[NTG-context] precedence of texmf trees

Hi wizards, if I have files with the same name in several texmf trees (e.g. texmf-context, texmf-local, texmf-project, ~/texmf or TeX Live’s texmf-dist, texmf-var), which one will be used? I guess “local” trees or “local” directories take precedence over “distribution”, but which is “the localest” of ~/texmf/..., texmf-dist/.../local, texmf-local/... ? Where is the order defined? (Not in TDS.) Hraban
