Bug: a multi-project quote accepted for «تست ۱» only also appeared under «تست ۲»'s پذیرفته شده column, because both the Projects page and /projects/{id}/stats classified quotes by their GLOBAL status over any project link.
Rule now: a quote counts as accepted/arrived for a project ONLY if at least one non-rejected line item's decision targets that project (item_decisions.project_id). A quote merely linked as a candidate — including one accepted for a different project — is categorized exclusively under پیشنهاد شده for that project. Legacy quotes without any decision targets keep the old global-status classification.
Backend: project_stats membership now spans all link kinds (legacy mirror, quote_projects, line_item_projects, decision targets) with the per-project decision-based bucketing above; bucket VALUES follow the same isolation (accepted/arrived value counts only items targeting the project; candidate items of a still-proposal quote stay in the offered bucket); the raw path string is normalized to UUID for the Python-side comparisons. /quotes?project_id=… now matches any relevant link kind instead of only the legacy mirror column.
Frontend: ProjectsPage gains acceptedForProject/hasTargets helpers; the three columns (پیشنهاد شده / پذیرفته شده / رسیده) and their value chips use per-project items (target-project items first, then candidates), so totals no longer leak other projects' items.
Verified end-to-end (2 projects × 1 quote × 2 items, accept item-1 for P1 only): P1 accepted=1 then arrived=1 after the PM receipt; P2 stays offered=1 / accepted=0 / arrived=0 at every step; /quotes?project_id=P2 still lists the quote. All fixture data removed; 7/7 checks pass. python compile + api/frontend builds clean.
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).
