Read the route from state in the navigated effect instead of the closed-over match, and build the href base from cf/public-uri instead of location.pathname, via the new pure mirrored-href helper.
Drop the legacy path-param fallback from match->context-params and remove the legacy hash routes (viewer-legacy, workspace-legacy, dashboard-legacy-*) with their redirect components; old URLs now resolve to not-found. render-sprite is kept.
Update the link-preview subsystem doc and extend router tests (subpath base, query clearing, state-as-source).
