locations in the original UTF-8 bytes. Displayed locations use one-based lines
and UTF-8 byte columns.
**Show in diagrams** finds representations of a model record in saved diagrams,
process/chain canvases and scenarios. Use the Text toolbar with the caret on a
unique, verified alias in clean accepted sources, or the model tree's context
menu for the chosen record. Choose a destination, then its exact representation.
Lookup runs from an accepted-model snapshot; navigation preserves source drafts,
accepted geometry and history. Pending edits or modal operations must be
finished first. Changed or stale results cannot activate a different target.
Membership follows the actual projection, including visible ports, state action
and internal-transition rows, qualified reuse tiles, and SequenceLink arrows
painted inside caller previews. Repeated callers have distinct destinations
within the same canvas. Hidden preview endpoints and deeper nested links that
the renderer does not draw are excluded; projected adjacency without an actual
relation is not a SequenceLink usage. Preview-arrow focus lies on a visible
line segment outside opaque tiles.
An Allocation projection represents a direct Allocation relation by grouping
only when its visible source performer placement occurs on the visible target
work placement's actual visual-parent chain. Aggregate-only allocation summaries
do not create direct relation usages. The navigation marker can focus a work
header, port owner or state row independently of semantic selection: selecting
an Allocation or state-action relation retains that relation as the model action
target. Camera movement preserves a valid marker; changing the selected record,
document, accepted revision or represented context retires it. Navigation does
not alter allocation ownership or the meaning of Delete.
Changing a graphical UUID must atomically update map keys and every reference.
Alias changes preserve UUID identity. Deletion must account for owned elements,
incident relationships, ordered occurrences, and diagram placements without
