Enum RenderMode 

pub enum RenderMode {
    Diff,
    Debug,
    ScreenReader,
    NonInteractive,
}

The render mode selector (render_frame’s mode arg).

Each arm sets ONLY fields that already exist on FrameParams and calls FrameWriter::write_frame unchanged — the M3-E scope rule (no new rt logic; rt is covenant-frozen). The screen-reader / non-interactive behavioral branches (SGR stripping, alt-screen, etc.) are M3-K2’s JS-side job; M3-E only wires the existing knobs.

Variants

Diff

Interactive incremental render: debug=false, is_tty=true. Advances the live FrameWriter baseline; emits the line-diff bytes (BSU/ESU-wrapped).

Debug

Plain full-frame render (FrameParams.debug=true, frame.rs:123): no diff, clear, or sync. Routed through a THROWAWAY writer so it consumes NO diff state — a debug render between two live frames cannot corrupt the next diff’s steady-gate or clear decision. renderToString is this mode.

ScreenReader

Screen-reader: a full plain frame, same no-diff-state-consumed property as Debug (routed through the throwaway writer). The accessibility transform of the content is M3-K2’s JS concern; here it is the debug knob.

NonInteractive

Non-interactive (is_tty=false): write_frame’s non-TTY path — no clear, no sync wrap, output padded with a trailing newline and diffed. A real render that advances the live baseline.
