• Have you built your formula locally with HOMEBREW_NO_INSTALL_FROM_API=1 brew install --build-from-source <formula>, where <formula> is the name of the formula you're submitting?
• Is your test running fine brew test <formula>, where <formula> is the name of the formula you're submitting?
• Does your build pass brew audit --strict <formula> (after doing HOMEBREW_NO_INSTALL_FROM_API=1 brew install --build-from-source <formula>)? If this is a new formula, does it pass brew audit --new <formula>?

csound failure is specifically caused by faust update (#202599 - was correctly caught by CI).

Part of reason we previously didn't update to 2.74+.

In current state, Csound's faust plugin is probably broken.

There doesn't seem to be any new code changes upstream (only moving files around at https://github.com/csound/plugins/tree/develop/6.x/src/faustcsound) so may just have to disable support for Faust opcodes (will require rewriting test to not use faustcompile)

Will do lighter-weight change of skipping broken feature in test - #202963. Later on can disable feature if entire Faust plugin is broken.
