Conductor/Agent mirror the Rust eDSL 1:1 (hire, work/ask/review/revise, freeze, verify, judge, apply, step/scope/patched, gate, preflight, trace); custom verdict policies are plain Python callables committed through judge_begin/commit; on_turn= lets a score (or a test) play the launcher. Typed frozen dataclasses carry the server's raw payloads back verbatim for forward compatibility; errors map to a typed exception hierarchy raised in the score's own stack frame. The patterns layer (ensemble/integrate/pipeline/arena/map_reduce/judge_panel/debate) is ported to public Python, port-faithful including the approval heuristic, the independence expectations and the mean-score tie-break.
