ChatView's bottom-follow recognized only wheel gestures as reader input,
so touch panning, scrollbar dragging, and keyboard paging could not leave
the bottom of a streaming transcript. Replace the wheel listener with
device-agnostic attribution: a scroll position deviating from the
observed-top ledger of the last delivered or written scrollTop is reader
input. Adds keyboard-paging and touch-style fling e2e scenarios (red under
the old implementation) and the bilingual Agent Note triplet.
The hero Preview tag becomes a superscript mono pill riding the title's
top-right (r24, bordered, business-tertiary fill), colored by the new
--dsw-alias-label-primary-bluish alias over --dsw-static-blue-900 — the
first design-owner-approved addition under the token-sheet authority
exception recorded in the ui-theme README. The expanded sidebar trigger
now uses the native 16px settings icon instead of the 14px asset.
ui-conversation now owns only the conversation.chat.turnTail hole; the row,
its derivation, and its copy live in @deepseek-ai/dsh-client-ui-deliverables,
composed in or out by one cordis.yml line.
knip: ui-settings no longer imports react-dom (the portal moved into
OnboardingSurface), so the react-dom peer/dev dependencies and
@types/react-dom go away with the usage.
Review follow-ups: the Agent Note's Testing section now records the
held-join reload regression scenario this PR adds (both languages,
pairing re-recorded); the e2e hold gates EVERY settings.describe issued
before release instead of only the first, so a future boot-time join
consumer cannot silently collapse the widened window; the sampler's
persistence across later navigations is documented and the vacuity
wording softened to what the hold actually buys (timing independence).
The settings shell painted the onboarding overlay (opaque stage, mask,
#root inert) the moment a step was registered and not locally completed,
while every step still had to load its private join before deciding
whether to show — rendering null could not suppress the shell-owned
chrome. Every reload on the hero therefore flashed a full-screen opaque
layer (white in the light palette) for one settings/credential RPC
round-trip after the session list turned ready.
The chrome now belongs to the step: a new zero-cordis OnboardingSurface
primitive (ui-primitives) renders the body-portaled overlay/mask/stage
verbatim from the former SettingsRoot stylesheet and holds #root inert
for exactly its own lifetime. WelcomeNotice and DeepSeekOnboardingDialog
wrap only their visible branch in it, so their existing null branches
paint and block nothing by construction. SettingsRoot keeps the
coordinator unchanged but renders the elected step bare, and the
settings.onboarding contract now names the surface wrap as the
registrant's obligation.
The onboarding e2e gains a held-join reload scenario pinning that a
configured world never mounts the takeover chrome or inerts the app.
