"Claude 3, Qwen 6: why we set a different fix_verify retry cap per model"

Claude gets 3 retries. Qwen gets 6. Everything else gets 5. That is the default fix_verify_retry_cap in Codens Purple right now, after a few weeks of staring at fix-rate curves per model. It started as one global cap, the same number for every model the workflow could route to. We changed it once we had enough production data to see that the same number was both too high for one model and too low for another at the same time. This is the story of the split, what the loop actually does, and the few lines of code that put the policy in.
