# Disallowed macros

### Rule

Pages must not use macros that are explicitly blocked by governance or security policy. Remove any prohibited macros and replace with approved alternatives.

### Why it matters

Blocks unauthorized functionality. Disallowed macros may exfiltrate data, add unreviewed code paths, or degrade performance and reliability.
