import { NoydbStore } from '@noy-db/hub/to';

/**
 * **@noy-db/to-memory** — in-memory store for NOYDB (testing and development).
 *
 * Backed by nested `Map` objects: `vault → collection → id → envelope`.
 * Data is lost when the process exits — this store is intentionally
 * non-persistent.
 *
 * ## When to use
 *
 * - **Unit tests** — fast, zero I/O, works in any environment.
 * - **In-memory caching layer** — pair with `routeStore` to keep a hot
 *   copy of frequently-read collections in memory while persisting to
 *   a durable backend.
 * - **REPL / prototyping** — explore the NOYDB API without setting up
 *   a backend.
 *
 * ## Capabilities
 *
 * | Capability | Value |
 * |---|---|
 * | `casAtomic` | `true` — Map operations are synchronous and inherently atomic |
 * | `txAtomic` | `true` — multi-record `tx()` applies every op in a single synchronous burst |
 * | `listVaults` | ✓ — iterates outer Map keys |
 * | `listPage` | ✓ — cursor-based pagination over sorted id list |
 * | `ping` | ✓ — always returns `true` |
