Basic Information

The following findings need to be verified. Found during #57

Findings to flag (not fixed — src bugs uncovered):

Statement::bindParametersFromContainer — plain-array params (no errata) build empty bind type string → mysqli_stmt::bind_param(): Argument #1 ($types) must not be empty. Worked around in tests via ParameterContainer + errata. Real bug in execute(array) path.
getTrigger()/getTriggers() throw TypeError: TriggerObject::setActionOrder() wants string, MySQL INFORMATION_SCHEMA.TRIGGERS.ACTION_ORDER returns int. Library bug.
Statement::prepare() InvalidQueryException branch dead under PHP 8.1+ (mysqli throws mysqli_sql_exception, never returns false).
Metadata\Source::loadConstraintDataNames()
