Architecture before autonomy.
UMBRA is the governed operational plane. PENUMBRA is the human-facing interface. Together they create a bounded place where humans, AI, applications, and authorized entities can interact without confusing capability with authority.
UMBRA
Model-, agent-, device-, manufacturer-, and vendor-agnostic control architecture for identity, authority, intent, policy, execution, telemetry, verification, provenance, escalation, revocation, and receipts.
PENUMBRA
The human-facing layer that makes state, evidence, uncertainty, permissions, review, exceptions, and stop-the-line controls legible to the accountable person.
Capability does not equal permission.
A federation layer for independent organizations and architectures to communicate through common protocols for identity, authority, intent, constraints, capability exposure, execution, verification, and receipts without requiring a shared database, AI model, or software stack.
