algovoi-a2a-journey

Compute a content-addressed journey_ref over an A2A multi-agent task run — the ordered hops plus the outcome — and detect tampering. Open tier, Apache-2.0. Python and TypeScript byte-for-byte identical, and byte-compatible with the AlgoVoi commercial journey tier.

Keystone Enabled — discovered by the AlgoVoi keystone control panel. Verify it yourself: pip install algovoi-keystone-control && keystone-verify algovoi-a2a-journey → PASS.

journey_ref = "sha256:" + SHA-256(JCS({
    "delegations": [],          # always empty in the open tier (moat boundary)
    "hops":        [execution_ref, ...],
    "journey_outcome": "COMPLETE" | "PARTIAL" | "ABORTED",
}))

from algovoi_a2a_journey import journey_ref, tamper_detected

ref = journey_ref(
    hops=["sha256:" + "a" * 64, "sha256:" + "b" * 64],   # one execution_ref per agent hop
    outcome="COMPLETE",
)

# anyone can recompute and detect tampering with no AlgoVoi service:
tamper_detected(ref, ["sha256:" + "a" * 64, "sha256:" + "b" * 64], "COMPLETE")  # -> False

What the open tier does and does not do

The open tier lets you hash a task run, not prove it. delegations is always [] — proving the chain's properties is the commercial Orchestrator. Upgrading requires no migration: the open journey_ref is byte-identical to the commercial one called with delegations=[].

Keystone control panel

This package registers a journey_a2a source under the algovoi.keystone.steps entry-point group, so the AlgoVoi keystone control panel auto-detects it as a journey-stage source.
