nx_mccabe_gate.nx

nx_mccabe_gate.nx -- teeth for the cyclomatic-complexity census. IN-PROCESS: imports nx_mccabe_lib.nx and calls mc_scan_file directly, so it exercises the SAME code the census runs and has no NOT-DEPLOYED failure mode. EVERY v(G) BELOW WAS COMPUTED BY HAND FIRST AND IS WRITTEN INTO THE TOOTH NAME. A complexity organ that is only checked against itself is unfalsifiable; these are six shapes whose answers are known independently. THE TWO TEETH THAT MATTER MOST ARE THE TRAPS. The trivial wrong implementation is a text search for the keywords, and it passes every counting tooth here -- only the COMMENT trap and the STRING trap refute it. Measured on the real corpus before this organ existed: the first `&&` occurrences a naive search finds are all inside comments. A SCANNER THAT DOES NOT SKIP COMMENTS MEASURES THE DOCUMENTATION, NOT THE CODE. Fixtures are planted at runtime under /tmp/mccabe_gate/ and unlinked before creation, so the gate is idempotent and shares nothing with any production beat. license_tier: ORIGINAL expect_exit: 0
