📋 Patterns proven (cross-session)

Pattern: Smoke verify catalog SOLUTION_ERP

• Bearer auth từ https://api.solutions.com.vn/api/auth/login (POST email + password)
• Status code matrix expected vs actual + JSON output + MD audit
• Test credentials: admin@solutions.com.vn / Admin@123456 (full) OR nv.test@solutions.com.vn / TestUser@123456 (Drafter UAT scope)

Pattern: Schema scan via sqlcmd

# LocalDB Dev (runtime — primary)
sqlcmd -S "(localdb)\MSSQLLocalDB" -d SolutionErp_Dev -Q "..."

# LocalDB Design (ef tooling)
sqlcmd -S "(localdb)\MSSQLLocalDB" -d SolutionErp_Design -Q "..."

# Production (qua SSH vietreport-vps)
ssh vietreport-vps "sqlcmd -S .\SQLEXPRESS -d SolutionErp -U vrapp -P '...' -Q '...'"

Common queries: sys.columns, sys.triggers, __EFMigrationsHistory, COUNT(*), sys.indexes.

Gotcha: 2 LocalDB distinct (memory feedback_designtime_runtime_db):

• _Dev — runtime API (appsettings.Development.json ConnectionStrings:Default)
• _Design — dotnet ef migrations add/update default target
• Use --connection "Server=(localdb)\MSSQLLocalDB;Database=SolutionErp_Dev;..." override khi cần Dev specifically.

Pattern: Controller audit

• Grep \[Route\("api/[a-z]+"\)\] enumerate ~30+ controllers
• Grep \[Authorize(Policy = "..." audit per-action policy (gotcha #44 silent 403 class-level quá strict)
• Grep IActionResult vs ActionResult<T> — typed return preferred
• Grep // Mock / alert( / setEditing(null) // close UI — wire claim bugs

Pattern: Memory cross-reference

• feedback_ef_migration_backfill_reorder.md — ADD→BACKFILL SQL→DROP manual reorder (S21 t5 Mig 29)
• feedback_per_nv_permission_scope.md — Multi-role flag split scope per role (Approver Level vs Drafter User), S21 t4→t5 refactor
• reference_session_prompts.md — canonical session start template

Pattern: External research priority sources

📅 Recent activity (last 10 FIFO)

• 2026-05-15 (S24 t1 spawn Pre-A — Plan AA User Workflow Matrix view + sidebar widen): 5Q audit. Q1 endpoint: ApprovalWorkflowsV2Controller.cs:16-19 đã class-level [Authorize] bare từ S18 2026-05-08 (gotcha #44 fixed permanent), per-method admin Workflows.Create. Handler GetAwAdminOverviewQuery KHÔNG có IsUserSelectable filter — cần ADD param + Where conditional. Q2 menu seed: DbInitializer.cs:1429-1437 peOrder global increment (Group=1, leaves 2/3/4 cycle per type). Permission seed line 1541-1547 cho 7 role (Drafter/DeptManager/Procurement/CostControl/ProjectManager/Director/AuthorizedSigner). Accounting NOT trong list — admin manual grant nếu cần. Q3 Admin Designer: ApprovalWorkflowsV2Page.tsx 975 lines, AwLevelDto 13 fields (7 Allow*), VI labels line 892-948 ("Trả về 1 Cấp trước"/"Trả về 1 Bước trước"/"Trả về Người chỉ định"/"Trả về Drafter (mặc định)"/"Cho phép chỉnh sửa Section 2 (Hạng mục/NCC/Báo giá) lúc đang duyệt"/"Cho phép chỉnh sửa Section ngân sách lúc đang duyệt"/"Cho phép duyệt thẳng Cấp cuối khi đang duyệt"). KHÔNG có usePermission/PermissionGuard wrap (class-level [Authorize] route guard sufficient). Q4 sidebar widen: fe-user Layout.tsx:325 + fe-admin Layout.tsx:218 w-60 xl:w-72 (240/288px). PE Workspace 2-panel [260px_1fr] xl:[320px_1fr] (NOT 3-panel như memory feedback_responsive_laptop_breakpoint stale claim). After widen w-72 xl:w-80 (288/320px) SAFE (sidebar 288 + main 992 → workspace 260+732 fit @ 1280px). w-80 xl:w-96 THRESHOLD RISKY (sát 700px remaining). Q5 ApplicableType enum ApprovalWorkflow.cs:45-50 {DuyetNcc=1, DuyetNccPhuongAn=2, Contract=3}. Surprises: (1) memory responsive breakpoint stale "3-panel" → cần update sau Plan AA. (2) Order strategy "Luồng duyệt" Order=2 first → shift existing leaves +1 → cần DbInitializer UPDATE Order existing (KHÔNG chỉ INSERT-if-not-exists). (3) Contract=3 chưa wire FE (chỉ DuyetNcc + DuyetNccPhuongAn). Recommendation: Proceed Plan AA — chỉ ADD param filter + 1 menu key + page mới + sidebar widen. Token cost ~32k.
• 2026-05-15 (S24 t1-t4 post-spawn, em main solo 4 polish chunks — Plan AA wrap): 7 commits total a1a910f..ee0902a: BE+Layout (ee776d5) + FE Page (c667802) + Docs (ac2c859) + 4 polish iter UAT (da218f1 px-2 + 4d60598 v1 panel-per-NV + fbbd361 v2 table rowSpan + ee0902a sidebar label wrap). Pattern reusable: inline-block icon + inline text + absolute ChevronDown cho hanging-indent reverse wrap (label dài về đầu hàng). Mirror admin Designer style cho user view read-only. Sidebar widen tradeoff: w-72 xl:w-80 + remove truncate FAIL fit 44+ chars label custom Mig 27 — cần combine với text-[12px] + leading-snug + restructure flex → block + inline. Sole truncate removal không đủ — phải full layout restructure NavLink. Memory drift confirmed: feedback_responsive_laptop_breakpoint.md claim "PE Workspace 3-panel" → S24 verify ACTUAL 2-panel (260+1fr only, KHÔNG có panel thứ 3). Cross-ref update needed memory user-level (admin trigger curate sau). Plan AA color palette success: STEP_PALETTE 5 màu (blue/purple/emerald/amber/pink) + LEVEL_PALETTE 5 màu (violet/sky/teal/orange/rose) — Tailwind JIT yêu cầu full class strings array, KHÔNG dynamic interpolation (bg-${color}-100 FAIL — class purged). Reusable cross-project cho menu hierarchy color coding (step parent + level child distinct palette). Final layout v2 table rowSpan: Step column merge per-Phòng + Level column rowSpan per-Cấp + NV column 1-row-per-approver, đẹp hơn v1 panel-per-NV stacked. Token cost iteration negligible (em main solo, no spawn).

Admin ĐÃ tick 7 Allow*=TRUE riêng cho slot NV Test UAT V2. Nhưng FE dialog Duyệt KHÔNG hiện checkbox SkipToFinal + Trả lại 4 mode + Edit. Verdict: HYPOTHESIS B — BE handler picks wrong slot row. Evidence: (1) PurchaseEvaluationFeatures.cs:765 var curLevel = curStep?.Levels.FirstOrDefault(l => l.Order == curLevelOrder); — match FIRST row có Level.Order == curLevelOrder, NOT actor's row. Post-Mig 29 refactor, Level.Order trùng nhau cho mọi NV cùng Cấp (4 row có Order=1 ở Step 2). EF returns Trần Xuân Lưu trước (PK order) → FirstOrDefault lấy row đó (all-false except Drafter=true). (2) API curl admin token + nv.test token return CÙNG currentLevelOptions={ allowReturnOneLevel=false, OneStep=false, Assignee=false, Drafter=true, EditDetails=false, EditBudget=false, SkipToFinal=false } — handler currentUser-agnostic confirm.

Fix BE 1 dòng: var curLevel = curStep?.Levels.FirstOrDefault(l => l.Order == curLevelOrder && l.ApproverUserId == currentUser.UserId); (admin bypass: fallback ?? curStep?.Levels.FirstOrDefault(l => l.Order == curLevelOrder) để admin xem detail không lỗi).

Lesson: drop migration cần verify entity scope toàn bộ (Contract liên đới — không chỉ PE). (3) Identity password policy ≥12 chars — seed 20 user FAIL 400 với "User@123456" (11 chars), TestUser@2026 (13 chars) pass. (4) Identity rename atomic 4 fields confirm gotcha #38: Email + NormalizedEmail + UserName + NormalizedUserName + FullName; sqlcmd cần SET QUOTED_IDENTIFIER ON cho filtered unique index. (5) API login response field name accessToken + refreshToken + user — KHÔNG có field token (correct prior Bash example trong spec dùng .token sẽ fail). (6) PS 5.1 ASCII-only script discipline reinforced gotcha #30: seed-test-users-prod.ps1 viết Vietnamese names without diacritics tránh parser error. Recommend bro add 1 memory entry "Admin opt-in flag pattern proven 2×" cumulative Mig 29 + Mig 30.
• 2026-05-13 (S21 t3-t5, no spawn): Em main solo 3 turns (bug fix gotcha #45 + F1+F2+F3 workflow-level Mig 28 + refactor per-NV Mig 29). Implementer REFUSE per cross-stack reasoning chain rule. Investigator KHÔNG spawn — em main đã có context cumulative S20 t12 setup + active dev throughout. No findings to flush. Cumulative state update: 84 test, 29 mig, 45 gotcha, 19 memory entries (+2 S21 t5 pending), 6 skills unchanged. Pattern reusable saved cho future spawn: per-NV permission scope split + EF migration ADD→BACKFILL→DROP reorder.
• 2026-05-11 (setup): Investigator agent initialized. Baseline knowledge load complete (44 gotchas + 14 memory entries + 6 skills + 27 mig + 81 test pass cumulative). No investigations performed yet. Awaiting first SendMessage from em main.
