Encoder dual-output: StreamEnabled/RecordEnabled/RecordPath options; per-output ffmpeg block (stream ->flv, record ->mp4); throw unless at least one output. RecordingFile: auto-name ty-<yyyymmdd>-<start hhmm>-0000.mp4, rename-on-stop to ty-...-<len hhmmss>.mp4 with numeric-suffix on collision. LayoutStore persists record folder. MainViewModel: REC/ON-AIR pills, status light, single Start<->End button (replaces Start/Stop variants), StopStream no longer signs out, explicit session timer. About overlay widened. Sign In label + spacing before Start. Tests: 244 passed / 246 (2 pre-existing: AudioPipeline gains-mute, RoundClip). Build 0 warnings. Scope check clean. Memory-map correction (derived-solution rule, 2026-08-29): image-shrink recipe was never recorded when first done, so it was re-derived. Added Derived-solution/recipes rule to AGENTS.md; MyMistakes.md now a permanent recipes registry (records the verified WPF-imaging shrink recipe); schema.md rows MyMistakes as registry; ai.md points to the rule. README hero image replaced: 3.2MB screenshot -> 1400x794 -> 188KB docs/ytLlive-preview.jpg (JPEG q82).
