**Reasoning effort leaves the provider cards entirely.** It is a per-MODEL
capability and the models under one provider disagree about which levels
they accept: setting `anthropic` to `max` made six of its eight models
throw UNSUPPORTED_REASONING_EFFORT, and because the catalog build catches
per provider, the whole provider vanished from the picker behind one error
row. A provider-scoped control can only ever be set to a value some of its
models reject.
The composer's model picker already offers each model its own levels, and
a switch there now records provider, model, and effort together as the
next session's default — so the setting has a better home at the right
granularity. The profile field stays in `settings.yaml` for a deployment
that knows its route; only the control is gone, from both cards and both
adapter families. Two `components.spec` cases used the control as the
vehicle for their op assertions and now use `baseURL`, which is what they
were actually testing.
**A rejected Provider ID now reads as a fault.** It shared the neutral
hint paragraph with the field's guidance, so the copy telling the user
what they got wrong looked like advice. Reuses the existing `.error`
style, matching the split the key field already makes.
The line under the create form names the one blocked gate worth naming,
and its fallback arm reads "no models yet". An unmet Provider ID gate fell
through to that arm, so a card with two models listed right above it was
told it needed one. The key gate was already excluded for this reason; the
route gate was assumed excluded because its field explains itself, and was
not.
Tightening the route rule in the previous commit is what made this easy to
hit — a digit-leading id now fails the gate — but the fallthrough predates
it and fires for an empty or taken id just the same.
**A hand-declared route must not offer a reasoning effort.** The earlier
commit read the create card's missing control as drift and added one. It
is the other way round: such a model has no reasoning capability — pi-ai's
installed catalog is what supplies one, and it ships nothing under the
route — so `resolveModel` throws UNSUPPORTED_REASONING_EFFORT for every
model on it and the whole provider drops out of the picker. Verified
against the adapter, not inferred. The create card no longer offers it and
the editor withholds it on the directory's `declared` bit, which is the
real bug: that control has always been wrong for these routes.
**A blocked composer locked the way out of the block.** Reusing the
no-workspace inert posture disabled the model seat along with everything
else, so the bar asked for a model while preventing the one control that
picks one. A block now rides its own `blocked` owner prop: the textarea,
send, commands, plan seat, and access chip all lock, and the model seat
alone stays live.
**A Provider ID could derive an illegal credential reference.** The card
accepted a digit-leading id, whose derived `123_API_KEY` then failed at
the credential seam with a raw regular expression the user cannot act on.
The id must now start with a letter, and a test pins the relation between
the two rules rather than the regex.
Carries two edits beyond conflict resolution, both forced by what master
brought in:
- `CustomProviderCard`: master added front-end key validation and a
component-level `keyValue` (already trimmed) while still writing
`apiKeyEnv` unconditionally. Kept this branch's blank-key rule and its
committed-profile retry gate, and adopted master's single `keyValue` so
the component has one spelling of the key rather than two.
- `docs/user/guide/providers`: master merged #1810, whose default-model
section still taught overriding the `api-gateway` row in
`$DSH_HOME/config.yaml` — the behavior this branch replaced. Rewritten
for the settings section the picker now writes, plus the review fix from
#1810 replacing the colloquial 挂着 in the opener.
A default naming a route the Models page has since removed left the
composer saying 选择模型 while the input still accepted a message, which
then failed inside the adapter mid-turn.
`session.prompt` now refuses with `model-unavailable` before opening a
turn. That is the enforcement boundary: the method stays callable no
matter what a client disables. `session.models` reports the same fact as
`routable`, and ui-model pushes a block through the new
`ctx.conversation.blocks` registry so the bar renders the disabled
textarea it already renders without a workspace, carrying the blocker's
own reason. The push direction is forced — ui-model already depends on
ui-conversation, so ui-conversation cannot read it back.
The gate is `routable`, not "matches no advertised group": catalog
membership is advisory, so a route serving a model it stopped advertising
is missing from the groups yet perfectly usable, and `null` before the
first load never blocks so a slow Host cannot lock a working composer.
The scaffold gains a route-only adapter for fixture-less keyless
scenarios. Registering zero providers is a test artifact — every product
composition mounts one — and the goldens that froze the seat's fallback
label now show the model those scenarios actually route to.
Master's credential-lifecycle work taught the editor card that a pi-ai
profile names `apiKeyEnv` only when a key is actually stored, so a route
left blank keeps its provider-native auth path. The create card kept
writing the derived reference unconditionally, so a route declared for a
credential chain or ADC was born pointing at a reference nothing sets —
and now rendered a red missing-key dot for it.
Both cards apply one rule. The obsolete assertion moves with the behavior
(the with-key case is covered by the neighbouring test), and the merged
Models e2e golden shows the declared route unmarked rather than flagged.
A row's stored profile could not tell a hand-declared gateway from a
shipped provider whose models someone narrowed — both look identical from
outside the adapter — so the Models page had no way to mark the routes a
deployment added itself.
The directory entry now carries `declared`, answered by the owning adapter
against its own installed catalog, and the page renders a Custom tag from
it. Absence stays "this adapter draws no such distinction" rather than
"shipped", so a route no adapter claims is labelled neither way.
Also records the default-route work's Agent Note and the e2e evidence for
all three changes: the composer switch writing the section, and the Models
page declaring a route with its own reasoning effort.
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.
The create card omitted the provider-level effort the editor card offers
for the same namespace, so a route declared through 添加自定义提供方 gained
a setting the moment it was reopened for editing — one the creating user
was never shown.
Both cards now render one shared control. The field, its vocabulary, and
the inherit-means-absent rule live with the control rather than in the
editor, which is what stops the two from drifting apart again.
