- docs/plans/20260525-adr-0035-sql-ddl-4f.md — ALTER TABLE ALTER COLUMN
TYPE plan (/runda'd; forks resolved). Advanced lossy = ForceConversion
(reuse do_change_column_type; existing transformed_lossy note); the
internal-__rdbms_* guard folds into do_change_column_type both surfaces
(user-confirmed); int->serial is ALLOWED (ADR-0018 §8), only non-int
->serial / blob / date<->datetime are static-refused.
- docs/handoff/20260525-handoff-39.md — 4d/4e shipped; 4f is next
(plan ready).
