# Specification Analysis Report: RFA Approval System Refactor
**Date**: 2026-05-11
**Artifacts Analyzed**: spec.md, plan.md, tasks.md
**Constitution Reference**: AGENTS.md, ADR-019, ADR-009, ADR-008, ADR-016, ADR-002, ADR-007
---
## Findings Summary
| ID | Category | Severity | Location(s) | Summary | Recommendation |
| --- | ----------------- | -------- | --------------------------------- | ----------------------------------------------------- | -------------------------------------------------------- |
| C1 | Constitution | ✅ PASS | tasks.md T066-T070 | Parallel Gateway DSL extension planned | Continue with implementation |
| C2 | Constitution | ✅ PASS | data-model.md all entities | All entities use publicId (UUID) + internal id pattern| Compliant with ADR-019 |
| C3 | Constitution | ✅ PASS | plan.md Technical Context | BullMQ explicitly listed for Reminders/Distribution | Compliant with ADR-008 |
| C4 | Constitution | ✅ PASS | plan.md Constitution Check | All ADR gates marked PASS | Ready for implementation |
| I1 | Inconsistency | LOW | spec.md:FR-004.5, plan.md:T067-T068| Aggregate status calc split between plan and spec | Keep T067, T068 in Phase 9; FR-004.5 already covers requirement |
| C5 | Coverage | ✅ GOOD | All FRs mapped | All 25 FRs have corresponding tasks | No action needed |
| D1 | Duplication | LOW | spec.md, plan.md | Review Teams mentioned in both overview and summary | Keep both; different contexts (user vs technical) |
---
## Detailed Analysis by Category
### 1. Constitution Alignment ✅
| Principle | Status | Evidence |
|-----------|--------|----------|
| **ADR-019 UUID** | ✅ PASS | All entities: `publicId: string (uuid)` + `@Exclude() id: number` |
| **ADR-009 No Migrations** | ✅ PASS | T001 creates SQL schema file; no TypeORM migration mentioned |
| **ADR-002 Document Numbering** | ✅ PASS | Existing RFA numbering reused; no new numbering in scope |
| **ADR-008 BullMQ** | ✅ PASS | T003, T044, T046, T054, T056 explicitly use BullMQ |
| **ADR-016 CASL** | ✅ PASS | Mentioned in FR-025; CASL guards implied in T015, T037 |
| **ADR-007 Error Handling** | ✅ PASS | BusinessException pattern expected in service implementations |
| **No `any` types** | ✅ PASS | All DTOs and entities use explicit types |
| **No `console.log`** | ✅ PASS | NestJS Logger pattern to be used per project standards |

### 3. User Story Coverage
| Story | Priority | Tasks | Independent Test Criteria |
|-------|----------|-------|----------------------------|
| US1 Review Teams | P1 | T014-T023 | Create team → assign to RFA → parallel tasks created |
| US2 Response Codes | P1 | T024-T033 | Review page → category-filtered codes → trigger notification |
| US3 Delegation | P2 | T034-T042 | Delegate → RFA auto-assigned → circular detection blocks |
| US4 Auto-Reminders | P2 | T043-T050 | RFA due soon → reminder sent → overdue → escalation |
| US5 Distribution | P2 | T051-T060 | Approval → distribution queued → recipients notified |
| US6 Matrix Admin | P3 | T061-T065 | View global matrix → create override → project-specific |
### 4. Task Organization Quality
| Phase | Tasks | Testability | Notes |
|-------|-------|-------------|-------|
| Phase 1: Setup | T001-T005 | ✅ Infrastructure | SQL, Seeders, Redis, BullMQ config |
| Phase 2: Foundation | T006-T013 | ✅ Core entities | All 5 core entities created |
| Phase 3: US1 | T014-T023 | ✅ Testable | Review Teams → parallel review |
| Phase 4: US2 | T024-T033 | ✅ Testable | Response Codes → implications |
| Phase 5: US3 | T034-T042 | ✅ Testable | Delegation → circular detection |
| Phase 6: US4 | T043-T050 | ✅ Testable | Reminders → 2-level escalation |
| Phase 7: US5 | T051-T060 | ✅ Testable | Distribution → transmittal |
| Phase 8: US6 | T061-T065 | ✅ Testable | Matrix admin → inheritance |
| Phase 9: Polish | T066-T080 | ✅ Integration | DSL, consensus, tests, edge cases |
### 5. Terminology Consistency
| Concept | Used In | Consistent? |
|---------|---------|-------------|
| ReviewTeam | spec, plan, tasks | ✅ Yes |
| ResponseCode | spec, plan, tasks | ✅ Yes |
| Master Approval Matrix | spec, tasks | ✅ Yes |
| Delegation | spec, plan, tasks | ✅ Yes |
| Distribution Matrix | spec, tasks | ✅ Yes |
| Parallel Review | spec, plan, tasks | ✅ Yes |
| Response Code 1A-1G, 2, 3, 4 | spec (master table) | ✅ Yes, exact match |
### 6. Dependency Graph Validation
**Verified Dependencies**:
- Phase 1 → Phase 2: Setup entities needed for all stories ✅
- Phase 2 → Phase 3-8: Core entities required ✅
- Phase 3-8 → Phase 9: Integration requires all stories ✅
- Phase 3 (US1) ↔ Phase 4 (US2): Independent, can parallelize ✅
### 7. Edge Case Coverage
| Edge Case from spec.md | Covered in Tasks | Status |
|------------------------|------------------|--------|
| Race Condition (concurrent review) | T066, T069, T070 | ✅ Redlock + Optimistic locking |
| Circular Delegation | T036 | ✅ Detection algorithm |
| Expired Review Task | T035 (endDate handling) | ✅ Auto-expiry logic |
| Invalid Response Code | T026 (implications evaluator) | ✅ Validation layer |
| Concurrent Review veto | T068 (consensus service) | ✅ Majority with veto |
---
## Metrics Summary
| Metric | Value | Target | Status |
|--------|-------|--------|--------|
| Total Requirements | 25 | - | - |
| Requirements with Tasks | 25 | 100% | ✅ |

## Risk Assessment
| Risk | Probability | Impact | Mitigation in Plan |
|------|-------------|--------|-------------------|
| DSL Parallel Gateway complexity | Medium | High | T066, T067, prototype recommended in MVP |
| Response Code migration | Low | Medium | New tables only, existing data untouched |
| Performance on large teams | Low | Medium | T067 aggregate status, Redis caching |
| Circular delegation edge cases | Low | Low | T036, T075 unit tests |
| BullMQ queue failures | Low | High | T046, T056 processors with retry logic |
---
## Next Actions
### Immediate ✅
**Ready for `/speckit-implement`**
The specification, plan, and tasks are:
- ✅ Constitution compliant (no violations)
- ✅ 100% requirement coverage
- ✅ All user stories have independent test criteria
- ✅ All edge cases addressed
- ✅ Dependency graph validated
- ✅ 80 tasks defined across 9 phases
### Recommended Implementation Order
1. **MVP Approach**: Phases 1-2 → US1 (Phase 3) → Minimal Phase 9
- Delivers Review Teams + Parallel Review first
- Early value, lower risk
2. **Full Implementation**: All phases sequentially
- Complete feature set
- Higher coordination needed
### Suggested Commands
```bash
# Start implementation
/speckit-implement
# Or start with specific phase
/speckit-implement --phase 1-2
# Run tests after each phase
/speckit-tester
```
---
## Remediation Offers
No critical remediation required. The following are **optional improvements**:
1. **LOW**: Consider merging T067/T068 into a single AggregateStatusService if they share significant code
2. **LOW**: Add specific performance benchmarks to tasks T001 (SQL indexes) for clarity
**No action required before implementation.**

|--------|------|----------------|
| ReviewTask | Cannot assign completed task | Check status before update |
| Delegation | No circular chains | BFS/DFS validation on create |
| Delegation | Max 3 levels deep | Enforce in service layer |
| ResponseCodeRule | Only one enabled per doc type + code per project | Unique constraint |
| ReviewTeam | At least one member with LEAD role | Validate on activation |
---
## Next Steps
1. Generate SQL schema file (follows ADR-009: no TypeORM migrations)
2. Create TypeORM entities in `backend/src/modules/`
3. Create API contracts in `contracts/`

# Implementation Plan: RFA Approval System Refactor
**Branch**: `1-rfa-approval-refactor` | **Date**: 2026-05-11 | **Spec**: [spec.md](./spec.md)
**Input**: Refactor RFA approval system to TeamBinder/InEight-style with Review Teams, Response Codes, Delegation, Auto-Reminders, and Distribution Matrix
---
## Summary
ปรับปรุงระบบการอนุมัติเอกสาร RFA ให้รองรับ:
1. **Review Teams by Discipline** - กำหนผู้ตรวจสอบตามสาขาวิชาแทนรายบุคคล พร้อม Parallel Review
2. **Master Approval Matrix** - Response Codes มาตรฐาน 1A-1G, 2, 3, 4 ตามหมวดงาน (Engineering, Material, Contract, Testing, ESG)
3. **Delegation & Proxy** - มอบหมายงานแทนเมื่อไม่อยู่ พร้อมตรวจจับ Circular Delegation
4. **Auto-Reminders & Escalation** - แจ้งเตือนอัตโนมัติตาม SLA และ Escalate 2 ระดับเมื่อ Overdue
5. **Distribution Matrix** - กระจายเอกสารอัตโนมัติหลังอนุมัติผ่าน BullMQ
Technical approach: สร้าง Entities ใหม่ (ReviewTeam, ReviewTask, ResponseCodeMatrix, Delegation, DistributionMatrix) และ integrate กับ Unified Workflow Engine (ADR-001) และ BullMQ (ADR-008)
---
## Technical Context
**Language/Version**: TypeScript 5.x, NestJS 10.x (Backend), Next.js 14.x (Frontend)
**Primary Dependencies**: TypeORM (Database), BullMQ (Queue/Reminders), CASL (Authorization), Zod (Validation), Redis (Cache/Locking)
**Storage**: MariaDB 10.11 (Primary), Redis 7.x (Cache/Queue)
**Testing**: Jest (Backend), Playwright (Frontend), Min 70% backend coverage, 80% business logic
**Target Platform**: Web Application (NestJS API + Next.js Frontend)
**Project Type**: Full-stack (backend + frontend)
**Performance Goals**: Approval API response <500ms, Parallel Review aggregation <200ms, Distribution queue processing <5 min
**Constraints**: ADR-019 UUID (no parseInt), ADR-009 No TypeORM Migrations, ADR-002 Document Numbering with Redlock, ADR-018 AI Boundary
**Scale/Scope**: 100+ concurrent RFAs, 50+ Review Teams per project, 1000+ Distribution recipients
---
## Constitution Check
| Gate | Status | Notes |
|------|--------|-------|
| **ADR-019 UUID** | ✅ PASS | All new entities use publicId (string UUID), internal id (number) with @Exclude() |
| **ADR-009 No Migrations** | ✅ PASS | Schema changes via SQL files in `specs/03-Data-and-Storage/` |
| **ADR-002 Document Numbering** | ✅ PASS | Existing RFA numbering reused, no new numbering needed |
| **ADR-008 BullMQ** | ✅ PASS | Reminders, Distribution, Escalation all use BullMQ |
| **ADR-016 CASL** | ✅ PASS | Reviewer permissions via CASL ability checks |
| **ADR-018 AI Boundary** | ✅ PASS | No AI involvement in approval workflow |
| **ADR-007 Error Handling** | ✅ PASS | BusinessException/WorkflowException for approval errors |
| **No `any` types** | ✅ PASS | Strict TypeScript enforced |
| **No `console.log`** | ✅ PASS | NestJS Logger for backend, removed for frontend commits |
**Post-Design Re-check**: Required after data-model.md and contracts generated

**Structure Decision**: Full-stack implementation with 5 new backend modules (review-team, response-code, delegation, reminder, distribution) + modifications to existing rfa and workflow-engine modules. Frontend adds management UIs and enhances existing RFA review page.
---
## Complexity Tracking
| Violation | Why Needed | Simpler Alternative Rejected Because |
|-----------|------------|--------------------------------------|
| 5 new backend modules | Each domain (Review Teams, Response Codes, Delegation, Reminders, Distribution) has distinct business logic, lifecycle, and scaling needs | Single combined module would create tight coupling and maintenance burden |
| Parallel Review in Workflow Engine | Requires significant DSL extension to support concurrent tasks with consensus rules | Sequential review would not meet industry standard (TeamBinder/InEight) efficiency requirements |
| Master Approval Matrix with inheritance | Global + Project override needed for standardization while allowing project flexibility | Single global matrix wouldn't accommodate project-specific requirements (e.g., ESG varies by project type) |
---
## Phase Overview
| Phase | Output | Purpose |
|-------|--------|---------|
| **Phase 0** | research.md | Research technical patterns, validate Workflow Engine DSL extension |
| **Phase 1** | data-model.md, contracts/, quickstart.md | Design entities, API contracts, setup guide |
| **Phase 2** | tasks.md | Break into actionable tasks (via /speckit-tasks) |
---
## Next Steps
1. **Phase 0**: Generate research.md - Validate Workflow Engine DSL can support Parallel Review
2. **Phase 1**: Generate data-model.md and API contracts
3. **Run**: `/speckit-tasks` to create tasks.md
4. **Run**: `/speckit-analyze` to validate cross-artifact consistency

```
---
## 6. Verification Checklist
- [ ] Review Team created and visible in admin
- [ ] Review Team members assigned by discipline
- [ ] RFA submission creates parallel review tasks
- [ ] Response codes filtered by document category
- [ ] Code 3 triggers veto and returns workflow
- [ ] Reminders scheduled on due date
- [ ] Distribution executes after approval
- [ ] Delegation forwards tasks correctly
- [ ] Aggregate status shows real-time progress
---
## 7. Troubleshooting
### Queue Jobs Not Processing
```bash
# Check BullMQ board (if enabled)
open http://localhost:3001/admin/queues
# Or check Redis
redis-cli KEYS "bull*"
redis-cli LRANGE "bull:rfa-reminders:waiting" 0 -1
```
### Parallel Review Not Working
Check workflow-engine DSL configuration:
```bash
# Verify parallel gateway enabled
curl http://localhost:3001/api/v1/workflow-definitions/RFA_APPROVAL \
-H "Authorization: Bearer $TOKEN"
```
### Response Codes Not Loading
```bash
# Verify seed data
mysql -u root -p lcbp3 -e "SELECT COUNT(*) FROM response_codes;"
# Expected: 55 rows minimum
```
---
## 8. Next Steps
1. **Run Tests**: `npm test` (backend), `npm run test:e2e` (frontend)
2. **Load Test**: `k6 run load-tests/rfa-approval-load.js`
3. **Deploy**: Follow `specs/04-Infrastructure-OPS/04-08-release-management-policy.md`

# Phase 0 Research: RFA Approval System Refactor
**Date**: 2026-05-11
**Purpose**: Research technical patterns and validate design decisions
---
## Research Topics
### 1. Parallel Review in Workflow Engine
**Research Task**: Can Unified Workflow Engine (ADR-001) support parallel tasks with consensus rules?
**Decision**: ✅ **Yes, with DSL Extension**
**Rationale**:
- Current DSL supports sequential states and transitions
- Parallel review requires: (a) Task splitting on state entry, (b) Task aggregation before transition, (c) Consensus rule evaluation
- Pattern: `ParallelGateState` - enters sub-workflows for each Discipline, aggregates on completion
**Implementation Pattern**:
```typescript
// DSL Extension: Parallel Gateway
{
type: 'parallel_gateway',
config: {
discriminator: 'discipline', // Split by discipline
minCompletion: 'majority', // Consensus rule
vetoConditions: [{ field: 'responseCode', value: '3' }] // Veto triggers
}
}
```
**Alternatives Considered**:
- Option A: Multiple Workflow Instances per RFA (rejected - too complex, hard to aggregate)
- Option B: Sequential with fast-forward (rejected - doesn't truly parallelize)
- Option C: **Parallel Gateway in DSL** (selected - clean abstraction, reusable pattern)
**References**:
- BPMN 2.0 Parallel Gateway pattern
- Existing `workflow-dsl.schema.ts` in codebase
---
### 2. Response Code Matrix Storage
**Research Task**: Best structure for Master Approval Matrix with 5 categories × 11 codes?
**Decision**: **Normalized Relational Model with JSON for flexibility**
**Rationale**:
- Core codes (1A-1G, 2, 3, 4) are stable relational data
- Category mappings (which codes apply to which doc types) need flexibility
- Project overrides need inheritance tracking
**Schema Design**:
```sql
-- Core Response Codes (stable)
response_codes (id, code, sub_status, description_th, description_en, category)
-- Matrix Rules (project-specific overrides)
response_code_rules (
id,
project_id NULLABLE, -- NULL = global default
document_type_id,
response_code_id,
is_enabled,
requires_comments,
triggers_notification,
parent_rule_id -- For inheritance tracking
)
```
**Alternatives Considered**:
- Single JSON column for entire matrix (rejected - hard to query, validate, index)
- Full EAV (Entity-Attribute-Value) (rejected - too complex for this use case)
---
### 3. Delegation Pattern & Circular Detection
**Research Task**: Best approach for delegation with chain depth limit and circular detection?
**Decision**: **Adjacency List with Path Enumeration, Max Depth = 3**
**Rationale**:
- Adjacency List: Simple, fast for immediate lookup (`delegator_id → delegatee_id`)
- Path Enumeration: Store full chain as array for circular detection
- Max Depth 3: Prevents runaway chains while supporting realistic use cases
**Circular Detection Algorithm**:
```typescript
function detectCircularDelegation(delegatorId: string, proposedDelegateeId: string): boolean {
// BFS/DFS from proposedDelegatee, check if can reach delegatorId
const visited = new Set<string>();
const queue = [proposedDelegateeId];
while (queue.length > 0) {
const current = queue.shift()!;
if (current === delegatorId) return true; // Circular!
if (visited.has(current)) continue;
visited.add(current);
// Add all delegatees of current
const delegatees = getActiveDelegations(current);
queue.push(...delegatees.map(d => d.delegateeId));
}
return false;
}
```
**Alternatives Considered**:
- Nested Set Model (rejected - overkill for simple chains)
- Closure Table (rejected - requires maintenance on delegation expiry)
---
### 4. BullMQ Pattern for Reminders & Distribution
**Research Task**: Best BullMQ patterns for scheduled reminders and async distribution?
**Decision**: **Delayed Jobs + Repeatable Jobs + Flows**
**Pattern Breakdown**:
**Reminders**:
- **Delayed Jobs**: Schedule individual reminder at due date
- **Repeatable Jobs**: Daily reminder for overdue items (cron pattern)
- **Job Data**: `{ rfaId, reviewerId, reminderType, escalationLevel }`
**Distribution**:
- **Job Flow**: Parent (distribution coordinator) → Children (individual deliveries)
- **Retry**: 3 attempts with exponential backoff
- **Dead Letter**: Failed distributions logged for manual intervention
```typescript
// Reminder Queue Pattern
await reminderQueue.add('rfa-reminder', {
rfaRevisionId,
reviewerId,
reminderType: 'DUE_SOON'
}, {
delay: calculateDelay(dueDate, reminderDaysBefore)
});
// Distribution Flow Pattern
await distributionFlow.add({
name: 'rfa-distribution',
data: { rfaId, responseCode, recipients: [...] },
children: recipients.map(r => ({
name: 'deliver-document',
data: { recipientId: r.id, method: r.deliveryMethod }
}))
});
```
**Alternatives Considered**:
- node-cron for scheduling (rejected - no persistence, no retry)
- Custom scheduler service (rejected - BullMQ already provides this)
---
### 5. Review Task Status Aggregation
**Research Task**: How to efficiently calculate aggregate status for parallel reviews?
**Decision**: **Materialized View + Real-time Counter**
**Rationale**:
- Materialized View: Fast reads for list views ("2 of 3 approved")
- Real-time Counter: Immediate update on each review action
- Trigger: Update counter on ReviewTask status change
**Aggregation Logic**:
```sql
-- Materialized view for fast reads
CREATE VIEW review_task_summary AS
SELECT
rfa_revision_id,
COUNT(*) as total_disciplines,
SUM(CASE WHEN status = 'COMPLETED' THEN 1 ELSE 0 END) as completed,
SUM(CASE WHEN response_code = '3' THEN 1 ELSE 0 END) as rejected_count
FROM review_tasks
GROUP BY rfa_revision_id;
-- Real-time consensus check
SELECT CASE
WHEN rejected_count > 0 THEN 'REJECTED' -- Veto triggered
WHEN completed = total_disciplines THEN
CASE
WHEN approved_count / total_disciplines >= 0.5 THEN 'APPROVED'
ELSE 'NEEDS_REVIEW'
END
ELSE 'IN_PROGRESS'
END as consensus_status
FROM review_task_summary;
```
**Alternatives Considered**:
- Calculate on-demand (rejected - slow with many disciplines)
- Application-level cache (rejected - stale data risk)
---
## Summary of Decisions
| Topic | Decision | Key Rationale |
|-------|----------|---------------|
| Parallel Review | DSL Parallel Gateway | Clean abstraction, reusable |
| Response Code Storage | Normalized + JSON | Balance of structure and flexibility |
| Delegation | Adjacency List + Path Enum | Simple, sufficient for depth ≤3 |
| Queue Pattern | BullMQ Delayed + Flows | Industry standard, reliable |
| Status Aggregation | Materialized View + Counter | Fast reads, real-time updates |
---
## Risk Assessment
| Risk | Probability | Mitigation |
|------|-------------|------------|
| DSL Parallel Gateway complexity | Medium | Prototype with simple 2-discipline case first |
| Response Code migration from existing | Low | New tables, existing data untouched |
| Performance on large Review Teams | Low | Pagination on aggregation, Redis caching |
| Circular delegation algorithm | Low | Unit test with 3-level chains |
---
## Next Phase
**Phase 1**: Design data model and API contracts based on these research decisions.

# Feature Specification: RFA Approval System Refactor (TeamBinder/InEight-Style)
**Feature Branch**: `1-rfa-approval-refactor`
**Created**: 2026-05-11
**Status**: Draft
**Input**: User description: "refactor ระบบการอนุมัติเอกสาร, RFA ให้เหมือนกับ TeamBinder หรือ InEight"
---
## Overview
ปรับปรุงระบบการอนุมัติเอกสาร RFA (Request for Approval) ให้มีความยืดหยุ่นและครบถ้วนตามมาตรฐานระดับสูงของอุตสาหกรรมก่อสร้าง (TeamBinder, InEight) รองรับการทำงานแบบ Multi-Disciplinary Review, Response Codes มาตรฐาน, และ Distribution Matrix อัตโนมัติ
---
## User Scenarios & Testing
### User Story 1 - Review Teams by Discipline (Priority: P1)
ผู้จัดการโครงการสามารถกำหนดกลุ่มผู้ตรวจสอบ (Review Teams) ตามสาขาวิชา (Disciplines) แทนการระบุรายบุคคล เพื่อให้การมอบหมายงานยืดหยุ่นและรวดเร็ว
**Why this priority**: ฟีเจอร์หลักที่แยกระบบปัจจุบันกับมาตรฐานอุตสาหกรรม - ช่วยลดเวลาในการกำหนดผู้ตรวจสอบและรองรับการเปลี่ยนแปลงบุคคลในโครงการ
**Independent Test**: สามารถทดสอบโดยสร้าง Review Team ที่มีหลาย Disciplines และส่ง RFA เข้า workflow - ระบบต้องสามารถมอบหมายให้ทุก Discipline พร้อมกันได้
**Acceptance Scenarios**:
1. **Given** ผู้ใช้มีสิทธิ์จัดการ Review Teams, **When** สร้าง Review Team ใหม่ชื่อ "Structural Review Team" พร้อมกำหนด Disciplines: Structural, Civil, **Then** ระบบบันทึกทีมและสามารถใช้กับ RFA ได้
2. **Given** RFA ถูกส่งเข้า workflow และใช้ Review Team ที่มี 3 Disciplines, **When** ระบบประมวลผล, **Then** สร้าง Review Tasks สำหรับแต่ละ Discipline พร้อมกัน
3. **Given** Reviewer ในทีมเปลี่ยนตำแหน่งหรือลาออก, **When** Admin อัปเดตสมาชิกใน Review Team, **Then** RFA ที่รออยู่ต้องอัปเดตผู้รับผิดชอบโดยอัตโนมัติ
---
### User Story 2 - Response Codes & Sub-Status (Priority: P1)
วิศวกรสามารถเลือก Response Code มาตรฐาน (1A, 1B, 1C, 2, 3, 4) พร้อม Sub-Status ที่บ่งบอกความหมายเฉพาะทาง เพื่อสื่อสารสถานะงานได้ชัดเจนและสอดคล้องกับมาตรฐานอุตสาหกรรม
**Why this priority**: ปรับปรุงการสื่อสารระหว่างฝ่ายต่างๆ ลดความกำกวมในการอนุมัติ และสนับสนุนการทำ Final Acceptance Certificate (FAC)
**Independent Test**: สามารถทดสอบโดยเปิดหน้าอนุมัติ RFA และตรวจสอบว่า Response Codes แสดงตาม Category ของเอกสาร - เลือก Code 1C ต้องมีการแจ้งเตือนฝ่ายสัญญา
**Acceptance Scenarios**:
1. **Given** RFA ประเภท Shop Drawing, **When** Reviewer เปิดหน้าอนุมัติ, **Then** แสดงเฉพาะ Response Codes ที่เกี่ยวข้องกับ Engineering/Drawings (1A-1G, 2, 3, 4)
2. **Given** Reviewer เลือก Code 1C (Change Order) หรือ 1D (Alternative), **When** บันทึกการอนุมัติ, **Then** ระบบส่งแจ้งเตือนไปยังฝ่ายสัญญา/BOQ อัตโนมัติ
3. **Given** RFA ได้รับ Code 2 (Approved as Noted), **When** ดูรายงานสถานะ, **Then** แสดงสถานะ "Approved with Minor Comments" พร้องานที่ต้องแก้ไข
---
### User Story 3 - Delegation & Proxy (Priority: P2)
ผู้ตรวจสอบสามารถมอบหมายอำนาจ (Delegate) ให้ผู้อื่นทำงานแทนเมื่อไม่อยู่หรือไม่สะดวก โดยกำหนดระยะเวลาและขอบเขตอำนาจได้
**Why this priority**: ป้องกันการคั่งค้างของ workflow เมื่อผู้ตรวจสอบไม่ว่าง รองรับการทำงานแบบ Hybrid/Remote
**Independent Test**: สามารถทดสอบโดยผู้ใช้ A ตั้งค่า Delegate ให้ผู้ใช้ B แล้วส่ง RFA มา - ผู้ใช้ B ต้องเห็นงานใน Inbox และสามารถอนุมัติแทนได้
**Acceptance Scenarios**:
1. **Given** ผู้ใช้ต้องการลาพักร้อน 1 สัปดาห์, **When** ตั้งค่า Delegation ให้ colleague พร้อมระบุวันที่เริ่ม-สิ้นสุด, **Then** งานที่ส่งมาระหว่างนี้ไปที่ Delegatee โดยอัตโนมัติ
2. **Given** มีงาน RFA รออยู่ใน Inbox และผู้ใช้ตั้งค่า Delegation ไว้, **When** มีการส่งงานใหม่เข้ามา, **Then** ระบบมอบหมายให้ Delegatee พร้อมแสดงว่าเป็น "Delegated from [Original User]"
3. **Given** Delegation หมดอายุ, **When** มีงานใหม่ส่งมา, **Then** งานกลับมาที่ผู้ใช้เจ้าของงานเดิม และยกเลิกสิทธิ์ Delegatee
---
### User Story 4 - Auto-Reminders & Escalation (Priority: P2)
ระบบส่งการแจ้งเตือนอัตโนมัติเมื่องานใกล้ครบกำหนด และส่งขึ้นระดับ (Escalate) เมื่อเกินกำหนด ตาม SLA ที่กำหนดไว้
**Why this priority**: ลดความล่าช้าใน workflow และปรับปรุง on-time delivery rate ของเอกสาร
**Independent Test**: สามารถทดสอบโดยสร้าง RFA ที่มี Due Date ในอีก 1 วัน และตรวจสอบว่าระบบส่ง Reminder ตามที่ตั้งค่าไว้
**Acceptance Scenarios**:
1. **Given** RFA มี Due Date ในอีก 2 วัน, **When** ถึงเวลา 9:00 ของวันที่ตั้งค่า Reminder, **Then** ส่งอีเมล/แจ้งเตือนไปยังผู้รับผิดชอบ
2. **Given** RFA เกินกำหนด 1 วัน, **When** ถึงเงื่อนไข Escalation, **Then** ส่งแจ้งเตือนไปยัง Manager ของผู้รับผิดชอบ พร้อมสถานะ Overdue
3. **Given** Admin ตั้งค่า Reminder Frequency เป็น "Daily" สำหรับงาน Overdue, **When** งานค้างเกินกำหนด, **Then** ส่ง Reminder ทุกวันจนกว่าจะดำเนินการ
---
### User Story 5 - Distribution Matrix (Priority: P2)
ระบบกระจายเอกสารอัตโนมัติไปยังผู้ที่เกี่ยวข้องหลังจาก RFA ได้รับการอนุมัติ ตาม Distribution Matrix ที่กำหนดไว้ตามประเภทเอกสารและ Response Code
**Why this priority**: ลด manual work ในการส่งเอกสารต่อ ป้องกันการส่งตกหล่น และสนับสนุนการทำ Transmittal อัตโนมัติ
**Independent Test**: สามารถทดสอบโดยอนุมัติ RFA ที่มี Distribution Matrix แล้วตรวจสอบว่าเอกสารถูกส่งไปยังผู้รับที่กำหนดใน Matrix โดยอัตโนมัติ
**Acceptance Scenarios**:
1. **Given** RFA ประเภท Shop Drawing ได้รับ Code 1A (Full Approval), **When** อนุมัติสำเร็จ, **Then** ระบบส่งเอกสารไปยัง Site Team, QS, และ Document Control ตาม Distribution Matrix
2. **Given** Distribution Matrix มีเงื่อนไข "Send only if Code = 1A, 1B, or 2", **When** RFA ได้รับ Code 3 (Rejected), **Then** ไม่ส่งเอกสารตาม Matrix (แจ้งเฉพาะผู้ส่ง)
3. **Given** Admin อัปเดต Distribution Matrix เพิ่มผู้รับใหม่, **When** RFA ถัดไปได้รับการอนุมัติ, **Then** ส่งเอกสารไปยังผู้รับใหม่ด้วย
---
### User Story 6 - Master Approval Matrix Management (Priority: P3)
ผู้ดูแลระบบสามารถจัดการ Master Approval Matrix ที่เป็นมาตรฐานขององค์กร แยกตามหมวดงานและสถานะย่อย ให้ใช้งานทั่วทั้งโครงการ
**Why this priority**: มาตรฐานการอนุมัติให้สอดคล้องกับบริษัทและอุตสาหกรรม ลดความสับสนในการใช้ Response Codes
**Independent Test**: สามารถทดสอบโดยสร้าง Master Approval Matrix ใหม่ และตรวจสอบว่า RFA แสดง Response Codes ตาม Matrix ที่กำหนด
**Acceptance Scenarios**:
1. **Given** Admin ต้องการสร้างมาตรฐานใหม่สำหรับโครงการก่อสร้างสะพาน, **When** สร้าง Master Approval Matrix พร้อมกำหนดหมวดงานและ Sub-status, **Then** สามารถใช้กับโครงการที่เลือกได้
2. **Given** Master Approval Matrix ถูกใช้งานในโครงการหลายแห่ง, **When** Admin แก้ไข Matrix, **Then** ระบบแสดง Warning ว่าจะมีผลกับโครงการที่ใช้งานอยู่
---
### Edge Cases
1. **Race Condition**: สอง Reviewer ในทีมเดียวกันกดอนุมัติพร้อมกัน - ระบบต้องจัดการด้วย Optimistic Locking หรือ Redlock
2. **Circular Delegation**: ผู้ใช้ A Delegate ให้ B, B Delegate ให้ C, C พยายาม Delegate ให้ A - ระบบต้องตรวจจับและป้องกัน
3. **Expired Review Task**: Review Task ค้างนานเกินกำหนดและถูก Reassign - ต้องบันทึกประวัติการเปลี่ยนแปลง
4. **Invalid Response Code**: Reviewer พยายามใช้ Response Code ที่ไม่สอดคล้องกับ Category ของเอกสาร - ระบบต้องแสดงข้อผิดพลาดและไม่บันทึก
5. **Concurrent Review**: หลาย Disciplines ต้อง Review พร้อมกัน แต่มี Discipline หนึ่งปฏิเสธ - ต้องหยุด workflow และแจ้งผู้ส่ง

---
## Clarifications
### Session 2026-05-11
- **Q1**: Master Approval Matrix scope and inheritance model? → **A**: Global base + Project overrides - Default Matrix inherited organization-wide, projects can override specific codes/rules as needed (Option B)
- **Q2**: Parallel Review consensus model when Disciplines have conflicting decisions? → **A**: Majority with veto - All Disciplines submit responses, majority determines outcome, but Code 3 (Rejected) from any Discipline vetoes approval and requires revision (Option C)
- **Q3**: Escalation chain depth for overdue RFA reviews? → **A**: 2 levels - Direct manager first, then Project Manager/Director if still unresolved after additional delay (Option B)
- **Q4**: Distribution Matrix execution timing relative to approval? → **A**: Async after approval - Approval returns immediately, distribution queued via BullMQ and processed automatically within 5 minutes (Option C)
- **Q5**: Frontend pattern for displaying Parallel Review progress? → **A**: Horizontal Stepper - แถบความคืบหนันแนวนอนแสดงสถานะแต่ละ Discipline (Option A)
- **Q6**: How to display Veto/Consensus status when Code 3 triggered? → **A**: Modal Dialog - Popup แจ้งเมื่อมีการ Veto พร้อมรายละเอียด Discipline ที่ reject (Option B)
- **Q7**: Navigation pattern between Discipline details for Reviewer? → **A**: Side Panel - ซ้ายรายการ Disciplines, ขวาแสดงรายละเอียดที่เลือก (Option D)
- **Q8**: Can Veto be overridden and by whom? → **A**: Project Manager Override - PM สามารถบังคับผ่าน Veto ได้ พร้อมบันทึกเหตุผล และแจ้งเตือนทุก stakeholder (Option B)
---
## Assumptions
1. **ผู้ใช้มีความคุ้นเคยกับ Response Codes มาตรฐานอุตสาหกรรม** - จำเป็นต้องมี Training Material ประกอบ
2. **โครงสร้าง Discipline Master Data มีอยู่แล้ว** - ใช้จากระบบ User Management ที่มีอยู่
3. **Unified Workflow Engine (ADR-001) มีความสามารถรองรับ Parallel Tasks** - อาจต้องปรับปรุง DSL
4. **BullMQ Infrastructure พร้อมใช้งาน** - สำหรับ Reminders และ Background Jobs
---
## Dependencies
- **ADR-001**: Unified Workflow Engine (ต้องรองรับ Parallel Review Tasks)
- **ADR-008**: BullMQ Notification Strategy
- **ADR-016**: CASL Authorization (สำหรับ Reviewer สิทธิ์)
- **ADR-019**: UUID Strategy (สำหรับ Entities ใหม่)
- **ADR-021**: Workflow Context (สำหรับ Step Attachments)
- **Existing**: Discipline, User, Organization Master Data
---
## Risks & Mitigations
| Risk | Impact | Mitigation |
|------|--------|------------|
| ผู้ใช้ไม่คุ้นเคยกับ Response Codes ใหม่ | High | ทำ Training Workshop พร้อม Quick Reference Guide |
| Workflow Engine ไม่รองรับ Parallel Review | High | ประเมิน DSL ก่อนเริ่ม, อาจต้อง Refactor Engine |
| Performance ช้าจาก Complex Matrix Lookup | Medium | ทำ Caching สำหรับ Matrix และ Rules |
| Circular Delegation ซับซ้อน | Low | Validation ตั้งแต่ต้น, Limit depth ของ chain |

## MVP Scope (Minimum Viable Product)
For fastest value delivery, implement:
1. **Phase 1-2**: Setup and entities
2. **Phase 3**: US1 Review Teams only
3. **Phase 9**: Basic consensus + edge case handling (skip US2-US6)
**MVP Deliverables**:
- Review Teams with Disciplines
- Parallel review task creation
- Basic response code selection (no category filtering)
- Simple sequential workflow (no parallel gateway in DSL yet)

## Next Steps
1. **Execute Phase 1-2**: Setup and entities
2. **Run `/speckit-analyze`**: Validate cross-artifact consistency
3. **Implement incrementally**: Start with MVP (Phases 1-3 + minimal Phase 9)
4. **Test independently**: Each user story should be independently testable
