SURFACE · 01 / PCE · OFF-CHAIN

Policy Compilation Engine.

The authoring surface of the judgment core. The PCE compiles public regulatory corpora and a fund's private mandate into a typed, versioned, source-pinned policy bundle: machine-checkable rules the OMA enforces before execution. Each compile emits a policyCommit hash, the first link of the binding chain.

§ 01 / Architecture

From prose to policyCommit.

Regulation and mandate go in as documents; what comes out is a signed bundle of typed rules a machine can enforce and an auditor can trace back to the exact clause. The typed DSL is the human-facing front end; a policy-as-code engine is the evaluation backend.

§ 02 / Guarantees

Constrained where it must be. Deterministic everywhere else.

GUARANTEE · 01

Glass-Box Extraction

AI operates in exactly one place: reading source text into a typed schema under constrained generation. Everything after extraction is deterministic: compiled, versioned, replayable.

GUARANTEE · 02

Counsel in the Loop

Every uncertain clause routes to counsel before it enters a bundle. Each confirmation, correction, or rejection is recorded as a labelled extraction trace; these traces are the first entries in the mandate's record.

GUARANTEE · 03

Source-Pinned Provenance

Every predicate is verified programmatically, not by another model, against schema invariants and source-text overlap, and carries span-level provenance back to the clause and the reviewer.

§ 03 / The Binding Chain

The first link.

The policyCommit is pinned on the institution’s OMA at onboarding and rebuilt on every mandate amendment. From then on, every downstream surface points back to it: the Validator’s decisionId, the AIA receipt, the STN match ticket, and the settlement evidence.

Jurisdiction rulepacks make the same rail enforce the correct rulebook per participant: an EU module first (MiCA, MiFID II product governance, AIFMD / UCITS depositary evidence), with Singapore and UAE following the launch footprint.

KEY PROPERTY

The rule that was authored is provably the rule that executes. Same bundle, same intent, same verdict, forever.

§ 06 / Access Testing

Join the waitlist for access testing.

Access is rolling out to a scoped cohort of regulated institutions through structured, milestone-gated pilots. Drop your details and we'll coordinate briefings, mandate intake, and pilot onboarding as your category opens.
