lamfold-udf — third-party attribution
lamfold-udf is original Lamco Development work (MIT OR Apache-2.0), clean-roomed
from the freely-available specifications:
ECMA-167 (Volume and File Structure for Write-Once and Rewritable Media)
OSTA Universal Disk Format (UDF) 1.02
Permissive implementations consulted ONLY as architecture references and as test
oracles (never copied):
hadris-udf MIT (no_std UDF 1.02 read shape)
oxideav-dvd MIT (clean-room UDF reference)
The GPL implementations were FENCED OFF — not read, not transcribed:
Linux kernel fs/udf GPL-2.0 (ecma_167.h / osta_udf.h struct headers)
udftools / mkudffs GPL-2
Test fixtures are generated with mkudffs (a tool, not a source); the on-disk
bytes are data, not code.
