The shell is now a pure composition face: no dictionaries, no locale
dependency, and three new chrome content seats (settings.trigger /
settings.header / settings.close) whose slot content also carries the
accessible names (trigger text, dialog aria-labelledby, visually hidden
close label). ui-settings-general returns as the owner of copy that
belongs to no single feature: chrome content, the General section with
its item slot, and the settings dictionaries. Slot types split homes —
trigger/header/close/section live in the shell contract; the
settings.general.item entry moves to the locale package (the common
dependency of every item registrant), with ui-theme consuming it
through a re-export seam; the verbatim duplicate merges are gone and
the dependency graph is a clean DAG.
deferRegistration() stays the shipped form; the note pins the follow-up
direction (bridge declarations into slot:<name> services, migrate
registrants to nested ctx.inject, delete the helper) and the boundaries
a separate PR must settle.
Generated docs follow the ui-models rename and the removed
ui-settings-general package; the English note side picks up the
feature-owner self-registration doctrine.
Settings collaboration direction (recorded in the note): the shell only
provides composition faces — feature plugins register themselves. The
General section moves into the ui-settings shell (order 0, skeleton
rows) and declares the settings.general.item list slot; locale registers
the Language row and ui-theme the Appearance row (each with its own
store mirror, dictionaries, and ledger-judged deferral); the
ui-settings-general package is gone. ui-settings-models becomes
ui-models — a feature package that contributes its Settings section
rather than a settings-owned satellite. The item-slot SlotMap entry is
authored in the ui-settings contract and repeated verbatim in
locale/ui-theme (reference-cycle avoidance; declaration merging keeps
the copies identical).
Both sides of the bilingual pair compile in one doc-typecheck program;
module-scoped (exported) declarations keep the shared identifiers from
colliding across the pair.
Regenerate the module-graph/config-catalog/event-graph docs for the
locale rename and new packages; allowlist the three settings READMEs;
complete the RFC code block and add its English pair. Cover the
ThemeService media-query paths (stubbed matchMedia) and mark the
unreachable registry fallback. General section re-registration now
judges presence on the slot ledger instead of a local disposer, which
went stale when an HMR collapse removed the entry.
