What's Wrong?

Summary

In the /usage dialog, the quota bars render correctly for a split second on mount and then flip to a broken layout. Once in the broken state, the "Current session" bar is missing entirely, the "Current week (all models)" bar is squeezed onto the same line as the Resets … text instead of appearing on its own line, and the "Extra usage" line has the trailing word used jammed onto the reset text with no separator or bar. The "Current week (Sonnet only)" bar, which has no reset text preceding it, renders correctly. Resizing the terminal has no effect.

Reproduces in every terminal I've tried. Screenshot and video attached.

What Should Happen?

Each section ("Current session", "Current week (all models)", "Current week (Sonnet only)", "Extra usage") should render as:

• Header label
• Resets … line
• Progress bar on its own line
• N% used (or $X / $Y spent) to the right of the bar

Steps to Reproduce

1. Open Claude Code in any terminal
2. Run /usage
3. Switch to the Usage tab
4. Watch the first frame render — bars are correct — then the dialog re-renders into the broken state

Notes (written by claude)

The only section that survives the re-render correctly is "Current week (Sonnet only)", which is also the only section without a Resets … line immediately preceding the bar. That suggests the post-mount layout pass isn't reserving bar width before laying out the reset-text line, so the bar gets pushed onto the wrong line or dropped when the Resets … text is long (full date + timezone). Because the bug is terminal-agnostic, it's almost certainly in the Ink/React TUI layout logic rather than terminal emulation.
