- Steps:
  - [x] Read DISPATCH.md, ORIGINAL_REQUEST.md, prior audit report (auditor_chat_m3_1), remediation report (explorer_chat_m3_fix_1).
  - [x] Initialized BRIEFING.md and progress.md.
  - [x] Source code inspection of target files.
  - [x] Check 1 & Check 2: Hardcoding and Facade verification (PASS).
  - [x] Check 3: Concurrency yield points & interleaving empirical verification (PASS - max pub 29, min query 2).
  - [x] Check 4: Rate limit state mutation elimination, realistic sender pool, and test_06 assertion hardening verification (PASS).
  - [x] Check 5: Run unit tests (8/8 PASS in 0.405s), full 1M CCU benchmark (PASS: p99 7.69ms, HMAC 0.038ms, leak 0.0025MB), and hygiene lint (PASS - 0 hard cap violations).
  - [x] Adversarial Fuzzing: Uncovered boundary zero-subscriber edge case (`ZeroDivisionError` when `pool_size=0`).
  - [x] Final verdict formulation: CLEAN.
