One declaration does three jobs: renders the panel, carries the defaults, names
the values that come back. A module writes no DOM and reads no DOM.
Validation refuses rather than repairs -- unknown type, a renderer its type does
not have, a label that is not text, a default outside its own bounds, a when
naming a key the module never declared. A module that is wrong does not get a
best-effort panel; it does not load, and says why once.
Ordering is by declared relation and stage, never priority numbers, and a cycle
drops only the modules in it. Compatibility is by trait, never model name.
The shell hands a module { composer, values, on, shell } and nothing else: no
node, no document, no kit internals. It cannot style anything because it is
never given anything that could.
catalogue/hide.html puts one good module and five broken ones through the real
shell and shows the result: one panel, five absent, no placeholders. The lint
fixtures make the scanner prove it catches each rule, so a clean scan means
something.
First slice: modules/system/appearance. Two settings, an optional ui.js, and
clicking Light actually turns the app light.
55 element groups across text, buttons, choice, input, slider, layout, status,
overlays, gallery and the wheel picker. Each lands in a registry-driven
catalogue that shows every variant in both themes, so an element that fails to
register is visibly absent rather than quietly missing.
rule_content_is_data iterates the REGISTRY, not a list: a new element is
attacked with markup the moment it calls define(), and one without a demo fails
the suite. That is announcement-not-enumeration applied to the tests.
Fixes found while building: checkbox silently ignored its label (inverted
logic left it with aria-label=toggle), the overlay root set z-index 0 and so
became a stacking context that trapped every overlay it was built to free, and
raising a window left its peers' z stale because z is derived from position --
claim() now notifies a rung when a peer moves.
The wheel highlights the actual sector rather than a box around the label: the
lit shape is the region that picks the item, which is what makes it aimable.
