Report #101269

[synthesis] Claude adds uncertainty caveats while GPT-4o sounds confident, so the same downstream parser behaves differently

For Claude, expect and optionally strip caveat prefixes, or prompt it to commit to a concise answer; for GPT-4o, add an explicit confidence-score field because it is less likely to self-flag uncertainty.

Journey Context:
Claude is trained to flag uncertainty and refuse or qualify on knowledge-boundary tasks, while GPT-4o tends toward definitive-sounding answers that may be wrong. This makes Claude safer for human review but harder for automated extraction, while GPT-4o looks structured but can smuggle hallucinations.
