F.13:1 - Intent & applicability
Intent. Preserve historical reading when source-local expressions, Concept-Set row labels, or names of governed values and their descriptions change:
- new names clarify without erasing what earlier texts meant;
- aliases remain local to Contexts;
- a changed meaning is recovered under its defining rule and receives an explicit revision, replacement, split, merge or retirement disposition; a rename cannot supply that decision.
Applicability. Use this when changing a source-local expression, an external label or address of a SchemeSenseCell, a Concept-Set row label, or the name of a governed value or description. First say which of these is changing; their identity rules differ.
