prax log watchdog covers branch logs/ dirs — .jsonl runaway growth caught (built by @prax). Root cause: rotation was .log-hardcoded and .jsonl writers are raw open('a') appenders bypassing prax; the watchdog safety net only scanned system_logs. Now scans all src/aipass/*/logs/ for .log+.jsonl (WARN 1MB / CRITICAL 10MB unrotated), enforce truncates to last 5000 lines, log-audit shows system + branch scopes. 11 new tests, 947 suite green. Offender writers (hooks 63MB engine.jsonl, backup 31MB operations.jsonl, trigger 7MB medic log) routed to owners separately.#659
