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.
The Discord/Telegram /model slash command listed providers synchronously
on the gateway's async event loop. list_picker_providers /
list_authenticated_providers are blocking and can fall through to a
synchronous urllib HTTP fetch when the on-disk provider cache is stale,
freezing the loop for 120-150s -> "application did not respond" and
delayed agent starts.
Port #41304's asyncio.to_thread offload to the current handler location.
The handler moved from gateway/run.py to gateway/slash_commands.py
(_handle_model_command); wrap BOTH blocking call sites so the whole bug
class is covered:
- picker path -> list_picker_providers
- text-fallback path -> list_authenticated_providers
asyncio.to_thread is already idiomatic in this module (and asyncio is
imported), so the loop now stays responsive while the (possibly
network-bound) listing runs on a worker thread.
Adds tests/gateway/test_model_command_async_offload.py asserting the
offload contract at the real handler seam for both paths (mutation-
survivable: reverting either to_thread wrap fails the matching test).
