[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).
