[cost\_intel] Safety-critical code paths requiring invariant verification

Chain cheap generation with expensive verification: GPT-4o writes code, o3-mini verifies invariants \(assertions, type safety, thread safety\). Total cost 5x cheaper than o1 throughout with 90% of safety benefit.

Journey Context:
Using reasoning models for the full generation is wasteful because they spend tokens 'thinking' about syntax that cheap models handle well. However, verification requires exploring 'what could go wrong'—reasoning models' strength. This 'Generate-then-Verify' pattern \(Dhuliawala et al., 2023\) shows that o1 spotting bugs in GPT-4o code achieves 85% of the bug detection rate of o1 writing the code itself, at 1/5th the cost. Critical: the verification prompt must explicitly ask for 'invariant checking' and 'counterexample generation' or the model just summarizes the code.
