Burner Campaign Orchestration

The burner runs as a long steady-state supervisory loop rather than pulsed shots, so orchestration emphasizes continuous supervision over sequencing.

Steady state changes the shape

The burner (Aegis / MetroVolt) is a D-3He tandem-mirror generator targeting steady-state operation, not the pulsed shots of the breeder. Its campaign is a long-running supervisory procedure: establish the plug and throat fields, reach the operating point, then hold it while continuously supervising stability and direct energy conversion. State changes are rare and deliberate rather than a fixed shot sequence.

STANDBY -> PUMPDOWN -> THROAT_FIELD(17 T) -> PLUG_FIELD(26.49 T)
        -> FUELLING(D-3He) -> IGNITION_APPROACH -> STEADY_STATE(hold)
        -> CONTROLLED_SHUTDOWN

Continuous supervision, not sequencing

In STEADY_STATE the dominant activity is supervision: the plug-stability supervisor runs continuously, the envelope checker validates the operating point on every update, and small corrective setpoints flow through the full gating pipeline. The neutron fraction is low at 5.44%, so neutron-driven interlocks are one input among several rather than the dominant hazard as on the breeder.

Housing-specific policy

Aegis (fixed defense installations): availability and predictable, deliberate state changes are weighted heavily.
MetroVolt (data centers): the supervisory loop coordinates output with load, still under the same envelope and rate limits.
Both share one orchestration codebase; only policy parameters and scheduling differ.

Design-and-simulation status

The burner is a design-and-simulation study; there is no built machine and no net-gain claim. Its steady-state orchestration is validated against the digital twin and simulated long-duration runs, exercising the establishment saga, envelope holding, and checkpointing of a procedure that in principle never ends.
