Turning point: 18 reframes the wish’s purpose. Instead of a tool for singular desire, she demands that the artifact respect continuity — not restoration to a prior map, but a consent-based weave honoring lives formed in its wake. The wish offers a single clause: undo the seam, returning each timeline to its prior state, or let the new weave stand, acknowledging the emergent truths. 18 chooses a third path informed by the chorus: entangle the artifact with herself so changes cannot be imposed again without mutual assent. The seam heals, not by erasure, but by establishing a covenant: wishes may cross only with the consent of those most altered.
