 ## R02. Original-object Git overlays retain the caller's PWD

+**Priority:** P2. **Status:** Complete. This addressed the interaction of A02/A12
 with the existing process environment helper and native Git hooks.
 
+**Completion:** Child overlays now start from `Cmd.Environ()` after setting
+`Dir`. Directory-derived `PWD`, explicit overrides/removals, and parent-state
+preservation have process regressions; a native Go pre-push hook verifies public
+publication from another directory. Both new regressions failed before the fix
+and pass afterward. Process, Go-tool, and Git suites passed under `-race`;
+public hook and original-object source/build eligibility regressions passed.
