[CLAUDE] Docs: adopt Harness-9 — L2 archive dark-matter recovery (4 sub) + adap 2-workflow mandate (S70)

3-stage Workflow run-id evidence: investigate wf_be952f3c-97f / implement wf_a58e0d15-beb / audit wf_9520d8cd-4fe.

PART 1 (L2 recovery): 4 over-cap sub (cicd-monitor/investigator-codebase/reviewer/implementer-backend)
curated L1->L2 byte-exact + archive/_INDEX.md (substring sha-keyed pointers, no line-hints)
+ <period>.gist.md (4-field distill, distill-gen:1, verbatim frozen). All 4 MEMORY.md now < 25KB
auto-inject cap (closes P1 curate-debt). ~240KB archive no longer RAG-dark. 0-byte-loss git+sha
verified (Stage C audit + em-main self-gate on 2 reviewer StructuredOutput no-returns). Read-side
gap fixed (MEMORY.md L5 header -> _INDEX). + memory-budget.json (seed-by-measure) +
scripts/measure-agent-memory.ps1 + .ragignore guard.

PART 2/3 (process mandate): every adap = 2 separate workflows (implement + review) + report with
run-id; short-but-needs-confirm still requires review. Codified in .claude/commands/adap-apply.md
+ agents/README.md (Upgrade S70) + session-start.md (§2.1.2 budget-audit, pending-restart).

adap-report + email-back to AI_INFRA (body-hash 7c07b716e775).

 > **Upgrade S66 (2026-06-16 — Harness-8 all-inherit + workflow-fastest adopt):** 🔴 BẮT BUỘC (anh-chốt, mọi sister; chất lượng trên chi phí). **H8.1** — toàn bộ 11 sub-agent có memory → `model: inherit` (ăn top-tier lead), **GỠ cơ chế demote two-tier của Harness-4** (7 sub pin `claude-opus-4-8` đã flip `inherit`: 2 implementer · test-specialist · cicd-monitor · investigator-api · frontend-designer · tooling-auditor; 4 đã-inherit giữ nguyên reviewer·investigator-codebase·database-agent·harvest-curator). SE KHÔNG có helper/gopher rẻ để chừa → cả 11 lên inherit. Escape-hatch per-task `tier:'opus'` (hmw.js) GIỮ cho sweep/cost. **H8.2** — chạy workflow nhanh nhất: **song song tối đa + xuất nhanh + lead auto-HMW** cho task substantive (theo H6) — "nhanh" = parallelism, **KHÔNG phải hạ model**. **Caveat (trung thực):** runtime HIỆN KHÔNG đổi (inherit = Opus 4.8 1M vì Fable suspended H5 — trùng two-tier đã collapse); khác biệt thật khi Fable về (cả đội tự lên Fable 5 không sửa frontmatter) + H5.6 restore gọn hơn (chỉ đổi lead). Frontmatter no hot-reload → **executed-file, VERIFIED-pending-restart**. `[1m]` cấm trong frontmatter `model` (gotcha #37). adap-report `2026-06-16-Governance-harness-8-all-inherit-workflow-fastest.md`.
