// Issue 1563: no tool read a forge team's members and rights, so the build keys' read-only user (nox-builder, team
// builders, ADR 0466 §3) could not be checked live. The tools' token answers /orgs/novox/teams 403; the read goes with
// the administrator's login, GET only.
//
// The answers below keep the shape of the forge's own API (gitea's swagger, "Team": id, name, description,
// organization, includes_all_repositories, permission, units, units_map, can_create_org_repo; "User": id, login, ...;
// repos/search: {ok, data:[Repository]}; Repository.permissions {admin, push, pull}). The live answer is read once the
// tool is delivered (issue 1563 AC2).
