MACOSX_DEPLOYMENT_TARGET was 27.0 across all 6 build configs (app +
both test targets) - an artifact of Xcode defaulting it to match the
beta SDK this is developed against, not an actual code requirement.
At 27.0 the app would only install for people running a macOS beta
that doesn't even exist for the general public yet.
14.0 is the real floor, already documented as the target in
CLAUDE.md ("macOS 14+ minimum, needed for mature AttributedString/
TextKit 2 APIs") and required independently by @Observable/SwiftData,
which are used throughout (SessionStore, StarStore, TipJarStore,
OfflineCacheStore, APIFailureCenter, etc.). Everything else added
this session - StoreKit 2, ImageRenderer, requestReview, CryptoKit -
is available well before 14, so nothing pushes the floor higher.
README's "macOS 27+" end-user requirement corrected to 14+ to match
(the "Xcode 27+" line just above it is a separate, still-accurate
build-from-source requirement, left alone).
Not compiler-verified against the 14.0 SDK - this project has never
actually been built with this deployment target before (always 27.0
during this session's development), so a real Xcode build now may
surface "only available in macOS 15+/26+" errors on any API used
without realizing it needed newer than 14. Needs an actual build
before submission, not just a lower number in the project file.
