Spherical feature API
=====================

The Stable ``panorai-spherical-features/v1`` core orchestrates OpenCV feature
algorithms over PanorAi's canonical gnomonic geometry. Direct spherical DoG
detection, multiscale routing, and virtual-rig/PyCOLMAP export are explicitly
Experimental extensions. The resolution-selection report is also Experimental
and never resizes caller data implicitly. Detector-only spherical DoG,
coarse-to-fine proposals, tangent patches, and tangent OpenCV descriptors are
Experimental composition surfaces. The typed image-pair, feature-pair,
matching and bearing-conversion stages used by ``SphericalRelativePose`` are
also Experimental; their default configuration delegates to the frozen
relative-pose feature profile. See
:doc:`../guides/how-to/spherical_features` for the workflow and integration rules.
