What's Wrong?

The "Web" tab under Past Conversations shows "No sessions yet" despite having active claude.ai sessions with a GitHub repository attached. The extension consistently returns a 404 when fetching remote sessions.

What Should Happen?

Web sessions started on claude.ai with a GitHub repo attached should appear in the Web tab. Actual Behavior:
"No sessions yet" is shown.

Additional Information

Git remote correctly resolves: https://github.com/optiscaners/Fleet-WebApp.git — extension log confirms it parsed as github.com/optiscaners/Fleet-WebApp
OAuth token is valid — direct curl to claude.ai API returns 403 (expected), not 401
Sessions on claude.ai/code clearly show the Fleet-WebApp repo attached
The 401 on fetch subscription in the logs appears immediately after OAuth completes, possibly related
