- registry rows for the prefixes this landing uses, claimed before their
first commit as the file requires: `db2-ephemeral` (databasev2 2 task 6a),
`db2-4b` (part B re-brainstorm), `db2-5` and `db2-14` (story docs),
`agents` (the persona roster), `status` (cross-track board/graph sweeps)
- `db2-7` and `lang-18` registered after the fact — both already have
commits on `dev` (`b31bd40`, `6b4b960`) and had no row
