How each point of a parameter sweep (Exploration) obtains its initial state. Determines whether the sweep points are independent (and therefore parallelisable) or whether the trajectory follows a solution branch as the swept parameter is changed quasi-statically. The latter is forward-time-integration branch following — distinct from numerical continuation of equilibria (the Continuation class), which tracks branches with a Newton corrector rather than by simulation.

Default. Independent of each OTHER, which is not the same as each cold-starting: where the experiment declares a transient, the settle is integrated once and every point opens from the state it reached, so what is shared between points is a settled state rather than a running trajectory. That is sound while the swept parameter does not change the approach, and unsound wherever the sweep crosses a bifurcation, since a point then inherits an attractor it would not have reached on its own. A settle per point would make the name literal and is not what the emitter does today; read this as the guarantee it gives rather than the one the word suggests.'from_previous:text: from_previousdescription: Each point is seeded from the final state of the preceding point, so the trajectory follows the solution branch as the swept parameter changes quasi-statically. Forces sequential, order-dependent execution (emitted as a scan, not a vmap). Used to reach a working point by slowly ramping a parameter (e.g. global coupling) and, with sweep_direction, to expose hysteresis / multistability.
