A full three-outcome handover protocol exists, but the claim step needs tengu_cobalt_plinth_thistle, which falls back off.

What

When two live sessions of the same conversation are both set to reply to artifact comments, the old behaviour was a warning that every comment would get answered twice. This build adds a real handover protocol with wording for all three outcomes: one session took over, one yielded, or they are still doubling up. The step that actually makes a takeover stick is behind tengu_cobalt_plinth_thistle, which falls back to off.

Details
  • New exported operations request a takeover, hand a claimed artifact back, and announce that a taken-over artifact stopped.
  • The takeover request is issued at the conflict site, but the claim it depends on is only computed when the gate reads true.
  • There is a second early return inside the takeover routine that reports a disabled state; what drives that check is not identifiable from the surrounding code.
  • The gate name is new in this build. Without server configuration, users still see the old double-reply warning.
