# Sprint 223 Plan: Parity Metrics and Reporting Closure

## Goal
Make parity-block behavior visible in matrix summary so unresolved divergence and blocked parity are separable.

## Steps
- Step 2154: Add `ab_consistency_blocked_count` aggregate metric.
- Step 2155: Keep unresolved divergence metric (`ab_prod_divergence_count`) as hard signal.
- Step 2156: Re-run hard suites and confirm divergence target is zero.
- Step 2157: Document partial-vs-closed interpretation in tracker docs.
- Step 2158: Add `Sprint223IntegrationSummary.h`.
