What it means
The website's homepage, its /features/ pages and its capability matrix name no feature, no
capability module, no public command, no provider and no count. Every one of those comes from
site/data/registry/product.json, which the executable writes from the features of the layer,
the capability registry, the command registry, the Why catalogue and the web topology. The
only hand-written words on the surface are positioning sentences and button labels in
site/data/marketing.toml, held to a line budget and carrying no number and no capability
claim.
A stale dataset cannot be deployed: majordomus generate --check fails a tree whose
product.json does not match the repository, so the homepage cannot describe an executable
this repository does not have.
How it works
The templates read the dataset and render it. scripts/site-check decides the rest: it
refuses a template, a generator, a jq program or a navigation file that names a feature route
or a provider's own bootstrap or client-configuration file; it proves every public feature has
its page and every page under /features/ was produced by a feature; it compares the marks
the matrix page shows with the marks the model derived, both directions; and it checks that
the telemetry the homepage prints is the dataset's.
Routes that moved are declared once, in nav.toml under [[redirects]], and become Zola
aliases on the page they point at; a redirect whose target the generator did not produce fails
the build rather than publishing a link into nothing.
How to see it
scripts/derive && scripts/derive-check # the dataset matches the repository
scripts/site-build && scripts/site-check # the page matches the dataset
bash test/run.sh 12_site_buildWhat it does not cover
Which features are chapters of the homepage and in what order is editorial, and is declared in
the feature files themselves (featured, weight) rather than in the page. The positioning
sentences are written by a person; what is checked is that they carry no number and no
capability claim, not that they are true.
Why it exists
The homepage was the last hand-maintained inventory in a repository where every other surface is a projection. The gap between what the product did and what its public face said grew in exactly the direction nobody measured, because nothing could fail when the two disagreed.
