 The Minimum Supported Rust Version is **1.63.0** (enforced by our CI).
 
+CI uses the committed `Cargo.lock` with `--locked`, including the Rust 1.63 jobs.
+To refresh dependencies, run `./ci/pin-msrv.sh` with Cargo 1.84 or newer and commit
+the generated lockfile. Keep the MSRV checks enabled when changing these pins.
+The Foundation BDK crates in the wallet and examples must use the same revision
+so their update and checkpoint types, including serialization, remain compatible.
