understand-current_delay

CALL NUMBER: deep_spinlock.current_delay DEFINITION: The computed wait interval for the current retry iteration; derived from base_delay multiplied by backoff_multiplier raised to the iteration count, then capped by delay_ceiling.

Invoke this skill to understand current_delay down to its primitives. The RELATIVE ROOT below is the least-fixed-point closure of everything it bundles from — the full import cone, grouped by the lib each prim comes from. Projected from a prover-typed KB (MAP/SWI-Prolog consistency gate): every reference below resolves.

THE RELATIVE ROOT (the import cone, by lib)

from deep_spinlock

• backoff_multiplier (d1): Scaling factor (commonly 2.0) that multiplies the current delay on each failed acquisition attempt to produce the next delay interval.
• base_delay (d1): Initial wait time in nanoseconds or microseconds before the first lock acquisition retry; the starting point of the exponential schedule.
• delay_ceiling (d1): Upper bound cap on the computed delay; prevents unbounded growth of wait times when contention persists across many iterations.
