Slot: Lag Alignment Specifier (lag_alignment_specifier)

Free-form specifier paired with lag_alignment_applied to capture the concrete lag values (e.g. "3" for a 3-day lag, or "0-21" for a distributed lag from 0 to 21 days). Empty when lag_alignment_applied = none.

Tier: optional

Why this slot matters

Knowing that a lag was applied is useless without the concrete value(s); a 3-day lag and a distributed lag over 0-21 days define entirely different exposure windows and cannot be reconstructed after the fact.

In plain terms

This spells out exactly how many days the exposure values were shifted relative to the clinical event — for example 3 days, or a whole range like 0 to 21 days.
