  "violated_contract": "A control that owns a tap must remain the hit-test target for its own bounds, and a tap that cannot complete must surface a failure. An ancestor installed for an orthogonal concern — wrapping SelectionArea, a full-width jump-to-latest overlay, or a last-message min-height spacer — must not absorb those hits or shove the control under another surface. A lookup miss must not return silently.",
  "canonical_prevention": "Keep text selection on markdown only so citation GestureDetectors are not SelectionArea descendants; size overlay chrome to the visible chip and pad the list so it does not cover sources; drop last-message min-height spacers that bury citations; resolve a cited conversation from the local map then fetch by id, and show a snackbar when the fetch returns null.",
