pub const CANONICAL_KEY_MIN_WIDTH: usize = 8;Expand description
2026-09-25: Batch width (sequences) at or above which canonical_assignment
selects the canonical arm, unless METRALE_CANONICAL_KEY_MIN_WIDTH overrides
it. Above the scheduler’s D-Cut width cap (SchedLevers::dcut_width_cap),
mtp_dcut::plan leaves every depth equal, and then both arms give the same
order (uniform_depths_are_identical_under_both_arms).
