- 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
