The manually edited openapi.json had field ordering that differed from
what export-api-schema generates. Regenerated using:
  poetry run export-api-schema --output ../frontend/src/app/api/openapi.json
  pnpm prettier --write src/app/api/openapi.json

+"""Pending-message buffer for in-flight copilot turns.
+
+When a user sends a new message while a copilot turn is already executing,
+instead of blocking the frontend (or queueing a brand-new turn after the
+current one finishes), we want the new message to be *injected into the
+running turn* — appended between tool-call rounds so the model sees it
+before its next LLM call.
+
+This module provides the cross-process buffer that makes that possible:
+
+- **Producer** (chat API route): pushes a pending message to Redis and
+  publishes a notification on a pub/sub channel.
+- **Consumer** (executor running the turn): on each tool-call round,
+  drains the buffer and appends the pending messages to the conversation.
+
+The Redis list is the durable store; the pub/sub channel is a fast
+wake-up hint for long-idle consumers (not used by default, but available
+for future blocking-wait semantics).
+
+A hard cap of ``MAX_PENDING_MESSAGES`` per session prevents abuse.  The
+buffer is trimmed to the latest ``MAX_PENDING_MESSAGES`` on every push.

-"""Tests for transcript context coverage when switching between fast and SDK modes.
-
-When a user switches modes mid-session the transcript must bridge the gap so
-neither the baseline nor the SDK service loses context from turns produced by
-the other mode.
-
-Cross-mode transcript flow
-==========================
-
-Both ``baseline/service.py`` (fast mode) and ``sdk/service.py`` (extended_thinking
-mode) read and write the same CLI session store via
-``backend.copilot.transcript.upload_transcript`` /
-``download_transcript``.
-
-Fast → SDK switch
------------------
-On the first SDK turn after N baseline turns:
-  • ``use_resume=False``  — no CLI session exists from baseline mode.
-  • ``transcript_msg_count > 0`` — the baseline transcript is downloaded and
-    validated successfully.
-  • ``_build_query_message`` must inject the FULL prior session (not just a
-    "gap" since the transcript end) because the CLI has zero context without
-    ``--resume``.
-  • After our fix, ``session_id`` IS set, so the CLI writes a session file
-    on this turn → ``--resume`` works on T2+.
-
-SDK → Fast switch
------------------
-On the first baseline turn after N SDK turns:
-  • The baseline service downloads the SDK-written transcript.
-  • ``_load_prior_transcript`` loads and validates it normally — the JSONL
-    format is identical regardless of which mode wrote it.
-  • ``transcript_covers_prefix=True`` → baseline sends ONLY new messages in
-    its LLM payload (no double-counting of SDK history).
-

-"""Tests for the pre-create assistant message logic that prevents
-last_role=tool after client disconnect.
-
-Reproduces the bug where:
-  1. Tool result is saved by intermediate flush → last_role=tool
-  2. SDK generates a text response
-  3. GeneratorExit at StreamStartStep yield (client disconnect)
-  4. _dispatch_response(StreamTextDelta) is never called
-  5. Session saved with last_role=tool instead of last_role=assistant
-
-The fix: before yielding any events, pre-create the assistant message in
-ctx.session.messages when has_tool_results=True and a StreamTextDelta is
-present in adapter_responses.  This test verifies the resulting accumulator
-state allows correct content accumulation by _dispatch_response.

-    This is the shared context primitive used by both the SDK path
-    (``use_resume=False`` → ``<conversation_history>`` injection) and the
-    baseline path (OpenAI messages array).
-
-    How it works:
-
-    - When a transcript exists, ``TranscriptBuilder.load_previous`` preserves
-      ``isCompactSummary=True`` compaction entries, so the returned messages
-      mirror the compacted context the CLI would see via ``--resume``.
-    - The gap (DB messages after the transcript watermark) is always small in
-      normal operation; it only grows during mode switches or when an upload
-      was missed.
-    - Falls back to full DB messages when no transcript exists (first turn,
-      upload failure, or GCS unavailable).
-    - Returns *prior* messages only (excluding the current user turn at
-      ``session_messages[-1]``).  Callers that need the current turn append
-      ``session_messages[-1]`` themselves.
-    - **Tool calls from transcript entries are flattened to text**: assistant
-      messages derived from the JSONL use ``_flatten_assistant_content``, which
-      serialises ``tool_use`` blocks as human-readable text rather than
-      structured ``tool_calls``.  Gap messages (from DB) preserve their
-      original ``tool_calls`` field.  This is the same trade-off as the old
-      ``_compress_session_messages(session.messages)`` approach — no regression.
-
-    Args:
-        download: The ``TranscriptDownload`` from GCS, or ``None`` when no
-            transcript is available.  ``content`` may be either ``bytes`` or
-            ``str`` (the baseline path decodes + strips before returning).
-        session_messages: All messages in the session, with the current user
-            turn as the last element.
-
-    Returns:
-        A list of ``ChatMessage`` objects covering the prior conversation
-        context, suitable for injection as conversation history.

-#
-# Motivation: `backend.util.cache.cached` stores its result in a process-wide
-# dict for ttl_seconds. Async clients (AsyncOpenAI, httpx.AsyncClient,
-# AsyncRabbitMQ, supabase AClient, ...) wrap connection pools whose internal
-# asyncio primitives lazily bind to the first event loop that uses them. The
-# executor runs two long-lived loops on separate threads; once the cache is
-# populated from loop A, any subsequent call from loop B raises
-# `RuntimeError: ... bound to a different event loop`, surfaced as an opaque
-# `APIConnectionError: Connection error.` and poisons the cache for a full
-# TTL window.
-#
-# Use `per_loop_cached` (keyed on id(running loop)) or construct per-call.

-"""Unit tests for the transcript watermark (message_count) fix.
-
-The bug: upload used message_count=len(session.messages) (DB count).  When a
-prior turn's GCS upload failed silently, the JSONL on GCS was stale (e.g.
-covered only T1-T12) but the meta.json watermark matched the full DB count
-(e.g. 46).  The next turn's gap-fill check (transcript_msg_count < msg_count-1)
-never triggered, so the model silently lost context for the skipped turns.
-
-The fix: watermark = previous_coverage + 2 (current user+asst pair) when
-use_resume=True and transcript_msg_count > 0.  This ensures the watermark
-reflects the JSONL content, not the DB count.
-
-These tests exercise _build_query_message directly to verify that gap-fill
-triggers with the corrected watermark but NOT with the inflated (buggy) one.
