expectations of brew unbottled

[ipatch]

i've been manually updating the formula in the homebrew-freecad tap just by bumping the revisions in the formula files in hopes to get bottles built / rebuilt using the newer github hosted runner images so macos users ie. users running tahoe have prebuilt bottles, and won't need to build everything from source.

unfortunately i do not have access to a macos tahoe box arm or intel, and can only see the results from the ci runs on github.

with macos tahoe ie. macos 26 and the macos version prior, ie macos 15 i'm unable to build a bottle due to the below errors.

==> Running Formulae#formula!(freecad/freecad/fc_bundle_py312)
==> brew deps --tree --prune --annotate --include-build --include-test freecad/freecad/fc_bundle_py312
Warning: fc_bundle_py312 has unbottled dependencies, so a bottle will not be built.
Warning: No bottle built.
==> SKIPPED freecad/freecad/fc_bundle_py312

unfortunately the warning / error messages do not show output in which formula is missing a bottle. (i remember asking a similar question about this issue in the past), and for somebody who maintains a homebrew tap but doesn't have access to a box running every compatible version of macos, should brew unbottled be able to tell me which deps for a certain formula do not have bottled artifacts for the offending formula. i run arch on my primary computer and mainly use asahi for my freecad testing, but running brew unbottled on either asahi or arch i can't see to figure which bottled deps are missing for a particular os.

yeah i've been getting mixed results with brew unbottled depending on what OS i've been running the command from. ie. i get different results running the command arch linux as opposed to running the command on asahi linux. 🤷‍♂️

Is the arch Linux install x86 or arm?

the arch install is running on a x86_64 macbook pro from 2015 if that helps.

And Asahi Linux is running on Apple Silicon I guess? So that would make sense two different architectures have two different outputs

now it's seems i'm getting the same results across various linux distros 👍️ probably because several of the homebrew repos i work with have multiple remotes for the various git repos. ie. origin upstream myfork
