- AgentRunner.run: offload to a worker-thread event loop when called
from inside a running loop (Jupyter, FastAPI handlers) — mirrors
pipeline._run_async; Runner.run_sync raised RuntimeError there.
- SQLiteStorage: create connections with check_same_thread=False so
close() can actually close connections created by worker threads.
Each thread still gets its own connection via threading.local; with
the default True those closes raised ProgrammingError (silently
swallowed) and leaked every worker connection.
- CloudBackend.query: non-streaming chat completions now use a 300s
timeout and a single attempt. The default 30s ReadTimeout fired
before generation finished and the retry loop re-billed the full
server-side retrieval + generation up to three times. _request gains
retries/timeout overrides; the exhausted-retry path also no longer
sleeps before raising.
- MarkdownParser: content before the first heading (abstract/preamble)
becomes a node instead of being silently dropped and unretrievable;
a file with no headings at all yields a single document node instead
of zero nodes (which pushed an empty page list into the pipeline).
- LegacyCloudAPI.is_retrieval_ready: API failures (revoked key, network
down) now propagate as PageIndexAPIError instead of reading as
"not ready", which turned polling loops into infinite loops.
Adds regression tests for each fix.
