Phase 1.0D CRT entry canary

chimera_ps5_crt_entry_canary.elf is a non-RetroArch diagnostic artifact. It uses the pinned normal SDK CRT, the same ET_DYN/W^X loader class, and the same _Exit selection as the software-smoke profile.

Its fixed behavior is:

1. enter main;
2. attempt exactly one notification containing CHIMERA C1 — CRT MAIN REACHED;
3. perform one relative nanosleep of two seconds, with no interrupted-sleep retry;
4. call _Exit(0).

It contains no SDL, VideoOut, Pad, AudioOut, filesystem, networking, thread creation, listener, retry, configuration, autoload, payload launch, or installation implementation. Its complete undefined-symbol set is _Exit, memset, nanosleep, and sceKernelSendNotificationRequest; DT_NEEDED is only libSceLibcInternal.sprx and libkernel_web.sprx.

The notification ABI is copied from the local lifecycle source at commit fe08300339a13f899fb78ea404ada381a5cba87c, Git blob 654e6659c9e6f2569ddccf1c9e46ea1c62c066f3: 45 reserved bytes followed by 3,075 message bytes, passed as sceKernelSendNotificationRequest(0, &request, sizeof(request), 0). No notification ABI was inferred from a symbol name.

Static disassembly binds main at 0x0, the notification indirect call at 0x24b, _Exit at 0x23, and SDK _start at 0x290. The ELF has three LOAD segments (RX, R, RW), zero RWX segments, an empty init/fini array, no TLS, 144 relocations, and 2,512 BSS bytes.

Two clean builds produced the same 106,344-byte SHA-256 c84c0fb43392ce17abc1e7e6be38b522f1b32a681fd516d684c3dbbf7b34b743; both maps produced 96132ef015d1743606a86906c810b9e9b2832889a6d49863653b03dddb75cf07. The ELF is execution_eligible=false.
