feat(rectification): submit varga-resolution implementation for review

Review-only snapshot for BUG-1115 through BUG-1117; not merge-ready. New opening and append-turn PostgreSQL permission failures remain blocked. Persisted joint replay has zero completed questions; segment ordering remains off by default. The existing offline replay JSON is retained stale and unchanged after a denied overwrite, including its CRLF line endings. Browser/provider validation and final serial gates remain pending. No deployment, role permission changes, or staging/main push.
