Development record

The v0.15.1 release review found the brief at .abcd/development/brief/05-internals/01-agents.md:137 out of step with the shipped code. It says: The intent-auditor 'has three roles ... Each role has its own verb ... Only the first ships.' In the code: Two roles ship: the same chapter marks role 2 (`abcd intent consistency`) as '(shipped, itd-48)' at line 162, the binary registers `intent consistency`, and agents/intent-auditor.md declares Role 2 (cross-document). Only role 3 (`intent shape`) is unshipped.
