The name is a sheepfold —\nthe enclosure holding the *flock* of formats — and the layered, recursive\nstructure it reads. Authoritative spec: `the lamfold design spec`.\n\n## Crates\n\n| Crate | Role | Status |\n| ----- | ---- | ------ |\n| [`crates/lamfold`](crates/lamfold) | **substrate core** — codec registry (deflate/lz4/zstd/xz/lzo), immutable-block cache, bounded zero-copy parse + read-cap, `FoldFrontend` trait, the shepherd (`Verifier` seam + native fs-verity Merkle) | ✅ substrate + shepherd (21 tests) |\n| [`crates/lamfold-iso`](crates/lamfold-iso) | **optical frontend** — ISO9660 + Rock Ridge + Joliet + El Torito + zisofs | ✅ complete |\n| [`crates/lamfold-udf`](crates/lamfold-udf) | **UDF frontend** — ECMA-167 / OSTA 1.02 read | ✅ base (real mkudffs image) |\n| [`crates/lamfold-squash`](crates/lamfold-squash) | **compressed frontend** — SquashFS 4.0 (gzip/xz/zstd/lz4/lzo), the live-ISO root | ✅ complete (real mksquashfs image) |\n| [`crates/lamfold-erofs`](crates/lamfold-erofs) | **forward-standard frontend** — EROFS (uncompressed) + the shepherd (fs-verity block gating) | ✅ complete (real mkfs.erofs image) |\n| [`crates/lamfold-cramfs`](crates/lamfold-cramfs) | **legacy compressed frontend** — cramfs (per-page zlib) | ✅ complete (real mkcramfs image) |\n| [`crates/lamfold-romfs`](crates/lamfold-romfs) | **minimal-embedded frontend** — Linux romfs (`-rom1fs-`) | ✅ complete (real genromfs image) |\n| [`crates/lamfold-cpio`](crates/lamfold-cpio) | **initramfs frontend** — newc cpio tree (reuses `cpio_reader`) | ✅ complete (real cpio archive) |\n\nEvery frontend is a thin member that depends on `lamfold` (the namesake core,\nlike the `lamco-wayland` crate within the `lamco-wayland` workspace) and contains\n*only* on-disk structure parsing — codecs, caching, bounded parse, and\nverification all come from the substrate. Each member publishes as its own crate\n(Debian/crates.io granularity) while versioning and CI'ing together.\n\n## Use\n\nNot yet on crates.io — development is in progress. Until the first release,\ndepend on the member you need via this Git repository:\n\n```toml\n# the optical frontend (ISO9660 + Rock Ridge / Joliet / El Torito / zisofs)\nlamfold-iso   = { git = \"https://github.com/lamco-admin/lamfold\", default-features = false, features = [\"zisofs\"] }\n# the EROFS frontend + the shepherd (fs-verity integrity)\nlamfold-erofs = { git = \"https://github.com/lamco-admin/lamfold\", default-features = false, features = [\"verity\"] }\n# …and lamfold-udf / -squash / -cramfs / -romfs / -cpio, plus the `lamfold` substrate core.\n```\n\nOnce published, the same members will be available as crates.io versions\n(`lamfold-iso = \"X.Y.Z\"`, …) — see each crate's `documentation` link.\n\n## Build / test (whole workspace)\n\n```bash\ncargo test                                   # all members\ncargo build --no-default-features            # no_std check\ncargo clippy --all-targets -- -D warnings\n```\n\nThe pinned, all-permissive dependency set lives once in the workspace root's\n`[workspace.dependencies]` (zero copyleft in the tree).
