Yichen Jiang 5a90eb41fb fix(ui-models): three faults the running app surfaced
**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.

client/ — web-GUI browser half

English | 中文

Package Purpose
web/ Boots the browser shell from the client entry graph.
modules/ Loads browser-side client modules.
web-react/ Connects the shell runtime to React rendering.
connection/ Maintains browser-host RPC communication and event delivery.
runtime/ Provides shared client services for sessions, workspaces, and UI composition.
hmr/ Refreshes client plugins during development.
locale/ Provides localization preferences and message dictionaries.
schema-form/ Provides schema-backed draft handling for settings editors.
test-runtime/ Provides shared repository test support for client feature packages.
ui-slots/ Defines how UI features register and compose extension slots.
ui-theme/ Applies the selected color theme.
ui-primitives/ Provides shared React controls, icons, and content renderers.
ui-layout/ Arranges the main application regions.
