This procedure is defined in the server but not documented via ad_proc or proc_doc and may be intended as a private interface.
The procedure is defined as:
proc nsmcp::accessRecordStoreOpen {settings mode} {
# This factory is the only scanner entry point tied to a concrete engine.
# Adapter batches are opaque to the scanner; no handle crosses a slice.
return [::nsmcp::AccessRecordStoreSQLite new -settings $settings -mode $mode]
