conftest test-DB defaults matched the project's own running postgres
(roboco/roboco @ localhost:15432, the docker-compose roboco-postgres
service with CREATEDB) instead of the OS user on localhost:5432 which has
no such role — every db_session test failed with InvalidPasswordError
instead of running.
Once the DB connection worked, the self-heal origination DB test went RED
with MAIN_PM_NO_CODE: the self-heal root was task_type=CODE owned by
main_pm, the combo the main_pm_cannot_own_code guard rejects. The Main PM
coordinates the fix (delegates the code work to a cell dev); it has no
code verb. Retyped CODE→PLANNING and rewrote description/AC to
coordination-level.
