the session title thread and the conversation thread, which always occurs on the

Uses WeakValueDictionary for automatic cleanup: locks are garbage collected
when no coroutine holds a reference to them, preventing memory leaks from
unbounded growth of session locks. Explicit cleanup also occurs
in `delete_chat_session()`.
Uses redis-py's built-in Lock (Lua-script acquire/release) so lock acquisition

"""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).
Scenario table (SDK _build_query_message)
==========================================
| # | Scenario | use_resume | tmc | Expected query message |
|---|--------------------------------|------------|-----|---------------------------------|
| P | Fast→SDK T1 | False | 4 | full session injected |
| Q | Fast→SDK T2+ (after fix) | True | 6 | bare message only (--resume ok) |
| R | Fast→SDK T1, single baseline | False | 2 | full session injected |
| S | SDK→Fast (baseline loads ok) | N/A | N/A | transcript covers prefix=True |

"""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.

"""Return context messages for the current turn: transcript content + gap.
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.

# 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.

"""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.
