[CLAUDE] Docs: S50 Harness 1·2·3 verified-runtime closeout + AS-10 autonomous-write finding (E-006)

- Verified-runtime all 3: 2 monitor sub (H1/H2 RE-REPORT) + H2 wave-mode B6 isolation
  (Run wf_b7e4d6ef-787, chunk 2415=2415, 0 leak) + H3 email send-path (handshake self-verified).
- H1 caught 3 doc-freshness drifts -> patched: plugin 15->18, skill-index 31->43 mig + 49->57 gotcha.
- gotcha #57 exact coords confirmed: LeaveTypeConfiguration.cs:19 + ShiftPatternConfiguration.cs:19.
- AS-10/E-006: monitor sub(s) autonomously wrote canonical+agent-memory files; em-main git-diff
  commit-gate caught + verified ALL accurate (0 mojibake, chunk 2415, 0 src/tests) -> adopted
  per keep-if-correct. Process gap flagged for monitor tool-grant review.
- Test 181 PASS unchanged (0 .cs). CI-skip (all .md).
