AI Decision Governance API
Prime Form Calculus is a governance API that evaluates AI actions against policy rules before execution, verifies authorization, and turns each governed decision into a signed, tamper-evident, and verifiable record.
Prime Form Calculus turns AI decisions into signed, tamper-evident, and verifiable governance records.
Hosted allow decisions include signed governance receipts that downstream services can verify, and the SDK includes an optional enforcement wrapper for protected handlers.
PFC receipts provide portable proof that downstream systems can verify offline. Learn how receipt verification works.
Receipts link together in append-only order so teams can detect broken continuity instead of trusting ad hoc logs.
Stored runtime provenance makes historical decisions replayable against the evaluator version that originally produced them.
Teams can retrieve, verify, and review governed decisions as durable audit records rather than transient application output.

App Store description: PFC Verifier is a simple trust tool for AI decision receipts. Paste or scan a receipt and instantly see whether it is valid, invalid, or warning-level. Built for transparent AI governance, auditability, and cryptographic receipt verification.
PFC Integrations
PFC is the execution-boundary control plane. The ecosystem access layer now includes installable Python packages for teams looking for a PFC Python package, an execution-boundary Python package, or a practical LangChain governance adapter without replacing the hosted runtime.
Explore PFC integrations for developers to install pfc-core and pfc-langchain, copy working snippets, and understand how framework proposals are intercepted before execution.
From Proposal to Proof
PFC governs actions at the execution boundary and proves exactly how an allowed action came to exist.
You can see how decisions become verifiable in the Creative Lineage Demo.

AI audit trail explained shows how traceability and execution evidence fit together.
Proposal → Governance → Execution → Proof
PFC enforces authorization at the moment of action, not just access. This AI security model applies execution-time authorization and runtime policy enforcement as a zero trust execution layer that helps prevent unauthorized actions.
Prime Form Calculus is designed to help organizations govern automated decisions in environments where policy enforcement, auditability, and operational control matter. Teams mapping the problem space can move from AI execution risk into execution control at the execution boundary.
The first step is recognizing that AI execution risk appears when outputs become actions in production.
Every AI decision request is evaluated against defined governance policies before execution.
Each decision remains available as signed evidence in a tamper-evident decision chain, and allow decisions include a verification-ready governance receipt.
If a request violates policy or authorization rules, the action is blocked before it can execute.
Each organization's policies, API keys, and governance records are securely isolated.
Creative Lineage
PFC can explore multiple possible actions without granting any of them authority. It evaluates each candidate under live policy, authority, and state conditions, and only an explicitly bound admissible action receives an execution receipt. The system can also prove exactly which signed exploration artifact that execution came from.
Most systems try to filter outputs. PFC proves how an explored possibility became an allowed action.
