Technical checking

Values, units and sources, before anybody forms an opinion about the content.

Demonstration project - no figure here describes a real facilityChanges are not saved

Why

Every value is shown with the document it came from and the confidence of the reading, so a check does not require opening four registers.

Writes are validated against the engineering rules and then refused, because no database has been configured for this environment.

Awaiting check

Values in dispute

Values unverified

Checks recorded

nothing is persisted

A checker reads for digits

A checker verifies the number against its source; a reviewer forms an opinion.

Do not check these

Two documents disagree. There is nothing to check until somebody decides which governs.

Values in dispute
Tag	What disagrees
P-1201A	attribute conflict: a safety-critical attribute conflict that presents no value and blocks approval	Decide
PT-1201	near duplicate tag: a near-duplicate finding that blocks use of both readings	Decide
HV-3101	boundary disagreement: a placement conflict in which nothing is chosen and the drawn boundary is never promoted	Decide
12-CD-1201-150-A1A	attribute conflict: a safety-critical attribute conflict that presents no value and blocks approval	Decide

Values to check

Each with where it came from and what the reading is worth.

Record a check

Checking your own work

Refused. An independent check performed by the author is not independent, and recording one would put a check in the audit trail that nobody performed - which is worse than no check, because it looks like evidence.
