+# Proposed first PS5 smoke test (not authorized)
+
+This is a review package only. It is not a sender, execution package or device
+instruction and it grants no authority.
+
+## Candidate
+
+The first useful device test would use the exact audited
+`retroarch_ps5_software.elf`, not the headless ELF. The headless static core
+has no observable result channel and intentionally runs indefinitely with null
+input. The software candidate can provide visible, audible and controller
+evidence and can request a clean shutdown.
+
+Before any action, a later task must bind:
+
+- source commit `ca1b45680577befc743e1c92fa40687e1b1745e7`;
+- the 3318432-byte ELF with SHA-256
+  `7beb09592404b5c1fb4161c632171d2901f3715db26e59458998690e8c49f3fc`;
+- firmware text `9.60`;
+- a manual, non-autoload, non-installing one-shot loader route;
+- an independently reviewed recovery path;
+- a 100 ms flip timeout in the linked SDL object;
+- no automatic retry;
+- one explicit artifact-specific transfer authorization and one explicit
+  execution authorization.
+
+## Exact proposed one-shot scope
+
+1. Verify the local ELF hash against the reviewed manifest.
+2. Verify autoload remains off and no live component will be replaced.
+3. Transfer only that one ELF to a non-persistent one-shot loader path.
+4. Execute once with no content and no arguments.
+5. Observe whether a 320x240 moving pattern is presented through RGUI/SDL.
+6. Observe bounded 48 kHz stereo test audio.
+7. Check one controller: D-pad and left stick change pattern position and A
+   changes its background.
+8. Press Start once and observe whether RetroArch returns cleanly.
+9. Do not retry automatically. On crash, hang, missing output, timeout or
+   unexpected filesystem/service behaviour, stop and use the separately
+   reviewed recovery action.
+10. Hash and preserve host-side logs/transcript; do not infer success for
+    unobserved subsystems.
+
+## Explicit technical effects to accept later
+
+The SDK CRT performs its previously documented bounded runtime initialization.
+The software profile opens user/system service, VideoOut, Pad and AudioOut,
+allocates heap/direct-memory buffers, creates SDL audio/thread primitives,
+submits VideoOut flips, waits on an equeue with a 100 ms timeout, polls input
+and writes audio. Logs, scheduler activity, process accounting and caches may
+change. These are functional runtime effects, not a side-effect-free probe.
+
+## Remaining risks
+
+- loader entry/return and firmware-9.60 lifecycle remain hardware-unproven;
+- VideoOut ownership or direct-memory assumptions may fail;
+- the public SDL backend's partial-init cleanup has not been observed;
+- a timeout may return an error but higher-level shutdown still needs proof;
+- audio output is blocking and underrun/overrun statistics are absent;
+- controller mappings/deadzone need device validation;
+- generic RetroArch write-capable code remains in the ELF even though the
+  fixed first-run path blocks persistent writes;
+- a crash or hang may require a reboot/new jailbreak session.
+
+No transfer or execution may occur on the basis of this document alone.
