#요약 (AI 작성)

maru의 PTY 리더·서피스 런타임과 렌더러 계약을 세운 날입니다. PTY reader 생명주기·bounded 큐·self-pipe wake + kqueue NOTE_EXIT, HUP→TERM→KILL 종료 정책, runtime event pump와 surface runtime 라우팅, 헤드리스 PTY 데모를 붙이고, 렌더러는 DrawList·glyph atlas·fake glyph layout 계약과 커서 dirty 계약을 정리했습니다.

suji는 embedded CPython 3.13 백엔드를 1급 시민으로 올려 iOS·Android 실기 e2e 5/5, packaged .app/CLI 번들과 PYTHONHOME 자립 해석, PyPI(suji-stubs) 발행까지 마쳤습니다. zntc는 Persistent Linker RFC(#4176)로 dev HMR link를 증분화해 reuse-hit에서 rename guard·symbol refcount·namespace access를 변경분 한정으로 줄이는 등 링커 단계 성능을 대폭 절감했습니다.
