Engineering data reconciliation

Values the project's documents disagree about, side by side with no answer chosen.

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

Why

Each conflict is read from the project's documents and their evidence. Nothing here is resolved by preferring the higher-confidence reading.

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

Nothing has been decided

Values presented

A conflict presents none

A safety-critical conflict presents no value

EDS does not choose the higher-confidence reading, the more recent document or the more complete record. Where two documents disagree about a design pressure, neither figure is shown as the value: a number nobody can stand behind must not reach a deliverable, and a greyed-out alternative underneath a confident-looking answer is how it would.

Why nothing is chosen for you

A reconciler that picks the higher-confidence value is not resolving a conflict, it is hiding one. Confidence measures how well a reading was made, not whether the document it came from is the right one. The datasheet may be read perfectly and still be the superseded figure.

What this blocks

While a conflict is open, the attribute cannot be verified, nothing may cite it as a value, and any deliverable that depends on it cannot be approved. It can still be drafted: the gap appears in the draft as a gap.
