What shipped: opt-in AER-1 receipt emitters in all 8 framework packages (zambo-vercel-ai 0.1.4, zambo-ai-sdk 0.1.5 on npm; crewai-zambo 0.1.4, openai-agents-zambo 0.1.4, pydanticai-zambo 0.1.4, zambo-smolagents 0.1.3, zambo-llamaindex 0.1.3, zambo-haystack 0.1.3 on PyPI). Zero dependencies beyond stdlib. The emitters mint receipts locally following the AER-1 spec.  The interop result that matters: the JavaScript emitter and the Python emitter produce byte-identical canonical bytes, verified across 3 test cases including Unicode with surrogate-pair escaping. A receipt minted by any Python package verifies against one minted by any JS package and vice versa. That's genuine cross-language interop, not parallel implementations.  Why this matters for the standard: a spec with one implementation is a product. Every framework that can emit conformant receipts is another independent implementation path. The conformance kit is the arbiter: https://zambo.dev/aer1/conformance/  Spec: https://datatracker.ietf.org/doc/draft-zambo-aer1/ (draft-zambo-aer1-02, Brennan Zambo)  If you're implementing agent tooling, the kit will tell you in seconds whether your receipts conform. Run it.",
