A202: the Verifiable Agreement Protocol for Agent-Led Commerce

Status: Informative in full.

A202 is verifiable commerce for agent-to-agent or agent-led transactions: an open specification of commercial authority, negotiation state, and verifiable conformance for transactions between independent organisations, including transactions conducted on their behalf by software agents.

It defines typed objects for delegated commercial authority, a state machine for the transaction and for each bilateral session inside it, rules for what may be disclosed to whom, and an executable conformance suite that turns each of those into a check an implementation either passes or fails.

The full statement of purpose, scope, and non-goals is in CHARTER.md.

Created and developed by A. A. Musse. See MAINTAINERS.md.

Status

Released, pre-1.0.

v0.1.0 is the first tagged release of the set: a tag, a digest for every schema file, the conformance manifest, and release notes, published together. See RELEASES.md and CHANGELOG.md. Before 1.0 a MINOR increment may break compatibility, and any break carries migration notes.
The name is A202, spoken "A two-oh-two", and in full A202, the Verifiable Agreement Protocol for Agent-Led Commerce. The long form is a descriptor and not an expansion: the letters do not stand for it. The 202 is HTTP 202 Accepted, which A202-0017 makes the status an accepted submission returns, because acceptance is the primitive the rest of the specification is built on. The A202- reason-code prefix, the A202-NNNN proposal identifiers, and the a202-commercial/0.1 specification version string all follow from the name.
A202™ is a trademark of Plural Worlds. Permitted use of the name is stated in TRADEMARK.md.
Schema $id values resolve under https://schemas.a202.org. Fixture hosts use reserved .invalid names, because test data must never resolve.

`conformance/`	Fixtures, manifest, normative runner, and the conformance grade definitions

Each specification document carries a status header stating which of its sections are normative and which are informative.

Running the conformance suite

The runner validates every fixture named in the manifest against the schemas, then applies the invariants that JSON Schema cannot express. Schema validity is not conformance, which is the reason the runner exists.

It needs jsonschema>=4.18. If that is not on the system interpreter, a virtual environment is enough:

python3 -m venv .venv && .venv/bin/pip install "jsonschema>=4.18"

Run it from the repository root:

python3 conformance/run-conformance.py --verbose

The expected result is every fixture passing and none failing, with the totals the manifest carries: the manifest is the single source for the count, and the runner prints it on every run. The runner also asserts that each negative fixture is refused for the reason code the manifest declares for it, wherever the normative layer raises codes at all. Run it before and after any schema change.

Every negative fixture is minimal: removing the single offending element must leave a document that validates cleanly. A negative fixture that fails for an incidental reason tests nothing, so verify that when adding one.

The suite does not depend on anyone remembering to run it. It runs, together with the reference implementation tests and the MCP server tests, on every pull request and on every push to the default branch, under .github/workflows/checks.yml. GOVERNANCE.md section 3.4 requires the suite to pass for any change to schemas, fixtures, the manifest, or the runner, and that workflow is what turns the requirement into a gate.

Where to start reading

CHARTER.md for what this is and what it deliberately is not.
schemas/canonical-commercial-model-v0.1.md for the object model, the envelope, and the invariants schema validation cannot express.
negotiation/pilot-transaction-state-machine-v0.1.md for what moves state and what does not.
conformance/manifest-v0.1.json for the fixtures that decide whether an implementation agrees with either of the above.
