Density is observed.
Desirability comes later.

Explicit cohort + explicit space + explicit sampling policy

Spatial descriptors, not hierarchy judgments

MicroDetailSpatialPointEvidence

Distribution cohorts are explicit

MicroDetailDensityReferenceFrame

Grid resolution is policy

Grid cell density

MicroDetailDensityMap

Local window is explicit

MicroDetailLocalDensityDescriptor

Nearest neighbor is geometry only

Group distribution descriptor

MicroDetailDistributionSet

Attach, do not mutate 15.00 seeds

Zero density and N_A are different

Density is policy-relative

Dense is not noisy by definition

Topic15 ownership chain

Correction routes to geometry/frame/policy owner

CANON → LAB → DATA → IDEAS

Visual laboratory hook

15.02 regression suite

Tests cover point lineage, duplicate conflicts, explicit grouping, multi-role membership, frame/grid validation, row-major cell assignment, zero-vs-N_A semantics, clipped local windows, nearest neighbor, empty groups, deterministic distribution sets and immutable attachments.
