Schema Inaccuracy

The description defines two pairs of templated paths that differ only in the name of the last template expression:

The OpenAPI Specification (3.0.3, Paths Object) says: "Templated paths with the same hierarchy but different templated names MUST NOT exist as they are identical." Each pair above has the same hierarchy, so a router or generator that matches requests by path template sees one path with two definitions. (/repos/{owner}/{repo}/attestations/{subject_digest} has no such counterpart.)

Checked at commit 755ee33, descriptions/api.github.com/api.github.com.json.

Expected

Each hierarchy appears once in paths. For example, one path item per pair with a single template expression name, holding both the GET and the DELETE operation and declaring the parameter at the operation level.

Reproduction Steps

curl -sL https://raw.githubusercontent.com/github/rest-api-description/755ee33b4a81d51f6f07a902cce26cbec3b822f2/descriptions/api.github.com/api.github.com.json -o api.github.com.json
node -e '
const paths = Object.keys(JSON.parse(require("fs").readFileSync("api.github.com.json","utf8")).paths);
const seen = new Map();
for (const p of paths) { const k = p.replace(/\{[^}]+\}/g, "{}"); if (seen.has(k)) console.log(seen.get(k), "<->", p); else seen.set(k, p); }'

Output:

/orgs/{org}/attestations/{attestation_id} <-> /orgs/{org}/attestations/{subject_digest}
/users/{username}/attestations/{attestation_id} <-> /users/{username}/attestations/{subject_digest}
