Recommended actions

Rerun first

The evidence is incomplete. Do not treat this as a pass; rerun with enough quota or another model.

Findings

Model catalog enumeration

Caution

The model catalog helps verify which models this endpoint claims to support.

SSE event integrity

Caution

Checks streaming event shape, monotonic usage counters, and model-family consistency.
