Detailed Description

Per-atom marker spec for the inversion-free path.

One entry per range-table atom (indexed by relid-1). When valid, the planner wraps that atom's provenance token in annotate(prov, inversion_free_key(root_col, sec_col, factor)): a per-input order key built from the tuple's root- and secondary-class column values and its factor (SAFE_CERT_GUARD_FACTOR for the shared self-join guard, else a per-factor id).
