Detailed Description

Supplies diagnostics for an ODBC handle.

Exists so error paths can be driven from a unit test without a database. Production code never installs one: with no source configured, SqlErrorInfo reads diagnostics from the driver as usual. A test installs a source that returns a scripted SqlErrorInfo, which makes the classification and propagation logic reachable without provoking a real driver failure.
