# Sprint 221 Plan: SLO/Rollout Constraint Enforcement

## Goal
Require SLO and rollout-choreography constraints to be declared for constrained categories.

## Steps
- Step 2144: Enforce SLO presence for performance-budgeted category.
- Step 2145: Enforce rollout policy fields for rollout-choreography category.
- Step 2146: Emit deterministic blocker reasons for missing SLO/rollout contracts.
- Step 2147: Add closure analyzer outputs to benchmark report set.
- Step 2148: Add `Sprint221IntegrationSummary.h`.
