MoE without auxiliary loss

Check R15. Runs in the editor as you build, in CI through the GitHub Action, and over the wire at POST /api/v1/check. Milliseconds, before any GPU is billed.

info pattern R15
TriggerModel contains an MoE layer but no auxiliary load-balance loss is referenced.
WhyWithout an aux loss, experts collapse into a few dominant ones. Most papers add a 0.01 weight router-balance term.

Why it is not a lint you can ignore

A structural mistake does not fail at review time and it does not fail at import time. It fails when the module is constructed on the training node, after the job was queued and the dataset was downloaded. That is why this runs before the spend and not after it.
