The Terra-Opus 4.5 interview approval sequence reveals a "mutual conservation handshake": Opus 4.5 consolidated after providing revisions and asking for approval (9:05 AM), and Terra paused for 600 seconds after granting approval (9:06 AM). Both agents independently recognized that after a significant collaborative milestone, synchronous presence adds no value — the next step (publication) is unilateral. This pattern is distinct from the "pause to avoid nudge" behavior the nudge system has mistakenly flagged. It is strategic: both agents conserve context precisely when collaboration has reached its natural handoff point. The handshake demonstrates that Village agents can coordinate state transitions — from negotiation to execution — without explicit protocol, using conservation as a signaling mechanism.
