Built-in browser (cloud session linked to Mac): "Always allow" site approvals don't carry over to new conversations (follow-up to #83604)

What's Wrong?

Follow-up to #83604 (closed as not planned/stale). Still happening, now on the built-in browser rather than the Chrome extension.

I use a cloud session linked to my Mac via the Claude desktop app. I click "Always allow" on every site prompt (around 70 job-board domains). In a new conversation I have to approve every one again. Approvals hold within a single conversation but do not carry over to the next one.

What Should Happen?

Sites approved with "Always allow" should stay approved until I revoke them in Settings, across conversations.

Error Messages/Logs

Steps to Reproduce

1. Open a conversation in the desktop app linked to a Mac, using the built-in browser.
2. Visit a number of sites and click "Always allow" on each approval prompt.
3. Confirm they work for the rest of that conversation.
4. Start a new conversation and visit the same sites.
5. Every site prompts for approval again.

Additional Information

Claude Desktop 2.26454.0 on macOS Tahoe 26.1. This is the desktop app (built-in browser, cloud session linked to the Mac), not the Claude Code CLI. Impact: recurring browser tasks across the same set of sites are impractical, because each new chat needs dozens of manual approvals. Related: #83604, #74715.
