ADR-0012: Phase-1.0J first-frame identity
- Status: accepted for offline diagnostic construction
- Date: 2026-07-22
- Decision:
FIRST_FRAME_INDEX_ZERO_SOURCE_CONSISTENCY_ONLY
Context
The consumed Phase-1.0H run submitted the diagnostic buffer with
sceVideoOutSubmitFlip(handle, 0, 1, 0) and received -1. The diagnostic
helper used buffer zero, while the patched normal SDL update path started its
frame counter at one. The public PS5 SDL source at commit
0baf4ac49382b537ba449901b5b6d0d189bb1fbb starts that normal counter at
zero. Phase 1.0I classified the mismatch as a strong source candidate, not a
proven firmware root cause.
Decision
The Phase-1.0J SDL overlay defines one compile-time source of truth,
CHIMERA_PS5_FIRST_FRAME_INDEX, with value zero. The early diagnostic copy,
the early diagnostic submit and the normal update counter all derive their
initial index from that macro.
Zero is selected because it preserves the already-audited diagnostic tuple and agrees with the public SDL source. It is not selected on the basis of an unpublished ABI or an inferred firmware requirement.
Consequences
The internal zero-versus-one inconsistency is removed and can be checked in source, linker-map and disassembly evidence. This decision does not prove that buffer zero is accepted on firmware 9.60, that the fourth flip argument has the required semantics, or that the old mismatch caused the Phase-1.0H failure.
Phase 1.0J remains an offline artifact phase. A separately reviewed exact artifact and new explicit permission would be required before any connection, transfer, result reception or execution.
