Typed Contracts and Privacy

Context#

Event payloads and use-case inputs carry no type or schema while trusted payloads claim the fields are fit to act on, and pseudonymize sits as an erasure position although pseudonymized data stays personal data.

Decision#

Use-case inputs and integration-event payload fields carry type (text, integer, decimal, money, boolean, date, date-time, duration, email, choice, id with of) and required; an integration event may name dataschema; money values are { amount, currency }. pseudonymize keeps the class personal, with its basis; anonymize is added; each data class and retention row states purpose; period is an ISO 8601 duration; the retention schedule claims only the time limits of a record of processing.

Evidence with Confidence#

research/lower-layers-practice holds the outside review and the measured counts over the largest consumer behind D31 and D33, high confidence.
