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.
- ui-model README pair (short-form Model Experience + audited registry
entry + Known Limitations), recorded in the pairing manifest
- llm-deepseek README pair rebased onto master's version with this PR's
real deltas (friendly names, 256k, selector consumers) on both sides;
runtime/ui-conversation READMEs revert to master (their sections
documented the removed Session state machine and control slot)
- config catalog regenerated for the ui-model roster row
- ModelDirectory.store JSDoc; ui-model files join the TODO(gui) coverage
deferral lane beside their ui-command/ui-slash siblings
- unused SessionId import and an unnecessary assertion in ui-model
- two over-length fake-api lines split
- trigger chrome calibrated against figma 313:14108's ToggleButton
(13/20 medium secondary at 28px; chevron in label-caption = the mock's
#ADB2B8; the mock's leading icon is invisible there, so the seat has
none, and its 'High' effort text has no wire concept to render)
The original ModelSelector returns as the conversation.input.model seat
occupant (the named single slot the composer bar renders before its primary
button), alongside — not instead of — the /model popup. Both entries are
projections of ONE per-session directory owned by the new ModelService
(ctx.models): the same session.models load, the same selectModel submit,
the same host-reported current — a switch in either entry is what the
other shows next, asserted both ways in the plugin spec.
Trigger chrome follows figma 313:14108's composer ToggleButton (13/20
medium secondary label, 4px gap, caption chevron, 28px chip height
matching the sibling Plan/Read-only selects); the menu keeps the original
upward provider-grouped single-select with keyboard navigation. The
seat honors the owner locked bit as its disabled state.
- host trio kept on the merged api-proxy: session.models (provider-grouped
advisory directory), session.selectModel (validated provider, advisory
model), installAgentLlmTarget threaded through create/resume/ensureSession;
the gateway declares the llm inject it reads
- history no longer piggybacks modelTarget: the current target travels on
session.models alone (the /model popup is the sole consumer)
- new @deepseek-ai/dsh-client-ui-model plugin: /model popupSelect over the
wire — options load the directory (group label in the detail column,
provider-local failures listed inline), onSelect routes selectModel;
failures ride the popup shell's error/retry surface
- ModelSelector package, conversation.composer.control slot, and the
Session-side modelSelection state machine are removed: model selection
belongs to the /model popup; the named conversation.input.model seat
stays empty until a control-seat entry is designed for it
