Versioned Semantic Workspaces
What is a semantic branch, diff, and merge when schemas, mappings, data, provenance, and reconciliation evolve together?
Question and scope
stable identities, semantic three-way merge, conflict classes, rollback, and historical queries.
Research artifacts
workspace model, version graph, semantic diff, merge rules, and reproducibility examples.
Evidence and evaluation
branch and merge fixtures with schema/data co-versioning.
Claim boundary
every semantic conflict merges automatically.
