Each item has a falsifying test in adapters/_common/tests/test_edge_cases.py (17 tests total). Items not requiring code changes still have tests that codify the safe behavior so a future regression would be caught. ## Items 1-12 Agent-Control-Standard#1 rfc8785 JCS consistency — test confirms fallback matches the rfc8785 package byte-for-byte on every ACS envelope shape we ship. No code change needed; a mixed-install signature mismatch would surface as test failure. Agent-Control-Standard#2 Guardian regex DoS, server-side: _matches_destructive_bash now returns "too_large" for inputs > DESTRUCTIVE_SCAN_MAX_LEN (8 KiB). The Guardian denies with reason_codes=["input_too_large"] — fail-safe direction. Previously, _common had the cap but the Guardian iterated patterns directly, leaving the server unprotected. Agent-Control-Standard#3 HA Guardian replay window: persist() now takes an exclusive flock on a .lock sidecar, re-reads on-disk state, merges (union of seen_request_ids / seen_nonces with earliest-timestamp wins), and atomically writes. check_replay re-reads the state on every call so Guardian A's writes are visible to Guardian B within one request. Cross-instance replay window closed under shared ACS_GUARDIAN_STATE_DIR. Agent-Control-Standard#4 Unbounded seen_request_ids: switched to dict {rid: timestamp}. New evict_old_request_ids() drops entries older than 2 × skew window (replay impossible past skew anyway). check_replay calls eviction opportunistically every 100 inserts. Memory bound is now O(skew_window / inter-request-time), not unbounded. Backwards- compat for list-format state files preserved. Agent-Control-Standard#5 Handshake cache TTL: do_handshake skips cache files older than ACS_HANDSHAKE_CACHE_TTL_SECONDS (default 3600s). Operator config changes propagate within the TTL. Agent-Control-Standard#6 NAT id(context) collision: WeakKeyDictionary fallback for contexts that reject attribute assignment. Last-resort path (object isn't weak-referenceable either) returns a fresh uuid4 per call and emits an audit event — pre→post correlation is lost in that path, but no silent collision. Agent-Control-Standard#7 Unicode / NULL / surrogate round-trip: emoji, NULL bytes, multi- plane unicode all sign+verify cleanly. JCS handles them via UTF-8 encoding; no code change needed. Agent-Control-Standard#8 ISO 8601 parse resilience: parse_iso8601 already accepts Z suffix, timezone offsets, millisecond + microsecond precision. Test codifies the accepted shapes + asserts garbage is rejected. Agent-Control-Standard#9 ACS_GUARDIAN_HOST_ALLOWLIST: optional env-var allowlist that restricts validate_guardian_url to specific hostnames in addition to the http/https scheme check. Defense in depth against env-var attacks that smuggle a valid http:// URL to internal services. Agent-Control-Standard#10 Cursor session-state file collision: _session_state_path now accepts an optional workspace parameter folded into the hash key. Cursor adapter passes the workspace_path / cwd so two Cursor windows with the same non-UUID conversation_id can't share state. Agent-Control-Standard#11 Guardian envelope schema validation: if jsonschema + ACS_SPEC_DIR are available, every incoming envelope is validated against request-envelope.json before policy evaluation. Malformed envelopes rejected with -32600 Invalid Request. system/ping and handshake/hello exempt because their payload shapes differ. Agent-Control-Standard#12 State-file hash length: bumped _session_state_path and _handshake_cache_path hashes from sha256[:16] (64-bit) to full sha256 (256-bit). Eliminates birthday collisions over deployment lifetime. ## Test counts after this commit (all green, 1 intentional manual skip) _common: 33 (16 security + 17 edge-cases) claude-code: 32 cursor: 50 example-guardian: 20 nat: 24 Total: 159 tests. ## Side-effects of the fixes - Round-trip test fixtures updated to use real UUID session_ids (claude-code/test_adapter.py). Old "test-cc-session" fails the new Guardian-side envelope-schema check, which is correct — non-UUID session_ids never reached the Guardian from real Claude Code. - Cursor adapter wires workspace through to load/save/record session state for Agent-Control-Standard#10 (new _workspace helper). - example_guardian.py imports DESTRUCTIVE_SCAN_MAX_LEN from acs_common to keep the cap in one place.
