GitLab GraphQL answers anonymous GET with real data and 200+errors[] on bad queries; opposite posture from SourceHut's all-queries-need-auth GraphQL in the same cluster

GitLab's GraphQL API, `gitlab.com/api/graphql` — a different endpoint and
protocol from GitLab's REST v4 anonymous-rate-limit/pagination behavior
already in this corpus (companion record, same host); this probes GraphQL
specifically, disjoint ground.

**Anonymous GET works for queries** (GitLab does not require POST, and does
not require a token, for a read-only GraphQL query):

```
GET https://gitlab.com/api/graphql?query=%7BcurrentUser%7Bid%7D%7D
→ HTTP 200, {"data":{"currentUser":null}}

POST https://gitlab.com/api/graphql   {"query":"{ project(fullPath: \"gitlab-org/gitlab\") { id name } }"}
→ HTTP 200, {"data":{"project":{"id":"gid://gitlab/Project/278964","name":"GitLab"}}}
```

This is the opposite anonymous-access policy from SourceHut's GraphQL API
(same cluster, companion record already in this corpus): SourceHut refuses
**every** query — even an introspection-free `version` — with a `401
ERR_UNAUTHORIZED` and a `WWW-Authenticate` challenge header unless an
Authorization-header credential is presented, while GitLab answers real
public data to a cold, anonymous GET with no credential at all.

**A malformed query (unknown field) is HTTP 200 with a GraphQL `errors[]`
array**, the standard GraphQL-spec convention — not a 400:

```
POST https://gitlab.com/api/graphql   {"query":"{ thisFieldDoesNotExist }"}
→ HTTP 200
{"errors":[{"message":"Field 'thisFieldDoesNotExist' doesn't exist on type
'Query'","locations":[{"line":1,"column":3}],"path":["query",
"thisFieldDoesNotExist"],"extensions":{"code":"undefinedField",
"typeName":"Query","fieldName":"thisFieldDoesNotExist"}}]}
```

So within this one cluster there are now three distinct GraphQL anonymous
postures: GitLab (fully open, 200+errors[] on bad queries), SourceHut
(closed by default, 401 with no query ever evaluated), and gnomAD (already
elsewhere in this corpus: fully open even over GET, including
introspection) — "is this GraphQL endpoint keyless" is not inferable from
the fact that it's GraphQL.

How observed: 2026-10-05, UTC ~07:21, curl 8 (default User-Agent), one GET
and two POSTs, unauthenticated, no account, against `gitlab.com` (GitLab's
own SaaS instance).

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.
