imccyu 01ecb43ebc docs: state the Host-face rule for the browser e2e and settle the follow-ups
apps/web/tests/README.md records why these e2e type-check in the Host aggregate
and why importing a Client package there pulls its project tree into the Host
build graph, with mirroring as the standing answer. The Agent Note drops the
directory-picker face split (assessed and declined) and the grep-level gate in
favour of that README.

docs: regenerate the catalogs and retarget the moved declarations

The forwarded-event change moved three owner packages' cordis `Events`
declarations and their branded types into client-safe `./types` modules, and
the settings-scope split moves the shell spec into ui-settings-general. Point
the type-equivalence manifest and the affected Agent Note at those homes,
register the new `remote/*` event scope and the `ctx.settingsScope` service in
the catalog partition, and re-run the generators.

`$on` joins the documented `TypeRTClientRemote` surface, and the two Agent Note
fences that quote a bare member signature are marked `ignore-check`: they are
declaration fragments, not compilable units.

refactor(client): make ui-settings the settings domain's base layer

The settings-namespace transport lived in client/runtime, where every feature
could value-import it because runtime is a platform module. It belongs to the
settings domain, but moving it into ui-settings as a shared function fails
twice: the client bundle purity gate forbids cross-plugin value imports, and
ui-settings reached ui-sidebar for its shell, so any feature depending on it
closed a cycle through ui-layout and ui-theme.

Both halves move. `ctx.settingsScope` is now a cordis service — the
collaboration shape the purity gate prescribes, and the service proxy binds
`this.ctx` to the caller, so a bound scope's disposer belongs to the calling
fiber. The shell ui-settings used to own (the `sidebar.settings` occupant, its
navigation, and the nav-row projection) moves to ui-settings-general, which
already owns the chrome and the General section. What stays in ui-settings is
what carries no `ui-*` dependency: the scope service and the canonical settings
slot types, `settings.general.item` included. That type was parked in the locale
package precisely because the declarer was unreachable without a cycle; every
registrant now depends on this base layer, so it comes home.

The scope CONTRACT stays in client/runtime: a feature service accepts a scope
through its own signature without depending on the surface that binds it.

The forwarded settings invalidation replaces the deleted client-side
`settings/changed` event, so the transport reads `ctx.remote.$on`. It reaches
`$on` through the gateway's Client half plus the allowlist's type-only subpath
rather than api-remotes' Client face: that face imports a Host-tsdown-generated
artifact, and this package is reachable from the Host build graph through its
callers.

refactor(client): reach the settings transport through ctx.settingsScope

Every feature that owns a preference row switches from value-importing a shared
binder to the settings domain's service, and declares the two injections that
binding needs: `settingsScope` for the transport and `remote` for the forwarded
invalidation it subscribes to on the caller's own context.

The rows stay with the features that own the preferences — Language with locale,
Appearance with ui-theme, Composer Enter with ui-conversation. Only their route
to the transport changes, so no settings surface moves and no feature gains a
dependency on the shell.

The `settings.general.item` slot type now arrives from ui-settings, the base
layer every registrant already depends on, which retires the re-export outlet
ui-theme kept and the parked declaration in the locale package.

client/runtime drops its settings-form and schemastery dependencies with the
transport that used them.

test(client): bind the settings transport in the specs that boot a preference row

Every bench that activates a plugin owning a preference row now supplies the two
services that plugin injects: the forwarded-event port and the scope service.
Specs that exercise no settings path get the minimal doubles; the ones that do
drive their refresh chains through `remote/host-event`, the same signal
client/runtime republishes from a forwarded frame, replacing the deleted
client-side `settings/changed` event.

Also fixes a publication defect the built-invariant gate catches once it runs:
api-remotes' invariant companion shared the allowlist module with the package
index, so rolldown hoisted it into a third chunk beside the two bundled entries
— a file the mechanically derived publication list does not carry, leaving an
installed companion unable to import it. The companion now reads the allowlist
through this package's own published `./types` subpath, which the bundle keeps
external, so each entry stays self-contained.

The dynamic-subscription cast in apiproxy is gone: after the vendored cordis
rescope, `on` accepts the rest-parameter handler directly, and the allowlist's
shape assertion still carries the safety argument.

fix(client): carry the settings-scope move across the release manifests

Rebasing onto the publishable release set replaced every manifest's dependency
block, so the packages this change touches restate their additions in the
workspace-protocol form: the base layer's own transport dependencies, and the
`ui-settings` plus `remote` edges each preference-row owner now needs.

ui-settings-general takes clsx with the shell it received, and client/runtime
drops the settings-form and schemastery dependencies that left with the
transport.

fix(api-gateway): give each $on subscription its own registration and containment

Two defects in the forwarded-event subscription table, both raised in review:

A set keyed on listener identity stored one entry when two callers subscribed the
same function object to the same event, so the first frame reached it once instead
of twice and either disposer silenced the surviving registration. Subscriptions are
now records addressed by registration, which is what "the disposer belongs to the
calling fiber" requires.

A listener declared void may still be `async`, and the synchronous `try/catch`
could not see its rejection: the promise was dropped and surfaced as an unhandled
rejection outside the documented containment. Delivery now attaches a rejection
handler when a listener returns a promise, so both failure modes are logged and
isolated alike.

Delivery also iterates a snapshot, so a listener that subscribes or disposes during
a frame no longer changes who receives that frame, and production matches the
TestRemote double instead of relying on live Set iteration order.

Both fixes are pinned by tests that fail against the previous implementation. The
double gains its own spec for the `$mount` refusal and the unsubscribed-name drop —
per-file coverage reaches it — plus a note that it propagates a throwing listener
where production contains one, so no spec mistakes it for the containment guarantee.

Three prose corrections: `assertJsonArgs` states where its throw actually surfaces
(the emitter's listener containment, not load or emit time), the browser e2e README
names every standing Client import rather than claiming one exception, and two
comments and a test title state the forwarded event instead of the deleted
client-side one.

refactor(remote): deliver forwarded frames through ctx.remote.$dispatch

The carrier used to relay each decoded frame over an internal
`remote/host-event` cordis event so the delivery port could stay off the Remote
contract. The relay was the wrong shape twice over: it put a client-face event
into a scan whose subject is the Host vocabulary, forcing a walk exemption for
something that is not a Host event at all, and it made a direct handoff between
two Client plugins look like a broadcast any plugin participates in.

`TypeRTClientRemote` now carries both roles of one surface — consumers subscribe
with `$on`, and whoever owns the Host frame sink hands frames over with
`$dispatch` — so client/runtime calls the Remote service directly and the event
declaration is gone. A cordis service method is the collaboration shape the
client bundle purity gate prescribes, and it needs no relay to satisfy it.

The trade is that the handoff is now developer-visible: any plugin holding
`ctx.remote` can synthesize a forwarded event. That is the exposure the relay
already had — `ctx.emit` was equally reachable — stated in the contract instead
of hidden behind a private subscriber.

runtime reaches `ctx.remote` through the gateway's Client face rather than
api-remotes': that face imports a Host-tsdown-generated artifact, and this
project sits in the Host build graph.

refactor(api-remotes): keep the allowlist value out of types.ts

`src/types.ts` carries only types by package convention, but it held the
forwarded-event array, so the type-only subpath published runtime code. The
array moves to `src/remote-events.ts` and `types.ts` derives its projection from
it; both compiler faces list both files, so the Host forwarding loop and the
consumer key face still read one declaration and the package's exports are
unchanged.

The invariant companion returns to an empty installer. Its dispatch-shape check
was the only reason the companion imported the allowlist, which made the two
bundled entries share a module: rolldown hoisted it into a third chunk that the
mechanically derived publication list does not carry, so an installed companion
could not import it. Dropping the check retires that coupling along with the
subpath-import and bundle-external workarounds it needed, and the shape the
check enforced at runtime is the part the Host face's `TypeRTForwardableEvent`
assertion already refuses at compile time.

test(ui-task): bind the locale plugin's new injections in its bench

The bench boots the real locale plugin, which now injects the settings-scope
service and the forwarded-event port, so it stayed pending and left `ctx.locale`
undefined. Supplies both doubles like the other benches that boot a plugin
owning a preference row.

docs: close the documentation gates for the forwarded-event surface

Regenerates the two graph catalogs and re-records every bilingual pair this
branch edited. Several pairs needed real work beyond the record:

- The generators write only the English side, so the Chinese sides of
  `event-producer-consumer` and `module-graph` had drifted: the former still
  listed the three deleted client-face events and pointed at declaration sites
  this branch moved into `types.ts` modules, and the latter carried a stale
  dependency graph.
- `TypeRTClientRemote`'s documented declaration gains `$dispatch` on both sides.
- The pairing contract requires both sides to link the same target, so the
  apiproxy README and the design note now link the English note from both
  languages, and the note's code blocks are byte-identical across the pair
  (a translated comment inside a fence counts as divergence).
- `apps/web/tests/README.md` gains its Chinese counterpart; the browser e2e lane
  documents a discipline reviewers apply, so it belongs in the bilingual corpus
  rather than in the pairing exemption list.
- Four fences in the design note are marked `ignore-check`: each quotes a member
  signature, a union arm, or a snippet that names symbols it does not import, so
  none is a compilable unit.

docs(agent-note): transition the forwarded-event note to implemented

The design shipped in this PR, so the pair moves into `implemented/` and takes
that folder's skeleton: `## Proposal` becomes a present-tense `## Decision`,
and `## Acceptance criteria` plus `## Risks` fold into `## Verification` (what
pins the behavior) and `## Consequences` (what the shipped shape costs).

Facts that moved after the proposal are corrected rather than preserved: the
allowlist value now lives in `remote-events.ts` beside a type-only `types.ts`,
the delivery port is `$dispatch` rather than an internal cordis event, and the
invariant companion is an explained empty installer. `Verification` states the
two `$on` defects the review found — independent registration identity and
async-rejection containment — since those are now the properties tests pin.

Supersession is partial, so five active notes stay active and gain a
cross-link each: `web-config-plane`, `web-client-session-scope`,
`config-plane-boundaries`, `versioned-gui-welcome-onboarding`, and
`permission-default-for-new-sessions` each described a frame this change
replaced. Only the mechanism sentence is annotated; every conclusion those
notes own is untouched, and `host/models-changed` remains apiproxy's own
derived frame in all of them.

Also pins the disposer's idempotence: calling one `$on` disposer twice must not
splice a surviving twin registration out from under its owner.

Agent Note: Versioned GUI welcome onboarding

Status: implemented

English | 中文

Problem

The GUI's credential onboarding begins with a DeepSeek-specific readiness check, but the internal-test notice applies to every user and must precede provider setup even when a credential is already configured. Treating both as independent overlays permits simultaneous dialogs, while a process-local dismissal cannot distinguish a completed notice from a window closed before acknowledgement or intentionally present revised copy once.

Decision

The Settings shell coordinates ordered steps. settings.onboarding remains a root-scoped list, but ui-settings projects its entry ids and order into one coordinator and mounts only the first incomplete step. The active registrant receives complete() and openSection(id); no later step mounts until ownership transfers. The product welcome registers at order -100, while ui-models retains only the conditional DeepSeek readiness and credential-routing step at order 0.

Ownerless product onboarding belongs to ui-settings-general. src/onboarding-copy.ts is the single editable source for the complete notice, the Continue label, and WELCOME_NOTICE_VERSION; both supported GUI locales intentionally render the same Chinese owner copy. Runtime locale dictionaries derive their welcome values from that file, and tests import the same owner instead of repeating paragraph text. The notice is browser UI only: it creates no Session event and contributes no model-visible content. The notice identifies DSH_TELEMETRY_DISABLED=1 as the telemetry opt-out.

Loopback acknowledgement is durable per Harness profile. The Host half registers a ui-onboarding section in the user-settings seam, stored under the active $DSH_HOME/settings.yaml. The connection plugin publishes whether the current page uses a loopback authority as ctx.connection.isLoopback; hostname classification remains internal to the connection package, and other client plugins consume the service state instead of importing its implementation. A loopback browser shows the notice unless welcomeNoticeVersion equals the owner constant exactly. Continue applies one path mutation with the current version and calls complete() only after the Host commits it; a failed write leaves the notice open, and closing the page or process writes nothing. Bumping the constant intentionally makes every profile acknowledge the revised copy once. A non-loopback browser must not call the loopback-only settings API. It presents the same notice, but explicit Continue completes the step only in the current browser process; reload or a new process presents it again.

Concurrent loopback views converge without stale replacement. The acknowledgement write omits expectedRevision deliberately: every loopback tab writes the same version to one path, so the operation is idempotent and preserves sibling fields instead of rebuilding the section. settings/document-updated reaches the client as an invalidation — through host/settings-changed then, and forwarded verbatim now (forwarded Remote events); an already mounted loopback tab refetches and advances when another tab or an external editor commits the current version. The API proxy exposes this one product namespace through a closed allowlist beside configurable-provider namespaces, without treating its changes as model-catalog invalidations.

Onboarding temporarily owns the viewport as one continuous stage. A solid product surface replaces the complete application view through a body-level portal and marks the underlying app root inert; the exact required mask remains mounted behind that surface with position:absolute, zero left/right/bottom offsets, top:80px, rgba(0, 0, 0, 0.24), and backdrop-filter: blur(2px). Welcome and conditional credential setup render as successive pages in this stage instead of independent modals. Both pages reuse the Web UI's black BrandWordmark. The welcome page preserves the four authored paragraphs verbatim under the 内测声明 title; every paragraph uses one 16/28 body scale, and only the requested action clause inside the final paragraph receives a subtle 500 weight. A short staggered opacity/vertical entrance supplies pacing without blocking interaction and disappears under reduced motion. The title receives initial focus, Continue is the sole button, and no close, Escape, or mask-click path exists.

Alternatives considered

Browser local storage — rejected because acknowledgement would follow one browser profile rather than $DSH_HOME; a fresh Harness profile could incorrectly inherit a prior acknowledgement, and external profile edits would have no authoritative update stream. Non-loopback fallback therefore remains process-local rather than browser-profile-local.

A second independent modal in ui-settings-general — rejected because list registrants would still stack whenever welcome and credential readiness were both true. Ordered ownership belongs to the shell that declares and renders the list.

Persisting on render or window close — rejected because observation is not acknowledgement and close delivery is unreliable. Only the explicit Continue commit may suppress the next launch.

A generic public settings-exposure flag — rejected because one product namespace does not justify widening every settings registrant's public configuration surface. The gateway keeps an explicit closed allowlist.

Consequences

A fresh profile always sees the welcome notice before provider-specific onboarding; an already configured credential skips only the later DeepSeek step. On loopback, reloading after Continue stays past the acknowledged version, changing the owner version presents it again, and closing before Continue leaves the next launch unchanged. On non-loopback, Continue advances the live process without a privileged settings request and reload presents the notice again. Focused store and React tests pin both persistence modes, exact-version comparison, write failure, sole-action behavior, no-dismiss paths, coordinator ordering, conditional DeepSeek transfer, and HMR cleanup. The real Chromium scenario boots the shipped Web composition with an isolated harness home, verifies the exact mask geometry and computed styles, reloads before and after acknowledgement, continues into missing-credential setup, confirms an acknowledged-version mismatch returns while the credential is configured, and checks the browser console.
