# Forms, data views and data exchange Collect structured input, present records, and plan governed import/export flows using shared models and explicit host ports. Source snapshot: bcc79fcc27c4d801c2119bef81ddcce7b4e86498 ## Choose lifecycle and UI separately FormsRuntime owns management, immutable publication, submission, consent, deterministic navigation, idempotency and document validation. ModuleForms keeps reusable builder, respondent, results and administration behavior. A product host supplies authenticated creator authority, storage, delivery providers, public routing, branding and feature flags. This split helps when embedding a form in an existing product: reuse the lifecycle and selected UI without assuming the package owns your tenant identity or deployment.

A document requiring a disabled milestone is rejected at publication. Verification, AI follow-up, distributed request defense, secrets and outbox delivery are optional host ports until the selected publication policy requires them. Responses remain bound to immutable revisions. When adapting an example, inspect the enabled milestone, required ports, locale fallback and response-session scope together; a working authoring screen alone does not show that a particular published document can accept valid responses.

Its preview and reconciliation surfaces allow a caller to inspect differences before choosing an effectful delivery path. Governed projection contracts carry sharing, consent, residency, retention and revocation responsibilities. Recovery dispatches deliberately contain narrower, receiver-specific references than central queue records. Keep source values and scheduler internals out of an unrelated product’s recovery message.

For import/export, trace decode, schema mapping, validation and preview. Record where trusted actor scope and the selected schema enter that path.

Use a deterministic local adapter for a source walkthrough, then qualify the intended durable adapter separately.

Confirm that a preview, queued delivery, accepted response and completed external effect remain visibly different states.
