+"""Tests for #42039 — user messages stored twice in state.db.
+
+When the agent has its own SessionDB reference (``_session_db is not None``),
+``_flush_messages_to_session_db()`` persists messages to SQLite during the
+agent run.  The gateway's ``append_to_transcript()`` must then use
+``skip_db=True`` on all fallback paths to prevent writing a second copy
+to the same SQLite file.
+
+This test covers the two fallback paths that previously lacked
+``skip_db=agent_persisted``:
+
+1. ``agent_failed_early`` path — transient 429/timeout failures
+2. ``not new_messages`` path — edge case where ``history_offset`` exceeds
+   the actual message count

-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.

+"""Tests for config-driven platform access policies at the gateway layer.
+
+Background (#34515): WeCom, Weixin, Yuanbao, QQBot, and WhatsApp expose a
+documented config-driven access surface (``dm_policy`` / ``group_policy`` /
+``allow_from`` / ``group_allow_from`` in ``PlatformConfig.extra``) and enforce
+it at intake —
+a message is dropped inside the adapter and never reaches the gateway unless it
+already passed that policy.
+
+The gateway's env-based allowlist check (``_is_user_authorized``) runs *after*
+the adapter. Before the fix it fell through to an env-only default-deny when no
+``PLATFORM_ALLOWED_USERS`` env var was set, silently rejecting ``dm_policy:
+open`` and config-only allowlists even though the adapter had already
+authorized the sender.
+
+The fix is a single drift-proof contract: adapters that own their access policy
+declare ``enforces_own_access_policy`` (a ``BasePlatformAdapter`` property,
+default ``False``). The gateway trusts that flag and skips the env-only
+default-deny for those platforms, rather than re-implementing each adapter's
+policy logic a second time.

+"""Regression tests for #35314 — empty model on the post-interrupt recovery turn.
+
+After a ``stream_interrupt_abort`` during an active gateway session, the recovery
+turn was sometimes built with ``model=""`` (a transient config-cache miss returned
+an empty ``user_config``). Every API call then failed HTTP 400 "No models
+provided", "trying fallback..." was logged but never executed (the user had no
+fallback configured), and the session went silent until the user re-sent.
+
+These tests pin two fixes:
+  1. ``_resolve_session_agent_runtime`` caches the last successfully-resolved
+     model per session and recovers it when a fresh resolution comes back empty.
+  2. ``_has_pending_fallback`` gates the "trying fallback..." status so it is only
