The seat's dropdown follows figma 496:26454: the root pane is the Model / Effort cell pair (14/22 label, value in the tertiary tone, right chevron), each drilling into its own list — the provider-grouped model list over the shared directory, and the High/Max effort levels. The trigger (313:14108) shows both values: model name plus effort in the caption tone. Effort is a client-local display echo on the shared directory state for now — the design pairs the two as one selection, but no wire carries a per-session effort override yet (the deepseek adapter's reasoningEffort is deployment config); the directory state documents that boundary, so wiring it later is a submit-path change, not a UI one. Escape backs out of a drilled pane before closing.

Model selection plugin, browser half: TWO entries over ONE per-session directory owned by ModelService (ctx.models). The /model popupSelect contribution (registered through ctx.command) and the composer's named conversation.input.model seat (a compact trigger + upward provider-grouped menu, figma 313:14108's ToggleButton chrome) both load the session's advisory directory through session.models and submit through session.selectModel via the same ModelDirectory instance — the host-reported current target is the single fact both surfaces echo, so a switch made in either entry is what the other shows next. Directory loads and selections share a generation counter (an older response never overwrites a newer one); provider-local catalog failures list inline while usable groups stay selectable; whole-request and selection failures surface on each entry's own retry face (the popup shell's error/retry, the seat menu's inline error) without forking the state. Directories are per-session, resolved lazily through ctx.models.directoryFor(sessionId), and disposed with the session scope.
The /client export surface is the plugin body (apply/inject), ModelService, ModelDirectory with its state shape, and the seat's injected face type.
Model Experience
Indirectly, through the session.selectModel RPC both entries submit: the host snapshots the selected provider/model pair at the next prompt-assembly boundary, so the following request routes (and stamps its prompt variables) with the chosen target while a running step keeps its assembled one — the directory, both menus, and every selection interaction stay client-side and never enter the session log.
KV Cache effect
Switching the route can reduce or invalidate provider-side cache reuse for subsequent requests; the prompt prefix itself is untouched.
Known Limitations and Deferred Work
- No create-time selection — both entries address an existing session's agent; there is no draft-phase model choice to fold into session creation (the seed order at the host's
targetFordocuments where such a tier would go). - Directory names are presentation-only — selection and persistence use provider/model ids; a provider whose catalog lookup fails lists as an unselectable failure row until reload.
- The seat shows no effort level — the figma mock's
Hightext has no wire concept behind it yet; the trigger renders the model name alone.
