The life of a case Diagram

When a draft is submitted

Typing keeps a private draft on this device. Leaving the case, Cmd+Enter or Ctrl+Enter, Escape, or 30 seconds without an edit submits it. Hiding the page also submits it.
A submitted draft is a proposal. Version 1 exists only after acceptance; later accepted content changes add versions. A blank draft or unchanged content adds no version.

Who accepts a proposal

Loose accepts ordinary edits by rule. Standard asks a person to accept or refuse an agent’s edit; a person’s ordinary edit is accepted by rule. Strict asks a person for every ordinary edit, with a reason.
The proposal waits in the queue where a person is required. Refusing it records the answer and leaves the current version alone.

An older version is a base, not an error

Mainworthy merges compatible changes automatically. Conflicting changes wait for a choice by the author if a person, or a human admin. An agent author may withdraw the proposal and try again on the current version.
A manual merge creates a fresh proposal under the original author’s identity. The policy still applies. More recent overlapping edits can cause another conflict. The device keeps text that the confirmed merge has not recorded.

History and archive

Restoring old content is a proposal too. Acceptance adds a new version containing that content; the old versions stay. If the content already matches, no new version is needed.
Archiving and bringing a case back also go through a proposal and acceptance under the policy. They change whether the case is active, without adding a content version.
