Checking a Cost Model Against a Stranger's Config File
Community description: I bounded an ambiguity in a config file at 2.4% and called it immaterial. The model's own header settled it months later, and correcting the assumption pushed a gate from 1.1% off to 3.4% off, outside the tolerance it had been passing.

Automated excerpt
Gate 1 reproduced a third-party runtime's on-disk container byte-for-byte. Gate 2 predicted the size of a model conversion published by different people using a different tool, and came within 1. 1% against a 2% tolerance. Gate 2 predicts a whole container: routed experts, shared experts, attention, embeddings, dense layers.
