Checks / performance
Very large activation tensor
Check R14. 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.

R14
| Trigger | Any layer's estimated activation tensor exceeds 50 M elements (~200 MB per sample at float32). |
|---|---|
| Why | Activations live in GPU memory through the backward pass. One bloated layer forces tiny batch sizes or OOM. |
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.
