wasmagent-protocol 0.1.4

Canonical JSON Schemas for the WasmAgent Agent Evidence Protocol (AEP) and compliance contracts. Single source of truth across the WasmAgent org.

wasmagent-protocol

Canonical source of truth for every cross-repository contract in the WasmAgent org. One public schema → one canonical source.

WasmAgent is open infrastructure for provable AI agents. Proving an agent ran correctly requires that every repository — the runtime, the gateway, the evidence pipelines, the audit product — speak the same evidence and compliance vocabulary. wasmagent-protocol is where that vocabulary is defined, versioned, and published, so no repository has to keep its own copy.

This repository holds specifications only. It contains no business logic, no runtime, and no product code — only JSON Schemas, conformance fixtures, and thin loader packages that expose the schemas to JavaScript and Python consumers.

Why this repository exists

The Agent Evidence Protocol (AEP) and the compliance schemas were originally authored inside wasmagent-js and independently copied into trace-pipeline. By the time this repository was extracted, those copies had drifted: five shared schemas differed (one had a copy-paste title bug, and the same logical schema carried two conflicting $id URLs). Drift in a shared contract silently breaks cross-repo evidence validation — exactly the failure mode WasmAgent exists to prevent.

Per the org repository boundary policy: one public schema has exactly one canonical source. That source is here.

What's in scope

Only contracts that genuinely cross a repository boundary:

Schema	Version	Consumers
aep-record	aep/v0.2	wasmagent-js, wasmagent-proxy, trace-pipeline, wasmagent-train-replay, open-agent-audit
constraint-ir	compliance/v1	wasmagent-js, trace-pipeline
constraint-violation	compliance/v1	wasmagent-js, trace-pipeline
repair-trace	compliance/v1	wasmagent-js, trace-pipeline
task-spec	compliance/v1	wasmagent-js, trace-pipeline
compliance-eval-record	compliance-eval-record/v1	wasmagent-js, trace-pipeline
rollout-wire	rollout-wire/v1	wasmagent-js, trace-pipeline

The machine-readable registry is schemas/index.json.

Out of scope: schemas owned by a single repository (e.g. trace-pipeline's *-training-record output formats, open-agent-audit's audit-run). A schema belongs here only when two or more repositories must agree on it.

Consuming the schemas

Downstream repositories must not copy schema JSON. Depend on the published package instead.

JavaScript / TypeScript

npm install @wasmagent/protocol

import { schemas, getSchema } from "@wasmagent/protocol";

const aep = getSchema("aep-record"); // parsed JSON Schema object

Python

pip install wasmagent-protocol

from wasmagent_protocol import get_schema, schema_path

aep = get_schema("aep-record")        # parsed dict
path = schema_path("aep-record")      # pathlib.Path to the .json file

Versioning & stability

• Each schema carries a version string (see the registry).
• Additive changes (new optional field) → minor package bump.
• Breaking changes (removed/renamed field, tightened required) → major package bump and a new version value, announced in the org release ledger before merge.
• Every schema has at least one valid and one invalid conformance fixture under tests/fixtures/. CI rejects any schema without both.

See docs/CONTRACT-CHANGE-PROCESS.md for the full change workflow and docs/GOVERNANCE.md for maintainer and exit-condition policy.

Development

# validate every schema is well-formed and every fixture conforms
python3 -m pip install jsonschema
python3 tests/conformance.py
