Why: the frontend fix branch carries the preview key unification, orphan-tab adoption, conversation restore, and missing-artifact toast; the Dev gitlink records the tested head ahead of the Frontend PR merge. Evidence: vitest 85/85; fresh-profile browser replay in the task card. Impact: modules/frontend gitlink 84b73ab -> 475fd3a only. Refs: Frontend PR #49; task card feature/empty-state-preview-fix.
