A sampled command delay reads newly written input too early.

Case contract

A nonempty queue stores pending oldest-first delayed commands; return [output,new_queue] after one tick. Its length is the exact integer sample delay.

Why this case matters

An offline discrete controller model isolates this state or arithmetic fault; it makes no physical plant or safety claim.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
single delay	`[2, [2]]`	`[0, [2]]`	Failed
