[CRITICAL BUG] Claude Code Web: Archived sessions reappear as ACTIVE RUNNING sessions, potentially consuming tokens

Preflight Checklist

• [x] This is a single bug report (please file separate reports for different bugs)

What's Wrong?

CRITICAL: When I archive sessions in Claude Code Web and then navigate away (e.g., to a regular Claude chat) and return to Claude Code, all my archived sessions immediately reappear in the "Active" sessions list.
More critically, dozens of these sessions display the pulsing Claude logo indicator, making them appear as if they are actively running and potentially consuming tokens/usage credits.
The issue reproduces 100% of the time with these steps:

Archive sessions in Claude Code Web
Navigate to claude.ai (regular chat)
Navigate back to claude.ai/code
All archived sessions are back in the "Active" list
Many show the pulsing indicator as if actively running

This makes the archive feature completely non-functional and raises serious concerns about unauthorized resource consumption.

What Should Happen?

Expected Behavior
When sessions are manually archived:

They should move from the "Active" list to the "Archived" list
They should remain in the "Archived" list permanently unless manually unarchived
The "Active" filter should only show sessions that have not been archived
Archived sessions should NOT be running or consuming resources
Only genuinely active sessions should display the pulsing Claude logo indicator

Steps to Reproduce

Steps to Reproduce

Open Claude Code Web (claude.ai/code)
Navigate to the sessions list
Filter to show "Active" sessions
Observe old sessions that should be archived appearing in the Active list
Manually archive these sessions by flagging them as archived
Verify they appear in the "Archived" list and are removed from "Active" list
Navigate away from Claude Code (e.g., click to go to a normal Claude chat at claude.ai)
Navigate back to Claude Code Web (claude.ai/code)
Check the "Active" sessions list
Observe: The previously archived sessions have immediately reappeared in the Active list
CRITICAL Observe: Many sessions (dozens) show the pulsing Claude logo, appearing to be actively running
