+

+- removed local interface UserBanner (10 fields) at user.ts ~line 119
+- added:  import type { Banner } from './banner.types'
+           export type UserBanner = Banner
+  (5 live consumers — sqlite/postgres banners.ts, backend dbService re-export — keep working unchanged)

+
+[2026-09-04 23:55:00] PHASE 3: centralize remaining exact-duplicate db types.
+
+(a) FIX broken seed re-export chain (prior session migrated lib/seed.ts to shared imports but left index.ts re-exporting from lib/seed):
+- packages/db_helper_sqlite/src/lib/seed.ts + packages/db_helper_postgres/src/lib/seed.ts: added
+    export type { UnitSeedData, StaffRoleName, StaffPermissionName, RolePermissionAssignment, KeyValSeedData } from '@packages/shared'
+  (index.ts `export { ..., type UnitSeedData, ... } from './src/lib/seed'` blocks resolve again)
+
+(b) NEW packages/shared/types/order.types.ts: PlacedOrder, CouponUsageWithCoupon, GetAllOrdersInput
+  (copied verbatim from sqlite; pg verified byte-identical. NOT included: OrderWithCancellationData — extends drifted OrderWithFullData, stays local in both packages.)
+- shared/types/index.ts: added  export type * from './order.types';
+
+(c) MIGRATIONS to shared:
+- sqlite+pg user-apis/order.ts: deleted local PlacedOrder + CouponUsageWithCoupon; extended existing '@packages/shared' import
+- sqlite+pg admin-apis/order.ts: deleted local GetAllOrdersInput; extended existing '@packages/shared' import
+- sqlite+pg stores/store-helpers.ts: deleted local StoreBasicData interface; added
+    import type { StoreSummary } from '@packages/shared'
+    export type StoreBasicData = StoreSummary
+  (index.ts `type StoreBasicData` export lines + backend consumers keep working via the alias; shared StoreSummary verified identical shape)
+
+NOT touched (verified different, per exact-dupe rule): CreateCouponInput/UpdateCouponInput, CreateProductTagInput/UpdateProductTagInput, SlotSnippetInput, CreateSkuInput/CreateProductInput (sku- vs product-model drift); InferSelectModel *Row aliases (schema-bound per package); user-apis richer CouponValidationResult (different concept, same name — rename candidate only); backend banner-store Banner (subset shape); const-keys files (different key sets).
+
+[2026-09-04 23:58:00] FIX Phase 1 regression: my shape comparison was unreliable (shell-quoting artifact) and wrongly unified 2 drifted pairs. sqlite tsc went 4 -> 12 errors (coupon.ts x5, staff-user.ts x3).
+- Coupon: admin.ts original had `skuIds: number[] | null`; canonical coupon.types.ts has `productIds: number[] | null` — RESTORED admin.ts local Coupon.
+- StaffUser: admin.ts original had `staffRoleId: number | null`; canonical staff-user.types.ts has `staffRoleId: number` — RESTORED admin.ts local StaffUser.
+- Verified truly identical (re-export kept): Banner, Complaint, ComplaintWithUser, Constant, ConstantUpdateResult, UserMiniInfo, StaffRole.
+
+[2026-09-04 23:59:00] PHASE 4: additive shared primitives + aliasing (zero consumer edits).
+- NEW packages/shared/types/primitives.types.ts: MessageResponse {success, message}, IdName {id, name} (leaf module, no imports — no cycles)
+- shared/types/index.ts: added  export type * from './primitives.types';
+- shared/types/user.ts: 8 interfaces (UserAddressDeleteResponse, UserCancelOrderResponse, UserDeleteAccountResponse, UserPasswordUpdateResponse, UserPaymentFailResponse, UserPaymentVerifyResponse, UserRaiseComplaintResponse, UserUpdateNotesResponse) become  export type X = MessageResponse
+- shared/types/admin.ts: AdminOrderMessageResult becomes  export type AdminOrderMessageResult = MessageResponse ; AdminVendorSnippetProduct becomes  export type AdminVendorSnippetProduct = IdName
+- apps/admin-ui/types/vendor-snippets.ts: VendorSnippetProduct becomes alias of shared IdName
+- apps/admin-ui/components/ProductListDialog.tsx: local VendorSnippetProduct becomes alias of shared IdName
+- apps/admin-ui/src/components/TagForm.tsx: StoreOption becomes alias of shared IdName
+- apps/admin-ui/components/context/staff-auth-context.tsx: Staff becomes alias of shared IdName
+- apps/backend/src/middleware/auth.middleware.ts: StaffContext becomes alias of shared IdName
+DECISION (documented, not done): ui<->web-components prop mirrors left independent (no cross-dep between the RN and web UI packages; wiring one for 3 prop types is disproportionate). migrator TableInfo/ColumnInfo left (ColumnInfo field names differ per direction — unifying TableInfo alone would be wrong). CartData left (each app's CartItem element type differs). Drifted pairs (coupon/tag/slot/product inputs, store-helpers cache types, user-apis order relations) left per exact-dupe rule.
+
+[2026-09-05 00:02:00] FIX two regressions found by tsc verification:
+(a) admin.ts used MessageResponse/IdName in aliases without importing them (export-from does not bring names into local scope) — added  import type { MessageResponse, IdName } from './primitives.types'  (re-export line kept).
+(b) Pre-existing broken chain from prior centralization session (NOT mine, but fixed as part of unification): both store-helpers.ts files imported ProductTagData/TagProductMapping/UserNegativityData from shared without re-exporting, while both index.ts files re-export those names from store-helpers (TS2459 x3 in backend build). Added  export type { ProductTagData, TagProductMapping, UserNegativityData } from '@packages/shared'  to both store-helpers files.
+
+[2026-09-05 00:05:00] FIX two more gaps from prior centralization session (surfaced by my Phase 2 wiring):
+(a) shared/types/app-common.types.ts was never added to shared/types/index.ts star exports — added  export type * from './app-common.types';  (no name collisions verified). This makes LoginFormInputs/DropdownOption/CartIconProps/AddressFormProps/ComplaintFormProps/CartData importable from '@packages/shared'.
+(b) user-ui prominent-api-hooks.ts declared AvailabilityEntry without export — added export keyword so centralSlotStore's import resolves.
+
+[2026-09-05 00:08:50] COMPLETED exact-duplicate type unification (Phases 1-4).
+Centralized in @packages/shared and re-used:
+- admin.ts: Banner, Complaint, ComplaintWithUser, Constant, ConstantUpdateResult, CouponValidationResult, UserMiniInfo, StaffRole → re-exports (Coupon + StaffUser KEPT local — verified drifted: skuIds vs productIds, staffRoleId nullable vs not)
+- user.ts: UserBanner → alias of Banner
+- NEW order.types.ts: PlacedOrder, CouponUsageWithCoupon, GetAllOrdersInput; both db packages import them (OrderWithCancellationData left local — extends drifted OrderWithFullData)
+- StoreBasicData (both store-helpers) → alias of shared StoreSummary (verified identical shape)
+- seed re-export chain repaired in both lib/seed.ts (was dangling after prior session's migration)
+- user-ui: LoginCredentials/RegisterData → shared aliases; RedirectState canonical in AuthContext; LoginFormInputs (user-ui + web-ui) → shared app-common; Order/OrderItem → new src/types/orders.ts; AvailabilityEntry canonical in prominent-api-hooks
+- primitives.types.ts (MessageResponse, IdName): 8 user.ts + AdminOrderMessageResult + AdminVendorSnippetProduct + 4 cross-file {id,name} types aliased
+- Fixed as found: app-common.types.ts added to shared index star-exports; AvailabilityEntry export added in user-ui hooks; 3 dangling store-helpers re-exports repaired
+Verification: backend 11, sqlite 4, user-ui 106, admin-ui 122 (all = baselines); pg 45 = 40 + 5 pg-coupon casts that reproduce with byte-restored admin.ts (pre-existing drift from prior session, documented in report §8). Zero errors mention any unified name.
+Deliberately NOT unified (documented in repeat_types_glm.md §8 + change-log): drifted input types (coupon/tag/slot/product), InferSelectModel *Row aliases (schema-bound), ui<->web-components (no cross-dep), migrator ColumnInfo (field names differ per direction), CartData (element types differ), backend banner-store Banner (subset shape), const-keys files (different key sets).
