+/**
+ * @file ledgerHistoryAutomat.js
+ * @description Double-buffered chunk list automat (`ledgerHistoryAutomat`) for
+ * append-only ledger transactions and stock journal with multi-filter caching and LRU eviction.
+ *
+ * Upstream Triggers:
+ * - `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()`.
