SQLite version
The SQLite version is inherited from modernc.org/sqlite — the exact build follows whatever that dependency ships in go.mod. We don’t pin or fork SQLite itself; the only pin we maintain is on the modernc dependency (and its tightly-coupled modernc.org/libc, see Limits).
Compile-time SQLite features (FTS5, JSON1, math functions, R-Tree/geopoly, dbstat, pre-update hook, SESSION, …) are all enabled in the modernc build — see Build tags. To move SQLite versions, bump modernc.org/sqlite (just bump-modernc); go mod tidy carries the matching libc pin.
