Resolution coercion

hierarchy

Forcing all inputs to a single target resolution (e.g. always coercing to r8) before comparison discards the finer detail of higher-resolution sources and introduces spurious precision on coarser ones.

Detection

Pipeline hardcodes a resolution constant rather than deriving target resolution from source precision or use case.

Mitigation

Choose target resolution from the coarsest reliable input, not an arbitrary default
Document precision loss/gain per coercion step

Affected conversions

Admin polygons → H3 (weighted crosswalk) weighted
Cell system → cell system approximate
