The native AppKit/Metal application is implemented and Build 8 is the current normal-play authority. The application launches its packaged emulator host in the logged-in macOS session, keeps the emulator window hidden, presents the official Android client fullscreen, and uses authenticated local EmulatorController control.
Current work is advanced graphics diagnosis, not a replacement of the native app or a direct Node/Clara emulator launch. Build 8 logging is automatic and verified; internal source-level causal attribution remains planned.
Current implementation truth is in facts.md, project.md,
and dev.md. The former implementation plan is retained at
docs/history/2026-08-31-pre-build8/TFTMACAPP.md as historical design context.
