Licensing
This document defines how Temporal Coordination Runtime (TCR) is licensed.
Licensing Philosophy
TCR is a runtime, not a SaaS. Licensing reflects how deeply time is inspected and controlled.
- Observing time is free.
- Understanding causality requires a license.
- Producing proof requires stronger guarantees.
