+= Governance Model
+:toc: preamble
+
+This document describes the governance model for this repository.
+
+== Overview
+
+This repository follows a **Sole Maintainer Governance Model**:
+
+* Single maintainer (@hyperpolymath) has full authority over the project
+* All contributions are welcome and reviewed by the maintainer
+* Decisions are made transparently through GitHub issues and discussions
+* The project adheres to the hyperpolymath estate policies where applicable
+
+== Core Principles
+
+[cols="1,2"]
+|===
+| Principle | Description
+
+| **Benevolent Dictatorship** | Maintainer has final decision authority but seeks community input
+
+| **Meritocracy** | Contributions are judged on technical merit, not contributor identity
+
+| **Transparency** | All significant decisions are documented publicly
+
+| **Consensus-Seeking** | Maintainer prefers consensus but will decide when necessary
+
+| **Open Contribution** | Anyone can contribute via fork and pull request
+
+|===

+
+== Contribution Lifecycle
+
+[cols="1,2"]

+
+In case of disagreements:
+

+. Provide technical justification for positions
+. Maintainer mediates and makes final decision
+. Decision is documented and can be revisited later
+
+== Project Policies
+
+This repository adheres to hyperpolymath estate-wide policies:
+
+* **License**: MPL-2.0 for code, CC-BY-SA-4.0 for prose (per standards/LICENCE-POLICY.adoc)
+* **Code of Conduct**: Follows hyperpolymath CODE_OF_CONDUCT.md
+* **Security**: Follows hyperpolymath SECURITY.md

+
+== Repository-Specific Conventions
+
+[cols="1,2"]
+|===
+| Convention | Description
+
+| **Signing** | All commits must be signed (SSH or GPG)
+
+| **SPDX Headers** | All source files must have SPDX license identifiers
+
+| **Contractiles** | Mustfile, Trustfile, Intendfile, Adjustfile in root
+
+| **Machine Readable** | META.a2ml in .machine_readable/6a2/
+
+| **CI/CD** | GitHub Actions workflows in .github/workflows/
+
+|===
+
+== Governance Evolution
+
+As the project grows, this governance model may evolve:
+
+* **Adding Co-Maintainers**: When contribution volume warrants it
+* **Forming a Team**: For complex multi-maintainer projects
+* **Adopting TPCF**: For large, multi-repository projects (see rhodium-standard-repositories)
+
+Changes to this document require the same process as Significant Changes above.
