Describe the bug
The quota dashboard shows suspiciously identical usage percentages across multiple unrelated models that have different rate limit windows and usage patterns.

Observed behavior
In the quota dashboard:

• Gemini 2.5 Flash, Gemini 3 Flash → both show 47.5% used (52.5% remaining)
• Gemini 2.5 Pro, Gemini 3 Pro, Gemini-3.1-Pro-Preview → all show 42.7% used (57.3% remaining)
• Gemini 2.5 Flash Lite, Gemini 3.1 Flash Lite → both show 0.4% used (99.6% remaining)

Models that are architecturally distinct and have different reset windows (some reset in ~18h, others in ~21h) are displaying the exact same percentage values. This strongly suggests quota tracking may be shared or mirrored incorrectly across model groups instead of being tracked independently.

Expected behavior
Each model should track and display its own independent quota usage.

Steps to reproduce

1. Use Gemini CLI with multiple models
2. Open the quota/rate limit dashboard
3. Observe that unrelated models show identical usage percentages

Environment

• Tool: Gemini CLI 0.33.2 (official)
• Date observed: March 17, 2026

Note
This has not been verified by intentionally using models at different rates — the identical values were noticed visually. It's possible this reflects a display/aggregation bug rather than an underlying tracking issue.
