/**
|
|
* Tests for open-sse/services/usage.ts — Antigravity quota parsing.
|
|
*
|
|
* Verifies that remainingFraction is correctly parsed:
|
|
* - undefined → 0% remaining (exhausted quota)
|
|
* - 0 → 0% remaining (exhausted quota, explicit)
|
|
* - 1.0 → 100% remaining (full quota)
|
|
* - 1.0 without resetTime → unlimited (e.g. tab-completion)
|
|
* - 0.5 → 50% remaining (partial quota)
