Detailed Description

CVODE-specific triggers that decide when to (re)partition the reaction network engine.

This header provides three concrete Trigger<CVODESolverStrategy::TimestepContext> implementations:

• SimulationTimeTrigger: fires when the simulated time advances by a fixed interval.
• OffDiagonalTrigger: fires when any off-diagonal Jacobian entry exceeds a threshold.
• TimestepCollapseTrigger: fires when the timestep changes sharply relative to a moving average.

It also provides a convenience factory (makeEnginePartitioningTrigger) composing these triggers with logical combinators defined in trigger_logical.h.

See the implementation for details: src/lib/solver/strategies/triggers/engine_partitioning_trigger.cpp
