Documentation

Issue, verify, and attach receipts in minimal code. Covers @peac/protocol, @peac/crypto, and middleware.

Express middleware setup for auto-issuing receipts on API responses.

Attach evidence to MCP tool responses via _meta fields.

Carry receipts through Agent-to-Agent Protocol metadata.

Offline verification with a public key: signature, claims, expiry, and kernel constraints.

Combine multiple receipts into a single portable evidence bundle.

Full specification: record structure, claims, kinds, types, extensions, and conformance requirements.

JWS structure, JOSE header, claims layout, and encoding for interaction-record+jwt.

PeacEvidenceCarrier type, CarrierAdapter pattern, and transport size limits.

Multi-receipt bundle format for audit, dispute review, and archival.

Normative protocol behavior: issuance, verification, error handling, and kernel constraints.

Index of all agent protocol, payment rail, framework, and AI integrations.

Model Context Protocol evidence mapping via @peac/mappings-mcp.

Agent-to-Agent Protocol evidence in TaskStatus, Message, and Artifact metadata.

Auto-issue receipts on Express.js API responses with @peac/middleware-express.

HTTP 402 payment evidence with dual-header read and upstream artifact separation.

All Layer 4 adapters: payment rails, agent protocols, content signals, inference.

Verify receipts, run conformance tests, author policies, and bundle evidence from the terminal.

5-tool MCP server for verify, inspect, decode, issue, and bundle operations in Claude Desktop or Cursor.

Three-level conformance suite: basic (structure + signature), standard (+ claims), full (+ constraints + policy).

Paste a compact JWS and verify it in the browser. No server round-trip.

13 error categories with machine-readable codes, HTTP status mappings, and recovery hints.

Runnable examples: hello-world, x402 payment, MCP tool call, A2A gateway, content signals, and more.

Package reference for the 6-layer architecture: kernel, schema, crypto, protocol, adapters, and applications.

Release history, changelogs, and npm publication status.

Public API surface for @peac/protocol, @peac/crypto, and @peac/schema.

Security model: SSRF prevention, JOSE hardening, no ambient key discovery, fail-closed defaults.

Vulnerability reporting process and responsible disclosure.

Protocol governance model, decision process, and contributor roles.

Protocol research: trust models, agent economy analysis, and standards landscape.
