【Our read】

1. This is the broader-access confirmation the patrol watched for; Ultra quota / Antigravity IDs / third-party listings were side signals—primary blogs and the CEO post are now on record.

2. Distinct from site e/691 (Sept 30 limited preview): this piece is global GA, channels and pricing.

3. Still open: free-tier timing, independent evals vs launch claims, Cloud region and quota detail.
