Platform overview¶

Limen architecture

One platform. A small set of engines. Configuration — not code — defines each line of business.

Engines¶

Runtime machinery. Each engine maps to a business component in the codebase.

Parties, roles, hierarchies — one graph for every person and organisation.

Versioned contracts and components — hydrated JSON documents, bi-temporal truth.

Lifecycle, milestones, escalations — time is continuous, not batch.

Append-only money — every movement is an immutable ledger entry.

DMN rules and decision trails — actuaries own the logic, not developers.

CDC-fed read models — reporting never competes with the write path.

Templates, products, behaviour bindings, ledger charts, channels — risk is just data.
