[BUG] Claude Code blocks all models with "0% remaining" after 5 hour clock reset while /usage shows 3% session used / 97% remaining

What's Wrong?

Claude Code is blocking all prompts across multiple fresh sessions with a "session limit reached" error, despite /usage showing only 3% of the current session consumed and a 97% remaining balance. The block is reproducible across every model tier (Sonnet, Haiku, Opus, Fable), each tested in its own new tab/session.

It began blocking almost exactly after my 5 hour session reset. I hit 0% remaining the CLI seems not to acknoledge the reset upon messaging (even though /usage shows the CLI fetched the proper refilled limits from Claude's servers).

Claude web is working properly (not the same issue as https://github.com/anthropics/claude-code/issues/72680)

What Should Happen?

Gate enforcement should match the number reported by /usage. If /usage says 3% used, new prompts should be accepted.

Error Messages/Logs

You've hit your session limit · resets 4:10am (America/Los_Angeles)
/upgrade to increase your usage limit.

Steps to Reproduce

1. Hit a session limit block in Claude Code (error shown: "You've hit your session limit · resets 4:10am (America/Los_Angeles)")
2. Run /usage — shows Current session: 3% used, resets 4:10am; Current week (all models): 31% used; Current week (Fable): 54% used
3. Open new Claude Code sessions with Sonnet, Haiku, Opus, and Fable individually
4. Every model blocks immediately with a session-limit error, despite step 2's numbers indicating ample headroom
