pub const ALL: &[&str];Expand description
Every fixed route above, for clients that want to enumerate the surface (and for the round-trip test below).
ADMIN_TASK_CANCEL, V1_STREAM, V1_STREAM_POLL and
SLOTS_ID are deliberately absent: they are templates, and a
caller iterating this list to probe paths would get a 404 for a
literal {task_id}.
