lamfold-udf

The UDF frontend of the lamfold read-only media stack — clean-room UDF (ECMA-167 / OSTA 1.02) read.

Reads over a lamfold::BlockSource and implements lamfold::FoldFrontend, so it composes through dispatch_fs_over_source and co-resides with lamfold-iso on UDF-Bridge optical media. Spec: the lamfold design spec §4.

Status — UDF base

Capability State
Descriptor chain (AVDP → VDS → Partition + Logical Volume → File Set → root ICB) ✅ done + tested
File Entry (tag 261) inodes; File Identifier Descriptors (directories) ✅ done + tested
Data: inline / short_ad / long_ad; UCS-2 + Latin-1 names ✅ done + tested
Extended File Entry (266), metadata/sparable/VAT partition maps (UDF 2.x) ⏳ deferred
extended_ad, allocation-extent continuation, symlink path resolution ⏳ future

Verified against a real mkudffs --udfrev=0x0102 image (populated via loop mount): probe, tree walk, inline small files, a nested directory, and a long_ad-extent file (5000 bytes, full + mid-extent reads). Builds default + --no-default-features (no_std); #![forbid(unsafe_code)].
