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.
Remove unused imports (F401) and duplicate/shadowed import
redefinitions (F811) across the codebase using ruff's safe
autofixes. No behavioral changes -- imports only.
- ~1400 safe autofixes applied across 644 files (net -1072 lines)
- __init__.py re-exports preserved (excluded from F401 removal so
public re-export surfaces stay intact)
- Re-exports that are imported or monkeypatched by tests but look
unused in their defining module are kept with explicit # noqa:
F401 (gateway/run.py load_dotenv; run_agent re-exports from
agent.message_sanitization, agent.context_compressor,
agent.retry_utils, agent.prompt_builder, agent.process_bootstrap,
agent.codex_responses_adapter)
- Unsafe F841 (unused-variable) fixes deliberately skipped -- those
can change behavior when the RHS has side effects
- ruff lints remain disabled in pyproject.toml (only PLW1514 is
selected); this is a one-time cleanup, not a config change
Verification:
- python -m compileall: clean
- pytest --collect-only: all 27161 tests collect (zero import errors)
- core entry points import clean (run_agent, model_tools, cli,
toolsets, hermes_state, batch_runner, gateway)
- static scan: every name any test imports directly from an edited
module still resolves
Adds first-class `client_cert` / `client_key` config keys so MCP servers
behind mTLS work without an external TLS-terminating proxy. Resolves
inbound community question (Jeremy W.).
Schema (per `mcp_servers.<name>`, HTTP/SSE only):
- `client_cert: "/path/to/combined.pem"` — single PEM with cert + key
- `client_cert: "/path/to/cert"` + `client_key: "/path/to/key"` — separate
- `client_cert: [cert, key]` or `[cert, key, password]` — list form,
with optional passphrase for encrypted keys
Paths support `~` expansion. Missing files raise a server-scoped
`FileNotFoundError` at connect time rather than failing later with an
opaque TLS handshake error.
Wiring:
- New SDK HTTP path (mcp >= 1.24): `cert=` on the user-owned
`httpx.AsyncClient` alongside the existing `verify=` handling.
- SSE path: routed through an `httpx_client_factory` that wraps the
SDK's defaults (follow_redirects=True) and layers `verify` + `cert`
on top. The factory is only injected when needed, so the SDK's
built-in `create_mcp_http_client` keeps being used in the default
case.
- Deprecated mcp<1.24 path left untouched — that SDK's
`streamablehttp_client` signature doesn't expose `cert`, and adding
it would be dead code.
Also documents the previously-undocumented `ssl_verify` key (bool or
CA bundle path) in the MCP config reference.
Tests:
- `tests/tools/test_mcp_client_cert.py` (new, 19 tests):
- `_resolve_client_cert` helper: all three input forms, `~` expansion,
missing-file and validation errors.
- HTTP transport: `cert=` forwarded into `httpx.AsyncClient` for
string and tuple forms; absent when unset; missing-file error
propagates.
- SSE transport: factory only injected when cert or non-default
verify is set; factory applies cert, custom CA bundle, and
preserves `follow_redirects=True` + forwarded headers/auth.
- Existing tests: 200/200 in `test_mcp_tool.py` + `test_mcp_sse_transport.py`
still pass.
