[CLAUDE] Docs: setup RAG Framework v1.3 governance + eval framework

- docs/governance/README.md: Path B delegation stub → AI_INFRA canonical
  Phase/BC vocabulary documented (9 phase + 10 BC SOLUTION_ERP-specific)
- .claude/rag.json: add _decision_log block (10 rationale entries) +
  add .claude/agents/**/*.md to corpus_paths (fix Case D harvest gap)
- eval/evaluator.md: inline executor spec v1.0 (Spec A strict)
- eval/golden-set-solution_erp.jsonl: 14-entry golden set v1.1
  (5 gotcha + 3 pattern + 3 decision + 3 negative)
- eval/runs/2026-05-26-baseline-v1.0-failed.json: v1.0 attempt
  recall@5=0.455 FAIL — root cause diagnosis Case A/C/D
- eval/runs/2026-05-26-baseline-v1.1-pending.json: v1.1 attempt
  pending CLI restart for accurate numbers
- eval/trial-state-lock.json: 2-section split (quality_gate +
  drift_monitor) per v1.3 §6.2, 4-week milestones 2026-05-26 → 2026-06-23

CRITICAL lesson: bootstrap.py --project flag overrides collection name only.
Use --config D:\...\SOLUTION_ERP\.claude\rag.json for correct project root.
Old projects.json had root_path=AI_INFRA for solution_erp (Anti #24) — FIXED.

+## Delegation to AI_INFRA canonical
+
+SOLUTION_ERP adopts RAG Framework v1.3 via **Path B delegation stub** — deferring to AI_INFRA canonical docs.
+
+| Doc | Path |
+|---|---|
+| **Comprehensive guide (v1.3)** | `D:\Dropbox\CONG_VIEC\AI_INFRA\docs\governance\RAG-FRAMEWORK-V1.3-SETUP-GUIDE.md` |

+## SOLUTION_ERP project-specific config
+
+### Phase + BC vocabulary
+
+**Phase enum (project-specific):**
+- `phase-1-foundation` — Core schema + Identity + Master (Mig 1-11)
+- `phase-2-contract` — Contract workflow 9-phase (Mig 1-11)
+- `phase-3-pe-v1` — PurchaseEvaluation V1 flat approval (Mig 12-15)
+- `phase-4-budget` — Budget module 3-panel (Mig 14)
+- `phase-5-forms` — FormTemplate + Clause engine (Mig 4)
+- `phase-6-pe-v2` — PE V2 dynamic approval workflow (Mig 22-26)
+- `phase-7-contract-v2` — Contract V2 mirror PE pattern (Mig 27-33)
+- `phase-8-admin-ops` — CatalogManager role + admin ops (Plan CA)
+- `phase-9-uat` — UAT + production hardening (current)
+
+**BC (bounded-context) enum (project-specific):**
+- `bc-contract` — Contract workflow + ContractApprovals
+- `bc-pe` — PurchaseEvaluation + PEDeptOpinions + PELevelOpinions
+- `bc-budget` — Budget + BudgetItems
+- `bc-identity` — User + Role + Permission + MenuItem
+- `bc-master` — Supplier + Project + Department
+- `bc-forms` — FormTemplate + FormClause
+- `bc-notification` — Notification + SignalR
+- `bc-workflow` — ApprovalWorkflow + Steps + Levels (cross-module)
+- `bc-cicd` — Gitea Actions + NSSM runner + IIS deploy
+- `bc-agent` — Sub-agent memory + skills + governance
+
+### Anatomy gate threshold
+
+**6/6 STRICT** per v1.3 §5.2 default — corpus 11,922 chunks mature enough.
+
+### Spec A vs B
+
+**Spec A — Strict** — SOLUTION_ERP chunks canonical + finite scope (gotchas, patterns, decisions) → strict retrieval test appropriate.

+## Anti-pattern watch (SOLUTION_ERP-specific)
+
+- **Anti #23 source_path absolute path leak** — chunks contain `D:\Dropbox\...` Windows absolute path. Noted — fix in next re-bootstrap run.
+- **Anti #24 registry drift +321%** — `projects.json` says 2830, Qdrant LIVE 11,922. Intentional defer — document in trial-lock `_baseline_note`. Re-bootstrap align khi Phase 9 UAT ổn định.

+# Eval Executor Spec — SOLUTION_ERP
+
+> **Version:** v1.0 (2026-05-26)
+> **Spec:** A — Strict (expected chunk must appear in top-5, rerank ≥ 0.7 = confident hit)
+> **Framework:** RAG v1.3 §6.3 — Spec A vs B locked BEFORE first baseline
+> **Companion:** `RAG-FRAMEWORK-V1.3-SETUP-GUIDE.md` §6
+

+
+## Execution protocol
+
+### 1. Run search_memory for each query
+
+```python
+# Fire all 14 queries in parallel (MCP tool)
+mcp__rag-unified__search_memory(
+    query=<query>,
+    scope="self",      # project = solution_erp
+    top_k=5,
+    use_rerank=True
+)
+```
+
+### 2. Scoring per query (Spec A — Strict)
+
+| Hit condition | Score |
+|---|---|
+| Expected source_path appears in top-5 AND rerank ≥ 0.7 | ✅ HIT |
+| Expected source_path appears in top-5 BUT rerank < 0.7 | ✗ MISS (Case A suspect) |
+| Expected source_path NOT in top-5 | ✗ MISS — classify Case B/C/D |
+| Negative query: 0 results OR all rerank < 0.7 | ✅ CORRECT EXCLUSION |
+
+### 3. recall@5 calculation
+
+```
+recall@5 = hits / positive_queries
+positive_queries = 11 (q01-q11, excluding 3 negative q12-q14)
+gate_threshold = 0.7 → must hit ≥ 8/11
+```
+
+### 4. Case classification for failures
+
+Per v1.3 §10:
+- **Case A:** chunk in top-5 but rerank low → threshold calibration
+- **Case B:** chunk NOT top-5 but IS top-20 → retrieval param tuning
+- **Case C:** chunk NOT top-20 but verbatim phrase IS in corpus → rerank context-density bias
+- **Case D:** verbatim phrase NOT in corpus → harvest gap
+
+### 5. Output format
+
+Save to `eval/runs/YYYY-MM-DD-baseline-vN.N.json`:
+
+```json
+{
+  "run_date": "YYYY-MM-DD",
+  "golden_set_version": "vN.N",
+  "spec": "A",
+  "results": [
+    {

+  "recall_at_5": 0.000,
+  "avg_top1_rerank": 0.000,
+  "pass_gate": true/false
+}
+```
+
+---
+
+## Golden set file
+
+`eval/golden-set-solution_erp.jsonl` — 14 entries (immutable during trial period)
+
+**Mutation rules:**
+- ❌ DO NOT rephrase query mid-trial (Anti #11)
+- ❌ DO NOT modify expected_source_paths post-baseline (Anti #12)
+- ✅ Version bump v1.0 → v1.1 OK WITH lock of prior version + transparent re-author (AI_INFRA lesson §3.5)
+
+---
+
+## Weekly Friday execution
+
+1. Fire 14 queries SAME (no modification)
+2. Score → recall@5 + avg_rerank
+3. Compare vs `eval/trial-state-lock.json` baseline
+4. Check chunk_count drift (Qdrant LIVE vs baseline)
+5. Update lock file milestone status
+6. If recall < gate → apply §15.1 4-cause triage
