/**
 * Catalog versioning and adoption stamps — sensor-map.md §18.3.
 *
 * The AWN catalog grows in versioned steps. A configuration carries two
 * stamps that make its exposure history durable:
 *
 *   - `catalogBaseline`: the catalog version the installation was BORN
 *     at (first created, or converted from legacy). Written once.
 *   - `catalogAdopted`: the newest catalog version whose definitions
 *     are VISIBLE to this config. Advanced only by explicit adoption.
 *
 * Default exposure derives from the baseline by arithmetic: a
 * definition with `sinceCatalogVersion <= baseline` uses its own
 * default; one that arrived later (`baseline < since <= adopted`)
 * defaults to disabled. No per-row bookkeeping, no inventory
 * dependence — offline and never-seen stations resolve identically.
 *
 * Both stamps absent is the DEFINED legacy state: (1, 1), the v1
 * baseline every config in the field has today. Any other invalid
 * combination fails closed (§18.3): the caller enters the safe-mode
 * protective posture rather than capping or resetting, because
 * changing definition visibility out from under an existing accessory
 * was measured to unregister it (PR #65 review round 2).
