Optionaleditable?: booleanWhen true, card surfaces should render an editable variant of the subject (full-bleed editor) rather than a read-only preview. Hosts opt in per-cell — e.g. plugin-board passes editable for in-place editing in grid cells.
Optionalextrinsic?: booleanSet when the card is sized by its container (e.g. a frame on a canvas) rather than its intrinsic content, so the surface can fit its content to the box instead of sizing to it.
OptionalignorePaths?: ReadonlyArray<string>Paths to omit from the card body (caller-defined redundancy; e.g. Kanban hides pivot). Dynamic-schema cards honor this; fixed-shape cards may ignore.
Optionalprojection?: ProjectionModelOptional projection model (set by form/kanban/pipeline consumers that pre-project the subject).
