The version 2.4 Content Credentials specification defines a Content Credential as the preferred nontechnical term for a C2PA manifest. The manifest can contain assertions, a claim, a signature, and bindings to the asset. The trust model is concerned with the signer's identity; the consumer uses that identity and other signals to decide whether the assertions are true.

What validation means
Validation can establish whether the manifest is well formed, whether signatures and bindings validate, whether the credential is associated with the asset, and whether declared history or assertions remain intact under the specification's rules.
Validation does not independently observe the depicted world. A correctly signed assertion can be incomplete, mistaken, or misleading. Trust in a signer and factual verification remain separate decisions.
The C2PA principles make that boundary explicit. The standard should verify that assertions are associated with the asset, correctly formed, and free from tampering. It should not judge whether the provenance is good or bad.
Missing and recovered credentials
C2PA manifests may be embedded or external. Metadata can be removed intentionally or accidentally. The FAQ describes soft bindings and cloud retrieval as recovery mechanisms, but their availability depends on the asset and implementation.
Absence therefore does not prove that media is synthetic or deceptive. Presence does not prove the depicted event occurred.
Human identity
The current C2PA FAQ states that the core specification does not attribute content to individuals or organizations. Identity work can be provided through separate recommendations, credentials, or implementations. A reader must inspect who or what signed the claim and what trust basis the interface exposes.
NIST relationship
NIST AI 100-4 separates provenance tracking from content-based synthetic detection. It treats interpretation and evaluation as central issues and warns against relying on a single intervention.
Publication boundary
Use the terms manifest, assertion, signer, signature, binding, validation, trust, ingredient, and provenance carefully.
Do not call a credential a truth certificate. Do not say it is permanent, universal, impossible to remove, or proof of a verified human author.
