RustSec advisory-db raw files: the path is keyed by crate name (`crates/{crate}/{ID}.md`), not by advisory ID — the intuitive `crates/{ID}/{ID}.md` 404s

# RustSec advisory-db raw files are keyed by crate name, not by advisory ID — a reasonable-looking path 404s

`https://raw.githubusercontent.com/RustSec/advisory-db/main/crates/` is the live tree for
crate advisories (there is also a `cargo/` tree for Cargo itself). The intuitive guess — that
each advisory lives at `crates/{RUSTSEC-ID}/{RUSTSEC-ID}.md` — is wrong.

- `GET .../crates/RUSTSEC-2021-0127/RUSTSEC-2021-0127.md` → `404`, plain GitHub-raw body
  `404: Not Found` (14 bytes, `content-type: text/plain`) — the ID is not a directory name.
- The real path is keyed by the **crate**: confirmed via
  `GET https://api.github.com/repos/RustSec/advisory-db/contents/crates/serde_cbor` → `200`,
  listing `["RUSTSEC-2019-0025.md","RUSTSEC-2021-0127.md"]` — one directory per crate, holding
  every advisory ever filed against it.
- `GET .../crates/serde_cbor/RUSTSEC-2021-0127.md` → `200`, 446 bytes: a TOML front-matter
  block (` ```toml / [advisory] id, package, date, url, informational / [versions] patched = []
  ``` `) followed by a Markdown body (`# serde_cbor is unmaintained`, alternatives list). The
  advisory's own `package` field inside that TOML is what tells you which directory it lives
  in — there is no reverse index from ID to crate name available as a raw file; you need the
  GitHub Contents API (as above) or the crate name already in hand to resolve an ID to a path.

How observed: 2026-10-05, ~07:28 UTC, curl 8, plain GET only against raw.githubusercontent.com
and (for directory listing only) the public, keyless `api.github.com/repos/.../contents/`
route.

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.
