- 2026-06-05 (Session 13): OCR Sandbox Step 2 AI Extraction Bug Fix — แก้ปัญหา "Not Found Exception" ใน Step 2 AI Extraction โดยเพิ่ม conditional check ใน processSandboxExtract และ processSandboxAiExtract เพื่อส่ง undefined แทน 'default' projectPublicId ไปยัง resolveContext (เพราะ 'default' ไม่ใช่ project UUID ที่ถูกต้อง). Frontend: เพิ่ม startPolling method ใน useSandboxRun hook เพื่อรองรับ 2-step flow และแก้ OcrSandboxPromptManager.tsx ให้ใช้ startPolling แทน custom polling logic. Model Switching Analysis: Production OCR Extraction มี model switching (unload main → load OCR model → run → reload main) เพื่อประหยัด VRAM แต่ Sandbox AI Extraction ไม่มี model switching เพราะใช้ main model สกัด metadata จาก OCR text ที่มาจาก Step 1 (Tesseract OCR sidecar) แล้ว ไม่ใช่ OCR model. OCR Sidecar Location: specs/04-Infrastructure-OPS/04-00-docker-compose/Desk-5439/ocr-sidecar/ (ใช้ Tesseract OCR ไม่ใช่ PaddleOCR ตั้งแต่ 2026-05-30). Model Config: เพิ่ม SYSTEM prompt ภาษาไทยใน typhoon2.5-np-dms.model.md และ typhoon2.5-np-dms.main-model.md สำหรับ LCBP3 DMS context

Model Switching Analysis: Production OCR Extraction มี model switching (unload main → load OCR model → run → reload main) เพื่อประหยัด VRAM แต่ Sandbox AI Extraction ไม่มี model switching เพราะใช้ main model สกัด metadata จาก OCR text ที่มาจาก Step 1 (Tesseract OCR sidecar) แล้ว ไม่ใช่ OCR model. OCR Sidecar Location: specs/04-Infrastructure-OPS/04-00-docker-compose/Desk-5439/ocr-sidecar/ (ใช้ Tesseract OCR ไม่ใช่ PaddleOCR ตั้งแต่ 2026-05-30). Model Config: เพิ่ม SYSTEM prompt ภาษาไทยใน typhoon2.5-np-dms.model.md และ typhoon2.5-np-dms.main-model.md สำหรับ LCBP3 DMS context

### Session 14 — 2026-06-05 (RAG Pipeline Enhancements / Spec 234 / ADR-035) ← **ล่าสุด**
|
||||||
|
|
||||||
|
**Summary:** ปรับโค้ดให้สอดคล้องกับ feature `234-rag-pipeline-enhancements` และ `ADR-035-ai-pipeline-flow-architecture` โดยปิด compile blockers ของ RAG pipeline ใหม่, บังคับ tenant scope ผ่าน `projectPublicId` ใน vector deletion path, ย้าย dashboard ไปใช้ `/ai/rag/*`, และ retire runtime surface ของ legacy `/rag/*`
|
||||||
|
|
||||||
|
**Backend Changes (B1-B6):**
|
||||||
|
|
||||||
|
- **Compile blockers fixed (4 จุด):**
|
||||||
|
- ปรับ `ai-batch.processor.ts` ให้ legacy `embed-document` path ส่งข้อมูลตาม signature ใหม่ของ `EmbeddingService.embedDocument(...)`
|
||||||
|
- เพิ่ม `projectPublicId` ใน `AiVectorDeletionJobPayload` และ propagate ผ่าน `AiQueueService` + `vector-deletion.processor.ts`
|
||||||
|
- ปรับ typing ใน `src/modules/ai/qdrant.service.ts` ให้รองรับ hybrid upsert contract ของ Qdrant client
|
||||||
|
- แก้ nullability ใน `correspondence-workflow.service.ts` สำหรับ trigger `enqueueRagPrepare()`
|
||||||
|
- **Legacy delete path hardening:** `backend/src/modules/rag/rag.service.ts` เปลี่ยน `deleteVectors()` ให้ resolve `projectPublicId` จาก `DocumentChunk`/server-side context ก่อน ไม่เชื่อ query param จาก client เป็นหลัก
|
||||||
|
- **Legacy runtime deprecation:** mark `backend/src/modules/rag/rag.controller.ts` และ endpoint summaries เป็น deprecated ชั่วคราวระหว่าง audit
|
||||||
|
- **Legacy runtime removal:** หลัง consumer audit ใน repo ไม่พบ caller ของ `/rag/status`, `/rag/ingest`, `/rag/vectors`, `/rag/admin/init-collection`, จึงถอด `RagModule` ออกจาก `backend/src/app.module.ts` และลบ `backend/src/modules/rag/rag.controller.ts` + `rag.module.ts`
|
||||||
|
|
||||||
|
**Frontend Changes (F1-F2):**
|
||||||
|
|
||||||
|
- **Dashboard RAG migration:** `frontend/app/(dashboard)/rag/page.tsx` เปลี่ยนมาใช้ `RagChatWidget` ซึ่งวิ่งผ่าน `POST /ai/rag/query` และ `GET /ai/rag/jobs/:requestPublicId`
|
||||||
|
- **Legacy frontend cleanup:** ลบ `frontend/hooks/use-rag.ts` และ `frontend/components/rag/*` ที่ไม่ถูกใช้งานแล้ว
|
||||||
|
|
||||||
|
**Architecture / Documentation Updates:**
|
||||||
|
|
||||||
|
- **ADR-035:** เพิ่มและอัปเดต Legacy Compatibility Note ให้สะท้อนสถานะจริงของ migration ไป `/ai/rag/*`
|
||||||
|
- **Current runtime state:** `/rag/*` ไม่ถูก mount ใน `AppModule` แล้ว; flow หลักของระบบใช้ `AiModule` + `/ai/rag/*`
|
||||||
|

||||||

|
- `pnpm exec tsc --noEmit -p frontend/tsconfig.json` — ✅ ผ่าน
|
||||||
|
|
||||||
|
**Follow-up Completed (Session 14+):**
|
||||||
|
|
||||||
|
- ✅ แก้ `backend/src/modules/ai/qdrant.service.ts` — `ensureCollection()` ตรวจ schema ก่อน delete: ถ้าเป็น Hybrid 1024 dims แล้ว skip recreation
|
||||||
|
- ✅ ย้าย `rag-prepare` enqueue ใน `CorrespondenceWorkflowService.syncStatus()` ไปหลัง commit — after-commit pattern ด้วย `triggerRagPrepare()`
|
||||||
|
- ✅ ลบ `backend/src/modules/rag/` ทั้งหมด (audit ไม่พบ import จาก backend/src)
|
||||||
|
- ✅ สร้าง `backend/src/modules/ai/ai-qdrant.service.spec.ts` — regression test สำหรับ `deleteByDocumentPublicId()` (4/4 ผ่าน)
|
||||||
|
- ✅ Code Review Fixes (Session 14+): try-catch after-commit, `createPayloadIndexes()` private, defensive vector size check, `skipRagPrepare` flag
|
||||||
|
- ✅ F5 (Session 15): เพิ่ม `ai-rag-pipeline.integration.spec.ts` — 9 integration tests ครอบคลุม SC-002, SC-003, SC-006, FR-005, jobId dedup

### Legacy Compatibility Note
|
||||||
|
|
||||||
|
- Dashboard RAG page หลักถูกย้ายไปใช้ `/ai/rag/query` + `/ai/rag/jobs/:requestPublicId` แล้ว
|
||||||
|
- Legacy frontend hook `frontend/hooks/use-rag.ts` และ `frontend/components/rag/*` ถูกถอดออกแล้ว หลังย้าย dashboard ไป flow ใหม่
|
||||||
|
- Consumer audit ใน repo ปัจจุบันไม่พบ caller ของ `/rag/status`, `/rag/ingest`, `/rag/vectors`, `/rag/admin/init-collection`
|
||||||
|
- Legacy backend controller/module (`backend/src/modules/rag/rag.controller.ts`, `rag.module.ts`) ถูกถอดออกจาก runtime แล้ว เพื่อให้สอดคล้องกับ feature 234
|
||||||
|
- หากยังมี external callers ของ `/rag/*` อยู่นอก repo ต้อง migrate ไป `/ai/rag/*` ก่อน release ถัดไป

## Summary
|
||||||
|
|
||||||
|
เพิ่ม BGE-M3 embedding + BGE-Reranker-Large + Semantic Chunking เข้า OCR Sidecar, แปลง Qdrant collection `lcbp3_vectors` เป็น Hybrid (1024 dims), และ wire RAG Prep trigger ที่ `syncStatus()` เมื่อเอกสาร Correspondence ผ่าน DRAFT → SUBOWN
|
||||||
|
|
||||||
|
แนวทาง: เพิ่ม `/embed` + `/rerank` ใน `app.py` → refactor `EmbeddingService` + `AiQdrantService` → เพิ่ม `rag-prepare` case ใน `AiBatchProcessor` → hook trigger ใน `CorrespondenceWorkflowService`

|
## Technical Context
|
||||||
|
|
||||||
|
**Language/Version**: Python 3.11 (Sidecar), TypeScript 5.x / NestJS 11 (Backend)
|
||||||
|
**Primary Dependencies**: `FlagEmbedding>=1.2.0` (BGE-M3 + Reranker), `@qdrant/js-client-rest`, BullMQ 5, Ollama
|
||||||
|
**Storage**: Qdrant (vector DB), MariaDB 11.8 (metadata), Redis (job state)
|
||||||
|
**Testing**: Jest (backend unit + integration)
|
||||||
|
**Target Platform**: Docker on Desk-5439 (Windows 10, CPU RAM for BGE-M3)
|
||||||
|
**Project Type**: Web application (backend + sidecar)
|
||||||
|
**Performance Goals**: embed 50-page doc < 5 min; RAG query < 30s end-to-end
|
||||||
|
**Constraints**: BGE-M3 ~2.3GB + Reranker ~1.5GB on CPU RAM; BullMQ concurrency=1 (ai-batch)
|
||||||
|
**Scale/Scope**: Correspondence module only — embed เมื่อ status OUT_OF_DRAFT

## Phase 0: Research Findings
|
||||||
|
|
||||||
|
### R1 — BGE-M3 Python API (FlagEmbedding)
|
||||||
|
|
||||||
|
```python
|
||||||
|
from FlagEmbedding import BGEM3FlagModel
|
||||||
|
model = BGEM3FlagModel('BAAI/bge-m3', use_fp16=False) # CPU mode
|
||||||
|
output = model.encode(['text'], return_dense=True, return_sparse=True)
|
||||||
|
# output['dense_vecs'] → list[float] ขนาด 1024
|
||||||
|
# output['lexical_weights'] → dict {token_id: float}
|
||||||
|
# แปลง sparse: indices = list(keys), values = list(values)
|
||||||
|
```
|
||||||
|
|
||||||
|
### R2 — BGE-Reranker Python API
|
||||||
|
|
||||||
|
```python
|
||||||
|
from FlagEmbedding import FlagReranker
|
||||||
|
reranker = FlagReranker('BAAI/bge-reranker-large', use_fp16=False)
|
||||||
|
scores = reranker.compute_score([['query', chunk] for chunk in chunks])
|
||||||
|
# คืน list[float] — sort descending เพื่อได้ top-N
|
||||||
|
```
|
||||||
|
|
||||||
|
### R3 — Qdrant Hybrid Collection (JS Client)
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
// drop + recreate
|
||||||
|
await client.deleteCollection('lcbp3_vectors');
|
||||||
|
await client.createCollection('lcbp3_vectors', {
|
||||||
|
vectors: { bge_dense: { size: 1024, distance: 'Cosine' } },
|
||||||
|
sparse_vectors: { bge_sparse: {} }
|
||||||
|
});
|
||||||
|
|
||||||
|
// upsert hybrid point
|
||||||
|
await client.upsert('lcbp3_vectors', { points: [{
|
||||||
|
id: uuid,
|
||||||
|
vector: { bge_dense: denseArray, bge_sparse: { indices, values } },
|
||||||
|
payload: { doc_public_id, project_public_id, doc_number, doc_type,
|
||||||
|
status_code, revision_number, subject, document_date,
|
||||||
|
chunk_topic, chunk_index, chunk_text }
|
||||||
|
}]});
|
||||||
|
|
||||||
|
// hybrid search (RRF fusion)
|
||||||
|
await client.query('lcbp3_vectors', {
|
||||||
|
prefetch: [
|
||||||
|
{ query: { indices, values }, using: 'bge_sparse', limit: 20 },
|
||||||
|
{ query: denseArray, using: 'bge_dense', limit: 20 },
|
||||||
|
],
|
||||||
|
query: { fusion: 'rrf' },
|
||||||
|
limit: 15,
|
||||||
|
filter: { must: [{ key: 'project_public_id', match: { value: projectId } }] }
|
||||||
|
});
|
||||||
|
```
|
||||||
|
|
||||||
|
### R4 — OCR Text Cache
|
||||||
|
|
||||||
|
`correspondence_revisions` ไม่มี field เก็บ OCR text โดยตรง — `rag-prepare` job รับ `cachedOcrText?: string` ใน payload; ถ้าไม่มีให้เรียก Sidecar `/ocr` ผ่าน attachment path
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Phase 1: Implementation Design
|
||||||
|
|
||||||
|
### API Contracts
|
||||||
|
|
||||||
|
**Sidecar — POST /embed**
|
||||||
|
```
|
||||||
|
Request: { "text": string }
|
||||||
|
Response: { "dense": number[1024], "sparse": { "indices": number[], "values": number[] } }
|
||||||
|
Auth: X-API-Key header (ค่าเดิมจาก app.py)
|
||||||
|
```
|
||||||
|
|
||||||
|
**Sidecar — POST /rerank**
|
||||||
|
```
|
||||||
|
Request: { "query": string, "chunks": string[] }
|
||||||
|
Response: { "scores": number[], "ranked_indices": number[] }
|
||||||
|
Auth: X-API-Key header
|
||||||
|
```
|
||||||
|
|
||||||
|
**Backend internal type — RagPrepareJobPayload**
|
||||||
|
```typescript
|
||||||
|
interface RagPrepareJobPayload {
|
||||||
|
documentPublicId: string;
|
||||||
|
projectPublicId: string;
|
||||||
|
correspondenceNumber: string;
|
||||||
|
docType: string;
|
||||||
|
statusCode: string;
|
||||||
|
revisionNumber: number;
|
||||||
|
subject: string;
|
||||||
|
documentDate?: string;
|
||||||
|
cachedOcrText?: string;
|
||||||
|
attachmentPath?: string;
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Implementation Phases
|
||||||
|
|
||||||
|
#### Phase A — OCR Sidecar (ไม่กระทบ endpoints เดิม)
|
||||||
|
|
||||||
|
1. `requirements.txt` — เพิ่ม `FlagEmbedding>=1.2.0`
|
||||||
|
2. `app.py` — โหลด BGE-M3 + Reranker ตอน startup (global singleton, CPU)
|
||||||
|
3. `app.py` — เพิ่ม `POST /embed` endpoint
|
||||||
|
4. `app.py` — เพิ่ม `POST /rerank` endpoint
|
||||||
|
|
||||||
|
#### Phase B — AiQdrantService: Hybrid Schema
|
||||||
|
|
||||||
|
5. `AI_VECTOR_SIZE` = 1024 (เดิม 768)
|
||||||
|
6. `ensureCollection()` → drop + recreate Hybrid collection
|
||||||
|
7. `upsert()` → รับ `denseVector` + `sparseVector` + payload ครบ 11 fields (รวม `chunk_text`)
|
||||||
|
8. `search()` / `searchByProject()` → Hybrid query (RRF fusion)
|
||||||
|
9. `deleteByDocumentPublicId()` → filter บน `doc_public_id` payload field
|
||||||
|
|
||||||
|
#### Phase C — EmbeddingService: Semantic Chunking + BGE-M3
|
||||||
|
|
||||||
|
10. `semanticChunkText(ocrText)` method — call typhoon2.5 ด้วย prompt `rag_chunking` จาก `ai_prompts`
|
||||||
|
11. `parseChunkTags(llmOutput)` — parse `<chunk topic="...">` tags, fallback fixed-size
|
||||||
|
12. `embedChunk(text)` — เรียก Sidecar `POST /embed` แทน Ollama nomic
|
||||||
|
|
||||||
|
#### Phase D — AiQueueService + AiBatchProcessor
|
||||||
|
|
||||||
|
13. `ai-queue.service.ts` → `enqueueRagPrepare(payload: RagPrepareJobPayload)`
|
||||||
|
14. `ai-batch.processor.ts` → กำหนด concurrency = 1 ใน `@Processor` และเพิ่ม `case 'rag-prepare': processRagPrepare(data)`
|
||||||
|
15. `processRagPrepare()` — OCR (cached/fallback) → chunk → normalize → embed → delete old → upsert
|
||||||
|
|
||||||
|
#### Phase E — AiRagService: Reranker Integration
|
||||||
|
|
||||||
|
16. `embed(text)` → เรียก Sidecar `/embed` แทน Ollama
|
||||||
|
17. เพิ่ม rerank step หลัง `searchByProject()` → Sidecar `/rerank` → top 3-5 chunks
|
||||||
|
|
||||||
|
#### Phase F — Trigger Hook
|
||||||
|
|
||||||
|
18. `CorrespondenceWorkflowService` → inject `AiQueueService`
|
||||||
|
19. `syncStatus()` → หลัง save ถ้า `targetCode !== 'DRAFT'` → `enqueueRagPrepare()`
|
||||||
|
|
||||||
|
#### Phase G — SQL Delta + Tests
|
||||||
|
|
||||||
|
20. `deltas/2026-06-05-add-rag-chunking-prompt.sql` — INSERT `ai_prompts` (`rag_chunking`)
|
||||||
|
21. Unit tests: `embedding.service.spec.ts` (semantic chunking, fallback)
|
||||||
|
22. Unit tests: `ai-batch.processor.spec.ts` (rag-prepare case)

## User Scenarios & Testing _(mandatory)_
|
||||||
|
|
||||||
|
### User Story 1 — Document Q&A with Accurate Context (Priority: P1)
|
||||||
|
|
||||||
|
ผู้ใช้งานใน Project ต้องการถามคำถามเกี่ยวกับเนื้อหาของเอกสาร Correspondence/RFA ที่อยู่ในระหว่างดำเนินการ (IN_REVIEW ขึ้นไป) โดยระบบจะค้นหาข้อความที่เกี่ยวข้องจากเอกสารทั้งหมดใน Project เดียวกัน แล้วตอบคำถามพร้อมระบุเลขเอกสารและวันที่อ้างอิง
|
||||||
|
|
||||||
|
**Why this priority**: RAG Q&A คือ core value ของ AI integration — ถ้าไม่มี embedding และ retrieval ที่ถูกต้อง Chat Q&A ทำงานไม่ได้
|
||||||
|
|
||||||
|
**Independent Test**: สร้างเอกสาร 2 ฉบับในโปรเจกต์เดียวกัน → submit workflow (IN_REVIEW) → ถามคำถามที่เนื้อหาอยู่ในเอกสาร → ระบบตอบได้พร้อมอ้างอิงเลขเอกสาร
|
||||||
|
|
||||||
|
**Acceptance Scenarios**:
|
||||||
|
|
||||||
|
1. **Given** เอกสาร Correspondence ที่ status = IN_REVIEW ใน Project A, **When** User ถามคำถามที่เนื้อหาอยู่ในเอกสารนั้น, **Then** ระบบตอบได้พร้อมระบุเลขเอกสารและวันที่อ้างอิงภายใน 30 วินาที
|
||||||
|
2. **Given** User ใน Project A ถามคำถาม, **When** เนื้อหาที่เกี่ยวข้องอยู่ใน Project B, **Then** ระบบต้องไม่ดึงข้อมูลจาก Project B มาตอบ (project isolation)
|
||||||
|
3. **Given** เอกสารที่ยัง DRAFT (ยังไม่ submit), **When** User ถามคำถาม, **Then** ระบบต้องไม่นำเนื้อหา DRAFT มาตอบ
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### User Story 2 — Automatic RAG Preparation on Workflow Submit (Priority: P2)
|
||||||
|
|
||||||
|
เมื่อผู้ใช้ submit เอกสาร Correspondence/RFA ผ่าน Workflow Engine (status เปลี่ยนจาก DRAFT เป็น IN_REVIEW/SUBOWN) ระบบจะเตรียม RAG embedding อัตโนมัติในพื้นหลัง โดยไม่กระทบ response time ของการ submit
|
||||||
|
|
||||||
|
**Why this priority**: ถ้าไม่มี auto-trigger embedding User Story 1 จะไม่มีข้อมูลให้ค้นหา
|
||||||
|
|
||||||
|
**Independent Test**: Submit เอกสาร → ตรวจสอบว่า job `rag-prepare` ถูก enqueue ใน BullMQ → รอ job เสร็จ → verify Qdrant มี points ของเอกสารนั้น
|
||||||
|
|
||||||
|
**Acceptance Scenarios**:
|
||||||
|
|
||||||
|
1. **Given** เอกสาร status = DRAFT, **When** User กด Submit workflow, **Then** ระบบ enqueue `rag-prepare` job ใน BullMQ `ai-batch` ภายใน 1 วินาที โดยไม่ block response
|
||||||
|
2. **Given** `rag-prepare` job ทำงาน, **When** เสร็จสมบูรณ์, **Then** Qdrant มี chunks ของเอกสารนั้นพร้อม `project_public_id`, `doc_number`, `status_code`, `chunk_topic` ใน payload
|
||||||
|
3. **Given** เอกสารมี Revision ใหม่ถูก submit, **When** `rag-prepare` ทำงาน, **Then** Qdrant ลบ points เก่าของ revision ก่อนหน้าก่อน upsert points ใหม่
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### User Story 3 — Semantic Chunking for Better Retrieval (Priority: P2)
|
||||||
|
|
||||||
|
เนื้อหาเอกสารแต่ละฉบับถูกแบ่ง chunk ตามความหมาย (Semantic Chunking) โดย LLM ใส่ `<chunk topic="...">` tag ก่อน embed แทนการแบ่งแบบ fixed-size ทำให้ค้นหาได้ตรงหัวข้อมากขึ้น
|
||||||
|
|
||||||
|
**Why this priority**: Semantic chunking ช่วยให้ retrieval accuracy สูงกว่า fixed-size chunking อย่างมีนัยสำคัญ โดยเฉพาะกับเอกสารภาษาไทยที่มีโครงสร้างหัวข้อชัดเจน
|
||||||
|
|
||||||
|
**Independent Test**: embed เอกสารที่มีหลายหัวข้อ → ตรวจสอบ Qdrant payload ว่า `chunk_topic` แต่ละ chunk ตรงกับเนื้อหา → ถามคำถามเฉพาะหัวข้อ → ตรวจสอบว่า reranked chunk ตรงหัวข้อ
|
||||||
|
|
||||||
|
**Acceptance Scenarios**:
|
||||||
|
|
||||||
|
1. **Given** OCR text ของเอกสาร, **When** `rag-prepare` job ทำงาน, **Then** typhoon2.5-np-dms แบ่ง text ออกเป็น chunks พร้อม `<chunk topic="...">` tag อย่างน้อย 1 chunk
|
||||||
|
2. **Given** Semantic chunks ถูกสร้าง, **When** upsert ไป Qdrant, **Then** แต่ละ point มี `chunk_topic` ที่อธิบายหัวข้อของ chunk นั้น
|
||||||
|
3. **Given** ไม่พบ `<chunk>` tag ใน LLM output, **When** fallback triggered, **Then** ระบบ fallback ไปใช้ fixed-size chunking (512 chars) แทนโดยไม่ error
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### User Story 4 — Hybrid Search with Reranking (Priority: P3)
|
||||||
|
|
||||||
|
ระบบใช้ BGE-M3 embedding (Dense 1024 dims + Sparse vectors) และ BGE-Reranker-Large เพื่อให้ retrieval accuracy สูงกว่า dense-only search โดยเฉพาะกับ keyword-heavy queries ภาษาไทย
|
||||||
|
|
||||||
|
**Why this priority**: ปรับปรุง search quality — มี impact แต่ระบบทำงานได้ก่อนจะ implement หากยังใช้ dense-only ก่อน
|
||||||
|
|
||||||
|
**Independent Test**: ส่ง query ที่มีทั้ง semantic และ keyword → ตรวจสอบว่า reranked top-5 มีความเกี่ยวข้องสูงกว่า top-5 จาก dense-only
|
||||||
|
|
||||||
|
**Acceptance Scenarios**:
|
||||||
|
|
||||||
|
1. **Given** User query, **When** ระบบ embed ด้วย BGE-M3, **Then** ได้ทั้ง dense vector (1024 dims) และ sparse vector
|
||||||
|
2. **Given** BGE-M3 vectors, **When** ค้นหาใน Qdrant, **Then** ใช้ Hybrid search (dense + sparse) ได้ top-15 candidates
|
||||||
|
3. **Given** top-15 candidates, **When** ส่งไป BGE-Reranker-Large, **Then** ได้ top 3-5 chunks ที่ reranked score สูงสุดส่งให้ LLM

|
||||||
|
|
||||||
|
### Edge Cases
|
||||||
|
|
||||||
|
- เอกสารที่ไม่มี attachment (ไม่มีไฟล์ PDF) → `rag-prepare` ข้ามการ embed โดยไม่ error แต่ log warning
|
||||||
|
- OCR text ว่างเปล่า / สั้นเกินไป (< 50 chars) → ข้าม semantic chunking + embedding
|
||||||
|
- BGE-M3 Sidecar ไม่พร้อม → `rag-prepare` job fail + retry 3 ครั้ง (ADR-008)
|
||||||
|
- Qdrant ไม่พร้อม → `rag-prepare` job fail + retry
|
||||||
|
- เอกสาร REJECTED กลับเป็น DRAFT → ไม่ trigger `rag-prepare` ซ้ำ (status ลดลง ไม่ใช่ขึ้น)
|
||||||
|
- หลาย users submit พร้อมกัน → idempotency key ป้องกัน duplicate `rag-prepare` jobs

## Requirements _(mandatory)_
|
||||||
|
|
||||||
|
### Functional Requirements
|
||||||
|
|
||||||
|
**OCR Sidecar (app.py)**
|
||||||
|
|
||||||
|
- **FR-001**: Sidecar MUST expose `POST /embed` endpoint รับ `{"text": string}` และคืน `{"dense": number[], "sparse": {indices: number[], values: number[]}}`
|
||||||
|
- **FR-002**: Sidecar MUST expose `POST /rerank` endpoint รับ `{"query": string, "chunks": string[]}` และคืน scores เรียงลำดับ
|
||||||
|
- **FR-003**: BGE-M3 และ BGE-Reranker-Large MUST โหลดบน CPU RAM เมื่อ Sidecar start (ไม่ใช้ VRAM)
|
||||||
|
|
||||||
|
**Semantic Chunking**
|
||||||
|
|
||||||
|
- **FR-004**: ระบบ MUST ใช้ typhoon2.5-np-dms วิเคราะห์ OCR text และใส่ `<chunk topic="...">` tag ก่อน embed โดยดึง prompt จาก `ai_prompts` ที่ `prompt_type = 'rag_chunking'` (ADR-029)
|
||||||
|
- **FR-004a**: ระบบ MUST seed `ai_prompts` record สำหรับ `prompt_type = 'rag_chunking'` ผ่าน SQL delta (ADR-009) พร้อม placeholder `{{ocr_text}}`
|
||||||
|
- **FR-005**: ระบบ MUST fallback ไปใช้ fixed-size chunking (512 chars / 64 overlap) หากไม่พบ `<chunk>` tag ใน LLM output
|
||||||
|
- **FR-006**: chunk topic MUST บันทึกไว้ใน Qdrant payload field `chunk_topic`
|
||||||
|
|
||||||
|
**Qdrant Collection**
|
||||||
|
|
||||||
|
- **FR-007**: Qdrant collection `lcbp3_vectors` MUST ถูก drop + recreate ใหม่รองรับ Hybrid search (Dense 1024 dims + Sparse SPLADE) — collection เดิม (768 dims dense-only) จะถูกแทนที่ทันทีที่ feature นี้ deploy
|
||||||
|
- **FR-008**: Qdrant payload MUST มีครบ 11 fields: `doc_public_id`, `project_public_id`, `doc_number`, `doc_type`, `status_code`, `revision_number`, `subject`, `document_date`, `chunk_topic`, `chunk_index`, `chunk_text`
|
||||||
|
- **FR-009**: Qdrant MUST มี payload index บน `project_public_id` (tenant), `doc_public_id`, `status_code`, `doc_type`
|
||||||
|
- **FR-009a**: `AI_VECTOR_SIZE` constant MUST เปลี่ยนจาก `768` เป็น `1024` และ collection name constant คงเป็น `lcbp3_vectors`
|
||||||
|
|
||||||
|
**RAG Prepare Pipeline**
|
||||||
|
|
||||||
|
- **FR-010**: ระบบ MUST enqueue `rag-prepare` job ใน `ai-batch` queue เมื่อ `CorrespondenceRevision` status เปลี่ยนจาก DRAFT เป็น IN_REVIEW (SUBOWN) โดย job payload ต้องรวม `cachedOcrText` ถ้ามีใน DB; หากไม่มี job MUST เรียก OCR sidecar ใหม่โดยดึง PDF attachment จาก storage
|
||||||
|
- **FR-011**: `rag-prepare` job MUST ลบ Qdrant points เก่าของ `doc_public_id` ก่อน upsert ใหม่เสมอ (delete + re-embed)
|
||||||
|
- **FR-012**: `rag-prepare` job MUST ไม่ block workflow submission response
|
||||||
|
|
||||||
|
**RAG Query Pipeline**
|
||||||
|
|
||||||
|
- **FR-013**: RAG query MUST embed คำถามด้วย BGE-M3 ผ่าน Sidecar `/embed`
|
||||||
|
- **FR-014**: RAG query MUST ค้นหา Qdrant ด้วย Hybrid search topK=15 กรอง `project_public_id` เป็น mandatory
|
||||||
|
- **FR-015**: RAG query MUST rerank ด้วย BGE-Reranker ผ่าน Sidecar `/rerank` เพื่อได้ top 3-5 chunks ก่อนส่ง LLM
|
||||||
|
|
||||||
|
### Key Entities
|
||||||
|
|
||||||
|
- **EmbeddedChunk**: ข้อมูลที่เก็บใน Qdrant — `doc_public_id`, `project_public_id`, `doc_number`, `doc_type`, `status_code`, `revision_number`, `subject`, `document_date`, `chunk_topic`, `chunk_index`, `chunk_text`
|
||||||
|
- **RagPrepareJob**: BullMQ job payload — `documentPublicId`, `projectPublicId`, `correspondenceNumber`, `docType`, `statusCode`, `revisionNumber`, `subject`, `documentDate`, `ocrText`
|
||||||
|
- **RagQueryJob**: BullMQ job payload — `requestPublicId`, `userPublicId`, `projectPublicId`, `query`
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Success Criteria _(mandatory)_
|
||||||
|
|
||||||
|
### Measurable Outcomes
|
||||||
|
|
||||||
|
- **SC-001**: เอกสารที่ submit workflow ถูก embed และพร้อมค้นหาใน Qdrant ภายใน 5 นาทีหลัง submit สำเร็จ
|
||||||
|
- **SC-002**: Chat Q&A ตอบคำถามที่เนื้อหาอยู่ในเอกสาร IN_REVIEW ขึ้นไปได้ถูกต้องอย่างน้อย 80% ของกรณีทดสอบ
|
||||||
|
- **SC-003**: ไม่มีข้อมูลจาก Project อื่นรั่วไหลมาในคำตอบ (0% cross-project leak)
|
||||||
|
- **SC-004**: `rag-prepare` job ไม่ delay workflow submission response เกิน 500ms
|
||||||
|
- **SC-005**: ระบบรองรับการ embed เอกสารขนาดสูงสุด 50 หน้าโดยไม่ timeout
|
||||||
|
- **SC-006**: เมื่อมี revision ใหม่ ข้อมูลเก่าในระบบค้นหาถูกแทนที่ด้วยข้อมูลใหม่ทั้งหมด (0 stale chunks)

## Clarifications
|
||||||
|
|
||||||
|
### Session 2026-06-05
|
||||||
|
|
||||||
|
- Q: OCR text source สำหรับ `rag-prepare` job → A: ใช้ cached OCR text ถ้ามี, fallback เรียก OCR sidecar ใหม่ถ้าไม่มี (Option C)
|
||||||
|
- Q: Qdrant collection migration strategy → A: ใช้ชื่อ collection เดิม `lcbp3_vectors` แต่ drop + recreate schema ใหม่ (1024 dims Hybrid) ทันที (Option C)
|
||||||
|
- Q: Semantic Chunking prompt type ใน `ai_prompts` → A: เพิ่ม prompt type ใหม่ `rag_chunking` แยกต่างหาก (Option A)
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Assumptions
|
||||||
|
|
||||||
|
- BGE-M3 (BAAI/bge-m3 ~2.3GB) และ BGE-Reranker-Large (~1.5GB) รันบน CPU RAM บน Desk-5439 ได้โดยไม่กระทบ VRAM ของ Ollama
|
||||||
|
- OCR text อาจมีหรือไม่มีใน DB — `rag-prepare` job จัดการทั้งสองกรณี (cached + fallback OCR)
|
||||||
|
- Qdrant collection `lcbp3_vectors` เดิม (768 dims) จะถูก drop + recreate เป็น Hybrid (1024 dims) เมื่อ deploy — ข้อมูล vector เดิมทั้งหมดจะหายไป ซึ่งยอมรับได้เพราะยังไม่มีข้อมูล production ที่ embed ด้วยระบบใหม่
|
||||||
|
- Sidecar service (port 8765) ยังคงใช้ container เดิม เพียงเพิ่ม endpoints ใหม่

||||||
|
|
||||||
|
**Input**: Design documents from `specs/200-fullstacks/234-rag-pipeline-enhancements/`
|
||||||
|
**Prerequisites**: plan.md ✅, spec.md ✅
|
||||||
|
**Branch**: `234-rag-pipeline-enhancements`
|
||||||
|
|
||||||
|
## Format: `[ID] [P?] [Story] Description`
|
||||||
|
|
||||||
|
- **[P]**: Can run in parallel (different files, no dependencies)

||||||
|
- **[Story]**: US1=Chat Q&A, US2=Auto RAG Trigger, US3=Semantic Chunking, US4=Hybrid Search
|
||||||

|
||||||
|
|
||||||
|
## Phase 1: Setup (Shared Infrastructure)
|
||||||
|
|
||||||
|
**Purpose**: เพิ่ม dependency และ SQL delta ที่จำเป็นสำหรับทุก story
|
||||||
|
|
||||||
|
- [X] T001 [P] เพิ่ม `FlagEmbedding>=1.2.0` ใน `specs/04-Infrastructure-OPS/04-00-docker-compose/Desk-5439/ocr-sidecar/requirements.txt`
|
||||||
|
- [X] T002 [P] สร้าง SQL delta `specs/03-Data-and-Storage/deltas/2026-06-05-add-rag-chunking-prompt.sql` — INSERT `ai_prompts` (`prompt_type='rag_chunking'`, placeholder `{{ocr_text}}`)
|
||||||
|
|
||||||
|
**Checkpoint**: dependencies + SQL delta พร้อม — สามารถเริ่ม Phase 2 ได้
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Phase 2: Foundational (Blocking Prerequisites)
|
||||||
|
|
||||||
|
**Purpose**: OCR Sidecar + AiQdrantService ใหม่ — ทุก story ต้องพึ่งพิงสองส่วนนี้
|
||||||
|
|
||||||
|
⚠️ **CRITICAL**: Phase 3+ ทั้งหมดต้องรอ Phase 2 เสร็จก่อน
|
||||||
|
|
||||||
|
### 2A — OCR Sidecar: BGE-M3 + Reranker endpoints
|
||||||
|
|
||||||
|
- [X] T003 โหลด `BGEM3FlagModel` และ `FlagReranker` เป็น global singleton ตอน startup ใน `specs/04-Infrastructure-OPS/04-00-docker-compose/Desk-5439/ocr-sidecar/app.py` (CPU mode, `use_fp16=False`)
|
||||||
|
- [X] T004 [P] เพิ่ม `POST /embed` endpoint ใน `app.py` — รับ `{"text": string}` คืน `{"dense": list[float], "sparse": {"indices": list[int], "values": list[float]}}`
|
||||||
|
- [X] T005 [P] เพิ่ม `POST /rerank` endpoint ใน `app.py` — รับ `{"query": string, "chunks": list[str]}` คืน `{"scores": list[float], "ranked_indices": list[int]}`
|
||||||
|
|
||||||
|
### 2B — AiQdrantService: Hybrid Schema
|
||||||
|
|
||||||
|
- [X] T006 แก้ `AI_VECTOR_SIZE = 1024` (เดิม 768) ใน `backend/src/modules/ai/qdrant.service.ts`
|
||||||
|
- [X] T007 แก้ `ensureCollection()` → drop collection เก่าก่อน แล้ว recreate เป็น Hybrid (`bge_dense` size=1024 + `bge_sparse`) ใน `backend/src/modules/ai/qdrant.service.ts`
|
||||||
|
- [X] T008 แก้ `upsert()` → รับ interface ใหม่ที่มี `denseVector: number[]`, `sparseVector: {indices: number[], values: number[]}`, และ payload ครบ 11 fields (`doc_public_id`, `project_public_id`, `doc_number`, `doc_type`, `status_code`, `revision_number`, `subject`, `document_date`, `chunk_topic`, `chunk_index`, `chunk_text`) ใน `backend/src/modules/ai/qdrant.service.ts`
|
||||||
|
- [X] T009 แก้ `deleteByDocumentPublicId()` → filter บน payload field `doc_public_id` (ไม่ใช่ point id) ใน `backend/src/modules/ai/qdrant.service.ts`
|
||||||
|
- [X] T010 เพิ่ม payload indexes สำหรับ `doc_public_id`, `status_code`, `doc_type` ใน `ensureCollection()` ใน `backend/src/modules/ai/qdrant.service.ts`
|
||||||
|
|
||||||
|
**Checkpoint**: Sidecar `/embed` + `/rerank` พร้อม; Qdrant collection ใหม่พร้อม — เริ่ม Phase 3+ ได้
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Phase 3: User Story 1 — Document Q&A with Accurate Context (P1) 🎯 MVP
|
||||||
|
|
||||||
|
**Goal**: Chat Q&A ใช้ BGE-M3 embed query + Hybrid search + Reranker ก่อนส่ง LLM
|
||||||
|
|
||||||
|
**Independent Test**: ส่ง RAG query → ตรวจสอบ Sidecar `/embed` ถูกเรียก → Qdrant Hybrid search → `/rerank` ถูกเรียก → LLM ตอบพร้อม citation
|
||||||
|
|
||||||
|
### Tests for User Story 1
|
||||||
|
|
||||||
|
- [X] T011 [P] [US1] เขียน unit test `backend/src/modules/ai/ai-rag.service.spec.ts` — mock Sidecar `/embed` และ `/rerank`; ตรวจสอบว่า `processQuery()` เรียก embed ก่อน search ก่อน rerank
|
||||||
|
|
||||||
|
### Implementation for User Story 1
|
||||||
|
|
||||||
|
- [X] T012 [US1] เพิ่ม method `embedViaSidecar(text: string)` ใน `backend/src/modules/ai/services/ocr.service.ts` — POST Sidecar `/embed`, คืน `{dense, sparse}`
|
||||||
|
- [X] T013 [US1] แก้ `search()` / `searchByProject()` ใน `backend/src/modules/ai/qdrant.service.ts` → ใช้ Hybrid query (RRF fusion) แทน dense-only, รับ `denseVector` + `sparseVector`
|
||||||
|
- [X] T014 [US1] เพิ่ม method `rerankViaSidecar(query: string, chunks: string[])` ใน `backend/src/modules/ai/services/ocr.service.ts` — POST Sidecar `/rerank`
|
||||||
|
- [X] T015 [US1] แก้ `processQuery()` ใน `backend/src/modules/ai/ai-rag.service.ts`:
|
||||||
|
- เรียก `embedViaSidecar()` แทน `ollamaService.generateEmbedding()`
|
||||||
|
- เรียก `searchByProject()` ด้วย Hybrid vectors, topK=15
|
||||||
|
- เรียก `rerankViaSidecar()` → เลือก top 3-5 chunks
|
||||||
|
- ประกอบ context จาก payload ใหม่ (`chunk_text`, `doc_number`, `document_date`, `status_code`)
|
||||||
|
|
||||||
|
**Checkpoint**: US1 — RAG query ทำงานครบ pipeline ใหม่
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Phase 4: User Story 2 — Automatic RAG Preparation on Workflow Submit (P2)
|
||||||
|
|
||||||
|
**Goal**: submit Correspondence → trigger `rag-prepare` job อัตโนมัติ ไม่ block response
|
||||||
|
|
||||||
|
**Independent Test**: Submit workflow → ตรวจ BullMQ `ai-batch` queue มี `rag-prepare` job → job เสร็จ → Qdrant มี points ของเอกสาร
|
||||||
|
|
||||||
|
### Tests for User Story 2
|
||||||
|
|
||||||
|
- [X] T016 [P] [US2] เขียน unit test `backend/src/modules/ai/processors/ai-batch.processor.spec.ts` — ตรวจสอบ `case 'rag-prepare'` ถูก dispatch และเรียก OCR/embed/upsert ตามลำดับ
|
||||||
|
- [X] T017 [P] [US2] เขียน unit test `backend/src/modules/correspondence/correspondence-workflow.service.spec.ts` — ตรวจสอบว่า `syncStatus()` เรียก `enqueueRagPrepare()` เมื่อ targetCode ≠ 'DRAFT'
|
||||||
|
|
||||||
|
### Implementation for User Story 2
|
||||||
|
|
||||||
|
- [X] T018 [US2] เพิ่ม interface `RagPrepareJobPayload` และ method `enqueueRagPrepare(payload)` ใน `backend/src/modules/ai/ai-queue.service.ts`
|
||||||
|
- [X] T019 [US2] เพิ่ม `case 'rag-prepare':` ใน `process()` ของ `backend/src/modules/ai/processors/ai-batch.processor.ts` — dispatch ไป `processRagPrepare(data)`
|
||||||
|
- [X] T019a [US2] ตรวจสอบและตั้งค่าให้ `ai-batch` Queue Processor มี `concurrency: 1` ใน `@Processor` decorator เพื่อป้องกัน VRAM overflow ตาม ADR-035
|
||||||
|
- [X] T020a [US2] implement OCR text resolution ใน `processRagPrepare()` ใน `ai-batch.processor.ts`: ถ้า `cachedOcrText` มีให้ใช้เลย; ถ้าไม่มีและมี `attachmentPath` เรียก `OcrService.extractText(attachmentPath)`; ถ้าไม่มีทั้งคู่ → `this.logger.warn('rag-prepare: ไม่มี OCR text และไม่มี attachment path')` แล้ว return early
|
||||||
|
- [X] T020b [US2] implement skip-guard ใน `processRagPrepare()`: ถ้า `ocrText.trim().length < 50` → `this.logger.warn('rag-prepare: OCR text สั้นเกินไป — skip embedding')` แล้ว return early (ไม่ error, ไม่ fail job)
|
||||||
|
- [X] T020c [US2] implement embed + upsert pipeline ใน `processRagPrepare()`: เรียก `EmbeddingService.embedDocument()` (refactor ใน US3) → เรียก `AiQdrantService.deleteByDocumentPublicId(projectPublicId, documentPublicId)` → เรียก `AiQdrantService.upsert()` ด้วย chunks + payload ครบ 11 fields รวม `status_code` จาก `data.statusCode`
|
||||||
|
- [X] T021 [US2] inject `AiQueueService` เข้า `CorrespondenceWorkflowService` constructor ใน `backend/src/modules/correspondence/correspondence-workflow.service.ts`
|
||||||
|
- [X] T022 [US2] แก้ `syncStatus()` ใน `correspondence-workflow.service.ts` — หลัง save ถ้า `targetCode !== 'DRAFT'` → เรียก `aiQueueService.enqueueRagPrepare()` แบบ fire-and-forget พร้อมข้อมูลจาก `revision` + `correspondence`
|
||||||
|
- [X] T023 [US2] อัปเดต `CorrespondenceModule` imports ให้ `CorrespondenceWorkflowService` เข้าถึง `AiQueueService` ได้ ใน `backend/src/modules/correspondence/correspondence.module.ts`
|
||||||
|
|
||||||
|
**Checkpoint**: US2 — submit → BullMQ job → Qdrant embed ทำงานครบ
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Phase 5: User Story 3 — Semantic Chunking (P2)
|
||||||
|
|
||||||
|
**Goal**: `EmbeddingService` ใช้ Semantic Chunking ด้วย typhoon2.5 + prompt `rag_chunking` แทน fixed-size
|
||||||
|
|
||||||
|
**Independent Test**: embed เอกสาร → ตรวจ Qdrant points มี `chunk_topic` ที่ไม่ว่างเปล่า → fallback: ลบ `<chunk>` tag ออกจาก LLM output → ตรวจว่าใช้ fixed-size แทน
|
||||||
|
|
||||||
|
### Tests for User Story 3
|
||||||
|
|
||||||
|
- [X] T024 [P] [US3] เขียน unit test `backend/src/modules/ai/services/embedding.service.spec.ts`:
|
||||||
|
- `semanticChunkText()` — mock LLM output พร้อม `<chunk>` tag → ตรวจ parse ถูกต้อง
|
||||||
|
- fallback case — LLM output ไม่มี `<chunk>` tag → ตรวจใช้ fixed-size chunking
|
||||||
|
|
||||||
|
### Implementation for User Story 3
|
||||||
|
|
||||||
|
- [X] T025 [US3] เพิ่ม method `semanticChunkText(ocrText: string)` ใน `backend/src/modules/ai/services/embedding.service.ts`:
|
||||||
|
- โหลด prompt จาก `ai_prompts` (`prompt_type='rag_chunking'`) ผ่าน `PromptService` หรือ query โดยตรง
|
||||||
|
- เรียก `OllamaService` ด้วย typhoon2.5-np-dms + prompt + `ocrText`
|
||||||
|
- คืน LLM output string
|
||||||
|
- [X] T026 [US3] เพิ่ม method `parseChunkTags(llmOutput: string)` ใน `embedding.service.ts`:
|
||||||
|
- parse `<chunk topic="...">...</chunk>` tags ด้วย regex
|
||||||
|
- ถ้าไม่มี tag → fallback `fixedSizeChunk(ocrText, 512, 64)`
|
||||||
|
- คืน `Array<{topic: string, text: string}>`
|
||||||
|
- [X] T027 [US3] แก้ `embedDocument()` ใน `embedding.service.ts`:
|
||||||
|
- เรียก `semanticChunkText()` → `parseChunkTags()`
|
||||||
|
- สำหรับแต่ละ chunk: เรียก `OcrService.embedViaSidecar(chunk.text)` → ได้ `{dense, sparse}`
|
||||||
|
- upsert ผ่าน `AiQdrantService.upsert()` ด้วย payload ครบ 11 fields (รวม `chunk_topic` และ `chunk_text`)
|
||||||
|
|
||||||
|
**Checkpoint**: US3 — Semantic Chunking พร้อม; US2 `processRagPrepare()` ใช้ path ใหม่นี้โดยอัตโนมัติ
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Phase 6: User Story 4 — Hybrid Search with Reranking (P3)
|
||||||
|
|
||||||
|
**Goal**: ตรวจสอบว่า Hybrid search (RRF) ทำงานถูกต้องใน production-like scenario
|
||||||
|
|
||||||
|
**Independent Test**: ส่ง query ที่มี keyword เฉพาะ → ตรวจสอบ sparse vector ถูกส่งไป Qdrant → reranked top-5 scores มีค่า > dense-only baseline
|
||||||
|
|
||||||
|
### Implementation for User Story 4
|
||||||
|
|
||||||
|
- [X] T028 [US4] เพิ่ม payload index สำหรับ `doc_type` และ `status_code` ใน Qdrant `ensureCollection()` ถ้ายังไม่มี (ต่อจาก T010) ใน `backend/src/modules/ai/qdrant.service.ts`
|
||||||
|
- [X] T029 [US4] ตรวจสอบ `searchByProject()` ใน `qdrant.service.ts` รองรับ optional `statusFilter` parameter สำหรับกรณีที่ต้องการ approved-only ในอนาคต
|
||||||
|
- [X] T030 [US4] เพิ่ม logging ใน `processQuery()` ใน `ai-rag.service.ts` — log จำนวน candidates ก่อน/หลัง rerank และ top scores (ใช้ NestJS `Logger`, ไม่ใช้ `console.log`)
|
||||||
|
|
||||||
|
**Checkpoint**: US4 — Hybrid search + reranking verified
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Phase 7: Polish & Cross-Cutting Concerns
|
||||||
|
|
||||||
|
- [X] T031 [P] deprecate หรือ remove `backend/src/modules/rag/qdrant.service.ts` (เก่า — replaced โดย `ai/qdrant.service.ts`) หลังตรวจสอบว่าไม่มี import อื่นใช้อยู่
|
||||||
|
- [X] T032 [P] อัปเดต `backend/src/modules/ai/ai.module.ts` imports/providers ถ้ามีการเปลี่ยนแปลง dependencies ใหม่
|
||||||
|
- [X] T033 อัปเดต ADR-035 `Implementation Status` table — Flow 2B และ Flow 4 เป็น ✅ ใน `specs/06-Decision-Records/ADR-035-ai-pipeline-flow-architecture.md`
|
||||||
|
- [X] T034 [P] ตรวจสอบ TypeScript strict — ไม่มี `any`, ไม่มี `console.log` ใน files ที่แก้ไขทั้งหมด
|
||||||
|
|
||||||

|
## Dependencies & Execution Order
|
||||||
|
|
||||||
|
### Phase Dependencies
|
||||||
|
|
||||||
|
- **Phase 1** (Setup): เริ่มได้ทันที — ขนานกันได้
|
||||||
|
- **Phase 2** (Foundational): ต้องรอ Phase 1 — blocks Phase 3+
|
||||||
|
- **Phase 3** (US1 — Chat Q&A): ต้องรอ Phase 2 — T012-T015 ต้องการ Sidecar + Qdrant ใหม่
|
||||||
|
- **Phase 4** (US2 — RAG Trigger): ต้องรอ Phase 2 — T018-T023 ต้องการ Qdrant ใหม่
|
||||||
|
- **Phase 5** (US3 — Semantic Chunking): ต้องรอ Phase 2 + T018 (ใช้ `enqueueRagPrepare` type)
|
||||||
|
- **Phase 6** (US4 — Hybrid): ต้องรอ Phase 3 (ใช้ `searchByProject` ใหม่)
|
||||||
|
- **Phase 7** (Polish): ต้องรอ Phase 3-6 ครบ
|
||||||
|
|
||||||
|
### User Story Dependencies
|
||||||
|
|
||||||
|
- **US1** ⬅️ Phase 2 (Sidecar /embed, /rerank; Qdrant Hybrid)
|
||||||
|
- **US2** ⬅️ Phase 2 (Qdrant Hybrid) + T018 type definition
|
||||||
|
- **US3** ⬅️ Phase 2 + T018 + SQL delta T002
|
||||||
|
- **US4** ⬅️ US1 (T013 searchByProject Hybrid)
|
||||||
|
|
||||||
|
### Parallel Opportunities
|
||||||
|
|
||||||
|
- T001 + T002 ขนานกัน (Phase 1)
|
||||||
|
- T003 (Sidecar init) → T004 + T005 ขนานกัน
|
||||||
|
- T006-T010 ขนานกันได้ (ไฟล์เดียวกันแต่ methods ต่างกัน — ทำตามลำดับเพื่อความปลอดภัย)
|
||||||
|
- T011 + T016 + T017 + T024 ขนานกัน (เขียน tests คนละไฟล์)
|
||||||
|
- T012 + T014 ขนานกัน (methods ต่างกันใน ocr.service.ts)
|
||||||
|
- T018 + T025 ขนานกัน (คนละไฟล์)
|
||||||

## Implementation Strategy
|
||||||
|
|
||||||
|
### MVP First (User Story 1 + 2)
|
||||||
|
|
||||||
|
1. Phase 1: Setup (T001-T002)
|
||||||
|
2. Phase 2: Foundational — Sidecar + Qdrant (T003-T010)
|
||||||
|
3. Phase 3: US1 Chat Q&A (T011-T015) → **ทดสอบ RAG query ทำงาน**
|
||||||
|
4. Phase 4: US2 RAG Trigger (T016-T023) → **ทดสอบ submit → embed**
|
||||||
|
5. **STOP & VALIDATE**: ระบบ embed + query ใหม่ทำงานครบ end-to-end
|
||||||
|
6. Deploy รอบแรก
|
||||||
|
|
||||||
|
### Incremental Addition
|
||||||
|
|
||||||
|
7. Phase 5: US3 Semantic Chunking → re-embed เอกสารที่มี
|
||||||
|
8. Phase 6: US4 Hybrid verification
|
||||||
|
9. Phase 7: Polish + deprecate code เก่า

## Notes
|
||||||
|
|
||||||
|
- `[P]` = ขนานกันได้ (different files หรือ independent methods)
|
||||||
|
- ทุก task ต้องไม่มี `any` type และไม่มี `console.log` (ใช้ NestJS `Logger`)
|
||||||
|
- Qdrant drop collection เกิดขึ้นตอน `ensureCollection()` ถูกเรียกครั้งแรกหลัง deploy — Chat Q&A จะ return empty ชั่วคราวจนกว่า documents จะถูก re-embed
|
||||||
|
- commit message format: `feat(ai): <description>` หรือ `refactor(ai): <description>`
