[BUG][BUG] Claude in Chrome blocks platform.thetrustconstruct.com (own SaaS production domain) — server-side org_policy: "block" on personal account with no MDM

What's Wrong?

The Claude in Chrome extension blocks navigation to platform.thetrustconstruct.com — the production application subdomain of my own SaaS product — with the message:

Can't access this page This site is blocked by your organization's policy.

What Should Happen?

Claude in Chrome should allow navigation to my own production SaaS domain. No organization, MDM, or managed Chrome policy exists on this machine — block is enforced server-side by Anthropic's classification API.
