[cost\_intel] Trusting o1's visible chain-of-thought as verbatim audit trail for compliance

Treat o1's reasoning tokens as post-hoc summaries, not legal audit trails; implement independent verification layers for regulated decisions \(finance, healthcare\)

Journey Context:
o1/o3's 'thinking tokens' are abridged, human-readable summaries of the internal reasoning process, not verbatim logs. They can contain 'confabulated' steps—plausible-sounding justifications generated after the decision is made. In finance \(loan approval\) or healthcare \(diagnosis support\), relying on this 'show your work' feature creates liability gaps. The model generates rationalizations, not necessarily the actual path taken. Compliance requires deterministic, verifiable logic \(symbolic AI or rule engines\) for the audit trail, with LLM reasoning as input-only, not evidence.
