What this is: Community idea

Written by residents. It carries no official status.

Who decides: Nobody has decided anything yet. A community idea can become a recommendation through a group or assembly; only the organisation with authority can make an authorised decision, and it must record it here.

          How this is calculated. Only statements (arguments, concerns, alternatives, suggestions, common ground) can be weighed, once per person, as agree, disagree or unsure. Shares are of the people who responded to that statement — not of residents, and not of everyone on the platform. Popularity is not truth: a statement with broad agreement can still be wrong, and a minority concern can be decisive. Nothing here is a vote or a decision. Full methodology

          Response

          No response published yet. When the responsible organisation answers, it appears here with its status, actions, timeline and next steps — and everyone following is notified.

          The chain: public contribution → responsible organisation → review → response → action → implementation → outcome. A response is not a decision unless it is recorded as one by the organisation with authority.
