Service Contracts Are Next

The service-form internals are tested, but the CLI still needs configuration loading.

Update, 2026-07-04: the signup story landed and then evolved: the first external-source tile shipped as a vendor form, and 0.8.0 replaced it with the newsletter tile, which posts to a site-owned subscription API and keeps every vendor out of the page. General service contracts still need hosted proxy plumbing.

The engine already has service contracts and service-form rendering tests. A service-form tile can bind to a typed operation contract, render browser-safe HTML, and avoid leaking server credentials.

The CLI does not yet load service bindings from tiledown.yml, so this public site does not render a live service form. That is intentional: the missing work is configuration and deployment plumbing, not a hidden demo path.
