unilab.utils.sim2sim.resolve_sim2sim_config

unilab.utils.sim2sim.resolve_sim2sim_config(source_run_dir, target_cfg, *, algo_name=None, strict=True)[source]

Validate a target play config against the source training contract.

Returns None if source_run_dir is None (an explicit “no source run” play); otherwise returns target_cfg unchanged (never mutated). Raises CrossBackendIncompatibleError under strict when any DENYLIST field differs, including asymmetric presence for ENV_STRUCTURAL_DENYLIST paths. A source run whose contract snapshot is missing, malformed, or uses keys outside the current schema fails closed with the same error regardless of strict.
