> **(medium)** Using `userParams.get(name) == null` to fall through to
> positional lookup means an explicitly bound null named parameter is silently
> replaced by whatever is registered under the position key - `containsKey`
> should distinguish "bound to null" from "absent". Related: the new
> `c.getIndex() < params.length` guards at lines 188/195 silently skip binding
> instead of failing, turning a caller bug into an unbound-parameter
> SQLException far from the cause.
