duplicate property
Duplicate is how many members this tenant already held, byte for byte. The idempotency key is the assertion's CONTENT digest — kind, subject, at, seen, disposition, source, evidence, the asserting identity and confidence, folded in length-prefixed — so a webhook redelivering one chargeback is a duplicate and costs nothing, while an assertion differing in ANY of those fields is a DIFFERENT assertion and is recorded beside the first. Nothing was written and nothing was overwritten; it is an outcome, never an error. The asserting identity is in the digest, so the same claim filed by a second credential is two assertions and not a redelivery.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
int? duplicate;
