 Upgrade the `libsqlite3-sys` dependency from `0.35.0` to `0.37.0`. The crate is used with `features = ["bundled"]` for static builds.
 
-A previous manual attempt to upgrade failed on compile, so the agent should investigate compatibility with our current `matrix-sdk-sqlite` dependency and resolve any breaking changes.
+## Version Notes
+
+- Current: `libsqlite3-sys 0.35.0` (pinned transitively by `matrix-sdk 0.16.0` → `matrix-sdk-sqlite` → `rusqlite 0.37.x`)
+- Target: `libsqlite3-sys 0.37.0`
+- Latest upstream rusqlite: `0.39.0`
+- **Blocker**: `matrix-sdk 0.16.0` pins `rusqlite 0.37.x` which pins `libsqlite3-sys 0.35.0`. A clean upgrade requires either waiting for matrix-sdk to bump their rusqlite dep, or upgrading matrix-sdk itself.
+- **Reverted 2026-03-17**: A previous coder vendored the entire rusqlite crate with a fake `0.37.99` version and patched its libsqlite3-sys dep. This was too hacky — reverted to clean `0.35.0`.
 
 ## Acceptance Criteria
 
-- [ ] `libsqlite3-sys` is upgraded to `0.37.0`
+- [ ] `libsqlite3-sys` is upgraded to `0.37.0` via a clean dependency path (no vendored forks)
 - [ ] `cargo build` succeeds
 - [ ] All tests pass
+- [ ] No `[patch.crates-io]` hacks or vendored crates
