"""D125 diagnostic: does the propDefs blob in the *emitted* pccg sidecar
|
|
(after RZ round-trip) byte-match tools_pc/d88_propdefs.convert_stream()?
|
|
|
|
Tests the M-14 claim that the RAM propDefs is "zeros/garbage after record 0".
|
|
If this script says MATCH, the corruption is downstream of the sidecar
|
|
(runtime rebase / bank alloc / sizepropdef walk); if MISMATCH, it is in
|
|
d88_emit.py's emit/placement or the RZ recompress.
