Eight adapters (discord, telegram, wecom, matrix, whatsapp, simplex, feishu, weixin) each kept a
copy of the delayed text-batch flush that base._enqueue_text_event schedules. Two correctness
fixes had landed in single copies only: Discord's asyncio.shield around the dispatch (#12444 —
a late chunk cancelling the flush task aborted the in-flight agent turn) and WeCom/Weixin's
synchronous task-identity check before the pop (a superseded task waking late popped the event
and the successor found nothing). The other adapters carried both bugs latent.
The base now owns `_flush_text_batch` with both fixes, plus the `_pending_text_batches` /
`_pending_text_batch_tasks` dicts and `_SPLIT_THRESHOLD` / delay attrs (defaults; adapters set
their own). Platform policy goes through three small hooks instead of a copied body:
`_text_batch_delay_for(pending)` (Telegram's fast/short tiers, WeCom's attachment-only wait),
`_pop_text_batch(key)` (Feishu's side count table) and `_dispatch_text_batch(event)` (Feishu's
per-chat lock). Telegram keeps its `_flush_buffered` body because its contract differs on
purpose — a cancel after the pop must hold-and-re-raise so teardown can stop a flush — and gains
the identity check there. Matrix's `_split_threshold` is renamed to the shared `_SPLIT_THRESHOLD`;
SimpleX exposes its single delay through the shared attr names.
`helpers.TextBatchAggregator` (zero users) sits inside the revert-scheduled PLUGIN-COMPAT block
and is left for that revert.
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.
Raise the Matrix adapter default chunk size from 4,000 to 16,000
characters and allow overrides via config.yaml or MATRIX_MAX_MESSAGE_LENGTH.
