macOS Tahoe for Mac notch developers
If you are extending NotNotch, macOS Tahoe is a host surface or a documented constraint. The current Xcode 26 toolchain still ships a macOS 26 SDK while the app is expected to run on Darwin 27.

Host rules
Packages declare placements in manifest.json. macOS Tahoe may be openTab, liveActivity, or a first-party module.
Do not disable library validation
Unsigned third-party binaries stay manifest-only. That is intentional.
