[CLAUDE] Docs: Session 26 FINAL wrap — 2 architectural decisions + RAG indexing verify

Anh chốt 2 decisions cuối session sau commit bf93abd:

1. Approach B distributed RAG bootstrap — em main SOLUTION_ERP chỉ build
   INFRASTRUCTURE + DOCS, KHÔNG bootstrap data hộ 4 dự án khác. Em main
   NamGroup/DH Y Dược/Ashico/Vipix tự bootstrap khi anh mở session project đó.
   Lý do: Cognition "writes single-threaded" boundary + sensitivity per project
   + self-ownership re-bootstrap + knowledge propagation natural qua shared_global.

2. Option 4a manual PowerShell scripts thay Phase 6b Task Scheduler auto-start.
   Anh OWN control qua aliases rag-start/rag-stop/rag-status/rag-dashboard
   + Qdrant dashboard built-in FREE http://localhost:6333/dashboard.

Bug fix bootstrap.py glob extra_corpus — import glob.glob(recursive=True)
thay Path manual parsing (out-of-tree D:\.claude-rag, không commit project).
Re-bootstrap: 2,421 → 2,628 chunks (+207 user-level memory 23 file).
Cache SHA256 hit perfect — 2nd run 6.5s vs initial 60.9s (10× speedup).

+1 memory user-level NEW feedback_rag_distributed_ownership.md ~200 lines
documenting 2 decisions + setup-once scale-distributed pattern reusable.

RAG indexing + rerank verify S26 content: 5/6 query hit rerank 0.498-0.926.
Best hit "em main project X build infrastructure docs không bootstrap project Y"
→ rerank 0.926 — semantic search Anthropic Contextual Retrieval working PERFECT.

Pending S27+ updated:
- Phase 5 SKIP em (distributed approach chốt)
- Phase 6 Option 4a — 4 PowerShell scripts (start/stop/status/dashboard) + $PROFILE aliases (~30 phút)
- Phase 7 rag-onboarding-guide.md 13 section (11 outline cũ + §12 monitoring + §13 distributed) (~40 phút)
- 4 em main project khác tự setup ~10 phút khi anh mở session
