S3 + V3 + R3, built. Every frame below is the same live component under different props, so the geometry in the handoff tables is measured from what you are looking at rather than described beside it. Visible copy is the existing resource text in both locales; every catalogue value is the inspected fixture. Three Compose surfaces change; nothing else does.
The page keeps its exact sequence: default agent, new-session permission mode, default model scoped to the selected agent, default effort scoped to the selected agent, conditional Fast, context window presets and custom, per-model windows, agent filter. Every existing callback fires from the same row it fires from today.
The addition is one read-only low container directly under the title. It prints existing group labels against currently stored values and owns no string of its own — no heading, no framing sentence, no derived text. It is not focusable and consumes no target budget.
Fast appears in the summary only while a priority model is selected, matching the row's own visibility rule. Omitting it under priority would let the summary imply a complete launch configuration while hiding one of its defaults.
The two-layer composer is unchanged: full-width multiline field above an accessory row. What moves is the written state — the existing queue, upload and transcription-failure strings now sit in one ribbon slot above the field, so the reason a control behaves unusually arrives before the control.
One restrained mark separates informational from failure by shape — a small dot against a square — so the distinction survives greyscale. The ribbon is a live region; it announces on change and never on every recomposition.
Transcript, context disclosure, Quick Actions, Model Picker, recording behaviour and the desktop composer are all untouched. No predicate changes: the same conditions that produce each control today produce it here.
Both groups are FlowRows, so the leading group re-wraps internally at 280 dp before the outer rule fires. Controls never shrink below their minimum; the lane grows in height instead.
