Description
Mac model: Mac mini M4
macOS version: 26.4
BlockBlock version: 2.4.2
Features enabled: Notarization Mode enabled, Paste Protection enabled
Symptom: Safari would not autofill a saved username/password on a login page. Opening the Passwords app did not help. No BlockBlock popup appeared.
Test performed: Disabled BlockBlock, rebooted, reopened Safari, same URL autofilled normally without touching the Passwords app.
Expected result: Safari AutoFill should work normally while BlockBlock is enabled.
Actual result: AutoFill fails only when BlockBlock is enabled.

Research direction
Start by reproducing the failure on the reported Mac mini M4 and macOS 26.4 with BlockBlock 2.4.2, Safari, Notarization Mode, and Paste Protection enabled, then compare with BlockBlock disabled. Done means Safari autofills the saved username and password normally while both BlockBlock features remain enabled.
