What's Wrong?

Summary

My account is trapped in a server-side background execution loop on Anthropic's backend. When my 5-hour or weekly Claude Max usage windows reset, the quota instantly jumps to 40%–100% within minutes without any local action or input on my end.

Steps Taken / System Verification

1. Sessions Cleared: Revoked all active sessions under claude.ai Settings > Security.
2. Local Environment Purged: Completely uninstalled Claude Desktop App and Claude Code CLI tools (claude logout performed, ~/.claude directory completely removed). Tested leaving all physical devices turned off during a window reset.
3. Console Inspected: Verified console.anthropic.com is completely clean — 0 API keys, 0 active sessions, 0 deployments, 0 active agents.
4. Behavior Persists: Despite zero local software running and zero active logins/keys, the 5-hour reset triggers an immediate 40–100% limit exhaustion on the server side.

Expected Behavior

A completely idle account with no active sessions or local CLI processes should remain at 0% usage after a quota window reset.

Actual Behavior

The backend server triggers an orphaned context/compaction loop tied to my account ID, instantly burning through the Max subscription limit.

Additional Context

• Account Tier: Claude Max
• Reached out via email support 3+ times over the past month with no response or resolution.
• Requesting an internal infrastructure team member to inspect my account state ID and flush any hanging server-side agent/session contexts.

What Should Happen?

i should be able to use my claude max account when i like without it randomly using up all my 5 hour limit
