/**
 * Engine-version cache invalidation (ADR-0015).
 *
 * The catalog + shard-fragment caches must invalidate when the graph
 * engine itself changes version, so a customer who upgrades opensip-tools
 * never replays a stale catalog built by the old engine. The mechanism is
 * `stampEngineVersion`, folded into the `cacheKey` at every engine-side
 * cacheKey computation — these tests pin the format and the end-to-end
 * contract that a differently-stamped catalog is rejected.
