 * Result of comparing an indexed graph's schema version against the running

 * - `ok` — same major, same minor. Patch differences are deliberately treated
 *   as `ok`: patch bumps are reserved for backward- and forward-compatible
 *   changes that never alter graph bytes or invariants.
 * - `major-drift` — major versions differ; the graph must be re-indexed.
 * - `minor-drift` — the indexed graph is an OLDER minor than the binary; it may
 *   be missing fields/invariants the newer binary expects (backward gap).
 * - `forward-incompat` — the indexed graph is a NEWER minor than the binary; an
 *   older binary cannot assume it understands fields/invariants the newer
 *   schema introduced (forward gap).
