- resolveLlmRoute: reuse the yml pi-ai row for providers it already routes
(DUPLICATE_ADAPTER boot failure) and detect an unset model by origin, not
by comparison against one deployment default; covered by a new spec.
- LlmService.resolveModelInfoFor preserves (and validates) modality
metadata, arming the host image preflight for exact-route resolution.
- session.selectModel refuses a text-only target once the session log
carries an image on any replayed route; an accepted switch would strand
every later turn with no in-product recovery.
- The composer no longer gates image intake on the handshake activeModel
snapshot (wrong authority for a per-session decision); the host preflight
plus the error strip own capability, deployment limits stay client-side.
- InputHub shell teardown releases the scope's draft images (File objects
and object URLs leaked for the page lifetime).
- session.prompt image parts carry optional alt into the durable block;
ImageBlock documents assistant-side rendering as forward compatibility.
- Assembled built-client lane apps/web/tests/image-display.snapshot.ts pins
the history galleries over the authorized attachment route, the lightbox,
and the composer paste rail; the attachment rail is an accessible group.
- Docs: validateImage on the seam page, fixture byte metadata matches its
PNG, and the Agent Note claims now match the shipped coverage.
- 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
