## 🎯 Role baseline

Read-only INTERNAL audit SOLUTION_ERP codebase. Tools: Read, Grep, Glob, Bash + 5 RAG MCP. Output: concise findings <500 words + file:line refs. Skills: `contract-workflow` + `permission-matrix` + `ef-core-migration`.

## 🚫 Split boundary (S39)
- ✅ MINE: internal SQL/EF/grep/reference mirror, sqlcmd schema scan, controller audit, migration diff, count grounding
- ❌ NOT: external docs/CVE/lib → `investigator-api` · write → implementer · test → test-specialist · architecture decision → em main

---

## 📋 Patterns proven (apply confidently)

### Schema scan via sqlcmd
```bash
sqlcmd -S "(localdb)\MSSQLLocalDB" -d SolutionErp_Dev -Q "..."     # runtime API (primary)
sqlcmd -S "(localdb)\MSSQLLocalDB" -d SolutionErp_Design -Q "..."  # ef tooling
ssh vietreport-vps "sqlcmd -S .\SQLEXPRESS -d SolutionErp -U vrapp -P '...' -Q '...'"  # prod
```
Queries: `sys.columns`, `sys.triggers`, `__EFMigrationsHistory`, `COUNT(*)`, `sys.indexes`.
**Gotcha 2 LocalDB distinct** (`feedback_designtime_runtime_db`): `_Dev`=runtime (appsettings.Development), `_Design`=`dotnet ef` default. Prod password fallback `C:\inetpub\solution-erp\api\appsettings.Production.json` khi `$env:PROD_DB_PASSWORD` empty.

### Controller / wire-claim audit
- Grep `\[Route\("api/[a-z]+"\)\]` enumerate controllers · `\[Authorize(Policy = "..."` per-action policy (gotcha #44 silent 403 class-level quá strict)
- Grep `// Mock` / `alert(` / `setEditing(null) // close UI` — wire claim bugs · `IActionResult` vs `ActionResult<T>`

### Smoke verify catalog
Bearer từ `POST api.solutions.com.vn/api/auth/login` → status matrix expected vs actual + file:line evidence.

### Memory cross-reference
30 user-memory tại `C:\Users\pqhuy\.claude\projects\D--...\memory\MEMORY.md` (index). Key: per_chunk_commit · uat_skip_verify · designtime_runtime_db · per_nv_permission_scope · ef_migration_backfill_reorder · workflow_fanout_reliability · canonical_spec_over_broadcast (S79).

### External research → DEFER `investigator-api` (split S39)

## ⚠️ Anti-patterns
❌ Skip MEMORY update · ❌ Vague "seems like/probably" · ❌ Missing file:line · ❌ >500 words · ❌ Scope drift to architecture recommendation (em main decides)

## 🧠 SOLUTION_ERP context essentials (S80 verified — re-ground từ docs/STATUS.md canonical)

- **DB:** Dev `SolutionErp_Dev` · Design `SolutionErp_Design` (distinct) · Prod `.\SQLEXPRESS`/`SolutionErp`/`vrapp` via SSH `vietreport-vps`
- **Migration path:** `src/Backend/SolutionErp.Infrastructure/Persistence/Migrations/*.cs` (⚠️ NOT root `/Migrations/`). **57 mig**, last `AddPeSuggestedPriceNotes`.
- **Counts S80 (canonical docs/STATUS.md):** 57 mig · **88 SQL tables** (count `.ToTable()` ModelSnapshot NOT DbSet) · ~253 endpoints · 68 FE pages · **54 menu keys** (BE `MenuKeys` const) · **354 test** (45 Domain + 309 Infra) · **71 gotchas** (format `### N.`) · 30 user-memory · 6 skills · **11 sub-agents** (all-inherit H8)
- **Tech:** .NET 10 Clean Arch (Api→Application←Domain + Infra) + CQRS MediatR + EF Core 10 + 2 React 19 Vite 8 TS 6 (fe-admin :8082 + fe-user :8080) + SQL Server + Gitea CI + IIS
- **Prod:** api/admin/eoffice.solutions.com.vn · Gitea `git.baocaogiaoduc.vn/vietreport-admin/solution-erp` (Actions API `/api/v1/repos/.../actions/tasks` NOT `/runs` 404, cache stale ~2min gotcha #46 — cross-check VPS mtime). Bundle live admin `CsJetgZH`/user `BVS0ApIm` (Run #330).
- **Auth:** `admin@solutions.com.vn/Admin@123456` (full) / `nv.test@solutions.com.vn/TestUser@123456` (Drafter). Response `accessToken`+`refreshToken`+`user`. Password ≥12 chars.

## 🔄 Active workflow schemas (V1 + V2 coexist post-S17)

- **V1 Mig 21 flat** — `WorkflowDefinition` pin PE/Contract cũ. Match Dept+PositionLevel.
- **V2 Mig 22-31** — `ApprovalWorkflow` pin PE/Contract mới, match `ApproverUserId` 1-1 OR-of-N cùng Cấp. Steps (Phòng) > Levels (Cấp). PE + Contract đã wire V2 (Mig 32+33 S29). Proposal V2 (Mig 38). WorkflowApps skeleton (Mig 39).
  - Mig 25 IsUserSelectable · Mig 26 PE LevelOpinions UPSERT · Mig 29 Allow* per-NV · Mig 30 F4 AllowApproverEditBudget · Mig 31 SkipToFinal→ApproverLevel · Mig 53 cờ-gấp+CeoApprovalThreshold · Mig 54 giá-đề-xuất PRO/CCM+giá-chốt · Mig 56 ProInitial/ProAdjust · Mig 57 ghi-chú-giá.
- **State machine PE 5 trạng thái:** Nháp / Đã gửi duyệt / **Trả lại (TraLai=98)** / Từ chối (REMOVED-S60 hard-guard) / Đã duyệt
- **Mode Trả lại 4 option per-Level:** OneLevel (lùi 1 Cấp) / OneStep (lùi Bước trước) / Assignee (pick NV đã ký) / Drafter (Phase=TraLai). 3 mode đầu giữ ChoDuyet lùi pointer. Admin bypass `level.Allow*`.

## 📅 Recent activity (compressed — full verbatim → `archive/2026-06.md` via `archive/_INDEX.md`)

- **2026-06-25 PE FROZEN patchwork audit AREA-6 (FE consumers BOTH apps — multi-winner + mirror-drift + dead-code + #70):** ⭐ Post-Mig58 multi-winner (`isWinner` bool) NOW implemented (supersedes 06-24 "SINGLE" recon). **All 6 PE components + 3 PE pages SHA-IDENTICAL fe-admin↔fe-user** (PeDetailTabs/PeHeaderForm/PeUrgentChips/PeListPanel/PeWorkspaceCreateView/PeWorkflowPanel). type files DIFFER but ONLY badge-tint (-700→-800 ink) + comments (intentional per-app UX, struct fields identical incl ccmBudgetPeriodAmount/isWinner/8 Allow flags). **RESIDUAL single-winner BUG (low):** `PeListPanel.tsx:168` renders `p.selectedSupplierName` (list-card winner label) → BLANK when ≥2 joint winners (BE list-DTO `PurchaseEvaluationFeatures.cs:615,706` projects from `SelectedSupplierId` which BE sets null when count≠1 `PurchaseEvaluationDetailFeatures.cs:431`). List DTO has NO isWinner/winner-list field; detail-view multi-winner correct everywhere (8 detail consumers all converted: computeGiaChaoThau:78, missingForApproval:195, submitChecklist:229, ThongTinChonThau:1949/1970, Section-B row4:1578, CreateContractDialog:2171 fallback `||selectedSupplierName`, HangMucCard toggle:2560). **#70 stale-echo ASYMMETRY:** budget Section-B CCM-period editor gates `ccmPeriodMut.isPending||peFetching` (`PeDetailTabs.tsx:1563`) but PRO sibling row3/row8 `adjustMut` gates `.isPending` ONLY (`:1548,:1649`, NO peFetching) — rapid PRO row3→row8 absolute-set pair can echo stale ev.* pre-refetch (same #70 class CCM guards). 3 peFetching sites exist (945/1268/1736). **Stale comment** PeDetailTabs:2507 references `AddItemDialog` "giữ(dead)" but function DELETED (grep 0 def) — misleading comment only, not dead code. PeWorkflowsPage admin-only = by-design (workflow config not mirrored). → _INDEX.
- **2026-06-25 PE FROZEN patchwork audit AREA-2 (budget matrix + Section B 3-col, Mig 56/59):** ⭐ **BAND-AID CONFIRMED** `SetPeCcmBudgetPeriodCommand+Validator+Handler` (`PeSuggestedPriceFeatures.cs:153-199`) is a BUDGET setter (writes `pe.CcmBudgetPeriodAmount`) MISPLACED in a price-feature file; SHOULD live in `PeWorkItemBudgetFeatures.cs` (where UpdatePeBudgetPro/Ccm sit). Test+comments already self-flag (PeCcmBudgetPeriodSetterAuthzTests.cs:14). ⚠️ **Role-gate ASYMMETRY (intentional, NOT a bug — but inconsistent surface):** CCM budget setters = flat role-gate (CostControl|Admin fail-closed): UpdatePeBudgetCcm `PeWorkItemBudgetFeatures.cs:160-165` + SetPeCcmBudgetPeriod `PeSuggestedPriceFeatures.cs:176-181`. BUT the PRO sibling `/budget-adjust`→`AdjustPurchaseEvaluationBudgetCommandHandler` `PurchaseEvaluationFeatures.cs:349-394` = **phase/drafter/workflow-slot gate** (Drafter when Nháp/TraLai; Approver+AllowApproverEditBudget F4 when ChoDuyet) NOT role-PRO. So "PRO col" & "CCM col" of same Section-B row 3 have DIFFERENT authz models (PRO=drafter-flow on `pe.BudgetPeriodAmount`; CCM=role-flow on `pe.CcmBudgetPeriodAmount`). Both per-PE fields (NOT PeWorkItemBudget per-pair — that's the matrix rows Initial/Adjustment). Section-B **"Dự án" col = intentional FE-only "—"** hardcoded (`PeDetailTabs.tsx:1520,1542,1596,1606`; Domain `PeWorkItemBudget.cs:19` "chưa wire BE — sau mới có người dự án nhập") — documented, NOT a stub-bug. Controller class-level `[Authorize]` only (`PurchaseEvaluationsController.cs:15`) → handler gates ARE the boundary. Tests solid (PeWorkItemBudgetTests 30+ cases, PeCcmBudgetPeriodSetterAuthzTests 7). → _INDEX.

- **2026-06-24 PE 3-change recon (Lưu Trần/anh Kiệt CCM — multi-winner + budget=0-valid + per-step terminal):** ⭐ (A1 winner) cardinality=**SINGLE** scalar `PE.SelectedSupplierId Guid?` (`PurchaseEvaluation.cs:28`); cmd `SelectPurchaseEvaluationWinnerCommand(PEId,Guid?)` `PurchaseEvaluationDetailFeatures.cs:392` handler `:398-423` (null=clear S85-C5); ctrl `/select-winner` `PurchaseEvaluationsController.cs:167-172`. winnerQuoteTotal=**DERIVED** SUM `Quote.ThanhTien WHERE SupplierId==Selected` 3 sites: read `PurchaseEvaluationFeatures.cs:1089` + submit-guard `PurchaseEvaluationWorkflowService.cs:191` + ccm-delegate `:868`. ⚠️ Quote ALREADY has `IsSelected bool` (`PurchaseEvaluationQuote.cs:15` per-item winner, UNUSED by total). Multi-winner = NEW junction OR reuse IsSelected + change predicate `==Selected`→`IN selectedSet`. FE single `<Select>` `PeDetailTabs.tsx:961-991` (NccSelectorRow). (A2 budget=0) BLOCKED 2 layers: validator `.GreaterThan(0).When(HasValue)` create `:55` + UpdateDraft `:233` + budget-adjust `:339`; submit-guard `effectiveBudget<=0`→missing `PurchaseEvaluationWorkflowService.cs:213-216` (effective=`BudgetPeriodAmount??ProInitialAmount` S85-D3). FE `effBudget<=0` `PeDetailTabs.tsx:211,237` canSubmit `:242`. To allow 0: relax `>0`→`>=0` validator + submit `<0` + FE. winnerQuoteTotal-gate SEPARATE `:194`. (A3 terminal) `ApprovalWorkflowLevel` already has 6 per-slot bool flags (`ApprovalWorkflow.cs:104-131`: AllowReturnOneLevel/OneStep/ToAssignee/ToDrafter/EditDetails/EditBudget/**SkipToFinal**); `CeoApprovalThreshold decimal?` on WORKFLOW `:43`. Finalize branches `ApproveV2Async`: terminal `nextIdx>=steps.Count` `:905-916` + ccm-delegate opt-in `:854-891` + skipToFinal `:803-844`. "Approve-ends-here" = NEW per-Level bool mirror SkipToFinal but set Phase=DaDuyet (like ccm-delegate but no threshold). Designer FE = `fe-admin/ApprovalWorkflowsV2Page.tsx`. **schema-decision forks→em-main:** (1) multi-winner storage: reuse Quote.IsSelected vs new PE↔Supplier winner-junction (2) budget=0 vs budget-null distinction post-relax (3) terminal flag scope per-Level vs per-Step + interaction w/ CeoApprovalThreshold (both finalize → ordering). → _INDEX.

- **2026-06-25 PE AREA-4 UpdatePeDraft edit-preserve audit (gotcha #73-class hunt, FROZEN Mig 59):** ⭐ **LATENT #73-CLASS BUG FOUND:** `UpdatePeDraftHandler` absolute-sets `entity.HoSoLink = request.HoSoLink` (`PurchaseEvaluationFeatures.cs:280`) BUT `PeHeaderForm.tsx` PUT payload (admin+user `:112-120`) OMITS hoSoLink → editing header CLEARS HoSoLink (Mig 52) to null. HoSoLink set separately in `PeDetailTabs.tsx:2012-2020` HoSoLinkRow (re-sends all absolute fields but only IT edits link). Two PUT call-sites to SAME /purchase-evaluations/{id} endpoint are mutually destructive. PeHeaderForm reachable as EDIT (`PurchaseEvaluationCreatePage.tsx:13,26` editId from URL `?id=`, deep-link "Sửa header"). Field table: TenGoiThau/DiaDiem/MoTa/PaymentTerms absolute-set BUT PeHeaderForm re-sends all (safe); HoSoLink absolute-set + OMITTED (BUG); ApprovalWorkflowId/Budget/ExpectedRemaining/WorkItemId all null-safe `if(x is not null)` `:285-297` (S85 fix). ExpectedRemaining absolute-set in budget-adjust `:423-424` (FE sends both, OK). Require-workflow NOT duplicated: CREATE-validator `:48` + submit-guard `PurchaseEvaluationWorkflowService.cs:237` = different lifecycle (coherent defense-in-depth); UPDATE-validator correctly omits. Tests SOLID: PeUpdateDraftWorkflowPreserveTests (3 null-safe cases incl ApprovalWorkflowId+Budget) + PeSubmitGuardAndBypassTests (14) + PurchaseEvaluationDraftGuardTests (8). NO HoSoLink-preserve test (test-gap for the bug). → _INDEX.
- **2026-06-25 PE AREA-3 finalize/price audit (FROZEN Mig 59 Run#346 — patchwork hunt):** ⭐ TWO finalize mechanisms COEXIST + BOTH LIVE (NOT dead): (1) `AllowApproverFinalize` per-Level AUTO config (Mig 58) `PurchaseEvaluationWorkflowService.cs:861-877` + (2) `finalizeByCcmDelegation` OPT-IN param threshold-gated (Mig 54) `:879-915`. AUTO runs FIRST + returns → if both eligible, OPT-IN flag silently ignored (coherent, no double). `finalizeByCcmDelegation` FULLY wired E2E (ctrl `:141`+`:351` · Feature `:474,:526` · IPe…Service:32 · FE both `PeWorkflowPanel.tsx:184,584` ô-tích) — NOT orphan. ALL 3 DaDuyet paths bind giá chốt via `ApplyApprovedPriceOnFinalize` (private static `:956-971`, allow-list `{Ncc,ProMin,ProMax,Ccm}` `:955`): terminal `:933` + AllowApproverFinalize `:863` + ccm-delegate `:901`. isSystem-exempt branch (`:961-964`) = DEAD via public ApproveV2Async (needs decision=AutoApprove but APPROVE-STEP gates Approve; PE has NO SLA-job — only Contract) — tested-only-via-reflection (PeApprovedPriceFinalizeTests:238-295, header DISCLOSES "defensive/dead"). **MISPLACED-CODE CONFIRMED (known band-aid):** `SetPeCcmBudgetPeriodCommand` (Mig 59 Section-B BUDGET setter) lives in `PeSuggestedPriceFeatures.cs:153-199` (a SUGGESTED-PRICE file) — wrong file, own header admits Section-B. Has test `PeCcmBudgetPeriodSetterAuthzTests.cs` (NOT test-gap). DTO `currentLevelOptions` per-NV-discriminated `PurchaseEvaluationFeatures.cs:950-963` = same source as service `matchingLevel` (coherent). 4 finalize test files all present + green-design. → _INDEX.
- **2026-06-25 PE AREA-5 urgent/notify/TZ audit (FROZEN Mig 59 — gotcha #72):** ⭐ (a-TZ) `UtcDateTimeJsonConverter` registered ONLY on `AddControllers().AddJsonOptions` `Program.cs:33-34` — covers REST. ⚠️ **SignalR push BYPASSES it** (`AddSignalR()` no `.AddJsonProtocol`, separate STJ): `NotificationPushInterceptor.cs:77` pushes `createdAt=n.CreatedAt` over `SendAsync`. BENIGN at runtime: `n.CreatedAt=clock.UtcNow`=Kind.Utc (DateTimeService.cs:7) → default STJ writes 'Z' for Utc-kind, FE `new Date(iso)` NotificationBell.tsx:23 OK. Latent: any future SignalR push of an EF-READ (Unspecified) DateTime would skew. NOT a bug now, inconsistency-low. Converter handles DateTime? auto (non-null) — no double-convert. (b-authz) Urgent SET/UNSET branches `PurchaseEvaluationUrgentFeatures.cs:54-73` SYMMETRIC + fail-CLOSED both (`if(!allowed)throw` BEFORE mutate); 14 tests `PeUrgentToggleAuthzTests` cover plain/TP/Admin/drafter×set/unset. No fail-open. Controller class-`[Authorize]` only `:91` → handler IS boundary. (c-notify) Drafter excluded 2 sites: advance `:1138` (`!=DrafterUserId`) + terminal-result KEPT `:1085`; tests `PeApproverNotifyExcludesDrafterTests` RED-on-remove. ⚠️ **POSSIBLE double-notify-then-skip:** submit `:252` LogTransition notifies Cấp-1 approvers (excl drafter+actor) THEN `:260` ApplyDrafterBypass advances pointer + `:650/660` re-notifies new level — if drafter=Cấp1 w/ co-approver, co-approver pinged for a level immediately bypassed. Low-sev (extra ping, not wrong recipient); no de-dup across the 2 LogTransition calls. → _INDEX.
