[CLAUDE] Docs: adopt Harness-17 memory self-improvement loop (Đo→Tinh-chỉnh→Kiểm) — 2-workflow, 0 prod code

- engine §I codify 10 red-floor: A1 HCV/A2 load-fid/B1 signal→action/B2 CG-1 termination/B3 build-gap-vs-floor-rot/C1 spec-audit/C2 spot-check/C3 single-writer/C4 provenance/CG-2 age-exempt
- REUSE-cite (no rebuild): A2=§H MFE · C3=D9 · CG-2=§G.2b value_protect · archive=§A
- new mechanized: scripts/memory-selfimprove-audit.ps1 (C1 spec-audit NO-API exit-0, runtime-verified — bắt frontend-designer over-cap GAP thật)
- new: .claude/governance/reinject-ledger.md (B2 CG-1 git-tracked append-only N=3, tách khỏi budget.json)
- wire session-start §2.1.7 (loop-DÒ) + session-end §L.b(c) (loop-REFINE)
- vocab: HCV alias no-seed (coverage 3-way) + governance-detectors C3-comment; cap-fix 220K→380K-pointer
- 2-workflow (Harness-9): WF1 wf_f085d7c4-d78 (ground-truth) + WF2 wf_8e73c1d6-ee6 (3-lane PASS 0-blocking)
- adap-report + checklist-pointer + email AI_INFRA (hash 54789e19, hash-verified self-consistent)
- dogfood: WF1 agent self-write MEMORY.md reverted (D9/AS-10 containment; archive missing → saved 8.5KB)
