Start with the public docs for platform posture, runtime boundaries, and product vocabulary.

See how the shared runtime, approvals, and ontology surfaces fit together.

Read the high-level platform explanation before diving into module-by-module details.

Use a working session when you want to map your current GTM stack into psi*.

Read the short product and workflow summaries before we get into implementation detail.

See how apps, flows, approvals, and operator handoffs work together.

Use the shared vocabulary page if you want the product model without the codebase detail.
