 ### Fixes
 
+- Agents/sessions: preserve terminal lifecycle state when final run metadata persists from a stale in-memory snapshot, preventing `main` sessions from staying stuck as running after completed or timed-out turns.
 - Status: show the `openai-codex` OAuth profile for `openai/gpt-*` sessions running through the native Codex runtime instead of reporting auth as unknown. (#76197) Thanks @mbelinky.
 - Plugins/externalization: keep diagnostics ClawHub packages and persisted bundled-plugin relocation on npm-first install metadata for launch, and omit Discord from the core package now that its external package is published. Thanks @vincentkoc.
 - Plugins/Codex: allow the official npm Codex plugin to install without the unsafe-install override, keep `/codex` command ownership, and cover the real npm Docker live path through managed `.openclaw/npm` dependencies plus uninstall failure proof.
