Media type name: application

Media subtype name: vnd.vnd.svr.receipt+json

Required parameters: N/A

Optional parameters: version: SVR specification version (default "1.0")

Encoding considerations: binary

Conforms to RFC 8259 (The JavaScript Object Notation Data
Interchange Format).

Security considerations: The media type contains a JSON object with an Ed25519 digital
signature. The signature covers the canonical serialization of
the receipt content (excluding timing and presentation fields).
Consumers MUST verify the signature against a known public key
before trusting the receipt content. The receipt does not
contain executable code. JSON parsing SHOULD use a strict
parser that does not evaluate expressions.

Interoperability considerations: The Signed Verification Receipt (SVR) format is defined by
the SVR Specification v1.0, available at:
https://github.com/Jasonleonardvolk/sigma/blob/main/satya/spec/SVR_SPEC_v1.txt

Published specification: SVR Specification v1.0
https://github.com/Jasonleonardvolk/sigma/blob/main/satya/spec/SVR_SPEC_v1.txt

Applications which use this media: AI verification engines, legal technology platforms, compliance
audit systems, financial disclosure analysis tools, healthcare
documentation systems, defense source-chain verification,
scientific integrity checking, autonomous systems safety
verification.


Fragment identifier considerations: NONE
