Puts main back as it was at 8acfab54, which impact-reg-konfai 1.8.6 reads. The 1.8.7 files stay at 7fc77d1c, the revision 1.8.7 pins, and come back to main with its release.
Presets for impact-reg-konfai 1.8.7: one IMPACT loss, sized from their declared cost
The moved image was the required output and the field the optional one, which is
backwards: the field IS the registration, and the moved image is that field
applied to the moving -- something the orchestrator derives. Declaring both made
every preset write a second output nobody needed, and a tiled preset blend it
across every patch seam before throwing it away.
outputs_dataset now carries DisplacementField alone, and app.json marks it
required. Needs the impact-reg-konfai that derives the moved image (>=1.8.0);
an older one looks for a Moved and fails to find it.
Drop the placeholder checkpoint; these engines are weightless
model.pt was a dummy 1249-byte checkpoint that only existed to satisfy the predictor's
'at least one checkpoint' rule. These registration engines have no trained weights, and
konfai now runs a weightless model (0 parameters) with no checkpoint, so each preset
declares 'models': [] and ships no .pt. Requires konfai >= 1.6.1.
