Development record

The brief at .abcd/development/brief/04-surfaces/README.md:148, .abcd/development/brief/04-surfaces/README.md says: The help-placement table gives the people block's `release` group as `launch` alone, and `embargo` appears in no row of the table (neither a people group nor the agents-and-hosts block). The shipped surface differs: `bin/abcd-darwin-arm64 --help` lists two verbs under Release: `embargo` and `launch`. commands/embargo.md declares `block: people`. The table's placement of every visible verb leaves embargo out. (v0.14.2 release crosscheck, stale-count, raised by opus+sonnet in a31, b00.)
