Clicking an on-pane element scrolls to and flashes its assignment row. Off-pane and cross-surface elements stay hover-only. A single owner-qualified registry keyed by {owner, face} backs both data-face surfaces, package and UI, so the same face name under two owners never collides. The pure helpers in app-core.js take all state as arguments and return data. The one stateful adapter, previewSpan, lives in previews.js and emits the escaped markup. os() stays a package-owner wrapper over previewSpan, and a unified locateClick dispatcher replaces the per-surface click branches. Covered by test-locate.mjs and four new browser gates. Full harness green.
