[CLAUDE] Docs: adopt Harness-16 MFE (memory-fidelity-EVAL) — 2-workflow + email AI_INFRA

Adopt AI_INFRA Harness-16 (3 broadcast 2026-06-29) qua 2-workflow mandate:
WF1 implement wf_4c63e1bd-99e + WF2 review wf_13e3d35a-023 (PASS 0-blocking).

MFE = coverage/retention eval (do nap-vs-nho-vs-dung bang SO DO). DISTINCT
voi H6.7 memoryDelta-routing-fidelity (vocab-fork WF1 reviewer bat duoc).

Built (em-main single-writer, 0 production code):
- scripts/mfe-eval.ps1 deterministic NO-API (ASCII #30, exit 0): LEAD coverage-FIT
  (token-RANGE, cap live-read) + age-band flag-not-cut + Goodhart-anchor strikes/RCA;
  SUB per-role coverage do-that (prose->N/A khong 0%); sub-workflow N/A. Smoke 3-tier PASS.
- memory-budget.json :mfe config + eval/mfe/ (seed sample-questions stable-id + README)
  + engine §H + artifact-row + C3-comment + wire session-start §2.1.6 / session-end §L.b(c)
  opt-in + agents/README S93. Judge layer = SCAFFOLD-only (honest nac).

adap-report harness-16-mfe + harness-15-v3 (covered/folded) + email outbox/ai_infra.
