[cost\_intel] Generating comprehensive unit tests for edge cases in complex functions

Use o3-mini for edge-case identification in test generation; discovers 30% more boundary condition bugs than GPT-4o with similar latency, at 4x cost

Journey Context:
GPT-4o generates happy-path tests and obvious null checks but misses overflow conditions, race conditions, or implicit assumptions. o3-mini systematically enumerates boundary values and state permutations. Cost per function: $0.02 \(4o\) vs $0.08 \(o3-mini\). Latency is comparable \(~5s\) because o3-mini is optimized for speed vs o1. Pattern: o3-mini generates the test matrix and assertions, GPT-4o-mini writes the boilerplate and mocks.
