lamfold-iso is original Lamco Development work (MIT OR Apache-2.0), clean-roomed
from public specifications:
ECMA-119 (ISO 9660), 4th edition (2019) — base + Joliet (normative Annex C)
IEEE P1281 (SUSP) + P1282 (Rock Ridge), Draft 1.12
El Torito Bootable CD-ROM Format Specification v1.0
Permissive implementations consulted ONLY as architecture references and as test
oracles (never copied):
iso9660-rs (morpheusx) MIT OR Apache-2.0 (no_std reader shape)
cdfs (~az1) MIT OR Apache-2.0 (Rock Ridge structure)
FreeBSD cd9660 BSD-2-Clause (in-kernel read reference)
The following GPL implementations were explicitly FENCED OFF — not read, not
transcribed — to preserve the clean-room:
GNU libcdio / libiso9660 GPLv3-or-later
Linux kernel fs/isofs GPL-2.0
genisoimage / cdrtools GPL
Test fixtures are generated with xorriso (a tool, not a source); the on-disk
bytes are data, not code.
