Uncertainty calculation status reference

Evaluation status	Meaning
`not_started`	No current calculated revision exists.
`in_progress`	Required point-and-stage evidence is incomplete.
`completed`	Every required point and stage passed completion checks.
`submitted`	The exact revision was frozen with event submission.
`voided`	The evidence is retained but is no longer current.

a fixed revision separately records calculated, submitted, superseded, or voided, plus whether the change was a calculation, recalculation, submission, supersession, or voiding action.

The uncertainty response reports the evaluation status, fixed point results, all information/warning/blocking findings, and active or withdrawn warning acknowledgements. An active acknowledgement records a reason, authorising membership, timestamp, and optimistic version. Withdrawal retains the original record and adds a withdrawal reason, actor, and timestamp.

Saved point results expose combined and expanded uncertainty, effective degrees of freedom, coverage mode and factor, display scale, stage, unit context, calculation actor and time, budget revision, point identifiers, and integrity hashes.

Each point also retains its component results: input value, distribution, resolved divisor, sensitivity coefficient, standard uncertainty and contribution, degrees of freedom, Type A statistics, notes, and frozen source provenance. Recorded Type A observations retain their original decimal strings, unit, actor, and timestamp. The website displays applicable decimal values to three places without changing stored precision.
