- the provided-crate source identity counts the .rs files of src/ and literal include targets only: hidden entries, target, nested packages (a fuzz folder), stale lockfiles and notes no longer make makepad run refuse to start - the build scripts that embed that identity rerun when srchash.rs changes - a refused save is reported when it is saved (56 ms, was 1 s) - the declaration rollback snapshot covers only the visible crates' entries Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
