Interaction surfaces

Distinct surfaces for distinct responsibilities

Hadalian provides a set of stateful interaction surfaces, each designed for a specific responsibility in the lifecycle of business evidence.

Hadalian is one system with one operational record. These products are not modules or add-ons. They are the surfaces through which different participants interact with the same underlying truth.

Each surface enforces what can—and cannot—happen at that stage, so collaboration, coordination, and reliance never blur together.

How products are organized

Products are organized by intent. Control surfaces manage readiness and continuity. Preparation surfaces support collaboration. Reliance surfaces support decision-making.

These surfaces are state-dependent, not interchangeable.

Preparation surfaces

Collaborative environments used to resolve open questions and finalize materials before publication.

What this page does—and does not do

This page catalogs the interaction surfaces available within Hadalian.

It does not describe the evidence lifecycle, explain failure patterns, or prescribe role-specific workflows. Those are covered elsewhere.
