See [`REFERENCE-ARCHITECTURE.md`](https://github.com/cmangun/agentic-evidence/blob/main/REFERENCE-ARCHITECTURE.md) for the suite-level architecture.\n\nStandard receipts and trace semantics for **verifiable agent execution**.\n\nThis repo defines:\n- Receipt and trace event schemas\n- Canonicalization rules for deterministic hashing\n- Hash-chaining and signature envelopes\n- Redaction semantics that preserve integrity verification\n- Test vectors for cross-implementation compatibility\n\n## Why this exists\n\nMost agent systems produce logs. Logs are not verification. This specification defines receipts that can be independently validated to confirm:\n1. What the agent did\n2. Under which policy constraints\n3. What artifacts were produced\n4. Whether the record was tampered with\n\n## Core Concepts\n\n- **Trace**: ordered event stream (JSONL) describing agent actions.\n- **Receipt**: cryptographic attestation for an event (hash + prev_hash + signature).\n- **Bundle**: portable directory containing trace + receipts + artifacts + metadata.\n- **Policy Decision**: allow/deny receipt produced by a non-bypassable policy layer.\n\n## Quick Start\n\n- Validate schemas: `./tools/validate_schemas.sh`\n- Review examples: `examples/minimal/`\n- Use vectors to build verifiers: `vectors/v1/`\n\n## Compatibility\n\nDownstream projects should treat this repo as the canonical source of truth for:\n- `schemas/`\n- `spec/`\n- `vectors/`\n\n## Threat Model\n\nSee: `spec/threat-model.md`\n\n## Framework alignment\n\nThis spec implements the **receipts and trace semantics layer** of [ATVC — the Agentic Trust Validation Certification framework](https://enterprise-ai-playbook-demo.vercel.app/). Specifically:\n\n| ATVC Phase | Coverage |\n|---|---|\n| **Phase 02 — Architecture** (steps 26–50) | Receipt schema, canonicalization, hash-chain, signature envelope, redaction model |\n| **Phase 03 — Engineering** (steps 51–75) | Conformance test vectors, threat model, validation tooling |\n\nConformance vectors in `vectors/v1/` are referenceable as ATVC validation artifacts for the Architecture phase-exit contract.\n\n## Suite\n\nThis repo is part of the **Agentic Evidence Suite**:\n- [agentic-receipts](https://github.com/cmangun/agentic-receipts) (standard)\n- [agentic-trace-cli](https://github.com/cmangun/agentic-trace-cli) (tooling)\n- [agentic-artifacts](https://github.com/cmangun/agentic-artifacts) (outputs)\n- [agentic-policy-engine](https://github.com/cmangun/agentic-policy-engine) (governance)\n- [agentic-eval-harness](https://github.com/cmangun/agentic-eval-harness) (scenarios)\n- [agentic-evidence-viewer](https://github.com/cmangun/agentic-evidence-viewer) (review UI)\n\n## License\n\nMIT","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcmangun%2Fagentic-receipts","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcmangun%2Fagentic-receipts","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcmangun%2Fagentic-receipts/lists"}
