Phase 1.0C/D/E device observations

Evidence class: operator-observed, artifact-bound hardware evidence.

Three separately authorized one-shot runs have occurred. Every authorization is consumed and none authorizes another connection, transfer or execution.

Run	Exact artifact	Host action	Operator observation	Proven boundary
A	chimera_ps5_crt_entry_canary.elf, 106,344 bytes, c84c0fb43392ce17abc1e7e6be38b522f1b32a681fd516d684c3dbbf7b34b743	one connection and one complete send; no retry	CHIMERA C1 — CRT MAIN REACHED visibly appeared	elfldr reached SDK _start, CRT completed, main and the notification ABI executed on firmware 9.60
B	retroarch_ps5_early_diag.elf, 1,844,664 bytes, 092bcabc0f8717a648030c592aa0dc900f878952fb14ee453851a29f298ea7ee	one connection and one complete send; no retry	one notification appeared too briefly to identify its D-code; console remained responsive	some notification-producing payload code ran, but the exact D-stage is UNCLASSIFIED
C	retroarch_ps5_result_diag.elf, 1,844,880 bytes, 1049c78099a60b472a3fb0e2999e3393b6ad76337a28532a7e53872e7772dedf	one connection, complete send, write-half-close and bounded receive; no retry/reconnect	three binary frames validated, then remote EOF	D00 main, D01 platform-init begin and D02 platform-init result 0; inherited stdout worked; incomplete before D03

The ignored local host traces bind each send to its artifact and show no retry. They contain the session address and are deliberately not committed. RUN C's trace is 1,795 bytes with SHA-256 4ff27a0eac48283cdc4c7ff964226def2689e808e3adea6594d0e77674a676f0. It records one connect, one sendall, one shutdown(SHUT_WR), five receives, 3,413 received bytes, 3,221 discarded non-frame stdout bytes, remote EOF, zero parser errors, zero retries and zero reconnects.

The three valid frames had sequences 1-3 and CRC-32 values 93f81433, f2b975e4 and 69173d14. All reported notification result 0; D02 carried raw0=0. In source, D03 is emitted at entry to sdl2_gfx_init(). Its absence means SDL-init begin, SDL/VideoOut, first flip, rendering, terminal status, cleanup and safe exit remain UNPROVEN. The unretained stdout bytes cannot be used to infer why execution ended before D03.
