Report #83743

[synthesis] Agent launches 3 parallel searches, 2 return errors/timeout, 1 returns partial match; agent terminates with 'found answer' using only the partial match, ignoring the failed queries that might have held better data

Implement quorum logic for parallel tool calls - require either \(a\) successful completion of majority of parallel attempts, or \(b\) explicit acknowledgment of failed attempts and justification for proceeding with partial data; never silently ignore failed parallel branches

Journey Context:
Parallel tool calls improve latency but create race conditions in agent reasoning. When 2/3 sources fail, the agent doesn't recognize it has incomplete information - it treats the single success as 'the answer.' This is especially dangerous in RAG where one retriever fails silently \(network timeout\) and the other returns irrelevant chunks that happen to match keywords. Quorum logic forces explicit handling of partial failure states rather than silent degradation.
