DoltLite: A SQLite fork with Git-style version control, built with 2k agent PRs

DoltLite, a beta-ready fork of SQLite version 0.50.0, replaces SQLite’s B-tree layer with a content-addressed Prolly Tree backed by a single-file chunk store, enabling full Git-style version control—including branches, merges, diffs, rebases, and remote push/pull. The storage format has stabilized after 12 changes, and the engine passes 100% of sqllogictest (5.8 M queries) and 99.46% of SQLite’s TCL acceptance suite, with divergences documented.
