# Phase 1.0P terminal ordering analysis
|
|
|
|
The Phase-1.0O order `D07, D12, D04` is deterministic in the bound source; it
|
|
is not evidence of network reordering.
|
|
|
|
1. The early diagnostic detects the nonzero submit result and enters SDL's
|
|
`framebuffer_fail` path.
|
|
2. `chimera_ps5_smoke_video_error(E104)` requests failure shutdown.
|
|
3. The shutdown request synchronously emits D12, which the current stream
|
|
helper marks terminal.
|
|
4. `PS5_VideoInit` then returns failure to `sdl2_gfx.c`.
|
|
5. The caller emits D04 with the SDL initialization result `-1`.
|
|
|
|
D12 and D04 arrived in the same host receive block. The runner intentionally
|
|
requires the last parsed frame to be terminal, so D04 correctly prevented a
|
|
successful terminal classification. The individual CRC-valid frames remain
|
|
runtime evidence; successful cleanup and safe exit do not.
|
|
|
|
Accepting any earlier terminal frame would incorrectly promote a shutdown
|
|
request into lifecycle completion. A future protocol must instead use a new
|
|
magic and a distinct final stage emitted only after D04 and bounded cleanup or
|
|
return evidence. D12 may remain failure/shutdown-request evidence, but must not
|
|
serve as the lifecycle terminal on this error path. This is a design
|
|
requirement only: Phase 1.0P changes neither target code nor the host parser.
