algovoi-keystone-autogen

Carry an AlgoVoi keystone decision into an AutoGen conversation. The decision's content-addressed execution_ref rides on a message's metadata under algovoi.keystone.* (never inside an AutoGen reserved field), so anyone reading the conversation recomputes it offline with only JCS (RFC 8785) and SHA-256 and confirms the action is consistent with the decision that authorized it.

from algovoi_keystone_autogen import stamp_message, verify_trace_execution_ref

stamp_message(
    message,
    decision_ref="sha256:2a444c62...", action_type="payment", scope="bilateral",
    outcome="COMMITTED", executed_at_ms=1716460800000,
)
verify_trace_execution_ref(message.metadata)   # True iff execution_ref recomputes

keystone_message_metadata(...) returns the dict if you prefer to merge it yourself. The package never imports AutoGen (it stamps any object with a metadata dict, or a dict message), so there is no version coupling. Apache-2.0.
