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.
When the #54878 self-healing path drops a stale sessions.json entry, the
fix at gateway/session.py:1765 now checks _should_reset() before falling
through to DB recovery. This test covers the case where the stale entry's
session is overdue under an idle/daily reset policy — it must create a
fresh session, set auto-reset metadata, and NOT call reopen_session().
Regression tests for find_latest_gateway_session_for_peer and
SessionStore stale-routing self-heal when end_reason is ws_orphan_reap.
Pin manual approval mode in blocking E2E tests so smart aux-LLM
resolution does not flake CI.
The routing-heal added to get_or_create_session calls
SessionDB.get_compression_tip; the stale-guard suite's bare MagicMock db
returned a Mock the heal then assigned as session_id, failing JSON
serialization. Model the real contract (a non-compressed session's tip is
itself) so the heal is a correct no-op.
Detect a routing key whose session is already ended in state.db
(end_reason set) inside get_or_create_session and drop the stale entry
instead of silently routing the message into a closed session.
Previously the only runtime cleanup of sessions.json was the startup
_prune_stale_sessions_locked (#52808/#54138), which requires a restart.
A session ended while the gateway stays alive — any path that finalizes
the DB row without clearing sessions.json — left a live routing key
pointing at a closed session. get_or_create_session never consulted
end_reason, so it returned that stale entry and every subsequent message
was silently dropped (no log, no error, no response) until the next
restart. This is the live-gateway variant of #52804/FM9, which needed an
actual gateway crash.
The guard drops the stale entry and falls through to
_recover_session_from_db, which reopens agent_close-ended rows and
resumes the SAME session_id (transcript preserved); if the row ended for
a non-recoverable reason (e.g. /new) it correctly starts a fresh
session. A warning is logged so the event is visible (the field
incident reported zero log output).
Adds tests/gateway/test_session_store_runtime_stale_guard.py covering
the _is_session_ended_in_db helper and the end-to-end routing self-heal
(recover-vs-fresh, live-entry untouched, stale-wins-over-suspended,
force_new short-circuit).
Closes#54878.
