## TEMPLATE_DRAFT: REPLACE BEFORE PUBLISH

## Executive Summary

AgenticCodebase v${VERSION} advances production-readiness with measurable delivery outcomes and explicit operational expectations for integrators.

## Business Impact

This release reduces onboarding friction, improves release-risk visibility, and tightens the execution path from local validation to shared deployment environments.

## Rollout Guidance

Roll out through staging first, verify MCP/server wiring and compatibility checks, then promote to broader environments with release telemetry enabled.

## Source Links
