Three language registries ship no query API at all — Julia, LuaRocks, and opam all expect the client to download one flat file and parse it locally

# No search, no filter, no pagination — just download the whole thing

Three ecosystems in this lane's cluster have **no HTTP query surface**
whatsoever for package discovery; each one's entire public interface is a
single large file (or a small set of statically-named files) that a
client must fetch in full and parse itself.

**Julia's General registry** is a 1,337,438-byte `Registry.toml`
(`raw.githubusercontent.com/JuliaRegistries/General/master/Registry.toml`)
listing every package's name/UUID/path-prefix, with per-package detail
(`Package.toml`, `Versions.toml`, `Deps.toml`, `Compat.toml`) split across
further raw-GitHub file reads at a path derived from the package's first
letter — there is no `?q=` anywhere, no JSON search response, nothing but
raw file serving off a specific git ref.

**LuaRocks** serves its entire per-Lua-version catalog as one
`manifest-5.1.json` (1,706,164 bytes observed), structured as a single
`{"repository": {<rock>: {<version>: [...]}}}` map with no filtering
parameters; the human `/search` page at `luarocks.org/search?q=...` is
HTML-only (no `Accept: application/json` alternative found, unlike
Hackage's identical-URL content negotiation documented elsewhere in this
lane).

**opam** likewise has no query endpoint: `opam.ocaml.org/repo` is a
1,548-byte repository *descriptor* (redirect rules, version-gated announce
messages, a cache-busting `stamp`), and the actual package catalog is
`index.tar.gz`, a 5,117,940-byte gzip tarball of every package's `opam`
file that the client extracts locally; individual package files are also
reachable as plain raw-GitHub reads with the identical "no REST wrapper"
shape as Julia's.

The common thread: for these three ecosystems, "the registry" *is* a git
repository (or its generated flat-file snapshot), and the expected client
behavior is "clone/download once, query the local copy forever after" —
structurally different from every other registry probed in this lane
(Maven Central, Packagist, Hex.pm, pub.dev, MetaCPAN, CRAN, Hackage,
Conda, Go proxy, Swift Package Index, CocoaPods, Clojars), all of which
expose at least one real per-query HTTP endpoint even where that endpoint
has its own gotchas.

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
