What still counts as evidence?
10–16 October 2026. A record can remain true even when it no longer answers the question now being asked. Two developments in Solway explore that distinction.
What can we still count as done?
The extended When the work changes now starts with work already completed. Adding a seal requirement does not erase an installation or its old inspection. But that inspection cannot stand in for the newly required seal test.
Refining the work breakdown does not automatically mean reinstalling the work either: the question is whether existing evidence covers the new claims. Compare four changes to the brief and see which records survive, which claims they still support, and what remains to do.
What does this measurement justify?
A new essay separates a valid record, relevant evidence, a numerical comparison and acceptance.
Against a 3 mm limit, 4.7 mm and 0.0047 m give the same exceedance. Selecting a revised 5 mm criterion changes the assessment without changing the measurement. A well-formed record can still concern the wrong ring, configuration or property. And a favourable comparison does not grant acceptance: human authorisation remains a separate, unestablished step.
The example makes those distinctions visible and proposes different next review work for each kind of gap.
These are small, fictional cases. Ordinary tables and separately authored planning models reach the same decisions. The contribution is making the scope of evidence inspectable; an advantage from using an ontology remains unproven.
The launch-week issue was expanded on 10 October to cover the whole week. Its initial version gave that day’s work too much weight.
