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.
`serve` (added in #54568) reused cmd_dashboard wholesale, so it still
behaved like a dashboard: it ran a full vite build every launch, mounted
and served the SPA whenever a stray web_dist/ existed, printed
"Hermes Web UI →", and announced HERMES_DASHBOARD_READY. It's the headless
JSON-RPC/WS backend the desktop app and remote clients run — pure socket
clients that never load the browser SPA.
Mark serve with headless_backend=True (resolved once in cmd_dashboard) and:
- skip _build_web_ui entirely on the serve path
- export HERMES_SERVE_HEADLESS=1 so mount_spa() disables the SPA even when a
dist is present — only the JSON-RPC/WS/API surface is reachable
- announce the bind ("Hermes backend listening on host:port") instead of a
browser/auth-gated URL
- print a neutral HERMES_BACKEND_READY sentinel; dashboard keeps the legacy
one and the desktop port-discovery regex matches either
- preserve serve across the named-profile re-exec so it can't rebuild as
dashboard
`hermes dashboard` is unchanged (builds + serves the browser UI). Backward
compatible: old apps only ever spawn dashboard (legacy token + UI intact)
and never invoke serve; the ready-file side channel is name-agnostic. The
one behavior change is that a remote `hermes serve` no longer serves the
browser dashboard as a side effect — that's `hermes dashboard`'s job.
Tests: serve headless_backend contract, SPA-disabled-with-dist, the
HERMES_BACKEND_READY desktop parse (17/17 node), and the existing
serve/dashboard/web_server suites. AGENTS.md documents the behavior.
Clears the ty diff bot's warnings on the new test: pass real callables to
build_dashboard_parser (not object()) and replace the pytest.mark.parametrize
with a plain loop so the file is stdlib-only.
Add a focused contract test for the headless `serve` command (routes to the
shared dashboard handler, headless by default while `dashboard` is not, accepts
the legacy --no-open, shares the same runtime/lifecycle flag surface). Also
refresh the dashboard.py module docstring to cover both commands.
