Module pending_queue 

Universal delta encoding for SSZ lists that behave as FIFO queues.

This module handles both pure FIFO queues (e.g., consolidations, withdrawals) and logically-FIFO queues with rare reordering (e.g., deposits).

It guarantees correctness by strictly validating item boundaries during overlap detection and ensuring the remaining base queue matches the target prefix exactly.

Functions

apply_queue

Applies a universal queue delta in place.

diff_queue

Computes the delta between two serialized queue lists.
