made-api

The published contract of the embedded MADE by Underpass engine — what a consuming product is allowed to know.

Plain views, a capability report, an error vocabulary and one trait. No domain types, no adapters, no storage. A consumer that compiles against this crate alone can be developed against a stub and later pointed at any implementation that honours the same contract.

Versioned by meaning

CONTRACT_VERSION moves when the meaning of this surface changes, and it is deliberately independent of the crate's release number. Two builds of the same release can differ in the features they were compiled with, so a consumer that inferred capabilities from a version string would find out it was wrong mid-run.

Check ApiCapabilities at startup instead: it reports what the engine you are actually holding can do.

Vocabulary

These types speak the engine's own language — councils, ceremonies, steps, guards, interventions. Nothing of a consuming product's vocabulary appears here, and nothing of this vocabulary needs to leak into a product: the mapping belongs at the consumer's own boundary (ADR-001 in the repository).
