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.
The regression for `PresetTree.write` lived two layers up, so this layer's own
assertion could not fail: it checked the file after an ordinary teardown, and
the Loader's unload listener returns early when the whole tree is being
disposed, so the override never ran. Moves the self-disposing-row test down to
the layer that adds the override, in a temp root so a committed fixture cannot
be damaged by the run that proves the bug.
The package landed here with one store spec; the rest of its tests were written
three layers up, so this layer and the two above it failed the per-file
coverage gate on 191 locations while every test passed.
Adds the node half's invariant companion, the two components, the registration
apply, and the stores' failure paths. `currentValue` drops a `?? ''` that an
empty roster already returned before reaching — the same shape the later layer
arrived at, so the two converge instead of conflicting.
Rewrite the three sibling Agent Note pairs that still described create-by-name
as current (workspace-ui-product-flow, session-list-browsing-and-manual-order,
same-basename-workspace-adoption) and the one-route note's own alternative and
section title; delete scripts/hero-composer-dom-continuity.mjs, which drove the
name dialog removed by the one-route change; mark WorkspaceRegistry.create's
now test-only title parameter with a deletion TODO; pin the retired { name }
spelling as a schema rejection; align the workspace spec on stageDir and the
fixture spec title on path creates.
The Web picker collapsed onto the directory flow (see the one-route-to-add-a-workspace
Agent Note), leaving workspace.create({ name }) with no product consumer. Delete the
whole feed line: the wire schema's name member and WorkspaceApi spelling, the gateway's
workspaceRoot config/default and the mkdir branch, the client seam that carried the name
(WorkspaceCreateInput, WorkspacesService.create, intentName), the dsh web
--workspace-root flag, and the fixture's name handling. workspace-name-conflict stays as
workspace.rename's duplicate-title error.
master made `allowParallelInProgress` a required field on dsh-tool-todo, so
every composition must choose it. The base patch was updated with the field,
but the Web surface takes `tool-todo` from the mounted preset instead, and
that row carried no config — so the `standard` preset failed to mount and
every session on the Web surface died at setup.
Also make the preset tree's write test reach the override. Tearing the agent
down stops in the loader's own "tree is being disposed" case before any write;
a live row reconfiguring itself is the trigger that actually gets there.
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.
