about

nx_overnight.nx -- UNSUPERVISED overnight runner: the team mines a large search space in chunks, beat after beat, banking what it finds and JOURNALING every beat to a log the operator + Claude review in the morning. Resource-bounded (a parallel pool of K workers, each a fork whose RAM is reclaimed on exit) so it runs all night without growing. Each beat also EXEC-VERIFIES a sample, so any correctness regression is logged as an ISSUE to address. The operator kicks it off (background it / loop the binary); Claude reads the journal next day to critique + build the team up. license_tier: ORIGINAL
