PERTAIN_TORootCause

WCC just finds disconnected subgraphs (no modularity optimization). Tension: communities are coarse and don't capture thematic clusters. Degree counting assigns scores by connection count rather than graph centrality. Outcome: landmark promotion is unreliable.

PERTAIN_TOReport

Use Cheeger spectral certificates and modularity lift to gate community visualization

PERTAIN_TOProblem

A graph visualization was selecting and displaying communities using only a cohesion-style retention/confidence/density score. — graph visualization. Outcome: the atlas could show noisy or immature communities.

PERTAIN_TOSolution

Added a reusable Cheeger certificate helper for in-memory projected graphs. — existing community cohesion pass. Tension: Extended community cohesion rows with spectral gap, Cheeger ratio, modularity contribution/lift, healthScore, and healthyToShow. Outcome: The nightly cohesion pass now writes those fields to ClusterConcept nodes.
