qortara-protocol
Shared Pydantic models and JSON Schema for the Qortara Governance wire protocol.
This package defines the request/response contract between a Qortara Governance client SDK and its sidecar, plus the evidence and attestation structures emitted by the system. It is the single source of truth for downstream SDKs (qortara-governance-langchain and future framework adapters) and for any compatible sidecar implementation.
What's in here
| Model | Role |
|---|---|
ActionRequest |
The action a client wishes to perform, serialized for policy evaluation |
ActionDecision |
The sidecar's response — allow / deny / require_approval / exempt |
EvidenceRecord |
The durable record of what happened, emitted after execution |
PortableTrustAttestation |
Ed25519-signed credential describing the subject's trust posture |
SidecarHealth |
Sidecar introspection, for liveness probes and diagnostics |
PolicyCacheState |
Pinned-policy-pack state, for audit and cache coherence |
JSON Schema files for each model are distributed in the schema/ directory alongside the Python source. Use the schemas if you are implementing a non-Python client or need language-agnostic validation.
Install
pip install qortara-protocol
Requires Python 3.10+, Pydantic 2.13+, cryptography 46+.
Usage
from qortara_protocol import ActionRequest, ActionDecision
req = ActionRequest(
subject_id="agent-42",
action_kind="tool.invoke",
resource={"type": "Tool", "name": "send_email", "args": {...}},
)
# Serialize and send to the sidecar; deserialize the response:
decision = ActionDecision.model_validate_json(sidecar_response_body)
Stability
Alpha. The protocol is versioned via schema filenames (*-v0.1.json). Breaking changes will bump the schema version and this package's minor version together.
