 ## Current
 
-### `feat/frontend-command-palette-decision`
+### `feat/frontend-xss-hardening`
 
 Status: in_progress
 
 DoD:
-- the `⌘K` affordance in the shell either works end-to-end or is removed everywhere
-- no dead command-palette trigger remains in desktop navigation
-- EN and RU copy stay aligned for the chosen outcome
-- the chosen outcome is verified in the UI smoke path
+- API-derived data is not inserted into `innerHTML` without escaping
+- shared DOM-safe helpers are introduced for frontend rendering paths that still need markup
+- known unsafe rendering paths from `__REVIEW_FRONT.md` are removed or hardened
+- the current UI behavior remains intact after the hardening pass
+- targeted frontend smoke checks cover the touched pages
 
 ## Next
 
-- `feat/frontend-xss-hardening`
+- `feat/frontend-shell-unification`
 
 ## Backlog
