nx_ccheck.nx

nx_ccheck.nx -- sovereign COMPILE-CHECK for the WRITING HUB. Operator 2026-07-01: "build into the nishi ecosystem the required functionality." The Nishi shell / nx_sov_build_run can build+run any organ, but a DAEMON (nx_writer_serve) would run+block -- so there was no way to just ASK "does this source compile?". This is that tool: for each target it fork+execs nx_cc_sovereign on runtime/<name>.nx, DUPs the child's stdout to a drained pipe (so the ~125k-line asm never floods), reaps the real EXIT code, and prints CC-OK / CC-FAIL (compiler errors still hit stderr, visible). NO-ARG so nx_sov_build_run drives it directly. license_tier: ORIGINAL module: nishi-core.tools.ccheck
