`disable_threshold_subtraction`

runtime.subtraction.disable_threshold_subtraction

Disable local threshold subtraction while leaving the original integrand unchanged.

Type: boolean
Required: no
Default: false
Allowed values: Any value accepted by the declared type

`esurface_existence_threshold`

runtime.subtraction.esurface_existence_threshold

Dimensionless tolerance used to compare the energy-squared E-surface invariant margin against esurface_existence_threshold * E_cm^2 at runtime.

Type: number
Required: no
Default: 1e-7
Allowed values: Any value accepted by the declared type

`radial_root_residual_tolerance`

runtime.subtraction.radial_root_residual_tolerance

Multiplier of epsilon(T) * E_cm used as the direct residual limit for threshold-counterterm radial roots at numerical precision T. A residual-limited higher-precision root may instead be accepted against the corresponding lower-precision limit after satisfying the cross-precision consistency checks.

Type: number
Required: no
Default: 64.0
Allowed values: Any value accepted by the declared type
