Development record

The v0.15.1 release review found the brief at .abcd/development/brief/02-constraints/04-naming.md:49-51 out of step with the shipped code. It says: The namespace root refuses any positional that is not a record id, so `status` is not a registered command. In the code: `abcd status` is a registered top-level verb (root --help, Records group: 'List everyone's announcements, reservations and releases being cut'), with commands/status.md and .abcd/development/brief/04-surfaces/39-status.md.
