M13-02E Status

status: done task: permission default-minimization and unknown-permission blocking updated: 2026-08-18 America/New_York enablingTask: false parityStateChange: false

Scope

resolveScriptPermissions now grants an empty set by default and only grants an explicitly requested permission when it is already declared by the script manifest. Unknown, duplicate or undeclared requests return SCRIPT_POLICY_DENIED; manifest declarations still reject unknown permissions during parsing. This task adds no execution capability.
