Module diagnostics 

Opt-in diagnostic channel for inspecting how a detection was produced.

The items in this module expose intermediate evidence from the detector pipeline — the dense ChESS response map and the Radon heatmap — rather than the detection result itself. They exist for debugging, parameter tuning, and visualization: rendering a response map as an overlay, checking why a corner was or was not seeded, or sweeping a threshold against a heatmap.

These are not part of the normal detection result contract. The supported way to obtain corners is Detector plus DetectorConfig; a typical consumer never needs this module.

Stability

This channel carries a looser stability promise than Detector and DetectorConfig. The shape of an intermediate response map or heatmap may change as the detector internals evolve, even when the detection result contract does not. Treat anything reachable here as advisory diagnostic data, not a versioned API guarantee.

Structs

DetectorDiagnostics

Detector-bound accessor for the diagnostic outputs in this module.

ResponseMap

Storage for a dense detector response map (one score per pixel). Dense response map in row-major layout.
