Claude in Chrome: futuresoptix.com incorrectly blocked by domain classifier

Description

The Claude in Chrome extension (v1.0.66) blocks all interaction with futuresoptix.com, a private Streamlit trading analytics app hosted on AWS (ECS/ALB with Route 53 + ACM SSL). The domain is classified as blocked (category1/category2) by the server-side URL categorization API.

The ALB URL (Future-Servi-*.us-east-2.elb.amazonaws.com) is also blocked.

Expected Behavior

futuresoptix.com should be accessible — it's a legitimate private business tool, not a harmful site.

Actual Behavior

• screenshot, read_page, navigate, find, and all other browser tools return: "Permission denied for this action on this domain" or "Navigation to this domain is not allowed"
• The extension works fine on other sites (e.g., app.tradezella.com, github.com)

Reproduction

1. Navigate to https://futuresoptix.com in Chrome
2. Try any Claude in Chrome MCP tool on that tab
3. All tools are blocked

Environment

• Claude in Chrome v1.0.66
• Chrome on Windows 11
• Extension has host_permissions: ["<all_urls>"]
• Site access set to "On all sites" in Chrome extension settings

Request

Please whitelist futuresoptix.com and *.elb.amazonaws.com in the URL classifier, or provide a user-configurable allowlist for domains the user owns.
