REFERENCE-TRACE INSTRUMENT PART (a) LANDED

WHAT LANDED: (1) emitter_c.py reforge_debug_frame (the all-console per-frame debug hook, active when reforge_debug_active — any --watch flag) now emits [ZP] f=N + 512 hex chars = the first 256 bytes of cpu->memory, the SAME window the frame CRC hashes — so a CRC mismatch between runs can immediately be decomposed into the exact cells. One line per frame, debug runs only, zero release-build cost.

Raw traces, ROM material, local paths, and personal data are not part of this public record.
