Codex-style review of session file changes: one card per edit turn (click a file to jump into that turn), a review tab with switchable split/card views (persisted across restarts), sticky headers and turn-scoped syntax-highlighted diffs, a live pill/badge that follows the in-flight turn, 12 fully-wired color settings with light/dark presets that follow the DSH theme live, one-click per-turn revert via a built-in tool (works on DSH Desktop too) that fills the revert instruction into the composer, workspace-relative paths and a resilient multi-stage session-history fallback chain (cold-boot channel attach) for the current DSH session API.
