Slot: Privacy Transformation Note (privacy_transformation_note)

Free-text detail of the privacy transformation named in privacy_transformation: the trigger / threshold, determinism, and governance basis. E.g. "reassign to largest hex in same ZIP3 when hex∩ZIP3 population ≤ 20,000; HIPAA expert determination; deterministic".

Tier: recommended

Why this slot matters

The transform name alone does not say what triggered it, at what threshold, or under what governance — two deterministic-jitter records with different thresholds perturb locations differently. Recording the trigger, determinism, and legal basis is what makes the perturbation reproducible and auditable rather than merely acknowledged.

In plain terms

The spelled-out details of the privacy change: what set it off (for example a small local population), the exact cutoff used, whether it always does the same thing, and the legal rule it follows.
