+## Platform services
+
+- lifecycle, contentless arguments and blocked config reads:
+  `frontend_ctx_ps5`;
+- monotonic time and bounded sleeps: RetroArch/libretro-common POSIX paths
+  backed by the pinned SDK libc; no invented PS5 ABI;
+- RetroArch worker threads: compiled out; the software profile may use SDL's
+  public pthread-backed audio primitives;
+- logging: existing RetroArch stderr/stdout path only, with file logging off;
+- VFS: generic code is linkable but the fixed PS5 wrapper supplies no content,
+  config, SRAM, state, core or data path;
+- dynamic core loading and executable-memory policy: explicitly unsupported.
+
+## Smoke core contract
+
+- no content;
+- 320x240 XRGB8888 at 60 Hz;
+- 48 kHz deterministic stereo, 800 sample frames per video frame;
+- D-pad and left analog stick offset the pattern;
+- A toggles the background;
+- Start requests clean libretro shutdown;
+- no input means unbounded deterministic operation;
+- no filesystem, networking, threads, JIT or frame-hot-path allocation.
+
+Host result for 600 no-input frames:
+
+- video FNV-1a-64: `43f920496eb5f435`;
+- audio FNV-1a-64: `a48f47dc08c56625`;
+- ASan/UBSan: pass;
+- digital- and analog-input-dependent video change: pass;
+- Start shutdown callback: pass.
+
+## Explicitly unsupported
+
+Persistent configuration, history, playlists, screenshots, saves, states,
+content loading, dynamic cores, multiple controllers, haptics, touchpad,
+gyro, lightbar, overlays, shaders and hardware-rendered cores are not silently
+reported as working.
