1// Generated by scripts/regen-ceremony-profiles.py. Do not edit.
2// The source of truth is solidity/contracts/ceremony/profiles.json.

4//! The single source of truth for the ceremony profiles. Solidity, Rust and
5//! TypeScript constants are generated from this file by
6//! scripts/regen-ceremony-profiles.py. The Platform Verifiers are hand
7//! written and READ these constants; only the values live here.
8//!
9//! THESE STRINGS ARE OURS, NOT THE SPECIFICATION'S. ceremony-common fixes no
10//! literal of its own: platform-ceremonies REQ-PLAT-01 fixes the profile
11//! NAMES, and every byte below is the profile author's choice. So this is a
12//! cross-implementation agreement, and it is agreed here rather than four
13//! times over.
14//!
15//! Four components must produce the same bytes: this repository's verifiers,
16//! the browser that notarizes three of the four sessions, the deployment that
17//! notarizes the fourth, and the notary that signs what they observed. A
18//! disagreement is silent -- a Consumer dispatching on one string and a
19//! verifier registered under another simply never meet, and a request line a
20//! prover composes one byte differently is an attestation rejected with no
21//! error that says why.
22//!
23//! Changing a value here changes what a deployed verifier accepts. That is a
24//! new ceremonyVersion, not an edit.
