Chapter 31 — Release Management Governance¶

31.1 Purpose¶

This chapter establishes the constitutional governance framework for Release Management within the Engineering Intelligence Platform.

Release Management governs the controlled publication, delivery, and lifecycle management of approved Engineering Baselines.

Its objective is to ensure that every released engineering artefact is complete, approved, reproducible, traceable, and configuration-controlled.

31.2 Definition¶

A Release is a formally approved Engineering Baseline that has successfully completed the required engineering governance activities and is authorized for operational use.

Release Management governs engineering delivery and publication.

It does not modify constitutional governance.

31.3 Authority¶

Release Management Governance derives its authority from:

Engineering Constitution
        │
        ▼
Approved Governance System
        │
        ▼
Engineering Baselines
        │
        ▼
Release Management (ARP)

Release authority remains subordinate to the Engineering Constitution.

31.4 Objectives¶

Release Management Governance shall ensure:

controlled engineering publication;
engineering completeness;
release reproducibility;
release traceability;
release integrity;
controlled operational deployment.

31.5 Release Scope¶

Release Management applies to all approved Engineering Baselines, including:

Engineering Specifications (SP)
Interface Contracts (IC)
Architecture Decision Records (ADR)
Verification Assets (AVP)
Configuration Records (ACM)
Source Code
Firmware
Hardware Documentation
Software Deliverables
Engineering Documentation
Engineering Release Packages

31.6 Release Prerequisites¶

A Release Baseline shall not be established unless all of the following conditions are satisfied:

applicable Engineering Specifications are approved;
required Interface Contracts are completed;
relevant ADRs are approved;
Verification and Validation activities are completed;
Configuration Management records are complete;
required approvals have been obtained.

Incomplete Engineering Baselines shall not be released.

31.7 Release Lifecycle¶

Each Release shall progress through the following lifecycle:

Planned
   │
   ▼
Prepared
   │
   ▼
Reviewed
   │
   ▼
Approved
   │
   ▼
Released
   │
   ▼
Maintained
   │
   ▼
Retired

Every lifecycle transition shall be recorded under Configuration Control.

31.8 Release Manifest¶

Every Release shall include a Release Manifest.

The Release Manifest shall identify:

Release Identifier
Version
Release Date
Configuration Identifier
Included Engineering Baselines
Approval Authority
Release Notes

The Release Manifest constitutes the authoritative description of the Release Baseline.

31.9 Release Traceability¶

Each Release shall maintain traceability to:

Engineering Constitution
Governance Baseline
Engineering Specifications
Interface Contracts
Architecture Decision Records
Verification Assets
Configuration Records

Release traceability shall support audit, maintenance, and engineering reproducibility.

31.10 Release Integrity¶

Released Engineering Baselines shall be immutable.

Any engineering modification following release shall require:

controlled Engineering Change;
updated Configuration Records;
new Release Baseline.

Released artefacts shall not be modified in place.

31.11 Release Compliance¶

Every Release shall comply with:

Engineering Constitution Rev.1
Approved Governance System
Engineering Baselines
Verification Requirements
Configuration Management Procedures

Release approval shall be evidence-based.

31.12 Constitutional Boundary¶

Release Management governs engineering publication.

It shall not redefine:

governance authority;
governance responsibilities;
governance relationships;
governance boundaries;
constitutional lifecycle.

Any constitutional modification shall require Architecture Change Control (ACC).

31.13 Chapter Summary¶

This chapter establishes Release Management Governance as the constitutional framework governing engineering publication and delivery.

It confirms that:

every Release Baseline is configuration-controlled;
Release Manifests are mandatory;
engineering releases are reproducible and auditable;
released artefacts remain immutable;
engineering publication occurs entirely within the approved Governance System while constitutional governance remains stable.
