new progression.adapters project, no engine reference. Stores take a directory path; Godot resolves user:// with GlobalizePath and passes it in, which is what makes them testable at all - originally I'd written this slice off as untestable. version lives in a file envelope, not the snapshot, so the domain only knows the current shape. A newer-build save reports Corrupt with a reason instead of masquerading as "no save" and getting overwritten. atomic write via temp + rename. One file per aggregate: saving a run leaves the profile file byte-identical, asserted. guard rail fixed - it was matching prose in doc comments, now anchored to using-directives plus a project.assets.json check. 63 tests.
