| Ten stable numbered inputs; no silent reassignment or shifting thumbnails | Sources list + source assignment inspector | Shown in proposal; native identity/churn validation still required |
| Source categories and clear source type | Category filter, row kind and source picker | Restored in revision 2; all enabled adapter kinds must remain |
| Observed source resolution, frame rate, liveness and meters | At-a-glance rows + selected-source detail | Illustrative values only; distinguish requested from observed in app |
| Quick Multiview inclusion, independent of scene Take | Per-row MV checkbox + inspector | Restored in revision 2; route/Program invariance requires app test |
| ISO arm/record state, routing and recording readiness | Quick source status + existing Routing/record controls | Destination incomplete in proposal — must review before replacing page |
| Zoom camera max resolution and local guest FPS preference | Source/meeting quality settings, discoverable from Sources | Not mocked — must retain values and existing semantics |
| Capture setup/reconnect, paired audio, sync offset, SRT/RTMP/browser setup | Source management and existing adapter-specific controls | Not fully mocked — no adapter or control removal authorized |
| Source-bound lower-third text, blank secondary override and saved looks | Text in Sources; appearance in Overlays | Existing behavior retained; persistence/output regression tests required |
| Visual color pickers plus optional exact hex, sliders/units/reset | Shared color entry and adjustment controls | Picker entry demonstrated here; Windows/high-DPI interaction still open |
| Scene layers, Tiles members/style, transforms, crop/fit, drafts, Take, saved routes | Existing Scene Builder workspace | Reused, not replaced by Sources; verify saved/custom routes survive |
| Grade stack, curves, presets/LUTs and scopes-only drawn ROI | Existing grade workspace | Keep live-edit choice; verify scope pixels and output parity |
| Webcam-only OH framer and live loudness overlay; other outputs stay clean | Existing webcam overlay settings and native output branch | Unchanged by this proposal; verify output-specific scope and persisted settings |
| Accurate output/readiness reporting and healthy Program/Preview delivery | Existing native pipeline, measured status and recording state | No redesign may trade quality or cadence for layout; real output/meeting acceptance stays separate |
| Live audio controls, devices, processing and routing | Existing Audio workspace, essential source controls in inspector | No new Apply barrier; behavior/settings must round-trip |
