Two problems made deep research report "No information could be gathered" even
after it had extracted findings, on slow local models (reporter served a 20B
via LM Studio):
- _synthesize hard-capped its LLM call at timeout=60, while extraction uses the
user's extraction_timeout (300s here) and the final report uses 180s. The slow
model needed >60s to synthesize the round's findings, so synthesis timed out
after 3 attempts. Raised it to 180s to match the final-report call.
- When synthesis produced no report (it returns the unchanged, still-empty
report on failure during round 1), the run hit
`if not report: return "No information could be gathered…"` and discarded the
findings it had already gathered. Now it falls back to a compiled report built
from those findings (_fallback_report) so the user keeps the gathered material.
Tests stub the LLM (no live model/DB), pin the synthesis timeout >= 180, that the
fallback surfaces the findings rather than the give-up message, and that a failed
synthesis preserves the previous report.
