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.
Salvaged from PR #35130 (the safe subset of jnibarger01's security pass):
- threat_patterns.py: replace unbounded (?:\w+\s+)* filler with bounded
{0,8} + cap scan input at MAX_SCAN_CHARS (64KiB), and bound the .*
runs in the exfil/config-mod patterns. Kills catastrophic backtracking
on adversarial near-misses.
- hermes_state.py: cap FTS5 query length (MAX_FTS5_QUERY_CHARS) and
extract quoted phrases with a linear scan instead of a regex so
pathological quote runs can't induce backtracking.
- acp_adapter/edit_approval.py + agent/tool_dispatch_helpers.py: recognize
'*** Move File: src -> dst' V4A headers so patch-mode edits are
permissioned/traversal-checked (previously only Update/Add/Delete), and
surface a proposal for mode=patch V4A calls (previously replace-only).
Tests: +ReDoS-bound + FTS5-cap + Move-File-target + V4A-approval cases.
#28063 fixed the macOS `/tmp`→`/private/tmp` symlink issue by checking
the RAW path (pre-resolve) against startswith('/tmp/'). That works on
Linux + macOS but not on Windows — Path('/tmp/foo').resolve() returns
C:\\tmp\\foo and isn't the real Windows temp anyway.
Replace the hardcoded '/tmp/' prefix with Path(tempfile.gettempdir()).
resolve() + Path.relative_to() — same idiom as the cwd branch just
below. Works correctly on Linux (/tmp), macOS (/private/var/folders/...),
and Windows (%LOCALAPPDATA%\\Temp).
Test rewritten to use tempfile.gettempdir() so the assertion exercises
the same code path on every platform.
Conflict against the just-merged #28063 (raw_path approach) resolved
by replacing the whole raw_path block — tempfile.gettempdir() is
strictly better than that intermediate fix.
Salvage of #28262 by @Zyrixtrex.
