No outstanding issues

When a new proposal (issue) is created, the issue is generally assigned to the person who makes the proposal and put in "submitted" status.
Once the team agrees to the general approach and decides to go to validation status, chair moves the issue to "in validation" status and the Secretariat creates a branch. If further discussion is necessary, the issue is moved to "in discussion" status.
Once the team agrees to the final proposal, asignee consolidates the finalized the proposal in the original post, updates the branch, and post a comment saying "branch updated" with mention to Chair and the Secretariat. (Please do not change issue status.)
Chair confirms that the proposal is finalized and the associated branch is updated, and moved the issue to the "validated" status.
