Live & Local Schema Change: Challenge Problems
summary
Paper claims schema change in live programming and local-first software is the same core problem and offers concrete challenge scenarios rather than full solutions. Examples include extract entity (denormalize to normalized migration plus GUI refactors), divergent structured docs (itemized list to tabular with missing organizer cells), runtime model edits for state machines (deleted current state, type changes) and operational failures like shotgun migration that loop and bloat CRDT history.
