Second, deeper pass over tools/gateway/hermes_cli plus first pass over
the trees wave 1 missed (acp, acp_adapter, skills, computer_use, docker,
dashboard, conformance, monitoring, secret_sources, hermes_state,
providers). Same rubric as wave 1 (AGENTS.md test policy); security,
alternation/caching invariants, issue-number regressions, and E2E kept.
Real test-quality fixes found and rooted out along the way:
- tests/tools/test_command_guards.py made real auxiliary-LLM HTTPS calls
(DEFAULT_CONFIG smart-approval leaked in) — pinned approval
mode=manual via autouse fixture: 17.4s → 0.4s.
- test_model_switch_custom_providers.py / test_user_providers_model_switch.py
silently probed live provider catalogs (~2s/test) — stubbed
cached_provider_model_ids/provider_model_ids/fetch_api_models.
- test_telegram_noise_filter.py: 15-platform copy-paste matrix over
shared gateway.run logic → 3 representative platforms (55s → 3.9s).
- test_gateway_shutdown.py: stop()'s 5s interrupt-deadline loop spun on
MagicMock agents — interrupt.side_effect now clears _running_agents
(22s → 1.0s).
- test_gateway_inactivity_timeout.py poll-harness timings shrunk 3-5x
(24s → 1.1s); test_mcp_stability.py backoff/SIGTERM-grace sleeps
patched (15.4s → 2.5s); test_async_delegation.py negative-drain wait
5s → 0.5s.
- test_telegram_init_deadline.py: loop-block margin restored to 1.0s
with rationale comment — the watchdog-dump assertion needs the loop
blocked well past deadline+grace under parallel load (flaked once in
the 40-worker verification run at a 0.2s margin).
Verification: full hermetic suite via scripts/run_tests.sh —
2,438 files, 21,718 tests passed, 0 failed, 293.9s wall.
Suite totals vs original baseline: 46,820 → 19,757 test functions
(−57.8%), wall 583.5s → 293.9s (−50%), subprocess CPU 13,564s → 11,623s.
On hosts where the cgroup v2 cpu/memory/pids controllers are not delegated
to the docker/podman process (unprivileged Proxmox LXCs, some rootless and
nested setups), --pids-limit/--cpus/--memory cause every container start to
fail with OCI runtime error / exit 126, breaking terminal + execute_code.
- Add _cgroup_limits_available(image): one-shot, host-wide cached probe that
spawns a throwaway container from the sandbox image itself (sleep 0) with
all three flags together, mirroring the existing _storage_opt_supported
probe-and-degrade pattern.
- Remove --pids-limit from static _BASE_SECURITY_ARGS; apply it (default 256
via _DEFAULT_PIDS_LIMIT) in resource_args gated on the probe.
- Gate --cpus and --memory on the same probe.
Behavior unchanged on cgroup-capable hosts; graceful degradation with a
one-time warning where controllers aren't delegated.
Fixes#6568.
