I’m just assuming that the dataintegrity column of the historian’s data table corresponds to the data quality codes everywhere else in Ignition.  
The only code I can’t find in the manual is 405. Anybody know what it is for?

Looks like it’s very similar to 404, NOT\_FOUND.

`
	/**
	 * Similar to NOT_FOUND, but that quality is used in the browse tree and in other places to mean
	 * "the tag you want doesn't exist". This quality is used to indicate a reference to a tag is not valid.
	 **/
	REFERENCE_NOT_FOUND(405, 6);`
