- D48 finding in PCPortResearch.md §F: d43_convert.py does not emit bytes
(layout+remap validation only); Plan B = Python emit pass -> data/pcmodels-<region>/
RZ sidecars served via port-layer hw_address/rom_size table patch (no C
converter); Plan A kept as fallback with corrected staging guard (D_N64+D_PC<=avail)
- Moved all 23 d43_*.py investigation scripts from gitignored build-pc/ to tracked
tools_pc/ (spec is now versioned); d43_cover.py path ref updated; converter
re-run from new location: ALL CLEAN
- HANDOFF.md rewritten as two-session prompt: Session A = independent review of
Plan B (8 claims, each with falsification criterion -> finding D49), Session B =
execute (emit pass + round-trip validator, romdata plumbing, one-line hook,
pixel-assert soak); verified-facts converter spec preserved
- AGENTS.md phase status updated to D48 re-plan
