graduated disclosure
a disclosure of an ACDC that does not reveal its entire content in the initial interaction with the recipient and, instead, partially or selectively reveals only the information contained within the ACDC necessary to further a transaction with the recipient. A Graduated disclosure may involve multiple steps where more information is progressively revealed as the recipient satisfies the conditions set by the discloser. Compact disclosure, Partial disclosure, Selective disclosure, and Full disclosure are all Graduated disclosure mechanisms.

Lifting confidentiality step by step: Selectively disclosing more data as time and/or necessity progresses, offering backward verifiability of earlier issued cryptographic proofs.
You proof your insurance policy without disclosing details before enjoying extreme sports. Only when something goes wrong, e.g., 1 in 100, do you disclose the data. This way confidentiality is kept in 99% of the cases.
Disclosure performed by a presentation exchange that has cross-variant (see compact variant) Issuer commitment verifiability as an essential property. It supports graduated disclosure by the Disclosee of any or all variants wether it be full, compact, metadata, partial, selective, bulk issued, or contractually protected.
Paraphrased by @henkvancann based on source
The SAID of a given variant is useful even when it is not the SAID of the variant the Issuer signed because during graduated disclosure the Discloser MAY choose to sign that given variant to fulfil a given step in an IPEX graduated disclosure transaction.
The disclosure performed by a presentation exchange MAY be graduated and MAY be contractually protected.
