`zbase32 0.1.2` is LGPL-3.0+ — the only hard copyleft dependency in the whole
Rust graph and the last remaining blocker for the MIT release
(docs/LICENSE-COMPLIANCE-AUDIT.md §2). Statically linking LGPL code into a Rust
binary obliges us to ship relinkable objects, which is impractical for a node
image.
The audit offered two routes: the MIT `z32` crate, or an original
implementation. Took the latter — z-base-32 is an alphabet substitution over a
bit stream, so ~60 lines removes the blocker while adding *zero* new
dependencies rather than trading one supply-chain entry for another.
**Byte-compatibility was the requirement, not a nice-to-have.** A `did:dht`
identifier IS this encoding of an Ed25519 public key, so any drift would
silently rotate every node's DID and orphan its already-published DHT records.
So the semantics were not guessed: I read the vendored zbase32-0.1.2 source to
extract exactly what `encode_full_bytes` and `decode_full_bytes_str` do —
including that decode truncates to the next lower byte boundary, which is why a
52-character string round-trips to 32 bytes while discarding 4 padding bits.
A model implementation was then validated against three independent sources
before any Rust was written, all five vectors agreeing:
encode(b"testdata", 64) -> qt1zg7drcf4gn (crate doctest)
encode_full_bytes("Just an…") -> jj4zg7bycfzn… (crate doctest)
decode_full_bytes("qb1ze3m1") -> b"peter" (crate doctest)
encode([f0,bf,c7]) -> 6n9hq (Zimmermann spec)
encode([d4,7a,04]) -> 4t7ye (Zimmermann spec)
The module pins all of those plus four known 32-byte keys, a 0..40-byte
round-trip sweep, a 52-char/round-trip check over 64 keys, rejection of the
characters z-base-32 deliberately omits (`l`, `v`, `2`, `0`) and of non-ASCII,
and an alphabet/decode-table consistency check so the compile-time reverse table
can't drift from the alphabet.
`did_dht.rs` gains `did_for_a_known_key_is_stable`, which pins the full
identifier string for a known key — the regression that would actually hurt,
asserted at the call site that gives the string its meaning.
Dropped from Cargo.toml and Cargo.lock (7 lines); no other user in the tree.
Verified: 28/28 network tests pass, zero copyleft crates remain in the lockfile.

The audit has claimed since 2026-07-23 that these were git-rm'd. They weren't —
only the web/dist copies went, and all of them were still tracked at HEAD nearly
three weeks later, in a repo about to be published under MIT.
Deleted (~40.7 MB):
neode-ui/public/assets/fonts/Courier_New/{CourierNew-Bold,CourierNew-Regular}.ttf
neode-ui/public/assets/fonts/Benton_Sans/BentonSans-Regular.otf
neode-ui/public/assets/fonts/Redacted/redacted.regular.ttf
neode-ui/public/packages/wireguard.apk (17 MB)
neode-ui/public/packages/atob.s9pk (23 MB)
Courier New is Monotype proprietary and Benton Sans is a commercial Font Bureau
typeface — neither is redistributable. wireguard.apk carries GPL-2.0 libwg
components, so shipping it triggers a source offer. atob.s9pk is a Start9
package of unknown license. Redacted's upstream is OFL-1.1 but no license text
was shipped; deleting was cheaper than sourcing it, since it was unused.
Verified unreferenced before deleting, not after:
- Every @font-face rule in the tree (2 in src/style.css, 2 in
public/entropy/index.html) loads Montserrat. None of these files was ever
loaded by CSS.
- The three `Courier New` hits (tailwind.config.js `mono`, two public HTML
font-family lists) name the *system* font as a fallback — they are not
@font-face sources, so rendering is unchanged.
- wireguard.apk and atob.s9pk have zero references in any tracked file.
- These live under neode-ui/public/, which Vite copies verbatim rather than
resolving, so their absence cannot break a build.
Deliberately kept: neode-ui/public/packages/archipelago-companion.apk, which IS
live (staged by .githooks/pre-push, the Android release flow, and the in-app
pairing QR); Montserrat (OFL.txt) and Open Sans (LICENSE.txt), both properly
licensed; and neode-ui/test-install.sh, which the same audit line listed but
which is not a licensing concern.
Audit updated: §1 and §3's font/package items marked closed, the false DONE
entry rewritten as a history note rather than deleted — a DONE line here is a
claim and should be re-verified with git ls-tree, which is exactly the lesson.
§2 (zbase32, LGPL-3.0+) is now the last hard blocker.
Side effect: ~40 MB off the frontend OTA tarball.

The 2026-07-23 status block lists as DONE: "Deleted: Courier_New/, Benton_Sans/,
Redacted/ fonts; wireguard.apk; atob.s9pk; obsolete test-install.sh (all
git-rm'd)". All seven are still tracked at HEAD and present on disk. Only the
web/dist copies went; the sources never did.
git ls-tree -r HEAD --name-only | grep -iE 'Courier_New|Benton_Sans|Redacted/|wireguard.apk|atob.s9pk'
That means a repo about to be published under MIT still carries a commercial
Font Bureau typeface and two proprietary Monotype fonts — precisely what §3 of
this audit says must not ship. An audit that reports a blocker as closed is
worse than one that never checked, so the entry is now struck through with the
file list and the verification command inline.
Deleting them is safe and I checked before saying so: nothing references the
font *files* (the three `Courier New` hits are CSS font-family fallbacks naming
the system font, not @font-face sources), and wireguard.apk / atob.s9pk have
zero references anywhere in the tree. Left the deletion itself to the operator —
it is 40 MB of tracked binaries and outside a docs pass. Removing them also
takes 40 MB off the frontend OTA tarball, which is a separate open item.
Also re-verified the rest of the remaining list:
- `zbase32` (LGPL-3.0+) is still a direct dep (Cargo.toml:113, did_dht.rs:40,49).
Still the only hard copyleft blocker.
- LICENSE (MIT), NOTICE and both THIRD-PARTY-LICENSES inventories are present —
so the headline "no license of its own" is closed; softened the verdict to say
which blockers remain rather than leaving a stale "not releasable as-is".
- The four StartOS-derived crates still exist; flagged that KEY-05 cites
core/models, so that one needs review rather than a blind delete.
- Item 6 (git filter-repo history purge) is superseded — the launch plan is a
fresh-history publish, so there is no history to rewrite.
