The Magenta Platform is the runtime governance substrate that enforces binary execution gating through an epoch engine, capability enforcement system, independent proof-verification layer, and an append-only, tamper-evident audit chain. It is a default-deny execution control plane for autonomous agents, institutional workflows, and regulated decision systems that need authority enforced before actions run. It is a single-tenant reference implementation, not a hosted production SaaS, and it claims no compliance certification.

  • Epoch engine: append-only, SHA-256 sealed baseline management
  • Capability enforcement: epoch-bound authority grants with delegation ceilings
  • Append-only, tamper-evident audit chain: every governed action logged, every epoch hashed

MAGENTA PLATFORM

Runtime Governance Substrate

The execution control plane. Default-deny enforcement for autonomous agents, institutional workflows, and regulated decision systems.

What Platform Provides

The Magenta Platform provides the foundational governance substrate that all execution must pass through before any action is permitted.

  • Epoch Engine

    Append-only baseline management. Hash-linked history. SHA-256 sealed.

  • Capability Enforcement

    Authority grants, scope limits, delegation ceilings. Epoch-bound permissions.

  • Proof Verification

    Independently verifiable evidence of gate decisions. Replayable with a standalone verifier that trusts no server. Tampering fails verification.

  • Audit Chain

    Append-only, tamper-evident record. Every governed action logged. Every epoch hashed.


Canon v1.1 Extensions

Canon v1.1 adds three first-class primitives enforced by the Platform governance runtime through execution physics.

CAT

Canonical Authority Topology. Machine-verifiable authority with cryptographic binding.

ETDP

Economic Trust & Deployability Proofs. Independently verifiable evidence — not a compliance certification.

Corrigibility

Agents propose, humans authorize. A fully-wired production human-override channel is a roadmap goal.


Platform and the MDK

The MDK is the reference initialization model, not a required public runtime. In the reference model it connects an artifact's structure to the Platform governance runtime by establishing a committed baseline epoch.

Together, in the reference model, they describe how execution eligibility is established: structural conformance via the MDK, governance enforcement via the Platform.
