Materials are now global and category-free. The category lives only on the supplier (suppliers.category_id); every category-facing query goes through the supplier edge instead of the material row.
Schema (migration.sql + init_db DDL):
- drop the materials.category_id column, its FK, and the v2.5 first-link-wins automation (fn_derive_material_category + trg_supplier_materials_derive_category) — the DDL runs idempotently at API startup
Backend:
- GET /materials?category_id=… now filters via EXISTS(supplier_materials ⋈ suppliers.category_id)
- quote category filters (quotes list) use the quote's supplier category
- /pm/on-the-way derives the display category from the supplier of the quote
- supplier_materials links no longer derive/return a material category
- expand_service: material expand=category resolves to null (kept for contract compatibility)
- material create/update no longer validates or stores category_id; seed.py aligned
Frontend:
- material creation no longer sends category_id
- formatMaterialTitle reworked to a strict order with « . » separator: [Brand] . [Material] . [Spec 1] . [Spec 2], brand deduped when the stored name already starts with it; specs separator switched from « · » to « . »
Validated: python compile, api + frontend image builds (tsc + vite) clean; branch cut from the tip of prod_v4 (= origin/production, 5a9ef40 — the team's merge made them identical).
Wizard:
- failed saves now route to the exact step+field: a new data-field attribute on every required section (supplier_id, line_items, termsheets, project, quote_date, expiry_date, notes, proforma) plus resolveErrorTarget() that maps ApiError.field / message keywords (supplier, line item/material/unit/quantity, termsheet/schedule/milestone, project, dates, notes, file) to the offending step — the «رفع خطا» toast action scrolls/focuses the right control instead of guessing
- material records are no longer created on the fly while typing (rememberMaterial no longer fires addMaterial per blur); materials/specs/units are written once during the final save, avoiding half-created catalog rows
Accept flow:
- quote_service no longer rewrites LineItemProjects on accept — those candidate-project rows stay 100% untouched and only item_decisions.project_id is written, matching the per-item target-project model and the UI payload (item_projects: [])
Dates/time:
- JalaliDatePicker: hour/minute are now editable text fields (Persian digits, clamping, 3-digit retype handling) with a controlled useEffect that only rewrites the inputs when the numeric value actually changes — no more wiping in-progress typing; date-only detection tightened to a full YYYY-MM-DD match so datetime strings are not misread
Also: /api validation logging (RequestValidationError) now includes the path and error list for faster diagnosis.
Verified: api + frontend image builds (python, tsc, vite) clean on top of origin/production (incl. the team's mobile layout merges).
Quotes that already have warehouse receipts can no longer be edited or rolled back:
- backend: quote_has_receipts() guard — replace_quote_children and every backward status transition now return 409 with «این پیشنهاد بهدلیل ثبت رسید در انبار، غیرقابل ویرایش یا بازگشت است.»
- reopening to «offered» additionally clears item_decisions.project_id (the purchased-project link belongs to acceptance, not to a reopened offer)
- frontend EditModal: hasReceipts locks the whole form — disabled inputs and date pickers (JalaliDatePicker/NumberInput/MilestoneRow/MultiSelectCombobox gained disabled support), add/remove controls for items, termsheets and milestones hidden, status change blocked, amber warning banner; quote deletion now goes through a confirmation dialog (useDeleteQuote)
- date-only semantics: JalaliDatePicker keeps/emits YYYY-MM-DD when withTime=false (typing, «امروز», day selection) and toDateOnly no longer mangles pure date strings
Per-item target project (candidate projects stay intact):
- expand_service exposes the decision target project (decision.project + line_item.target_project)
- the accept payload derives item_decisions.project_id from that target project and sends item_projects: [] so line_item_projects keeps the original candidates untouched
- AcceptModal/EditModal select the target project per line item
Material titles:
- quoteUtils.formatMaterialTitle() composes one normalized, deduplicated «name + brand + specs» title, replacing materialLabel/materialSpecs/specsLabel usage across dashboard cards, quote detail and the modals
Verified: python compile + api/frontend image builds (tsc + vite) clean.
New shared materialLabel() renders the global materials.name with brand/specs
appended only when not already part of the name (deduped; «؟» fallback kept).
Replaces the category-first composer in five places: supplier card badges
(CategoryPage), dashboard item lines (QuoteCard), ledger items summary,
project rows and purchase history. Also fixes the stale Units subtitle
«ضریب تبدیل همان دسته» → «ضریب تبدیل متریال» (category model kept).
