Frequently asked
Straight answers to real questions.
Is the engine really fully open source?
Yes. The CoherenceEngine, SettlingService, ContradictionDetector, and ActionValidationService are all Apache 2.0. Fork it, self-host it, build on it. No "open core tricks" inside the core engine — the limits are at the platform layer only.
What counts as a "claim"?
A claim is any assertion pushed to POST /claims or extracted from POST /observations. Think of it as one fact about one entity at one point in time. Claims are lightweight — typical agent sessions generate hundreds to thousands, not millions.
Can I start self-hosted and migrate to Cloud later?
Yes. The Cloud API is a drop-in replacement for your self-hosted endpoint. Change one line in your InvariantClient config — same SDK, same methods, same response shapes. No data migration required.
