Enum BindingConstraint 

pub enum BindingConstraint {
    FrameCap,
    ContextCeiling,
    TextHeuristic,
}

Which limit determined the predicted frame count.

Reported because the two have different remedies: a caller hitting the frame cap should raise it or chunk the text, while one hitting the context ceiling must shorten the prompt.

Variants

FrameCap

max_new_tokens bound the generation. The usual case.

ContextCeiling

The context ceiling bound it — the prompt is long enough to crowd out generation.

TextHeuristic

The text-derived EOS backstop bound it (prompt_tokens * 4 + 64 frames).

The sampled EOS is a stochastic stop (README: “EOS stop timing is sampling-dependent”), so a bare ftts say without FTTS_MAX_FRAMES needs a cap proportional to the text rather than the flat 8,192-frame (≈11 minute) policy default. Setting FTTS_MAX_FRAMES disables this backstop: an explicit cap is obeyed exactly.
