 /**
  * @file globalHistoryAutomat.js
- * @description Virtualized grid automat (`globalHistoryGridAutomat`) for
- * infinite-scrolling global audit/change history via `react-virtual-aggridautomat`.
+ * @description Double-buffered chunk list automat (`globalHistoryAutomat`) for
+ * global system and change history logs with multi-filter caching and LRU eviction.
  *
  * Upstream Triggers:
- * - `authAutomat`: Subscribes to auth state changes — calls `reload()` when
- *   status reaches `'authed'` with a `selectedCompanyId`.
- * - AG Grid: Triggers `fetchRows()` on viewport scroll, sort, or filter changes.
+ * - `authAutomat`: Subscribes to auth state changes — resets on `'anon'` or when
+ *   `selectedCompanyId` changes.
+ * - Consumer UI: Calls `getItems()`, `requireChunk(start, end)`, `filter(search)`,
+ *   `addSeekMonth()`, `addSeekYear()`, `resetNegativeSeek()`.
