= Contribution Constitution

== Principles

Contribution authority, intellectual-property permission, and provenance attestation are distinct questions. Passing one does not answer the others. The estate MUST publish contribution routes, review authority, expected evidence, appeal routes, and the perimeter in which a contribution may operate.

Open contribution MUST not be undermined by undisclosed founder-only authorship checks. Restricted paths MAY require named maintainers, stronger review, or verified provenance when the rule is public, proportionate, challengeable, and compatible with the repository's licence.

== Tri-Perimeter model

Perimeter 1 — Core:: Highest-impact work; explicit maintainership and review authority.
Perimeter 2 — Trusted contributors:: Broader change authority earned through recorded, reviewable criteria.
Perimeter 3 — Community sandbox:: Low-risk experimentation without an implication of adoption or production authority.

Movement between perimeters MUST use published criteria and permit challenge. A perimeter describes contribution authority, not ownership of a contributor's identity or ideas.

Contributor-agreement material derived from legal concepts MUST remain labelled *Draft for Legal Review* until competent human review and adoption. It is not legal advice or an executed agreement.
