AI Decision Governance API
Prime Form Calculus is a governance API that evaluates configured authority, policy requirements, and supplied execution context before governed actions proceed through a protected execution path, and can produce signed, tamper-evident decision evidence for supported governed decisions.
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 cryptographic evidence of the recorded governance decision that downstream systems can verify offline with the required trusted key material. 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.

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 evaluates actions at the execution boundary and preserves verifiable evidence linking a governed decision to its recorded lineage.
You can see how decisions become verifiable in the Creative Lineage Demo.

Proposal → Governance → Execution → Proof
PFC evaluates authorization at the protected execution boundary, not just at initial access. When downstream systems require valid PFC authorization, this model adds execution-time policy enforcement that can reject actions that do not satisfy configured governance requirements.
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 governed request violates configured policy, authority, or safety rules, PFC returns a deny outcome. Protected downstream systems must honor that outcome and require valid authorization before execution.
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 cryptographically link the governed decision to the signed exploration artifact from which it was derived.
Most systems try to filter outputs. PFC preserves verifiable lineage from explored possibilities to the recorded governed decision.
