Can C2PA provenance be redacted without lying? This paper says yes, with ZK proofs over hidden image metadata.

C2PA provenance dies the second you need privacy, so redaction matters.

i don't think that's true, since a hard redaction is exactly where a soft proof can keep some provenance value without revealing the sensitive bit, so privacy and evidence don't have to be mutually exclusive.
