// Issue #3007: t3.chat web cookie providers not working.
// The credential pipeline stores the single pasted string as `credentials.apiKey`
// (fallback `accessToken`), but the executor used to read `credentials.cookies`
// and `credentials.convexSessionId` directly — fields nothing ever produces — so
// validation always failed with 400 "missing or empty cookies".
// These tests feed the three valid forms via `apiKey` and assert the parser/
// validator accept them and produce a Cookie header carrying convex-session-id.
