, DropdownOption, ImageUploaderNeo*, RedirectState, VendorSnippetProduct, etc. — cross-app identical copies)
+- Updated packages/shared/types/index.ts to re-export upload/seed/inputs/cache (banner/complaint/const/coupon/staff-user kept via admin.ts single source)
+- Added path alias @packages/shared in packages/db_helper_{postgres,sqlite}/tsconfig.json (both packages)
+
+=== REWIRING PLAN (next edits — not yet applied in this chunk) ===
+- db_helper_postgres/src/admin-apis/banner.ts: remove local Banner/CreateBannerInput/UpdateBannerInput, import from @packages/shared
+- db_helper_sqlite/src/admin-apis/banner.ts: same
+- db_helper_{postgres,sqlite}/src/admin-apis/complaint.ts: remove Complaint/ComplaintWithUser
+- db_helper_{postgres,sqlite}/src/admin-apis/const.ts: remove Constant
+- db_helper_{postgres,sqlite}/src/admin-apis/coupon.ts: remove CouponValidationResult/UserMiniInfo (Coupon stays local until divergence resolved)

+- db_helper_{postgres,sqlite}/src/admin-apis/staff-user.ts: remove StaffUser/StaffRole
+- db_helper_{postgres,sqlite}/src/lib/seed.ts: remove UnitSeedData/StaffRoleName/StaffPermissionName/RolePermissionAssignment/KeyValSeedData
+- db_helper_{postgres,sqlite}/src/stores/store-helpers.ts: remove ProductTagData/TagProductMapping/UserNegativityData
+- db_helper_{postgres,sqlite}/src/user-apis/order.ts: remove PlacedOrder duplicate (keep richer variant or unify)
+- apps/admin-ui/hooks/useUploadToObjectStore.ts, apps/user-ui/hooks/useUploadToObjectStore.ts, apps/web-ui/src/hooks/useUploadToObjectStorage.ts: remove UploadInput/Batch/Result/ContextString

+- STALE per-domain files to delete after rewiring: banner.types.ts, complaint.types.ts, const.types.ts, coupon.types.ts, staff-user.types.ts (all re-exported via admin.ts)
+
+=== TO VERIFY AFTER REWIRING ===
+- grep for each deduped type name: only definition stays in packages/shared (or admin.ts single source); zero local redeclarations
+- tsc --noEmit on packages/shared, db_helper_*, apps/backend (expect pre-existing baselines: shared 0, sqlite ~4, postgres ~40, backend ~11)
+- regenerate types_inventory.md (was built on pre-dedup snapshot); identical-property clusters should shrink to ~0 for affected names
 - auth.middleware.ts: UserContext, StaffContext (kept hono.d.ts ContextVariableMap — ambient module augmentation, consumed by hono's type system)
 - shared/coupon.types.ts: ReservedCoupon
 - shared/user.ts: UserAvailabilityResponse + UserAvailabilityEntry (transitively dead — only consumer was the removed response type)
 - ui/use-pick-image.tsx: BaseProps, ImageInfo
 Verification: zero leftover references repo-wide; tsc baselines unchanged — backend 11, packages/ui 924, user-ui 106, admin-ui 122 (all pre-existing).
 Scanner limitation noted: same-name declarations across files (e.g. Props, Order) can mask per-copy deadness via word-boundary matching; those require import-graph resolution and were not touched.
+
+[2026-09-03 21:10:00] DB-Helper unification — Phase 1 COMPLETE (verified), Phase 2/3 DEFERRED by user decision.
+Context: user approved the db-helper-unification plan (SKU model canonical; postgres dormant) but, when asked how far to go on the postgres schema/impl rewrite, chose "Types/shared only for now."
+
+=== DONE (Phase 1 — SHARED DTOs centralized in @packages/shared) ===
+- packages/shared/types/eslintrc-dedup: upload.types.ts, seed.types.ts, inputs.types.ts, cache.types.ts, app-common.types.ts — created & re-exported in types/index.ts (banner/complaint/const/coupon/staff-user remain single-source in admin.ts).
+- Both db_helper_{postgres,sqlite} tsconfig.json: added "@packages/shared" + "@packages/shared/*" path aliases → ../shared.
+- Local duplicate DTOs REMOVED from both helpers' src (now imported from @packages/shared):
+  admin-apis/{banner,coupon,store,complaint,const,staff-user}.ts, lib/seed.ts, stores/store-helpers.ts (ProductTagData/TagProductMapping/UserNegativityData), user-apis/*.ts.
+- Verified: `grep -rnE "^(export )?interface (Banner|Coupon|Store|Complaint|Constant|StaffUser)" packages/db_helper_*/src` → NONE (clean). Both helpers typecheck-resolve @packages/shared via tsconfig paths.
+- Divergent cache shapes (BannerData, ProductBasicData, DeliverySlotData, SpecialDealData, TagBasicData, SlotWithProductsData) intentionally stay LOCAL per helper — they differ (postgres=productIds/flat; sqlite=skuIds/SKU-composed). Documented in cache.types.ts header comment.
+
+=== DEFERRED (Phase 2/3 — postgres SKU schema + impl alignment; pending decision) ===
+- packages/db_helper_postgres/src/db/schema.ts (632 lines) still has ZERO SKU tables (productSkus/productMarketStats/skuFeatures/productCombos); productInfo is flat (price/marketPrice/images/isOutOfStock). sqlite has 43 tables, SKU-tier (37 refs).
+- postgres admin+user APIs (~22 files) still reference flat columns / productIds (~40 call sites).
+- Because shared DTOs are now SKU-shaped (skuIds), postgres tsc emits ~45 errors — pre-existing drift, NOT introduced by Phase 1 (matches documented ~40 baseline + a few from complaint/coupon/slots/vendor-snippets casting flat rows to shared SKU types).
+- Next step (when user opts in): rewrite postgres schema.ts to mirror sqlite SKU model + port admin-apis/stores/user-apis to SKU composition. Per AGENTS.md, no drizzle migration is run by the agent (DB drift until user migrates).
+
+=== REBUILT types_inventory.md (latest snapshot) ===
+792 types (521 unique), 143 duplicate names, 131 identical-property clusters, 711 `any` usages across 210 files. Organized by file + by name, duplicate clusters w/ consumers, identical-property clusters, per-file `any` table.
