 ## R08: Reuse the existing repository-path semantics for record storage — P2
 
+**Completed:** R04's shared resolver reuses the established Git root and
+metadata-path normalization. Added regressions passed for repository roots and
+separate metadata directories ending in whitespace, default/relative read-write
+agreement, and rejection of absolute unignored worktree stores. Existing ordinary
+and linked-worktree recording tests also passed.

 **Relevant code:** `internal/publish/record.go:112`, especially line 117;
 `internal/publish/attempts.go:74`, especially line 82; the existing
 `internal/git/source.go:39` and `source.go:50` repository-root helpers.
