SupportPolicy

core.SupportPolicy()

How to treat a transferred coordinate that falls outside alignment support.

A coordinate transferred to another timeline is out-of-support when the entering coordinate lies outside the transferring WarpMap’s source-anchor hull, or when the produced coordinate would fall outside the target timeline’s [0, length] span. This policy decides what happens to such a timeline when a cross-timeline stamp is assembled.

Attributes

Name Type Description
omit Drop the out-of-support timeline from the stamp entirely. This is the default: a coordinate below the first alignment anchor or beyond the last one has no defined position, so the timeline simply does not appear.
clamp Clamp the entering coordinate to the nearest hull boundary before warping (yielding that boundary anchor’s target), then clip the result to [0, length]. The timeline stays present.
extrapolate Keep the linear extrapolation beyond the hull, then clip the result to [0, length]. The timeline stays present.

No policy ever emits a negative coordinate or one exceeding the target timeline’s length.
