Public snapshot state stays in the store engine's plain-data vocabulary
(immer drafts reject Sets without the MapSet plugin, which stays off):
manager/service/contract carry readonly SessionId[] in Host order, and
the tree derivations build their own transient Set — the
expandedProjects pattern. Membership-unchanged installs still keep the
array reference for Object.is short-circuits.
WorkspaceListState gains archivedSessionIds (ReadonlySet, replaced only
on membership change), installed as full snapshots from the list
baseline, the unary echo, and the changed frame. Archiving the current
session clears the selection into the New Session view state. Test
doubles (test-runtime, fake APIs, fixture client) follow the widened
IWorkspaces/IApiClient faces.
Registrations declare a dictionary namespace (locale: NS) and the renderer
synthesizes a typed t prop for the entry's component from the installed
LocaleFace; the seat binding is re-derived per locale revision, so a language
switch hands out fresh t references and memoized consumers re-render through
ordinary shallow comparison. LocaleNamespaceMap is the declare-merge table
(namespace -> dictionary key union); TranslateNS<'ns'> is the
namespace-addressed translate type (namespace keys plus the shared common
vocabulary), carried by the t seat and by the locale service's typed bind.
LocaleService implements the face (lookup ns -> common -> zh -> key,
revision-carrying snapshots with subscriber isolation) and installs it
through the boot-once slots.installLocale seam, mirroring the renderer
install. The typed register(ns, {zh, en}) overload checks each dictionary
against the namespace's key union and requires every shipped locale, so a
missing or extra key and an unbalanced translation are compile errors.
Dictionary registration bumps the face revision without emitting
locale/change — the event now means exactly 'the active locale switched',
so registration-heavy boot cannot storm event listeners.
Locale and ui-theme apply coverage on a real Context + SlotCore:
dictionary assembly, declaration-aware registration both ways,
inject-time getter re-sync, service write-back through the event flow,
HMR collapse recovery, and teardown reclamation. Four settings-surface
packages sit at full per-file coverage.
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).
Replace optional chains on always-present globals with the repo's
typeof guards (store.ts precedent), drop the non-null assertion by
failing loud on an impossible registry miss, and fix two arrow-parens
slips; cover the no-localStorage boot path in both service suites.
Add the browser Settings surface as slot-composed plugins over new
preference services:
- Rename dsh-client-i18n to dsh-client-locale (locale is the domain
name); LocaleService adds getLocale()/setLocale(id), immutable
snapshots, a locale/change event, and dsh.locale persistence.
- ThemeService owns the light/dark/system preference (default system),
resolves system via prefers-color-scheme, publishes theme/change
snapshots, persists dsh.theme, and no longer touches the DOM;
ui-layout's ThemePresenter applies resolved snapshots
(body[data-ds-dark-theme] + alias tokens) and cleans up on dispose.
- ui-sidebar drops the phase-1 settings dropdown/modal; the foot renders
the new sidebar.settings slot with the column state.
- New ui-settings shell occupies sidebar.settings: foot trigger row and
the centered 1080x700 panel (figma 501:29947) with 24% mask, close
button / mask click / Escape all closing, and a 188px nav projected
from the settings.section list slot it declares. Nav labels are
registrant-localized; sections re-register on locale change, so the
ledger version is the shell's only subscription.
- ui-settings-general registers the General section: Permission and
Tool Call skeletons, live Language (locale menu) and Appearance
(Light/Dark/System cubes following the persisted preference); its
slot store mirrors both service snapshots via apply-side listeners.
- ui-settings-models registers the Models nav entry with an empty
content column.
- Portaled menus pin z-index above modal overlays (a menu anchored
inside the settings dialog rendered underneath it and was
unclickable).
- theme/data/list-pen icons in ui-primitives; settings copy ships as
zh/en dictionaries; fixture manifests gain the settings rows.
