# Three requestless `@connect` directives, each reading data that only exists
# when a transport is configured. Every field below should trigger
# `RequestlessSelectionUsesRequestData`:
#
# - `Query.greeting`   — implicit `$root` (the response body).
# - `Query.code`       — bare `$status` (Details collapses to `$status`).
# - `Query.trace`      — nested `$response.headers.trace` (Details lists the
#                        full subtree; three source ranges are recorded).
