Minimum macOS is the major version byre's host runs (`sw_vers --productVersion` prints it); there is no back-deployment.
The transcript's scanner and spinner animate in the render server so SwiftUI never redraws around them.
The project is a Swift package built with `swift build`, not an Xcode project. It builds with Xcode's toolchain: `xcode-select --print-path` must print `/Applications/Xcode.app/Contents/Developer`. With the Command Line Tools selected while Xcode is installed, Swift Build finds two toolchains for the Command Line Tools path and picks one at random on each run; the pick is part of the build request, so every change of pick rebuilds every target.
`mac/bundle.sh` builds in one directory shared by every worktree, `~/Library/Caches/byre/build`, under a lock: SwiftPM keys a build on the package's absolute path, so a build in a fresh worktree recompiles every dependency. It copies sources in with `rsync --checksum`, which leaves unchanged files' modification times alone. It passes `--no-color-diagnostics` because `COLOR_DIAGNOSTICS` otherwise follows whether output is a terminal and is part of the build request, so agents whose shells differ would each rebuild every target in turn; `build-request.json` under `.build/out/Intermediates.noindex/XCBuildData/` shows what a build was keyed on. The server and helpers go in `Contents/Helpers`, not beside `Byre` in `Contents/MacOS`: the default APFS volume ignores case, so `byre` and `Byre` would be one file.

The font files need one thing beyond loading. The latin and latin-ext files are subsets of one variable font with the same PostScript names, so registering both and looking the font up by name finds only the latin file, and characters such as `ő` and `Ł` fall back to a system font. The app instead makes a descriptor from each file's URL, sets the weight with `CTFontDescriptorCreateCopyWithVariation`, and puts the latin-ext descriptor in the latin one's `kCTFontCascadeListAttribute`; characters in neither file then fall back to the system cascade (`→` to Menlo).
