Sylpheed's boot reaches its front-end TITLE shell (steady frame loop — 2219 swaps over 5B instr; XamResetInactivity/XamEnableInactivityProcessing/ XamUserGetSigninState front-end mgmt; XamInputGetCapabilities polled 8880x) but then STALLS: headless has no HID device, so GetCapabilities returns DEVICE_NOT_CONNECTED and the game loops forever waiting for a controller. It never advances to read input (XamInputGetState / XamInputGetKeystrokeEx = 0). Canary reaches the "Press A" menu because its default input drivers (xinput / winkey) present an always-connected controller. Match that: present a default always-connected, IDLE (no-buttons) virtual controller for user 0 (a console always exposes controller slots; a real gamepad under --ui still supplies actual button state — see xam_input_get_state, which prefers ui.snapshot_gamepad()). Set XENIA_NO_PAD=1 to present no controller (the raw headless no-HID trajectory). MEASURED (headless, this is not inference): with the controller connected the game advances into the interactive input-poll loop — XamInputGetKeystrokeEx 0 -> 2164 (once per frame) XamInputGetState 0 -> 2165 XamInputSetState (rumble) 0 -> 1 i.e. the "Press A" title-screen loop (attract video repeats while it polls for A), exactly the M3 milestone behavior. Visual confirmation of the on-screen "Press A" prompt is the remaining step (--ui + frame readback). GOLDEN RE-BASELINE (deliberate): a connected controller changes the guest trajectory WITHIN the 200M window (the title polls input before 200M), so both sylpheed_n200m.json and sylpheed_n2m.json are re-baselined. Change is proven ISOLATED: XENIA_NO_PAD=1 reproduces the OLD goldens byte-identical at both n. New n200m: instructions 200000203, imports 575647, draws 3208, swaps 910 (was 200000239 / 575447 / 3165 / 895 — small front-end-input increments; RTs/ shaders/textures unchanged). All 6 JIT configs match the new golden byte- identical (interp / JIT / JIT+CHAIN / +REGCACHE / REGION_MAX=1 / budget=1== interp+budget=1); 131 xenia-kernel + 21 xenia-jit tests green.
