pub fn select_with_params(
state: &ScoredState,
budget_tokens: Option<u32>,
tau: f64,
no_content: bool,
) -> DiffContextOutputExpand description
Light phase: selection + 3 post-passes + render. Cheap. Re-runnable
against the same ScoredState with different (tau, core_budget_fraction)
to sweep a calibration grid without re-doing the heavy phase.
core_budget_fraction is read at the start via selection().core_budget_fraction
— set the env var DIFFCTX_OP_SELECTION_CORE_BUDGET_FRACTION before
calling to override per-cell.
