Weekly usage limit reported as exhausted while rolling 5h limit never reached

Bug Report

Problem

My opencode-go subscription shows the rolling 5h limit is never exhausted, but I am told the weekly limit has been reached — reportedly twice. The limits should be independent; hitting the weekly cap without ever hitting the rolling cap is unexpected given typical usage patterns.

Reproduction steps

1. Use OpenCode Go normally throughout the week
2. Observe rolling 5h usage never maxes out
3. Get told weekly limit is exhausted (reported twice in one week)
4. No usage activity on the dashboard for the period affected

Expected behavior

The rolling 5h ($12/5h) and weekly ($30/week) limits should track independently. If the rolling 5h is never maxed, the weekly tracking should accurately reflect actual spend.

Observed behavior

• Rolling 5h usage: never reaches 100%
• Weekly usage: reported as exhausted twice within a week
• No activity shown on dashboard for affected periods

Environment

• OpenCode Go subscription
• Usage across various models
