Module xo 

Crossover recommendation from immutable designs and measured responses.

Upstream: calibration.xo_groups, xo_scores, pick_xo, recommend_xo.

Structs

XoRecommendation

Ordered crossover comparison and the best candidate for each group.

XoRow

One candidate’s metrics and combined score.

XoScores

Group-averaged crossover quality before the candidate-relative penalty.

Constants

XO_CANDIDATES

Default crossover candidates in Hz, in upstream order.

Functions

pick_xo

Writes candidate-relative scores, selecting the lower Hz on exact ties. Empty groups are omitted from the returned winners.

recommend_xo

Designs independent XO candidates on the context’s ordered map, then scores them. Progress counts finished candidates, not their internal design stages. Cancellation is shared with every production fitter; no process pool is created.

xo_groups

Main groups in configuration order, or no groups when there are no subs.

xo_scores

Replays the final chain through 500 ms and 2 s measurement windows.
