Platform rule due for review

Homebrew non-official tap trust requirement

Homebrew requires explicit trust for non-official taps by default while bounding failures to commands that load untrusted code and preserving item-only trust for fully qualified installs.

RuleRoster is independent and is not affiliated with or endorsed by Homebrew.

Direct answer

What is the rule?

Non-official Homebrew taps require explicit trust by default since Homebrew 6.0.0. Only commands that need to load an untrusted tap or item fail until relevant trust is granted; installing a fully qualified formula or cask trusts only that item, not the whole tap. The temporary opt-out is not recommended and is not a permanent exception.
