Configuration Corpus Parity Input Corpus Parity, Config Space Coverage	concept	Environment Parity	How closely the set of configurations a pre-production environment exercises resembles the set production actually carries - the parity dimension that decides whether a config-triggered latent bug is found by …
Environment Parity	concept	Environment Parity	How closely a pre-production environment reproduces the properties of production that actually cause failures.
Production Parity Gap	concept	Environment Parity	The enumerated list of ways a pre-production environment differs from production, which is the list of defect classes it cannot catch.
Provenance Parity History Parity, Build-Path Parity	concept	Environment Parity	Similarity between environments in how they were built and changed over time - the parity dimension that decides whether a rehearsal transfers, and the one that manifests and version numbers cannot show.
