Session 22 — 2026-05-13 18:00 — Plan D + C + E (Plan F ABORTED)

Dev: Claude Opus 4.7 1M Max (em main solo — Implementer REFUSE cross-stack reasoning chain) Duration: ~2.5h (start session context load + 4 plan execute + finalize) Base commit: 3d725c4 (S21 chốt cuối) Commits this session: 60efeed (D) → dbda37e (C task 4) → 215b1e0 (C task 1-3) → f149661 (E) → this (Docs)

Trigger

Bro yêu cầu kick off 4 plan đồng thời: Plan C + D + E + F (test backlog + F2 toggle UI + phân quyền strict V2 + drop legacy V1).

Em hỏi clarify 3 câu trước khi kick off:

• Q1 thứ tự: D→C→E→F (an toàn → risk dần)
• Q2 Plan F destructive: drop luôn không backup (UAT chấp nhận risk) — nhưng em vẫn pre-flight check phiếu V2 không pin V1
• Q3 Plan E scope: toàn bộ List + Inbox + Detail

Plan D — User Management F2 toggle UI (60efeed)

Wire FE UI cho AllowDrafterSkipToFinal (BE column từ Mig 29 đã sẵn).

BE — UserFeatures.cs + UsersController.cs

• UserDto +AllowDrafterSkipToFinal bool (cuối record)
• ListUsersQueryHandler + GetUserQueryHandler populate field
• SetUserAllowDrafterSkipToFinalCommand + Handler mới mirror SetUserBypassReviewCommand pattern
• UsersController.cs +endpoint PATCH /api/users/{id}/allow-skip-final body {allowDrafterSkipToFinal:bool} Policy=Users.Update

FE Admin — users.ts + UsersPage.tsx

• User type +allowDrafterSkipToFinal: boolean
• Column "Skip cuối" với FastForward icon violet badge
• Action button toggle (allowSkipMut) — title đổi theo trạng thái
• fe-user KHÔNG mirror (UsersPage admin-only theo PROJECT-MAP)

Verify

• dotnet build SolutionErp.slnx — 0 err, 2 warn pre-existing DocxRenderer
• npm run build fe-admin — pass 638ms

Plan C task 4 — Regression test #44 silent 403 (dbda37e)

Test-before backlog HIGH §7 priority (S18 nợ — Drafter nv.test Workspace dropdown empty silent).

File mới tests/.../Api/AuthorizePolicyRegressionTests.cs

5 reflection-based tests verify ApprovalWorkflowsV2Controller policy split:

1. Class-level [Authorize] only, NO Policy
2. GET Overview inherits class-level (no action-level Policy)
3. POST Create require Policy="Workflows.Create"
4. DELETE require Policy="Workflows.Create"
5. PATCH user-selectable require Policy="Workflows.Create"

Pattern reusable cho future Authorize regression — catch nếu ai add Policy lên class-level hoặc GET action mà không qua UAT silent 403 reproduce.

Add ProjectReference SolutionErp.Api → SolutionErp.Infrastructure.Tests cho reflection access Controller types.

Verify

• 84 → 89 PASS (+5 regression #44)

Plan C task 1-3 — Service test catch-up S21 t4-t5 (215b1e0)

14 test cover 3 helper sửa lớn S21 t4-t5.

Services/PurchaseEvaluationWorkflowServiceReturnModeTests.cs (7 test)

Task 1 — ApplyReturnModeAsync per-NV (Mig 29):

• Drafter mode allowed by Level → Phase=TraLai, clear pointer
• Drafter mode denied by Level (non-admin) → ConflictException
• OneLevel allowed by Level → curLevel 2 → 1 (peer review trong Step)
• OneLevel denied by Level + Admin bypass → succeeds (admin override)

Task 2 — skipToFinal per-Drafter (Mig 29):

• Drafter AllowDrafterSkipToFinal=true → set pointer cuối Step + cuối Level
• Drafter AllowDrafterSkipToFinal=false non-admin → ConflictException
• Admin bypass user flag → succeeds

Application/PurchaseEvaluationDraftGuardTests.cs (7 test)

Task 3 — EnsureEditableForDetailsAsync F3 gating:

• DraftScope DangSoanThao + any caller → return PE
• DraftScope TraLai + any caller → return PE
• ApproverScope ChoDuyet + flag on + actor match → return PE
• ApproverScope ChoDuyet + flag off (non-admin) → ConflictException
• ApproverScope ChoDuyet + flag on + actor mismatch → ForbiddenException
• AdminBypass ChoDuyet + flag off → return PE
• DaDuyet terminal phase + any caller (kể cả admin) → ConflictException

Pattern infra

• Helper SeedWorkflowAsync tạo 1 Bước (Step) × 2 Cấp (Levels) với mọi Allow* default false (admin opt-in pattern Mig 29).
• Helper SeedApproversAsync create approver users qua IdentityFixture.CreateUserAsync để satisfy FK ApproverUserId constraint.
• DepartmentId = null trên Step để skip FK Department.
• FakeCurrentUser implement ICurrentUser minimal cho Guard tests.
• InternalsVisibleTo("SolutionErp.Infrastructure.Tests") thêm vào SolutionErp.Application.csproj để test access internal static class PurchaseEvaluationDraftGuard.

Finding (sub-optimal nhưng không scope catch-up)

Service skipToFinal flow mutate evaluation.Phase = ChoDuyet TRƯỚC validate user flag. Throw chặn SaveChanges nên DB không persist nhưng in-memory entity dirty. Test phải relax secondary assertion pe.Phase → assert pointer chưa init thay vì rollback. Note trong test comment cho future refactor.

Verify

• 89 → 103 PASS (+14: 7 ReturnMode + 7 Guard)

Plan E — Phân quyền strict V2 (f149661)

Thắt chặt PE V2 List + Detail từ UAT loose sang strict actor.UserId scope (Inbox đã strict từ S17 — KHÔNG đụng).

Change 1: ListPurchaseEvaluationsQueryHandler

Trước (UAT loose):

q = q.Where(x =>
    x.e.DrafterUserId == userId
    || eligiblePhases.Contains(x.e.Phase)
    || x.e.ApprovalWorkflowId != null);   // V2 loose UAT

Sau (strict):

var userApprovalWfIds = await db.ApprovalWorkflowLevels.AsNoTracking()
    .Where(l => l.ApproverUserId == userId.Value)
    .Select(l => l.Step!.ApprovalWorkflowId)
    .Distinct()
    .ToListAsync(ct);
q = q.Where(x =>
    x.e.DrafterUserId == userId
    || eligiblePhases.Contains(x.e.Phase)
    || (x.e.ApprovalWorkflowId != null && userApprovalWfIds.Contains(x.e.ApprovalWorkflowId.Value)));

Change 2: GetPurchaseEvaluationQueryHandler

Trước: var isPinnedV2 = e.ApprovalWorkflowId is not null (loose).

Sau:

var isV2Approver = false;
if (e.ApprovalWorkflowId is Guid awIdForCheck && currentUser.UserId is Guid uidForCheck)
{
    isV2Approver = await db.ApprovalWorkflowLevels.AsNoTracking()
        .AnyAsync(l => l.Step!.ApprovalWorkflowId == awIdForCheck
            && l.ApproverUserId == uidForCheck, ct);
}
if (!isDrafter && !eligiblePhases.Contains(e.Phase) && !isV2Approver)
    throw new ForbiddenException("Bạn không có quyền xem phiếu này.");

Test defer

4 integration test (List Drafter/V2 approver/non-approver throw 403 + Detail tương tự) — defer carry Plan C bundle khi UAT confirm strict scope stable. Hiện 103/103 PASS regression-free.

Verify

• dotnet build SolutionErp.slnx — 0 err, 2 warn pre-existing
• dotnet test SolutionErp.slnx — 103/103 PASS regression-free

Plan F ABORTED — Pre-flight FAIL

Plan F (drop legacy V1 Mig 32) ABORTED vì pre-flight reveal blocking conditions.

Pre-flight evidence (Prod DB qua SSH vietreport-vps)

Entity	Prod count	Pin status
PurchaseEvaluations với WorkflowDefinitionId	23	V1 ref
PurchaseEvaluations V1-ONLY (no V2 fallback)	4	mất workflow nếu drop
Contracts với WorkflowDefinitionId	7	V1
Contracts với ApprovalWorkflowId	error	column không tồn tại — Contract V2 chưa wire

Blocking conditions

1. Contract entity HOÀN TOÀN dùng V1 — Contract.cs không có property ApprovalWorkflowId. Plan B Contract V2 wire CHƯA kick off. Drop WorkflowDefinitions table sẽ BE crash startup (FK violation 7 contract).

2. 4 phiếu PE V1-only thật trong prod — drop V1 = workflow data loss.

3. 19 phiếu PE V1+V2 mix carry V1 ref — drop column = NULL data, loose audit.

Decision

ABORT Plan F. Defer S22+ sau Plan B Contract V2 wire (Mig 30+31). Order đúng:

1. Plan B Contract V2 wire (Mig 30+31)
2. Migrate 4 phiếu PE V1-only → V2 (admin script)
3. UAT V2 cả 2 module (PE + Contract) 2-3 tuần
4. THEN Plan F drop legacy V1 (Mig 32)

User confirm via AskUserQuestion (4 option) — answer trống → em apply Recommended default ABORT.

Lessons learned

1. Pre-flight prod check BẮT BUỘC cho destructive migration. SSH sqlcmd verify data state TRƯỚC khi drop schema. Plan F pre-flight catch 3 blocking conditions (Contract V1-only + 4 PE V1-only + 19 PE mix) — tránh BE crash startup prod nếu blindly drop.

2. Schema dependency check toàn bộ entity. Plan F focus drop PE V1 nhưng Contract entity cùng V1 schema → liên đới. Audit entity scope ApprovalWorkflowId presence trên Domain trước decision.

3. Test infra reusable Cookie-cutter. Helper SeedWorkflowAsync + SeedApproversAsync pattern dùng cho cả ReturnMode + Guard tests. Future Service test PE/Contract V2 reuse được. Tổng test catch-up 14 test trong ~1.5h, ROI clear.

4. InternalsVisibleTo cleaner than make public. Khi cần test internal helper, dùng InternalsVisibleTo trong csproj thay vì rewrite internal → public — KHÔNG thay đổi public API surface, vẫn chặn external use.

5. Reflection-based regression test cho Authorize policy. Pattern lightweight (5 test ~50 LOC) catch silent 403 regression mà không cần WebApplicationFactory heavy. ROI cực cao cho project có nhiều controller.

Handoff

• ✅ Plan D 60efeed BE+FE Admin User F2 toggle
• ✅ Plan C task 4 dbda37e 5 reflection test #44 silent 403
• ✅ Plan C task 1-3 215b1e0 14 test ReturnMode + Guard
• ✅ Plan E f149661 BE strict V2 scope List + Detail
• ⛔ Plan F ABORTED (pre-flight FAIL — defer sau Plan B Contract V2)
• ⏭ PENDING bro confirm push remote — git push origin main 5 commit ahead 3d725c4..HEAD

User next action expected: Plan B Contract V2 wire (Mig 30+31) là priority cao nhất sau S22 — mở đường cho Plan F drop legacy V1 sau UAT 2-3 tuần.
