@hypit/region-evidence

Frame-exact external spatial evidence. The package relates prepared region observations to one Timeline and resolves normalized boxes inside an explicit program-picture Frame. It performs no detection, identity inference, interpolation or source-to-picture placement discovery.

<import as="region" from="@hypit/region-evidence@1"/>
<region:Evidence id="heads" within={vertical.bounds} timeline={program.timeline}
  recipe={tracking.heads.default}/>

heads.default {
  series: [
    {"id":"GUEST","regions":[[0.12,0.09,0.20,0.26],null]}
  ];
}

Each series has exactly one normalized [x, y, width, height] box or null per Timeline Frame. The resulting RegionEvidence contains resolved SpatialFrame values in the program picture plane. The chosen Frame may be the Canvas bounds, an inset or any other explicit region.

Source-local observations must be projected through the actual visual presentation before they are written as final evidence. That adapter may use the same SpatialMap2D used to fit the source; it belongs with the presentation/evidence workflow rather than in @hypit/spatial.
