Critical bug fixes from PR review agents: - client.py: eager asyncio.Lock init, Final[frozenset] for _SENSITIVE_KEYS, explicit 429 ToolError after retries exhausted, removed lazy _get_client_lock() and _RateLimiter._get_lock() patterns - exceptions.py: use builtin TimeoutError (UP041), explicit handler before broad except so asyncio timeouts get descriptive messages - docker.py: add update_all to DESTRUCTIVE_ACTIONS (was missing), remove dead _MUTATION_ACTIONS constant - manager.py: _cap_log_content returns new dict (immutable), lock write to resource_data, clean dead task from active_subscriptions after loop exits - diagnostics.py: fix inaccurate comment about semicolon injection guard - health.py: narrow except ValueError in _safe_display_url, fix TODO comment New test coverage (98 tests added, 529 → 598 passing): - test_subscription_validation.py: 27 tests for _validate_subscription_query (security-critical allow-list, forbidden keyword guards, word-boundary test) - test_subscription_manager.py: 12 tests for _cap_log_content (immutability, truncation, nesting, passthrough) - test_client.py: +57 tests — _RateLimiter (token math, refill, sleep-on-empty), _QueryCache (TTL, invalidation, is_cacheable), 429 retry loop (1/2/3 failures) - test_health.py: +10 tests for _safe_display_url (credential strip, port, path/query removal, malformed IPv6 → <unparseable>) - test_notifications.py: +7 importance enum and field length validation tests - test_rclone.py: +7 _validate_config_data security guard tests - test_storage.py: +15 (tail_lines bounds, format_kb, safe_get) - test_docker.py: update_all now requires confirm=True + new guard test - test_destructive_guards.py: update audit to include update_all Co-authored-by: Claude <noreply@anthropic.com>
