Overview

One resolved route from a table to the scope.

relation is the belongs_to the route leaves through (nil when the plain BFS picked it). Exactly one of the two other members is set:

- `path`         — table names from this table up to a directly-scoped
                 ancestor, compiled into a chain of JOINs.
- `target_query` — the arm target's own (already scoped) extraction
                 query, used when the target carries no scope column
                 and no join path reaches one, but is scoped by other
                 means (referenced_by / reverse_scope / the belongs_to
                 cascade). The arm then probes that query's ids.
