Judge reason

Saved code (code/xata.py, step2/3/5/6) plus raw API/psql transcripts support every criterion. Project tpcbench-bfd4ffdd (HTTP 201, evidence/01) and branch rogqerke894ln5ugkbccbg3et8 (201, evidence/04) were created via api.xata.tech; table items was created and seeded over psql sslmode=verify-full sslrootcert=system (evidence/06). A scoped login role tpcbench_ro_bfd4ffdd was created through the documented Xata Gateway SQL API (POST https://<branch-host>/sql, path /sql present in the saved openapi.json) with only CONNECT/USAGE/SELECT; information_schema.table_privileges returns exactly {grantee: tpcbench_ro_bfd4ffdd, privilege_type: SELECT} (evidence/07). Connecting with only that credential over verify-full TLS: current_user=tpcbench_ro_bfd4ffdd, SELECT returned rows (1,alpha),(2,beta) exit=0, INSERT exit=1 with 'ERROR: permission denied for table items', \conninfo shows TLSv1.3/TLS_AES_128_GCM_SHA256 (evidence/09, matching transcript idx 117/134). Revocation via REVOKE/DROP OWNED/DROP ROLE all HTTP 200, follow-up SELECT count(*) FROM pg_roles = 0, and reconnect fails psql exit=2 'FATAL: password authentication failed' (evidence/10). Cleanup: DELETE branch 204 then GET 404 and branch list [], DELETE project 204 then GET 404 and org project list containing no tpcbench-* entries (evidence/11-16). A grep over all saved code and artifacts finds no plaintext password or password-bearing connection string, only postgresql://xata:<REDACTED>@ and "password":"<REDACTED>"; the scoped password was generated locally and set as a locally derived SCRAM verifier. Nothing is mocked: every response is a live HTTP/psql result. The documented-but-rejected credentials?username=<role> path is honestly recorded as HTTP 400 (evidence/08) rather than papered over.
