# Sprint 78 Plan: Enterprise Change Management and Rollout Controls

## Context

Large organizations need staged rollouts, approval chains, and rollback guarantees.
Sprint 78 adds enterprise-grade rollout management for transpilation adoption.

---

## Goals

1. Support staged rollout policies by team/system criticality
2. Require configurable approval chains for high-risk migrations
3. Provide fast rollback pathways and impact analysis
4. Add adoption dashboards and rollout health scoring

---

## Steps

### Step 1009: Rollout stage model (`pilot`, `canary`, `broad`, `default`) (12 tests)
### Step 1010: Approval chain policy engine (10 tests)
### Step 1011: Rollout blast-radius estimator (10 tests)
### Step 1012: Fast rollback orchestration contract (10 tests)
### Step 1013: Rollout health scoring model (10 tests)
### Step 1014: Adoption telemetry integration (8 tests)
### Step 1015: `whetstone_plan_rollout_stage` MCP tool (8 tests)
### Step 1016: `whetstone_execute_rollout_or_rollback` MCP tool (8 tests)
### Step 1017: Enterprise rollout report template (8 tests)
### Step 1018: Sprint 78 integration summary + regression (8 tests)

## Rollout Rule

- High-criticality systems cannot bypass staged rollout and approval requirements.
