Feature: Small accountability circles for weekly contributions

[sajeetharan]

Problem

Individual missions provide direction, but developers may still lack lightweight social accountability to finish a meaningful contribution.

Proposed solution

Offer opt-in circles of 3-5 developers with compatible goals. Members choose one weekly contribution intention and share bounded progress states.

Acceptance criteria

• Joining, goals, and visibility are explicit and reversible.
• Matching uses declared language, time budget, and goal; never private behavior inference.
• Progress states are supportive and do not expose failure streaks or rank members.
• Circles have inactivity expiry, reporting, blocking, and safe exit controls.
• No direct contact information is exposed.
• Track weekly intention, useful check-ins, verified completion, and four-week retention.

Success metric

Four-week retained contributors completing meaningful actions, not message volume.
