+The chatgpt.com/backend-api/codex endpoint has an intermittent failure mode

+cutoff (instead of waiting out the much longer wall-clock stale timeout) so the

+considered healthy and only the wall-clock stale timeout applies — long
+generations must never be interrupted by the TTFB cutoff.
+
+The "bytes flowing" signal is ``agent._codex_stream_last_event_ts``, set on
+*any* event by ``codex_runtime.run_codex_stream`` — so reasoning-only or

+"""Tests for HERMES_HOME credential-file read blocking in file_safety.
+
+Regression for https://github.com/NousResearch/hermes-agent/issues/17656 —
+``read_file`` was previously only sandboxed against ``HERMES_HOME`` itself,
+which left ``auth.json`` and ``.anthropic_oauth.json`` (plaintext provider
+keys + OAuth tokens) readable by the agent. A prompt-injection reaching
+``read_file`` could exfiltrate active credentials.
+
+These tests verify that ``get_read_block_error`` returns a denial message
+for the credential stores while leaving arbitrary ``HERMES_HOME`` files
+readable, and that the existing ``skills/.hub`` deny still applies.

+"""Regression tests for issue #31179.
+
+Before the fix:
+  - ``auxiliary.vision.provider: openai`` silently failed to resolve because
+    ``openai`` is not a first-class provider in PROVIDER_REGISTRY (only
+    ``openai-codex`` for OAuth and ``custom`` for OPENAI_BASE_URL).
+  - The vision branch of ``call_llm`` then silently fell back to ``auto``
+    which happily picked the user's main provider (e.g. DeepSeek), sending
+    image content to a text-only endpoint and producing cryptic
+    ``unknown variant 'image_url', expected 'text'`` errors.
+  - ``check_vision_requirements`` used the explicit-only path, so
+    ``vision_analyze`` disappeared from the tool list while ``browser_vision``
+    stayed (its check_fn only validated the browser).
+
+The three fixes covered here:
+  1. ``provider: openai`` in auxiliary task config resolves to
+     ``custom`` + ``https://api.openai.com/v1``.
+  2. The vision auto-detect chain skips the user's main provider when it
+     reports ``supports_vision=False`` instead of routing image content to
+     a text-only endpoint.
+  3. ``check_vision_requirements`` mirrors the runtime fallback chain so
+     ``vision_analyze`` shows up whenever the auto chain can serve vision,
+     and ``browser_vision`` gates on vision availability as well.

-"""Regression test for #4469.
+"""Regression tests for active-session TEXT follow-up queueing.
 
-When the agent is actively running (session present in
-``adapter._active_sessions``) and the user fires off multiple TEXT
-follow-ups in rapid succession, the previous behaviour was a single-slot
-replacement at ``gateway/platforms/base.py``:
-
-    self._pending_messages[session_key] = event
-
-So three rapid messages ``A``, ``B``, ``C`` arriving while the agent was
-still working on the initial turn produced a pending slot containing only
-``C``; ``A`` and ``B`` were silently dropped.
-
-The fix routes the follow-up through ``merge_pending_message_event(...,
-merge_text=True)`` so TEXT events accumulate into the existing pending
-event's text instead of clobbering it.  Photo / media bursts continue to
-merge through the same helper (they always did).
+When the agent is actively running, rapid text follow-ups should survive as
+one next-turn pending message instead of clobbering each other. In
+``busy_text_mode=queue`` those active follow-ups first pass through a short
+debounce so bursty multi-message thoughts are merged before the active drain
+hands off the next turn.
