The system of record.
A queryable knowledge graph of every autonomous actor in the estate — and the append-only, cryptographically chained audit of every action taken.
What it is
Chronicle is the single answer to the question every security team must be able to ask: who did what, under whose authority, when, and why. Every Visca product emits to Chronicle, and every event references a Sigil and a Capability Grant. Two views over the same substrate: a graph view of actors, their lineage, their Bundles, their capabilities, and their relationships — and an immutable, chronologically chained log view, queryable by Sigil, by Capability Grant, by resource, by time. Cryptographically tamper-evident: any modification to a past event invalidates the chain forward.
The problem
Today, the information needed to answer accountability questions exists, but it is scattered across framework traces, tool-side logs, identity events, and model-provider logs. None share an identity, a schema, or a chain of authority. Stitching them together to answer a single question is hours of human work — and for security, compliance, and incident response teams, that is the blocker on autonomy adoption.
Capabilities
A typical query
-- In the last quarter, which actors held stripe:refund,
-- who authorized each grant, what was the largest refund issued,
-- and what was the consent trail?
SELECT actor.sigil, grant.principal, action.amount, consent.trail
FROM chronicle.actions action
JOIN chronicle.grants grant ON action.grant = grant.id
JOIN chronicle.actors actor ON grant.sigil = actor.sigil
WHERE grant.capability = 'stripe:refund'
AND action.at >= now() - interval '3 months'
ORDER BY action.amount DESC;Open and commercial
Chronicle is delivered through two surfaces: an open-source reference in Lattice Runtime (MPL 2.0), and a managed, enterprise-grade delivery in Visca Cloud. Features in the open never move behind the paywall.

Across the platform
Cryptographic identity for autonomous actors.
Issues, verifies, and revokes the cryptographic identity every autonomous actor holds — bound to principal, runtime, and lineage from the moment of instantiation.
Zero-trust access for autonomous actors.
Brokers every access from an autonomous actor to a consequential resource — identity-bound, scoped, time-limited, audited. Long-lived credentials disappear.
The autonomic fabric.
Discovery, mTLS, and routing across every autonomous actor and every resource an actor reaches — rooted in Sigil identities, not hardcoded URLs.
Data model as code.
The declarative primitive for your data model. Agents write it as source; humans edit it as a spreadsheet. Plan, apply, drift-detect.
The autonomy economy is shipping
Build, run, and trust autonomous systems on an integrated platform — software, embodied, and hybrid. Open foundation. Enterprise cloud. No license rug-pulls, ever.
