An authenticated record or scope user could read records on any table reachable through a graph edge or REFERENCES TO back-reference, regardless of that table's PERMISSIONS FOR select clause.

Traversing SELECT * FROM source->edge->target returned full documents from target even when target was defined as PERMISSIONS FOR select NONE. The same bypass extended through multi-hop chains, so any table reachable by a sequence of edges from a readable starting point was exposed.

The root cause: GraphEdgeScan and ReferenceScan fetched records straight from storage without routing them through Document::pluck select, so the target table's permission expression was never consulted.

An authenticated record or scope user can read records on any table reachable through a chain of graph edges or back-references from a table they have select on, regardless of the target's PERMISSIONS FOR select clause. Confidentiality-only and bounded to the caller's current database — namespace and database isolation are unaffected.

A new per-batch permission cache (exec::permission::CachedTableSelect) resolves each target table's SELECT permission once and filters yielded values through check permission for value, matching the regular SELECT code path.
