Spectral / Markov Generator

Discrete state stability and the absorbing barrier
A discrete Markov model confirms that correct operator order creates a stable non-absorbing rotating attractor, while wrong order creates a locked-off absorbing state — from which no recovery is possible without physical intervention.

The continuous flow dynamics can be discretized into a Markov chain over five states: OFF, LAMINAR, TRANSITION, VORTEX, and CHAOS. The generator matrix L encodes transition rates between states.

Under correct operator order, the generator L_correct has a positive spectral gap — the smallest nonzero eigenvalue of −L is bounded away from zero. The system returns exponentially fast to the VORTEX state after any perturbation. VORTEX is a stable non-absorbing attractor.

Under wrong operator order, L_wrong drives the system to CHAOS, which functions as an absorbing barrier: once reached, P(CHAOS → VORTEX) = 0. No spontaneous recovery occurs. The only escape is a physical reset — draining the basin and recommissioning.

The spectral gap also determines the recovery timescale after a storm surge temporarily disrupts the vortex. A larger gap means faster recovery. The contact geometry of the correct-order system maximizes this gap.

Engineering consequence
HVEH modules recover automatically from flow disturbances as long as they are in the correct-order state. A module that fails to re-establish vortex rotation within one tidal cycle after flow resumes is flagged for recommissioning, not repair.
