Before integrating

Publishes JavaScript with JSDoc, not TypeScript declarations. Inferred signatures are labeled separately.

This reference is generated from the integrity-verified npm archive for this exact version. Signatures describe the public contract; they are not standalone programs. Complete examples are checked separately.

This package ships JavaScript with JSDoc, not .d.ts files. The signatures below are inferred from that published source. An inferred any reflects missing type information in the package.

Import conditions

Use the public entry point above. The package resolves it to these shipped files; do not import its internal files directly.

Condition	Published file
default	`./src/crypto/proof.js`

AgentLineageProof

Agent lineage proof with migration-compatible optional security bindings.

Legacy instances remain parseable, but every verification method rejects them with LegacyInsecureProof.

Signature

declare class AgentLineageProof {
  constructor(fields: Record<string, any>);
  static generate(parentKeypair: any, parentDid: any, childDid: any, derivationPath: any): Promise<AgentLineageProof>;
  static generateBound(parentKeypair: OasKeyPair, binding: { parentDid: string; childDid: string; derivationPath: string; verificationMethod: string; childVerificationMethod: string; childPublicKeyMultibase: string; parentDocumentDigest: string; parentDocumentSequence: number; generation: number; }): Promise<AgentLineageProof>;
  static fromJSON(input: any): AgentLineageProof;
  type: any;
  parentDid: any;
  childDid: any;
  derivationPath: any;
  algorithm: any;
  publicKeyMultibase: any;
  verificationMethod: any;
  proofPurpose: any;
  canonicalization: any;
  childVerificationMethod: any;
  childPublicKeyMultibase: any;
  parentDocumentDigest: any;
  parentDocumentSequence: any;
  generation: any;
  signature: any;
  verify(): Promise<void>;
  verifyWithKey(trustedPublicKey: Uint8Array | string): Promise<void>;
  toJSON(): Record<string, string | number>;
}

Source: @openagentid/oas-vanilla@1.0.2, src/crypto/proof.js:412.

parseLineageProofForMigration

Returns migration diagnostics without establishing authority.

Signature

declare function parseLineageProofForMigration(input: any): Readonly<{ proof: AgentLineageProof; profile: "strict"; authorizes: false; }> | Readonly<{ proof: AgentLineageProof; profile: "legacy"; authorizes: false; diagnosticCode: "LegacyInsecureProof"; }> | Readonly<{ diagnosticCode?: string; proof: AgentLineageProof; profile: "unsupported"; authorizes: false; }>;
