+ * In-memory `SurrealClientView` used by unit tests. Records every call.
+ *
+ * Lives under `src/` (not `tests/`) so coverage configs that exclude
+ * `tests/**` still account for usage — but it is intentionally never
+ * referenced by production exports (the root barrel never re-exports it),
+ * so consumers do not see it.

+ * The adapter rewrites named placeholders into positional `$pN` and passes

+ * keyed by `pN` so unit tests can inspect bound values predictably.
