# Frontend — PROGRESS (Phase 1: Inventory & Supply Chain) Legend: `[ ]` not started · `[~]` in progress · `[x]` done Spec: `docs/20-FRONTEND.md` (flows + rules) · `docs/11-BACKEND-PHASE1.md` (API contract) Convention: `docs/01-DOC-GUIDE.md §6`. Update this file in the **same commit** as the code. When ticking `[x]`, append a short note + any deviation. ## 0. Foundation - [x] **Transport: same-origin Next `rewrites()` proxy** (`next.config.ts`, `/api/*` → `BACKEND_ORIGIN`, default `http://localhost:5224`). `BACKEND_ORIGIN` in `.env.local` / `.env.local.example` — **not** `NEXT_PUBLIC_*`; the browser never sees the backend URL. Chosen over backend CORS because it makes the API same-origin, so CORS and the Secure/SameSite=Strict session cookies stop being problems at all. (`.gitignore`'s `.env*` was silently swallowing the example file — added a `!.env.local.example` negation.) - [x] **Typed API client rebuilt** (`lib/api-client.ts`, 2026-07-17) — recovered the pre-deletion version from git (`0e4bcf1^`) and adapted: relative `/api/v1` base, **`credentials: "include"`** (never present before), `ApiResult`/`ProblemDetails` imported from `@/types/common` rather than redeclared, `readCsrfToken()` for the eight `[ValidateCsrf]` auth actions. `ApiError`, `apiRequest`, `apiRequestWithETag`, `buildQuery`, `ifMatch`/`idempotencyKey` all carried over. - [x] **Route guard** (`proxy.ts` — Next 16's rename of `middleware.ts`; the old name still works but warns). Redirects `/dashboard/*` to `/login?next=…` when the `erp_at` cookie is absent. **Presence check only** — the cookie is httpOnly and the JWT is RS256, so the edge cannot validate it; the API stays the authority. - [x] **Auth** (`lib/api/auth.ts`, `lib/auth-session.ts`, `types/auth.ts`) — real login/logout. No token is stored: the session is httpOnly cookies. `lib/auth-session.ts` caches the user *profile* in localStorage for the Header, because there is no `GET /auth/me` and the user object only arrives in the login response. It is display data, not a credential. - [x] Shared TS types mirroring API DTOs (`types/{common,master-data,procurement,grn,stock,auth}.ts`) — **reconciled field-by-field against the live schemas 2026-07-17**; see the entry below for what had drifted. - [~] Client validation helpers (`lib/validations/grn.ts`) — **deviation**: uses `zod` (already a project dependency, used by `lib/validations.ts`/login), not hand-rolled, to stay consistent with the codebase's existing pattern rather than introduce a second validation approach. UX-only; server remains authoritative (docs/20-FRONTEND.md §3) - [x] `code → message` map (`lib/error-map.ts`) — `errorMessage`/`fieldErrors` duck-type any `{ code, detail, errors }`-shaped rejection. **Fixed 2026-07-17:** generic framework codes (`conflict`/`not_found`/`validation_error`) were shadowing the server's specific `detail`, so a duplicate brand showed "This action conflicts with the record's current state." instead of "A brand named 'bosch' already exists." Generic codes now lose to `detail`; specific domain codes still win. > **⚠️ The 2026-07-15 note below is HISTORY, not current state.** The fetch infrastructure was rebuilt on 2026-07-17 and `lib/api/mock-data.ts` is deleted — see "2026-07-17 — connected to the real API" at the bottom of this file. Its parting advice (re-verify the RFQ contract; expect to rebuild the client from scratch) was followed and proved correct. > > **2026-07-15 — fetch infrastructure deleted outright (not just reverted to mock).** Following an earlier same-week pass that wired every `lib/api/*.ts` module to real `fetch` calls (then reverted via `git revert --no-commit` at the user's request — see `Backend`-adjacent history if relevant later), the user asked to go further and delete the underlying connection mechanism entirely, not just leave it unused. Deleted `lib/api-client.ts` (`apiRequest`/`apiRequestWithETag`/`buildQuery`/`ApiError`) and `lib/auth-token.ts` (bearer-token storage) as files. Follow-on fixes this required: (1) `ApiResult` — used by `items.ts`/`purchase-orders.ts`/`vendors.ts` for their mock ETag pattern — moved into `types/common.ts`; (2) `lib/error-map.ts` rewritten to duck-type instead of `instanceof ApiError`; (3) three detail pages (`vendors/[id]`, `products/[id]`, `procurement/purchase-orders/[id]`) had their `err instanceof ApiError ? err.code : (err as {code?:string})?.code` conflict-detection simplified to the duck-typed form only. Also stripped the now-dangling commented-out "real implementation" blocks (`// import { apiRequest... } from "@/lib/api-client"` etc.) from all 15 `lib/api/*.ts` files, since they referenced a now-deleted module. `tsc --noEmit`/`eslint` clean (same pre-existing `login/page.tsx` error and established `set-state-in-effect` pattern only — confirmed unchanged by this pass). > > **If real backend integration is attempted again**, note two things found during the reverted pass: the RFQ backend contract had drifted from this file's assumed shapes (`Backend/ERPCore/Dtos/Procurement/RfqDtos.cs`/`RfqService.cs` — no persisted invited-vendor list, `requisitionId` required on create, different comparison DTO field names) — re-verify against the actual backend rather than trusting old assumptions; and a typed fetch client + ETag/error-normalization layer will need to be rebuilt from scratch since `lib/api-client.ts`/`lib/auth-token.ts` no longer exist. ## 1. Auth - [x] Login screen — **wired 2026-07-17** to `POST /auth/login`. Previously it `console.log`'d the plaintext password and pushed to `/dashboard` unconditionally; any schema-valid input "logged in". Now: real call, session cookies, server errors surfaced, `?next=` honoured (same-origin paths only — an absolute URL there would be an open redirect). - [x] Route guard (`proxy.ts`) + real logout in `components/Layouts/Header.tsx` — the Header no longer hardcodes `john52martinez@gmail.com`, and "Log out" is a real `POST /auth/logout` rather than a ``. - [~] Forgot password — add email screen — UI built (`app/login/forgot`); not yet wired to API - [~] Forgot password — verify OTP screen — UI built (`app/login/forgot/otp`); not yet wired to API - [~] Forgot password — change password screen — UI built (`app/login/forgot/reset`); not yet wired to API ## 2. Master Data screens - [~] Items (`app/dashboard/products` list + filters, `/new` create, `/[id]` full edit + ETag/If-Match with 412-conflict handling + activate/deactivate) — FR-MD-01/08. **2026-07-22:** `/new` gained a **"Fixed price / Use stock value" sale-price toggle** — see the 2026-07-22 entry. Reused the pre-existing "Products" sidebar entry/stub route rather than adding a new nav item. **2026-07-15, rebuilt twice this session — see the two same-day entries below for the full history; current state:** `/new` is now Category → Subcategory (always visible, disabled with "No subcategories" when the category has none) → Brand → a checkbox-driven **variant builder** sourced live from `variantCategoriesApi`, with no SKU/Name/Description/Default vendor/Tax class/Item type/Tracking mode/Base UOM fields left on the form at all (Item type/tracking mode/base UOM are now fixed constants — `"Stocked"`/`"None"`/`uomId 1` — baked into the submit call, not user-facing). Checking a category (Color, Size, or any custom one) reveals its value-entry UI; Color gets a native color picker + a required name field (stored internally as `"name|hex"`, decoded everywhere it's displayed/used for SKU) while every other category is free-text chips. A flat table (one column per checked category + SKU + Quantity) generalizes to any number of active categories via a cartesian-product `useMemo`, replacing the earlier hardcoded 2-column Color×Size matrix. Submitting loops `itemsApi.create()` once per combination; SKU is `--...`; item name is ` - /...`. Added optional `brandId`/`initialQty` to `Item`/`CreateItemRequest`/`ItemListItem` (`types/master-data.ts`) — **deviation:** neither field is in the documented Item DTO (`docs/11-BACKEND-PHASE1.md` §2.1); `initialQty` is captured but not wired into the Stock Core ledger (informational only, no warehouse/GRN behind it). - [~] UOM + conversions (`app/dashboard/products/uoms` flat list + create dialog; conversions edited inline on the Item detail page via `PUT /items/{itemId}/uom-conversions`) — FR-MD-02/03 - [~] Categories (`app/dashboard/products/categories` indented tree view + create dialog with parent picker) — FR-MD-04. **2026-07-15:** added debounced search + Previous/Next pagination (`categoriesApi.list()` now takes `page`/`pageSize`/`q`/`sortOrder`, page size 5), matching the Vendor list's pagination pattern. - [~] Brands (`app/dashboard/products/brands` list + create/edit dialog + delete) — **not a documented FR/endpoint**; `lib/api/brands.ts` treats it as a standalone name-only master, same shape as Categories, since Item has no `brandId` in the doc. **2026-07-15:** added the same debounced search + pagination as Categories; `Item`/`CreateItemRequest`/`ItemListItem` gained `brandId` so the new-item variant builder (above) can attach a brand. - [~] Variant Categories (`app/dashboard/products/variants` list + create/edit dialog + delete) — **frontend-only, not a documented FR/endpoint.** A flat, name-only master list of variant dimensions (seeded with "Color", "Size") that the Item `/new` variant builder now genuinely drives from (see the Items bullet above) — checking a category there shows its value-entry UI, and a "+" on that same page can create a brand-new category (e.g. "Material") inline via `variantCategoriesApi.create`, which then also shows up back here. Values themselves (Red, Blue, S, M...) are still not managed on this page — only entered per-Item on `/new` — so `variant_values` (the individual Red/Blue/S/M records) still isn't a real backend entity; flag to whoever owns the backend contract if that should change. New `types/master-data.ts` (`VariantCategory`/`CreateVariantCategoryRequest`/`UpdateVariantCategoryRequest`), `lib/api/variants.ts` (`variantCategoriesApi`), `lib/validations/master-data.ts` (`validateVariantCategoryName`). Sidebar gained a "Variant" entry under Products (`components/Layouts/AppSidebar.tsx`). - [~] Vendors (`app/dashboard/vendors` list + search/status-filter + create dialog, `[id]` full edit + ETag/If-Match with 412-conflict handling + activate/deactivate) — FR-MD-06. First screen this session to exercise the ETag/`If-Match`/412 pattern end-to-end (`lib/api-client.ts`'s `ApiResult` was built earlier but unused until now). - [~] Warehouses + Bins (`app/dashboard/warehouse` list + create-warehouse dialog, `[id]` bin list + create-bin dialog) — FR-WH-01/FR-MD-07. Frontend-only (see note below); no ETag handling since there's no edit/delete yet, only create. - [~] Item reorder settings — edited inline on the Item detail page (per-warehouse point/qty rows) via `PUT /items/{itemId}/reorder` — FR-MD-05 ## 3. Procurement screens - [~] Requisition (`app/dashboard/procurement/requisitions` list, `/new` create, `/[id]` detail + Submit) — FR-PROC-01 - [~] RFQ + quotations + comparison view (`.../rfqs` list, `/new` create with vendor multi-invite, `/[id]` detail: lines, comparison matrix, record-quotation form, "Create PO from vendor") — FR-PROC-02 - [~] Purchase Order (`.../purchase-orders` list, `/new` create — **Save as draft** or **Create & submit** (auto-approve), prefillable from a Requisition or an RFQ+vendor quotation via query params — `/[id]` detail: **Draft** is editable (ETag/If-Match) with **Submit** + **Delete**; a submitted/open PO is read-only with **Cancel** (with reason)) — FR-PROC-03..07. **2026-07-20:** rewired to the draft lifecycle — `isPoEditable` is now `Draft`-only, `submit`/`remove` added to `lib/api/purchase-orders.ts`, `saveAsDraft` on the create request. See the 2026-07-20 entry. - [~] Purchase Return (`.../purchase-returns` list, `/new` create against a Confirmed/Closed GRN's lines) — FR-PROC-08; also reachable from a `Rejected` GRN line via a "Create Return" button on the GRN detail page ## 4. Receiving screens - [~] GRN list (`app/dashboard/receiving/grn/page.tsx`) — loading/empty/error states, links to detail - [~] GRN create (`app/dashboard/receiving/grn/new/page.tsx`) — "Against PO" (picks an Approved/PartiallyReceived PO, prefills open lines) and "Direct receipt" (vendor + manual lines) modes; per-line bin, qty, unit cost, **discount % / VAT %** (with live after-discount/after-VAT line total + a per-row PO-price variance hint and a document total), hold status, and batch (batchNo+expiryDate) or serial-number-list capture driven by the item's `trackingMode`. **2026-07-20:** discount/VAT/variance added — see the 2026-07-20 entry. **2026-07-22:** "Add line" now works in **PO mode** (off-PO items) + **"New item"** (opens `/dashboard/products/new` in a new tab) + **refresh** icon — see the 2026-07-22 entry. - [~] GRN confirm (`app/dashboard/receiving/grn/[id]/page.tsx`) — renders returned `createdLayers`/`ledgerRefs`/`poStatus` as a confirmation panel (20-FRONTEND §4); sends a stable `Idempotency-Key` per detail-page session - [~] Inspection hold release / reject — Release/Reject buttons per on-hold line, shown once the GRN is `Confirmed` - Sidebar: added "Receiving" nav entry (`components/Layouts/AppSidebar.tsx`) → `/dashboard/receiving/grn` > **⚠️ The two notes below are HISTORY (2026-07-13).** The GRN backend exists and these screens call it as of 2026-07-17; `GET /grns` + `GET /grns/{id}` are real, and GRN edit/delete were removed because the API has no `PUT`/`DELETE`. The FIFO engine they describe as living in `mock-data.ts` is deleted — the server owns it. > > **`[~]` not `[x]`, by design (at the time):** these screens are built against the documented+planned contract in `docs/11-BACKEND-PHASE1.md` §4, but **no GRN backend existed yet** (this was frontend-only work; see the deviation below). > > **UI-only / mock-data mode (temporary):** `lib/api/{grns,purchase-orders,warehouses,items,vendors,uoms}.ts` currently return **in-memory sample data** (`lib/api/mock-data.ts`) instead of calling the real API, so the three screens are fully browsable/demoable (list → create against a mocked PO or as a direct receipt → detail → confirm → release/reject) without a running backend. Each `lib/api/*.ts` file keeps the real `fetch`-based implementation **commented out directly above** the mock block — switch back by deleting the mock block, uncommenting the real block, and deleting `lib/api/mock-data.ts` once the GRN backend exists. `npm run dev` + `tsc --noEmit` + `eslint` are clean (aside from the pre-existing, unrelated `app/login/page.tsx` resolver-typing error and the two `react-hooks/set-state-in-effect` warnings shared with `hooks/use-mobile.ts`). > > **Deviation — `GET /grns` and `GET /grns/{id}`:** the API doc only specifies `POST /grns`, `POST /grns/{id}/confirm`, `POST /grns/{id}/lines/{id}/release` (no list/detail read). A list screen and a confirm/release screen both need to reload a GRN, so `lib/api/grns.ts` (`grnsApi.list`/`grnsApi.get`) and `types/grn.ts` assume these two GET endpoints will exist once the backend is built — flag this to whoever implements `Backend/PROGRESS.md` §3 so `docs/11-BACKEND-PHASE1.md` gets the corresponding doc update. ## 5. Stock screens - [~] Stock hub (`app/dashboard/stock/page.tsx`) — card grid linking to all 7 areas below - [~] Stock enquiry (`.../stock/enquiry`) — onHand/available/onHold/inTransit/reserved, search by SKU/name + warehouse filter, links to Valuation per row - [~] Ledger view (`.../stock/ledger`) — filterable by item/warehouse/date range, paginated - [~] Valuation view (`.../stock/valuation`) — item+warehouse picker (also reachable via `?itemId=&warehouseId=` from Enquiry), FIFO layer breakdown + totals - [~] Transfer (`.../stock/transfers` list, `/new` create, `/[id]` dispatch → receive) — cost-preserving per line (FR-STK-06) - [~] Adjustment (`.../stock/adjustments` list, `/new` create) — reason code mandatory, auto-posts on submit (no separate confirm step, matching FR-STK-07) - [~] Count (`.../stock/counts` list, `/new` create, `/[id]` enter counts → post) — posting creates a linked variance adjustment - [~] Reorder alerts (`.../stock/reorder-alerts`) — items ≤ reorder point, one-click "Create requisition" - [~] Wastage (`.../stock/wastage` report, `/new` record) — **not a documented endpoint or SRS document type**: damage/theft-loss/expiry write-offs are modeled as Stock Adjustments with a loss-type reason code (FR-STK-07); `lib/api/wastage.ts` is a frontend-only lens over `stockAdjustmentsApi` + the shared mock ledger (filters to reason codes `DMG`/`LOSS`/`EXPWO`, flattens adjustment lines to per-item wastage records, sums matching outbound ledger entries for cost). No new backend concept — confirmed with the user before building (asked whether "Wastage" meant this vs. a distinct document type). - Sidebar: added "Stock" nav entry (`components/Layouts/AppSidebar.tsx`) → `/dashboard/stock`; top-bar titles mapped per route (`components/Layouts/Header.tsx`) > **⚠️ HISTORY (2026-07-13).** The Stock Core backend exists and these screens call it as of 2026-07-17; the list endpoints assumed here (`GET /stock-transfers`, `/stock-adjustments`, `/stock-counts`, on-hand list) were all added for real. The in-memory Stock Core described below is deleted. > > **`[~]` not `[x]`, by design (at the time) — same posture as §4 Receiving:** built frontend-only (user request), against the documented+assumed Stock Core contract (`docs/11-BACKEND-PHASE1.md` §5), with **no real backend**. Unlike Receiving, though, this pass wired a genuine in-memory Stock Core (`lib/api/mock-data.ts`: `mockStockLayers`, `mockStockLedger`, `receiveLayer`/`consumeFifo`/`postLedgerEntry`/`computeOnHand`) that GRN confirm now posts through too (previously GRN confirm fabricated a throwaway response; it now creates real layers/ledger entries and accrues PO `qtyReceived`/status) — so Enquiry/Ledger/Valuation reflect what actually happened in the session, and FIFO consumption (transfers, adjustment decreases, count variance decreases) genuinely throws a `STOCK_NEGATIVE_BLOCKED`-style error when stock is insufficient. `tsc --noEmit` and `eslint` are clean across all new/changed files (only the pre-existing `login/page.tsx` error and the established `set-state-in-effect` warnings remain, same as §4). > > **Deviations (same pattern as GRN, see §4):** `GET`/detail list endpoints for transfers/adjustments/counts (`lib/api/stock-transfers.ts`, `stock-adjustments.ts`, `stock-counts.ts`) are assumed extensions beyond `docs/11-BACKEND-PHASE1.md` §5.4-5.6, which document only the transactional POSTs/PUT. `stockApi.onHandList()` (used by the Enquiry screen) is also not a documented endpoint — it's a frontend-only convenience that iterates known item/warehouse pairs and calls the (documented) on-hand computation per pair; a real backend would want a proper list endpoint instead. Flag all of these to whoever implements `Backend/PROGRESS.md` §4/§5 (Stock Core + stock transactions). > > **Simplifications (mock-data limitations, not spec decisions):** `StockLayer` has no per-bin field (matches the real ER model, docs/10 Part C.5 — only `StockLedger` carries `bin_id`), so Count lines don't attempt bin-level snapshotting. Transfers don't expose batch selection in the create UI (FIFO picks layers regardless of batch). Adjustment increases always cost at "last known cost" for that item/warehouse (FR-STK-07); there's no landed-cost/manual-cost override. In-transit quantity is shown for visibility at the destination warehouse only and is not subtracted a second time from the source's `available` (dispatch already reduced the source layer's `qtyRemaining`) — the docs' `available = onHand − onHold − reserved − inTransit(out)` formula is ambiguous on this point given dispatch semantics; this was a judgment call, noted here for whoever builds the real backend to confirm or correct. ## 6. Validation posture (20-FRONTEND §3) - [~] Client format/required/range checks on all forms — done for GRN create (`lib/validations/grn.ts`); not yet done for other forms - [x] Surface server `ProblemDetails` incl. domain codes; map to fields/messages — `lib/error-map.ts` (`errorMessage`/`fieldErrors`), used by GRN create/detail - [ ] `412` conflict → prompt refetch before retry — `apiRequestWithETag` surfaces the ETag but no screen edits a GRN yet (GRN has no PUT), so untested in practice - [x] No client-side gating on stock/availability/status (server-authoritative) — GRN create always submits to the server and surfaces `OVER_RECEIPT_TOLERANCE`/etc. via `error-map.ts` rather than pre-blocking ## 7. UX states - [~] Loading / empty / error states on every list — done for the GRN list/create/detail screens; other screens still unbuilt - [x] Transactional actions show server-returned side effects as confirmation — GRN confirm renders `createdLayers`/`ledgerRefs`/`poStatus` from the response --- # HRM (Phase 2) Spec: `docs/21-FRONTEND-HRM.md` (flows + rules) · `docs/13-BACKEND-HRM-API.md` (API contract). ## 8. Screens (per `21-FRONTEND-HRM.md §1`) > **Code complete (2026-07-23).** All screens below built against the live HRM API (`lib/api/{employees,hrm-masters,hrm-master-factory,attendance,leave,payroll,hr-reports}.ts`, `types/hrm.ts`). `tsc --noEmit` clean for every new/changed file (the only remaining project-wide tsc errors are pre-existing, unrelated syntax errors in `app/dashboard/receiving/grn/new/page.tsx` — not touched this pass, not introduced by it). `eslint` clean on all new/changed files. Runtime browser verification not yet done — see the note at the end of this section. - [x] Employees (`app/dashboard/hrm/employees/{page,[id]/page}.tsx`) — list + create dialog (department/designation/employment-type/work-shift selects) + detail page with an Overview/Bank Details/Documents/Salary & Loans tab switcher (plain button-based tabs — no `Tabs` primitive exists in `components/ui/` yet). Email-lookup cross-link suggestion chip on the create dialog's email field (`onBlur` → `employeesApi.emailLookup`), never auto-linking — the human must have already seen the match before `linkUserId` is set on submit. - [x] **Salary & Loans tab** (added same session, follow-up to the initial pass) — Salary Structure section shows effective-dated history (`employeesApi.salaryStructureHistory`) + a "New Structure" dialog (effective date, basic salary, dynamic allowance/deduction lines picked from `salaryComponentsApi`, `employeesApi.createSalaryStructure`); Loans & Advances section shows the loan list (`employeesApi.listLoans`) + a "New Loan" dialog (Loan/Advance, principal, installment amount, count, start year/month, `employeesApi.createLoan`). - [x] Users screen (`app/dashboard/settings/users/page.tsx`) extended with the same cross-link suggestion chip in reverse (`employeeCrossLinkApi.findStaffByEmail` on email blur), setting `linkEmployeeId` on submit. `ManagedUser`/`CreateUserRequest` types extended with `email`/`linkEmployeeId` to match the backend DTO changes. - [x] Attendance (`app/dashboard/hrm/attendance/{page,[id]/page}.tsx`) — batch list + upload dialog (period start/end + file picker, `.xlsx`/`.csv`) + template download link (`attendanceTemplateUrl()`) + detail page rendering the Working Hours/Late/OT preview table with per-row validation-status badges, Validate/Confirm/Unlock actions gated on batch status, and Keep/Discard duplicate-resolution buttons (Draft only). - [x] Leave (`app/dashboard/hrm/leave/page.tsx`) — single-page request list + create dialog (employee/leave-type selects, immediately submits after create) + inline Approve/Reject actions on Submitted rows (reject via a `window.prompt` for the reason — the simplest correct UX given the time budget; a proper dialog is a nicer follow-up, not a correctness gap). - [x] Payroll (`app/dashboard/hrm/payroll/{page,[id]/page,[id]/lines/[lineId]/page}.tsx`) — run list + Generate dialog (year/month), detail page rendering the exact Basic/OT/Allowances/Deductions/Net preview table plus Approve/Lock/Unlock(with mandatory reason)/Generate Payslips actions gated on `status`, and a line-breakdown page matching the user's exact Earnings/Deductions/Employer-Contributions layout (EPF-employer/ETF explicitly labeled "informational — not deducted"). **Backend gap found and fixed during this pass**: there was no endpoint to list all `PayrollLine`s for a run (only single-line lookup existed) — added `GET /payroll-runs/{id}/lines` (`IPayrollRunService.ListLinesAsync`, `PayrollRunsController.ListLines`) since the Payroll Preview table genuinely needs it; documented in `docs/13-BACKEND-HRM-API.md §6`. - [x] Reports (`app/dashboard/hrm/reports/page.tsx`) — single page, a report-type select switches which filter fields + table are shown (Attendance Summary / Overtime / Late Arrivals / Payroll Register / Salary History / Leave Balances / Document Expiry), each calling its own `hrReportsApi` method on demand. - [x] Settings screens (`app/dashboard/hrm/settings/{page,branches,departments,designations,employment-types,work-shifts,document-types,leave-types,salary-components,statutory}/page.tsx`) — a hub page linking to 9 sub-screens. `components/hrm/CodeNameMasterPage.tsx` is a shared generic component for the three byte-identical "code + name" masters (Branch, Designation, EmploymentType) — the other masters (Department's parent/branch selects, WorkShift's many fields + working-days bitmask, HrDocumentType's category enum, LeaveType's paid/no-pay/carry-forward flags, SalaryComponent's type enum) each have their own page since their forms genuinely differ, matching this codebase's own existing convention of one file per master rather than a forced one-size-fits-all abstraction. Statutory settings page covers both `PayrollStatutorySetting` and `TaxSlab` (list + create, no edit — both are effective-dated/append-only by design). - [x] Sidebar (`components/Layouts/AppSidebar.tsx`) — new "HRM" section with 6 children (Employees/Attendance/Leave/Payroll/Reports/Settings). **Deviation, matching existing precedent**: no backend `NavItem`/`SubNavItem` seed exists for `hrm`/`hrm.*` codes yet, so — exactly like the pre-existing `procurement` bypass — `hrm` is added to the same frontend-only `bypassCodes` set that skips the `navCodes` visibility check. This is also the AR-09 sidebar-visibility stopgap called out in `02-SECURITY.md §C.8`: it hides HRM from the UI for now but enforces nothing server-side. Remove the bypass once a real nav/permission seed exists. - [x] `lib/api-client.ts` extended to support `FormData` request bodies (attendance file upload, staff document upload) — previously every request body was unconditionally `JSON.stringify`'d; now a `FormData` body skips both that and the `Content-Type` header (the browser sets its own multipart boundary). ## 9. Validation posture (HRM specifics, per `21-FRONTEND-HRM.md §3`) - [x] Client format/required checks on the Employee create dialog (code/name/hire-date/department/designation/employment-type/work-shift) and Attendance upload (period dates, file presence) — UX only, per `20-FRONTEND.md §3` - [x] Server-authoritative, never assumed client-side: employee-code uniqueness, email-lookup match existence, one-User-per-Employee, attendance duplicate detection (within-batch/cross-batch), attendance batch lock state, payroll generation's attendance-confirmed precondition, payroll run lock state, and every calculated amount (Gross/Net/Tax/EPF/ETF/OT/Late/No-Pay) — the client never computes or previews these independently of what the server returns; all payroll tables render server-supplied numbers verbatim. **Not yet done, flagged rather than silently skipped:** - **Runtime/browser verification.** Every screen above type-checks and lints clean, and was built directly against the live API contract confirmed by the backend smoke test (71+ registered routes, correct 401 gating), but no screen has been driven in an actual browser this pass — that needs a running AuthHex session (see `Backend/PROGRESS.md`'s sub-phase 2.1 note on why deep functional testing was deferred) to get past the login wall. - **Leave reject uses a native `window.prompt`** instead of a dialog — functionally correct, but a lower-fidelity UX than the rest of the app's dialog-based patterns. - **A pre-existing, unrelated syntax error in `app/dashboard/receiving/grn/new/page.tsx`** (unclosed JSX, last touched 2026-07-23 before this HRM pass started) blocks a clean whole-project `tsc --noEmit` run. Not introduced by this work and not fixed by it — confirmed via `git status`/`git log` that this file was untouched this session; scoped `eslint`/`tsc` checks against every HRM file individually (and the fact this is the *only* file `tsc` reports) confirm the HRM additions themselves are clean. --- # Manufacturing — Production Lines (Phase 2) Spec: `docs/21-FRONTEND-PHASE2.md` (flows/screens) · contract: `docs/30-BACKEND-PHASE2.md` (§D.1–D.3). Validation posture: `docs/20-FRONTEND.md §3` — client checks are UX only. > **Every production screen now runs on the real API. Both mock modules are deleted.** `npx tsc --noEmit` reports 0 errors in this module (the only 4 project errors are pre-existing HRM ones — see the note at the end of §13), and `npx next build` reports **"Compiled successfully"** before failing type-check on those same HRM files. **Nothing has been driven in a browser** — see the honesty note at the end. ## 11. Contract layer (F1) — DONE - [x] `types/production.ts` **fully rewritten** against docs/30 Part D — every request/response DTO, all six enums, and the stage-action result shapes. Replaces the frontend-only placeholder shapes entirely - [x] Three contract corrections carried through: templates are keyed by **`code`** (not `docNo` — only runs get a document number); quantities use **`itemId`/`uomId`/`qtyPerBatch`** numeric FKs (not free-text uom/qty); stages carry **`posX`/`posY`**, so canvas layout round-trips through the server - [x] `lib/api/production-templates.ts` — list/get/create/update/updateStatus with ETag + `If-Match` - [x] `lib/api/production-runs.ts` — the full §D.3 surface (start, complete, approve, transfer, reject-intake, reject, return-leftover, cancel, quantities), every action taking an `idempotencyKey`; plus `isStaleStageError()` for the docs/21 §6 "409 on a stage-status code → refetch silently" rule - [x] `lib/error-map.ts` — all 17 docs/30 §D.4 codes. **Also fixed a real mechanism gap:** `errorMessage()` let any mapped domain code override the server's `detail`, which would have thrown away the specifics the user needs — the graph validator names the offending stages, and the transfer/leftover guards quote the actual figures. Added `DETAIL_PREFERRED_CODES` so those eight codes let `detail` win and keep their map entry as a fallback ## 12. Screens (F2–F5) — DONE - [x] **Template overview** (`app/dashboard/production/templates/page.tsx`) — real `productionTemplatesApi.list` with a 300 ms debounced search, status filter, pagination and real `activeRunCount`. One-row-per-template canvas labelled from live data - [x] **Template builder** (`templates/[id]/page.tsx`) — **fully rewired.** GETs the graph, holds the ETag, and the former `handleSave()` toast stub is now a real create/update. Node ids **are** the server's stage keys (`tmp-` for stages drawn this session), so a PUT diffs stages in place and keeps historical runs linked; `node.position` persists as `posX`/`posY`; real `itemsApi`/`uomsApi` pickers replaced `MOCK_ITEMS`; `/templates/new` renders an unsaved draft seeded from the overview dialog's query params and swaps its URL on first save. Also gained a Deactivate/Activate control — `productionTemplatesApi.updateStatus` previously had no UI path at all - [x] **Run board** (`runs/page.tsx`) — real list with debounced doc-no search, template/warehouse/status filters and pagination. Start dialog posts `productionRunsApi.create` and **navigates to the run** - [x] **Run detail** (`runs/[id]/page.tsx`) — canvas built from the run's own `posX`/`posY` and run edges, with per-stage intake (`delivered/planned`) and available-to-transfer badges, live cost pool, and a `stageSummary` computed from real stage statuses - [x] **Stage drawer** (`runs/[id]/StageDrawer.tsx`) — the whole of docs/21 §5: per-status bodies (Waiting → explanation · Ready → editable planned quantities + Start · InProgress → produced/scrapped per output with a required Production reason + custom fields + Complete · Done non-terminal → approve with optional partial transfer · Done terminal → receipt preview + Approve & receive + Reject for rework · Approved → transfer remainder), reject-intake from Ready **or** Waiting-with-deliveries, and the per-stage event timeline - [x] **Runtime custom-field renderer** (`runs/[id]/CustomFieldForm.tsx`) — `fieldDefs` → typed inputs for all five types, plus `missingRequiredFields()` which **mirrors the server's rule exactly**, including the part that surprises people: an unchecked Checkbox counts as *provided* (`false`), so a required checkbox does not force a tick - [x] **Run-level actions** (`runs/[id]/RunActions.tsx`) — Return leftover (per consumed Stock input, showing consumed/returned/weighted cost, in base UOM and capped at the unreturned remainder) and Cancel run (previewing what goes back to stock). Both hidden once the run leaves InProgress, because `RUN_COST_CLOSED`/`RUN_NOT_CANCELLABLE` mean offering them could only produce an error - [x] `lib/production-status-colors.ts` kept untouched — it already matches docs/21 §3 exactly and is the single source for status colour everywhere - [x] **Deleted `lib/production-mock-runs.ts` and `lib/production-mock-templates.ts`**, including `buildStagePlan()` **Deviations / decisions (recorded):** - **The drawer is one file, not the seven the plan sketched.** Each per-status panel is ~30 lines and they all share the same lookup helpers, `submit()` wrapper and error handling; splitting them would mean threading that shared context through seven prop lists for no isolation benefit. `CustomFieldForm` and `RunActions` *are* separate, because both stand alone and neither needs the drawer's form state. - **The board shows per-status counts, not named stages.** The list projection carries `stageSummary` only, so naming stages there would mean guessing which stage holds which count — exactly what the deleted `buildStagePlan()` did. Named per-stage state lives on the run detail, where the server actually returns it. - **Non-terminal outputs have their `itemId` stripped on save, not rejected.** A stage that *was* terminal and then gained a child keeps its picked item in local state with the field no longer rendered; an issue-list message about an invisible field would be unactionable, so the builder drops it silently (FR-MFG-05 forbids it on a WIP output anyway). - **The terminal receipt preview is computed client-side.** There is no preview endpoint and every input (cost pool, produced, scrapped) is already on the page, so the drawer mirrors the server's arithmetic to show the layer *before* creating it. Preview only — the server recomputes. - **A status toggle re-reads the ETag.** `PATCH /status` bumps the row's `xmin`, invalidating the token the builder holds. It re-GETs and takes *only* the etag and status, deliberately not reloading the canvas, because a full reload there would silently discard unsaved edits. - **"New Template" opens an unsaved draft rather than creating immediately.** A template cannot exist without a valid graph — the server requires ≥1 stage and a terminal output naming a real item (FR-MFG-02/05) — so there is nothing sensible to POST from a name alone. - **`templateGraphToSaveRequest()` was deleted from `lib/api/production-templates.ts`.** It converted a fetched graph into a save payload, but the builder's canvas — not the last GET — is the source of truth for what gets saved, so it had no caller and would have drifted. **Backend additions made for these screens** (all amended into docs/30 as built): - **`TemplateSummaryDto.stageNames`, in flow order.** The overview draws each template as a line left-to-right and needs the names for every row; without the field the client would fetch every template's full graph just to label boxes. Ordering by stage id turned out to be insertion order, which put the *terminal* stage first and drew lines backwards — so the server toposorts (Kahn, tie-broken by id for stability, falling back to id order if the graph is ever cyclic so a listing can't fail on bad data). - **`TemplateGraphDto.activeRunCount`.** The builder reads its edit-locked state straight off the graph; without it, it would need a second request to the list endpoint purely to know whether to disable itself. - **`production_templates.Annotations` (jsonb) + `SaveTemplateRequest.annotations`.** The canvas already drew grouping boxes and divider lines and the contract had nowhere to keep them, so every save would have silently discarded the user's layout notes. Round-tripped verbatim, capped at 200 entries, `kind` validated to `box`/`line`, and invisible to the graph validator. Migration `AddTemplateCanvasAnnotations`. Note the flip side, pinned by a smoke assertion: replacement is wholesale, so a client that forgets to echo `annotations` back on a PUT clears them. ## 13. Validation posture (F6) — DONE - [x] Domain-code → message map complete (§11), with `detail` preferred where the server is more specific - [x] `412 CONCURRENCY_CONFLICT` amber conflict banner + Reload on the builder (the `app/dashboard/vendors/[id]/page.tsx` pattern) - [x] `409 TEMPLATE_IN_USE` edit-lock banner driven by the server. Two distinct messages: locked on load (`activeRunCount > 0`) versus locked *while editing* — the FR-MFG-06 TOCTOU, where a run starts between the GET and the PUT. The second locks the canvas rather than reloading, so nothing the user just drew disappears without an explanation - [x] `422 GRAPH_*` focuses the offending stage — a best-effort substring match of the server's `detail` against stage names, which is why the validator quotes them. Advisory by design: the full message is always in the banner too, so an ambiguous name costs a highlight, never the explanation - [x] `Idempotency-Key` per action (`useRef(crypto.randomUUID())`, re-minted after each success and whenever the drawer switches stage) - [x] Silent refetch on stage-status 409s — `submit()` in the drawer routes every action through `isStaleStageError()` **Not done, flagged rather than silently skipped:** - **No browser verification of any production screen, and no live end-to-end run.** The contract layer is written against a backend whose every endpoint is smoke-verified, the tree type-checks and Turbopack compiles it, but **nothing has been clicked.** Blocked on AuthHex: its configured MySQL host (`187.127.102.190:3306`) is unreachable from this machine, so no token can be issued — which also means the backend smoke suite could not be re-run after this pass's backend additions. - **`components/Layouts/AppSidebar.tsx:351` still lists `"production"` in `bypassCodes`.** Correct for now — no role is seeded with a `NAV:production` permission, so removing the bypass would hide the section from everyone. Seeding that permission is the real fix (same outstanding item as `procurement`/`hrm`). - **4 pre-existing `tsc` errors, unrelated to this work — and they block `next build` for the whole app:** `hrm/employees/[id]/page.tsx` (`UpdateEmployeeRequest` missing `hireDate`) and three `hrm/settings/*` pages (an `Api` generic expecting `{value}` where `ApiResult` is returned). None of these files import anything added or changed by this pass, so they were left alone rather than fixed as a side effect of manufacturing work. - **10 `react-hooks/set-state-in-effect` lint errors across the five production files.** Same rule fires 42 times repo-wide (`app/dashboard/receiving/grn/page.tsx` included); these are the load effects, the hydration-mismatch guards and the builder's stale-upstream repair. No other rule fires in this module. ## Done ### 2026-07-28 — Dashboard overview (`app/dashboard/page.tsx`) - **Replaced the component-showcase placeholder with a real stats dashboard.** 7 `StatCard` tiles (Low Stock Alerts, Stock On-Hand, Pending Approval POs, Pending GRNs, Open Requisitions, Open Counts, Active RFQs), all wired to the new `GET /dashboard/stats` (`lib/api/dashboard.ts`, `types/dashboard.ts`) — see `Backend/PROGRESS.md`'s matching 2026-07-28 entry for the endpoint itself. Each tile links to its source list page. - **Stock Valuation by Warehouse** — `BarChart` over `stats.stockValuationByWarehouse`, warehouse codes resolved via `warehousesApi.list()`. - **Stock Movement Trend** — `LineChart`, 14-day In/Out totals bucketed client-side from `GET /stock/ledger?from=...&pageSize=200`. **Falls back to a hardcoded sample series (`SAMPLE_TREND_IN`/`OUT`) when the real ledger has no activity in that window**, so the chart isn't a flat zero line on a fresh/demo database — real data always wins when present. (An equivalent fallback was added to the Recent Stock Movements table during this pass and then explicitly removed at the user's request — that table shows only real data + an empty state.) - **Recent Stock Movements** — table of the latest 5 ledger entries; shows `#itemId` rather than the item SKU, deliberately, to avoid a hard dependency on `GET /items` (see the bug below). - **`StatCard` (`components/ui/stat-card.tsx`) fixed to use theme tokens** — it previously hardcoded `bg-white`/`text-slate-900`/`text-indigo-600`/`ring-black/5`, which was invisible-on-dark once the Dark/Vibrant themes existed. Now `bg-card`/`text-foreground`/`text-primary`/`ring-foreground/10`. - **Bug found — `GET /items` 500s on every call** (`column i.SalePrice does not exist`) — this is why the dashboard and the movements table avoid `itemsApi` entirely. Root cause + fix status tracked in `Backend/PROGRESS.md`'s 2026-07-28 entry; **not yet fixed** as of this entry. - **Chart color gotcha (found and fixed twice this session):** passing a CSS custom property or `color-mix()` string (e.g. `"var(--color-primary)"`) as a Chart.js `borderColor`/`backgroundColor` silently renders **black**, because a `` 2D context cannot resolve CSS variables — it's not a themeable value, it's an invalid string that falls back to the default. Every chart on this page uses real static hex colors instead (`#6366f1`, `#22c55e`, `#ef4444`). - **Verified:** `tsc --noEmit` clean throughout. Runtime verification blocked for most of this session by the dev backend running under an active Visual Studio debug session — killing the process externally just triggers VS's own auto-relaunch of the **stale** build (observed repeatedly; confirmed via process start-time checks), so `dotnet build`/`dotnet ef` against the live `bin/`/`obj/` failed on file locks. Worked around by building to an isolated `-o` output directory to verify compilation without touching the locked live build; **actually deploying a rebuild still requires stopping debugging inside Visual Studio itself** (not just closing a console window) — this blocked full end-to-end verification of `/dashboard/stats` until the user did that. ### 2026-07-22 — Item fixed sale price + GRN off-PO items / inline create - **Item sale-price toggle** (`app/dashboard/products/new/page.tsx`). New "Fixed price / Use stock value" segmented toggle (default **stock**). **Stock** sends `salePrice: null` on every created item. **Fixed** reveals a top "fix value" input that pre-fills a per-variant **Sale price** column (`priceFor(key) = pricesByKey[key] ?? fixValue`, so editing a row overrides only it while the rest follow the shared value); submit is blocked until **every** generated variant has a price `> 0` (`validateVariantPrices` in `lib/validations/master-data.ts`). Each variant's price rides its own `POST /items` in the existing non-transactional create loop. `types/master-data.ts`: `salePrice` added to `CreateItemRequest` (optional) and `Item`/`ItemListItem` (`number|null`). - **GRN off-PO items + inline create** (`app/dashboard/receiving/grn/new/page.tsx`). "Add line" is now shown in **both** PO and direct mode — an added PO-mode line has `poLineId: null` (editable item/UOM, `unitCost` required) and the server receives it as a direct line. New **"New item"** button opens `/dashboard/products/new` in a new browser tab (`window.open(..., "_blank", "noopener,noreferrer")` — the first new-tab pattern in the app), and a **refresh** icon (`refreshItems`) re-pulls `GET /items?status=Active` so the new item is selectable without reloading the in-progress GRN. Existing `validateLine` covers off-PO lines unchanged. - **Verified:** `tsc --noEmit` clean. Runtime browser verification (create fixed-priced variants; add an off-PO line + inline item on a PO GRN) is the next step. ### 2026-07-20 — PO draft lifecycle + GRN discount/VAT/price-override (backend + frontend, same pass) - **PO draft lifecycle.** `lib/api/purchase-orders.ts`: `isPoEditable` narrowed to `status === "Draft"` (was the three-status exclusion); added `submit(poId)` and `remove(poId)`. `types/procurement.ts`: `saveAsDraft?` on `CreatePurchaseOrderRequest`; `UpdatePurchaseOrderRequest` now `Omit`s it. `/new`: the single "Create PO" button split into **Save as draft** / **Create & submit**. `/[id]`: **Draft** shows the editable line grid + **Submit** + **Delete draft**; an issued-but-open PO (`Approved`/`PartiallyReceived`) is read-only with **Cancel PO** (with reason, disabled once receipts exist); closed/cancelled are terminal. The old Cancel button was gated on `isPoEditable` — that would have shown Cancel only for Draft, so the affordances were re-split into `editable` (Draft) vs `cancellable` (Approved/PartiallyReceived). - **GRN discount/VAT/variance.** `types/grn.ts`: `discountPct`/`vatPct` on `CreateGrnLineInput`; `poUnitPrice`/`discountPct`/`netUnitCost`/`vatPct`/`vatAmount`/`lineTotal`/`priceVariance` on `GrnLine`. `/new`: per-line Disc %/VAT % inputs, a client mirror of the server arithmetic (`computeLine`, display-only — server stays authoritative) driving a live Line total + document total, and a PO-price variance hint when the entered unit cost differs from the prefilled PO price. `/[id]`: renders the full cost breakdown (unit cost + variance, disc %, net cost, received value, VAT, line total) and a stock-value/VAT/document-total footer. `lib/validations/grn.ts`: 0–100 range checks on the two percentages. - **Deliberately not touched:** the item picker already showed `sku — name` (the request's stated need); multi-GRN-per-PO and adding a non-PO item to a PO GRN already worked. Vendor stays PO-derived (non-selectable) for a PO-based GRN — selecting a different vendor than the PO's would be wrong. - **Select trigger showed the id, not the label (global fix).** Base UI's `Select.Value` renders the raw selected value unless the `Select.Root` is given an `items` map — the popup items unmount when closed, so their text isn't available to the trigger (confirmed in `@base-ui/react`'s `resolveSelectedLabel`, which `find`s `items` by value and only falls back to stringifying the value when none is supplied). Fixed once in the shared wrapper (`components/ui/select.tsx`): `Select` now walks its own `SelectItem` children and derives the `items` array automatically, so all ~60 `` call sites across 26 files show the selected label without any per-site change. `tsc`/`eslint` clean; verified against Base UI's label-resolution source. - **Procurement sidebar submenu.** The sidebar builds submenus from backend-seeded `SubNavItem` rows filtered by `GET /auth/me`'s `navCodes`; only Products and Settings had children, so Purchase Orders had no sidebar section (only reachable via the Procurement hub card). Added a `children` array to the Procurement nav entry (`components/Layouts/AppSidebar.tsx`) — Requisitions, RFQs, Purchase Orders, Purchase Returns — matching new backend sub-nav codes. Also found the Admin role (`RoleId 2`) was never granted `NAV:procurement` at all, so the whole Procurement branch was hidden for it; granted the parent + 4 children. **Verified:** `/auth/me` for Admin now returns all five procurement codes → submenu renders. Stale PO hub-card copy ("freely editable while open") updated to the draft/submit wording. - **Verified:** `tsc --noEmit` clean; `eslint` unchanged from baseline (7 pre-existing `set-state-in-effect` on the PO/GRN screens before and after — 0 new issues, confirmed by stashing and re-counting). Runtime browser verification is the next step in this pass. ### 2026-07-17 — connected to the real API (mock-data.ts deleted) **The app now talks to ERPCore.** Every `lib/api/*.ts` module calls the backend; `lib/api/mock-data.ts` is gone. This is the pass the 2026-07-15 note anticipated. **Transport + auth** - Same-origin **Next `rewrites()` proxy** rather than backend CORS (see §0). The backend has no CORS and now needs none. - Rebuilt `lib/api-client.ts` from `git show 0e4bcf1^`; added `credentials: "include"`. - New `proxy.ts` route guard, `lib/api/auth.ts`, `lib/auth-session.ts`, `types/auth.ts`. Login/logout are real. - **Fixed the long-standing `app/login/page.tsx` resolver type error** — `lib/validations.ts` used `z.preprocess`, which widens the schema's *input* type to `unknown`, so `zodResolver` produced a `Resolver<{email: unknown}>` that could not satisfy `useForm`. Form fields always yield strings (RHF defaults them to `""`), so the null-coercion it guarded against cannot happen. **`tsc --noEmit` is now fully clean** — the first time in this file's history. **Two real bugs found by driving the browser (both fixed, both invisible to unit-level checks)** 1. **Logout didn't log you out.** AuthHex returns `user.userId: null` on login, so the Header could not supply the `userId` that `POST /auth/logout` required; the call was skipped and `erp_at` survived. Fixed backend-side (`userId` optional, resolved from the token claim, cookies always cleared). Verified: cookies now `[]` after logout. 2. **Generic error codes shadowed the server's message.** `errorMessage()` checked `CODE_MESSAGES[code]` before `detail`, so a duplicate brand showed "This action conflicts with the record's current state." instead of "A brand named 'bosch' already exists." Generic codes (`conflict`/`not_found`/`validation_error`) now lose to `detail`. **Contract drift reconciled** (types were rewritten field-by-field against the live OpenAPI, not assumed): - `itemType` → `stockNature`; `ItemType` is now the Color/Size master. `variants.ts` → `item-types.ts`; the screen moved to `/dashboard/products/item-types`. - `RfqComparison` was `{lines[].cells[]}` in this app but `{rows[].quotes[]}` on the server, and cells carry `quotationId`. `Rfq` has no `vendorIds`/`createdAt`; `StockTransfer`/`StockCount` had `createdBy`/`createdAt` the DTOs never returned (added server-side rather than dropping the columns); `ReasonCodeContext` had `"CountVariance"` where the server says `"Count"`; `EnterCounts` returns the whole `CountDto`, not `{lines}`; `PostCountResponse.adjustmentId` is nullable; `createReorderRequisition` returns a full `Requisition`, not `{qty}`. - `remove()` → `updateStatus(id, "Inactive")` on brands/categories/item-types, each with a Status column and Deactivate/Activate (no `DELETE` exists — FR-MD-08). - New `app/dashboard/products/categories/[id]` for subcategories (their own resource now); new `app/dashboard/products/settings` for Product Configuration (added the shadcn `switch` primitive via the CLI). **Features deliberately removed rather than left lying** - **`initialQty`** and the builder's Quantity column — no such field on the Item contract and no initial-receipt flow; stock arrives via a GRN. It never worked under the mock either. - **GRN edit/delete** + the `grn/[id]/edit` route — the API has no `PUT`/`DELETE` for a GRN (FR-X-05). - **RFQ "vendors invited"** — not persisted server-side. The screens show quotations received; the quote form offers any active vendor instead of "invited but pending". - **Serial capture on GRN** — `CreateGrnLineInput` has no serial field despite FR-GRN-04 (priority M). Not collected rather than silently discarded. Flagged in `Backend/PROGRESS.md` + docs/11 §4. **Fixed while rewiring:** the builder hardcoded `baseUomId: 1`, which only worked because the mock seeded that id — against a real DB it is a 422 or, worse, the wrong unit. It now adopts the first real UOM and says so when none exists. The per-row create loop still has no transaction, but the error now reports how many items landed before the failure instead of implying none did. **Verified end-to-end in a real browser (Playwright), not just typechecked** — 17/17 then 9/9 on a recheck: guard redirect + `?next=` round-trip; login → cookies (`erp_at` httpOnly) → real user in Header; brand created via the UI; **duplicate → server 409 with its own message**; product-config screen reads the singleton; item-types shows the seeded Color/Size; logout clears cookies. Plus, through the page's own session: **cross-FK guard 422** (*"Subcategory 5 belongs to category 10, not 11"*), item created with **both** `categoryId` and `subCategoryId` + `brandId`, `conversions` present on the detail, **`CONFIG_DISABLED` 422** with the same item succeeding without the gated field and pre-existing items still readable, and a stale `If-Match` → **412 `CONCURRENCY_CONFLICT`**. Test data was removed afterwards; the dev DB is back to empty masters. > **The DB is near-empty and that is now visible.** The mock silently supplied warehouses, UOMs, reason codes and sample POs. Screens are blank until that data is created — correct behaviour, not a regression, but a dev seed would make the app pleasant to open. `lib/api/mock-data.ts`'s FIFO engine (`receiveLayer`/`consumeFifo`/`postLedgerEntry`/`computeOnHand`) is gone with it: **the browser no longer does inventory maths** — the server does. > > **Not yet exercised against real data:** GRN confirm → Stock Enquiry/Ledger/Valuation, transfers, counts and the wastage report. They compile and are wired, but proving the FIFO chain needs a warehouse + PO + receipt seeded first. That is the highest-value next verification. ### 2026-07-13 — GRN screens + frontend foundation (frontend-only; no backend changes) - Foundation: `lib/api-client.ts`, `lib/error-map.ts`, `lib/auth-token.ts`, `types/{common,master-data,procurement,grn}.ts`, `lib/api/{grns,purchase-orders,warehouses,items,vendors,uoms}.ts` — scoped to what the GRN flow needs, not the full API surface. - Added the shadcn `select` primitive (`npx shadcn add select`) — wasn't in `components/ui/` yet; needed for PO/vendor/warehouse/bin/item/hold-status pickers. - Screens: GRN list, GRN create (PO-based + direct receipt, batch/serial capture by `trackingMode`), GRN detail (confirm + release/reject). Sidebar nav entry added. - **This was explicitly frontend-only** (user interrupted an initial backend+frontend plan and asked for frontend only). No GRN backend exists — `Backend/PROGRESS.md` §3/§4 are unchanged. The screens are built against the contract in `docs/11-BACKEND-PHASE1.md` §4 plus two assumed-but-undocumented endpoints (`GET /grns`, `GET /grns/{id}`, see §4 note above); none of it is runnable end-to-end yet. - Verified: `tsc --noEmit` clean for all new/edited files (one pre-existing, unrelated error remains in `app/login/page.tsx`); `eslint` clean aside from two `react-hooks/set-state-in-effect` warnings matching an already-existing pattern in `hooks/use-mobile.ts`; all three routes confirmed rendering (200, correct content, no error boundary) via SSR against the dev server. ### 2026-07-13 — Stock Management screens (frontend-only; no backend changes) - `types/stock.ts`: full DTO set for on-hand, ledger, valuation, transfers, adjustments, counts, reorder alerts (docs/11 §5). - `lib/api/mock-data.ts` gained a real in-memory Stock Core: `mockStockLayers`/`mockStockLedger` + `receiveLayer`/`consumeFifo`/`postLedgerEntry`/`computeOnHand`/`lastKnownCost` helpers, plus `mockItemReorders` and `mockReasonCodes` seed data. `lib/api/grns.ts`'s `confirm()` was refactored to post through these helpers instead of fabricating a response, and now also accrues PO `qtyReceived`/recomputes PO status — so GRN and Stock screens are genuinely connected this session. - New API modules: `lib/api/stock.ts` (on-hand/ledger/valuation/reorder-alerts), `stock-transfers.ts`, `stock-adjustments.ts`, `stock-counts.ts`, `reason-codes.ts` — same commented-real-block + active-mock-block pattern as the GRN modules. - Screens: hub, Enquiry, Ledger, Valuation, Transfers (list/new/detail with dispatch+receive), Adjustments (list/new, auto-post), Counts (list/new/detail with enter-counts+post), Reorder Alerts. New shared badge set `components/stock/status-badges.tsx` (same fixed-size red/green/yellow convention as `components/receiving/status-badges.tsx`). Sidebar + header-title mappings added. - Same posture as the GRN pass: `[~]` not `[x]`, frontend built ahead of a nonexistent Stock Core backend, deviations/simplifications recorded in the §5 note above. `tsc --noEmit` and `eslint` clean (only the same pre-existing/established issues as the GRN pass). ### 2026-07-13 — Wastage screens (frontend-only; no backend changes) - `lib/api/wastage.ts`: no new backend concept — confirmed with the user that "Wastage" should be a focused UI lens over the just-built Stock Adjustments (damage/theft-loss/expiry write-off reason codes), not a distinct document type. Filters `mockStockAdjustments` to loss-type reason codes, flattens to per-item `WastageRecord`s, and computes cost per record from matching outbound `mockStockLedger` entries. - Screens: `.../stock/wastage` (report — totals cards, warehouse/reason filters, per-item table) and `.../stock/wastage/new` (single-line record form, reason dropdown restricted to wastage-type codes, posts via the existing `stockAdjustmentsApi.create`). Added a "Wastage" card to the Stock hub and header-title mappings. - Verified: `tsc --noEmit` clean (same pre-existing `login/page.tsx` error only); `eslint` clean aside from one more instance of the already-established `set-state-in-effect` pattern. ### 2026-07-13 — Warehouse Management screens (frontend-only; no backend changes) - Scope, per user selection out of the four FR-WH sub-areas offered (Warehouses & Bins / Stock Locator / Batch & Serial / Putaway): **Warehouses & Bins master data only** (FR-WH-01, FR-MD-07). The other three (bin-level Stock Locator, Batch/Serial tracking, Putaway) were **not** built — flagged here so a future pass knows they're still open, not forgotten. - `lib/api/warehouses.ts` gained `create`/`get`/`createBin` (previously list/listBins only, read-only) — duplicate-code validation mirrors the real `SKU_DUPLICATE`-style 400 pattern used elsewhere. `mock-data.ts` gained `allocateWarehouseId`/`allocateBinId`. - Screens: `app/dashboard/warehouse` (list + "New Warehouse" `Dialog` form) and `app/dashboard/warehouse/[id]` (bin list + "New Bin" `Dialog` form) — used `components/ui/dialog.tsx` instead of a full page for these two-field creates, since a whole page felt heavy for that. Sidebar "Warehouses" entry + header-title mapping added. - Housekeeping: removed two stray duplicate route folders (`app/dashboard/receiving/grn/create new GRN/`, `.../view GRN/`) that were byte-for-byte copies of the real `new/` and `[id]/` GRN pages under garbled folder names — almost certainly an IDE artifact from an earlier malformed file-open path, not intentional work (confirmed untracked in git before removing). Also noted, but deliberately left alone: `app/warehouse/*`, `components/warehouse/`, `lib/warehouse/` are pre-existing **empty** scaffold folders (no files at all) from initial project setup — Warehouse Management was built under `app/dashboard/warehouse/*` instead so it gets the dashboard chrome (sidebar/header) for free, consistent with every other screen this session. - Verified: `tsc --noEmit` clean (same pre-existing `login/page.tsx` error only); `eslint` clean aside from one `exhaustive-deps` warning (not an error) on `[id]/page.tsx`'s `loadBins` helper. ### 2026-07-13 — Vendor (Supplier) management screens (frontend-only; no backend changes) - Confirmed with the user first: "supplier/shop" has no distinct "Shop" entity in the SRS/docs — scoped this to the documented Vendor master (FR-MD-06, docs/11 §2.4), "supplier" being the standard ERP synonym. - `lib/api/vendors.ts` extended from list-only to `get`/`create`/`update`/`updateStatus`. This is the **first screen to exercise the ETag/If-Match/412 pattern**: `mock-data.ts` gained a per-vendor concurrency-token map (`getVendorVersion`/`bumpVendorVersion`/`initVendorVersion`, standing in for the real backend's `xmin` — the public `Vendor` type has no version field of its own since it travels as an HTTP `ETag` header, not a body field) so `update()` genuinely rejects a stale `If-Match` with `CONCURRENCY_CONFLICT`, matching `docs/11 §1.6` and `20-FRONTEND.md §3.2`. - Screens: `app/dashboard/vendors` (list, search + status filter, "New Vendor" dialog) and `app/dashboard/vendors/[id]` (full edit form using the real `apiRequestWithETag`-shaped `ApiResult`, a dedicated conflict banner with "Reload before retrying" per the 412 UX rule rather than a generic toast, and an Activate/Deactivate toggle via `PATCH status`, FR-MD-08 — deactivate, not hard-delete). Sidebar "Vendors" entry + header-title mapping added. - Verified: `tsc --noEmit` clean (same pre-existing `login/page.tsx` error only); `eslint` clean aside from the same established `set-state-in-effect` pattern used throughout this session. - **Follow-up (same day):** `vendorsApi.list()` didn't actually paginate (always returned page 1 / all matches, same latent gap the GRN list had before its own pagination pass) — fixed to slice by `page`/`pageSize` properly, added the same Previous/Next pagination controls used on the GRN and Stock list screens, and seeded 8 more sample vendors so there's something real to page through. ### 2026-07-13 — Procurement screens: Requisition → RFQ → PO → Purchase Return (frontend-only; no backend changes) - `types/procurement.ts` grew from a GRN-support subset (PO read types only) to the full §3 DTO set: Requisition/ReqLine, Rfq/RfqLine/Quotation/RfqComparison, PO create/update/cancel request types, PurchaseReturn/PurchaseReturnLine — mirrors `docs/11-BACKEND-PHASE1.md` §3 request/response JSON exactly (no `deliveryDate` field on PO lines, since the documented `POST /purchase-orders` example doesn't carry one despite FR-PROC-03's prose — contract-over-prose per `docs/20-FRONTEND.md` §1). - `lib/api/mock-data.ts`: added `mockRequisitions`/`mockRfqs`/`mockQuotations`/`mockPurchaseReturns` + allocators, a PO concurrency-token map (`getPoVersion`/`bumpPoVersion`/`initPoVersion`, same out-of-band ETag pattern as vendors), and `consumeLayerByGrnLine` — a *new* consumption path deliberately separate from `consumeFifo`: a Purchase Return disposes of the exact layer its GRN line created (often `OnHold`/`Rejected`, which `consumeFifo`'s hold filter would otherwise skip), not "the oldest open layer for this item/warehouse". Seeded Requisition #210 to match the existing `mockPurchaseOrders[0].requisitionId` so the two screens cross-reference. - New API modules: `lib/api/requisitions.ts`, `lib/api/rfqs.ts` (create/addQuotation/comparison — comparison is computed client-side from recorded quotations), `lib/api/purchase-returns.ts`. `lib/api/purchase-orders.ts` extended from list/get-only (its original GRN-support scope) to full create/update/cancel; added `getWithETag`/`isPoEditable` without touching the existing plain `get()` GRN's create-flow already depends on, so no existing call site broke. - **Wiring, not just new screens:** `stockApi.createReorderRequisition` (Stock → Reorder Alerts, built in an earlier session) previously fabricated a response with no backing record; it now pushes a real row into `mockRequisitions`, so a reorder-triggered requisition genuinely shows up in the new Requisitions list — same "connect the mock modules together" posture as GRN confirm → Stock Core. - Screens: Requisition (list/new/detail+Submit), RFQ (list/new with checkbox vendor multi-invite reusing the Stock Count's `Checkbox` pattern/new with quotation-recording form + vendor-by-line comparison table/"Create PO from vendor"), Purchase Order (list/new — accepts `?requisitionId=` or `?rfqId=&vendorId=` to prefill lines and pricing/detail with inline edit-while-open using the vendor `[id]` page's ETag+412-conflict-banner pattern, plus a Cancel-with-reason flow client-disabled when any line has receipts), Purchase Return (list/new — pick a Confirmed/Closed GRN, checkbox+qty its lines; also reachable via a new "Create Return" button next to `Rejected` lines on the GRN detail page, matching the SRS flow diagram's Reject→Purchase Return step). New `components/procurement/status-badges.tsx` (same fixed-width badge convention as Receiving/Stock) and `lib/validations/procurement.ts` (zod-free hand-rolled, matching the GRN validation file's style, not its `zod` deviation). - Sidebar: added "Procurement" nav entry between Vendors and Receiving; header title mappings added for all new routes. - Same `[~]` posture as every other module this session: built against the documented+assumed Procurement contract (`docs/11-BACKEND-PHASE1.md` §3), no Procurement backend existed at the time (`Backend/PROGRESS.md` §2 unchanged). **Superseded 2026-07-17** — the Procurement backend exists and these screens now call it; several assumed shapes turned out wrong (see the 2026-07-17 entry). - Verified: `tsc --noEmit` clean (same pre-existing `login/page.tsx` error only); `eslint` clean aside from the same established `set-state-in-effect` pattern used throughout this session (confirmed it also fires on the pre-existing `grn/page.tsx`/`vendors/page.tsx`/`hooks/use-mobile.ts` — not a regression); `npm run build` compiles successfully via Turbopack (same pre-existing login type-check failure blocks the full build, unrelated). All 12 new routes plus the GRN-detail "Create Return" link (including three query-param-prefilled variants) confirmed rendering 200 with no error boundary via SSR against the dev server. ### 2026-07-13 — Master Data screens: Items, UOM, Categories, Reorder settings (frontend-only; no backend changes) - `types/master-data.ts`: `ItemListItem` (the GRN/PO/Requisition/RFQ item-picker subset built in earlier sessions) is now a derived view of a new full `Item` type — SKU/name/description/category/baseUom/defaultVendor/type/trackingMode/taxClass/status plus `reorder: ItemReorderSetting[]` (matches the documented `GET /items/{itemId}` example inline) and `conversions: UomConversion[]` (**deviation**: the doc's example response only shows `reorder`, and conversions are otherwise reachable only via `PUT /items/{itemId}/uom-conversions` with no matching GET — embedding them on the full resource, like the assumed `GET /grns`/`GET /grns/{id}` reads elsewhere in this app, lets the Item detail screen show current conversions before editing). Also added `Category`/`CategoryTreeNode`, `CreateUomRequest`, `CreateCategoryRequest`, and Item create/update/reorder/conversion request types (docs/11 §2.1-2.3). - `lib/api/mock-data.ts`: `mockItems` changed storage shape from `ItemListItem[]` to full `Item[]` (only `mock-data.ts` and `lib/api/items.ts` touched it directly, confirmed by grep, so no other call site broke) — `lib/api/items.ts`'s `list()` now maps down to `ItemListItem`, same "full record → mapped summary" pattern as `mockPurchaseOrders` → `PurchaseOrderSummary`. Added a per-item concurrency-token map (`getItemVersion`/`bumpItemVersion`/`initItemVersion`, same out-of-band ETag pattern as vendors/POs), `mockCategories` seeded with a 2-root/1-child tree matching the category IDs the existing sample items already reference (12 "Fasteners" under 3 "Hardware"; 20 "Power Tools"), and a UOM id allocator. - New API modules: `lib/api/categories.ts` (`list`/`tree`/`create` — `tree()` builds the nested structure client-side from the flat list, since the mock has no separate tree-storage concept). `lib/api/items.ts` grew from list-only (its original GRN-picker scope) to full `get`/`create`/`update`/`updateStatus`/`updateReorder`/`updateUomConversions`; `lib/api/uoms.ts` gained `create`. - Screens: Items (`app/dashboard/products` — **reused the pre-existing "Products" sidebar entry and stub route** rather than adding a new nav item, since it was already wired to an empty placeholder page; list has search + category/tracking-mode/status filters + pagination, `/new` create, `/[id]` detail combining three independently-saved sections in one page — basic info with ETag/If-Match + 412-conflict banner mirroring the Vendor `[id]` page, a Reorder Settings row-editor posting `PUT /items/{itemId}/reorder`, and a UOM Conversions row-editor posting `PUT /items/{itemId}/uom-conversions` — matching how the API groups these as sub-resources of Item rather than separate top-level screens). UOM (`app/dashboard/products/uoms` — flat list + create dialog, same shape as the Warehouses list). Categories (`app/dashboard/products/categories` — indented recursive tree view + create dialog with a parent picker). `lib/validations/master-data.ts` added (hand-rolled, matching the GRN validation file's style, not its `zod` deviation). Header title mappings added for all `/dashboard/products/*` routes. - **Housekeeping:** removed `app/dashboard/vendors/view vendors/` — confirmed byte-for-byte identical to `vendors/[id]/page.tsx` and untracked in git, same IDE-artifact pattern (malformed file-open path) as the garbled GRN duplicate folders removed in the Warehouse Management pass; noted here rather than silently dropped. Left `app/dashboard/receiving/grn/[id]/edit/` alone — it's untracked too but is a distinct, non-duplicate GRN-edit screen, not an artifact. - Same `[~]` posture as every other module this session: built against the documented+assumed Master Data contract (`docs/11-BACKEND-PHASE1.md` §2), no Master Data backend exists (`Backend/PROGRESS.md` §1 unchanged). - Verified: `tsc --noEmit` clean after clearing a stale `.next` type cache that still referenced the just-deleted `view vendors` route (same pre-existing `login/page.tsx` error only remains); `eslint` clean aside from the same established `set-state-in-effect` pattern; `npm run build` compiles successfully via Turbopack (same pre-existing login type-check failure, unrelated). All 5 new/changed routes confirmed rendering 200 with no error boundary against the dev server (one false-alarm 500 during testing traced to an unrelated stale process already bound to port 3000, not this code — retested clean on the actual dev server port). ### 2026-07-15 — Categories/Brands pagination, Item variant builder (Category→Subcategory→Brand→Color/Size), Variant Categories master (frontend-only; no backend changes) - **Pagination:** `categoriesApi.list()`/`brandsApi.list()` (`lib/api/categories.ts`/`lib/api/brands.ts`) changed from returning everything on one page to real `page`/`pageSize`/`q`/`sortOrder` filtering+slicing (page size 5), matching the Vendor list's existing pattern. Both list screens gained debounced search + Previous/Next controls with a "Showing X–Y of Z" caption. **Follow-on fix:** the `new/page.tsx` item-create form and anywhere else fetching the full category/brand list for a `` swatch picker *plus* a required "Color name" text field — picking red alone isn't enough, a name is mandatory too. The pair is encoded as a single string `"|"` in `valuesByCategory` (helpers `encodeColorValue`/`decodeColorValue`/`partLabel` in `new/page.tsx`) so the existing generic value-list plumbing didn't need a parallel data shape; every place that displays or SKU-generates from a color value decodes it back to just the name (the hex only ever drives the swatch dot next to chips and table cells) — so SKUs read `HAR-CRI` (from "Crimson"), never `HAR-EF4`. - Verified: `tsc --noEmit` clean after every step (same pre-existing `login/page.tsx` error only, confirmed unchanged throughout). Each change was driven end-to-end through a headless Playwright session against the dev server and screenshotted — field removal, subcategory always-visible + disabled state, checkbox show/hide of category builders, cartesian flat table with 2+ active categories, inline category creation followed by its builder appearing immediately, and the color picker + name → chip swatch → table swatch → final SKU/item name chain — with `console --errors` clean at every step and at least one full create-and-redirect-to-Items-list confirmed per major change.
