Cooperative Contribution Charter¶

Founding agreement (artifact) — instantiates Shared-Benefit Contribution Governance

A written founding agreement that names the shared benefit, fixes who the contributors are, and states the fair-share rule everyone signs up to — the reference every later contribution and dispute is measured against.

A Cooperative Contribution Charter writes down, before the work begins, the three things a cooperating group keeps arguing about later: what the shared benefit is, who is inside the circle of contributors, and how burden is meant to map to benefit. Its defining move is to be a reference, not an actor — it does no work, pools no money, and punishes no one; it converts implicit, contestable norms into an explicit, ratified agreement that every later contribution, recognition, and dispute can be measured against. The charter's power is legitimacy: because members agreed to it up front, "I never signed up for that" stops being an escape hatch, and the group has a common measuring stick instead of a contest of memories.

Example¶

An open-source library that grew from one maintainer to twenty contributors keeps hitting the same friction: companies land big features and disappear, leaving a handful of volunteers to review everyone's code and answer issues. Before it burns those volunteers out, the project ratifies a contribution charter. It states the shared benefit plainly — a dependable, well-reviewed library the whole ecosystem builds on — defines who counts as a contributor and how someone earns maintainer merge rights (the membership boundary), and sets the fair-share rule: maintainers carry a share of review and triage proportional to what they merge, not just their own features. When a vendor later starts merging heavily but never reviewing, no one has to improvise the norm in the heat of the moment — the charter everyone ratified already says what a fair share looks like, and the conversation starts from there.

How it works¶

The charter's whole job is to turn contestable norms into a legitimate, referenceable agreement:

Name the shared benefit concretely. State the common outcome the group exists to produce, in terms specific enough that anyone can point to it.
Draw the membership boundary. Say who is a contributor, how someone joins, and how they leave — so the circle of obligation is knowable, not assumed.
State the fair-share rule. Make explicit how what you put in is meant to relate to what you get out, whether as a quota, a proportion, or a principle.
Ratify it. Have members actually agree, which is what converts a wish list into a legitimate reference they can be held to.

Tuning parameters¶

Fair-share specificity — a precise quota is clear and checkable but rigid and gameable; a principle ("contribute in proportion to what you draw") flexes to circumstance but is arguable at the edges.
Membership tightness — an open, easy-join boundary grows the commons but dilutes commitment; a gated one builds a committed core but drifts toward an exclusive club.
Ratification bar — unanimous consent maximizes legitimacy but is slow and can be held hostage; majority is faster but leaves dissenters less bound.
Amendment ease — easy amendment keeps the charter alive as circumstances change but weakens it as a stable reference; hard amendment is stable but ossifies.
Scope — a thin charter (benefit + membership + fair share) stays readable and durable; a thick one that also specifies roles, sanctions, and exit overlaps other mechanisms and goes stale faster.

When it helps, and when it misleads¶

Its strength is a legitimate, shared reference: it pre-empts "that was never the deal," shows newcomers exactly what they are joining, and hands every later dispute a common measuring stick instead of a contest of memories. Its failure modes are the dead document nobody reads, and false precision — a rule that looks fair but quietly advantages whoever wrote it. And because no charter can foresee every case, treating it as if it settles everything invites brittle, letter-of-the-law rigidity; every charter is an incomplete contract.^[1] The classic misuse is writing or amending the charter after a conflict to retroactively justify one side, or treating the act of signing as if it were itself a contribution. The discipline is to keep it thin, living, and paired with a real renegotiation path — the charter sets the terms; it does not do the work or settle the hard case alone.

How it implements the components¶

The charter fills the definitional components — the terms the rest of the machinery operates against, not the operating itself:

shared_benefit_definition — it names, concretely, the common outcome the group exists to produce.
contributor_set_and_membership_boundary — it fixes who is a contributor and how membership is entered and left.
burden_benefit_alignment_rule — it states the fair-share principle mapping what each member contributes to what they receive.

It does not enforce that rule — that's Graduated Free-Rider Response — nor pool and allocate resources (Participatory Budget or Resource Pool), nor make ongoing contribution visible (Contribution Board or Dashboard).

Instantiates: Shared-Benefit Contribution Governance — it is the founding reference the whole governance scheme hangs on.
Sibling mechanisms: Graduated Free-Rider Response · Working Group or Pod Structure · Mutual Aid Roster · Reciprocity Check-In · Time Bank or Service Credit System · Collective Threshold Pledge · Contribution Board or Dashboard · Cooperation Retrospective · Participatory Budget or Resource Pool · Peer Commitment Round · Rotating Stewardship Schedule

Notes¶

A charter is a reference, not a contribution: ratifying one is easy and can create a false sense that the cooperation problem is solved, when all that exists so far is an agreement about terms. It earns its keep only when the group actually measures against it — and when it is revisited as reality outgrows it, rather than left to fossilize into a document everyone signed and no one reads.
