nx_ivvbeat.nx

nx_ivvbeat.nx -- the IV+V beat: re-runs the estate's own verification gates and reports DRIFT. WHY THIS EXISTS. The ivvreg- plane holds four rows of desired independent-verification state and, measured 2026-08-07 across buildroot/*.nx (51,707 files), _offc/*.sh (12,433) and knowledge/registry (297) -- every scan marker-confirmed coverage_complete=1 -- NOTHING HAS EVER READ IT. The consumer was specified in data and never built. So this is not a port of anything; the plane IS the spec. (STAR)A DATA PLANE WITH NO CONSUMER IS A SPECIFICATION NOBODY IMPLEMENTED -- IT LOOKS LIKE STATE AND BEHAVES LIKE A TODO. The rows even include a purpose-built negative control, so whoever wrote them knew exactly what the beat had to do. WHAT IT ANSWERS: "do the estate's own gates still pass?" That is the same hole board item 7 named for published surfaces -- nothing was checking -- one level down: nothing checks the CHECKERS. SAFETY. Every exec and every delete is decided by nx_ivvguard, whose predicates are proven 23/23 by nx_ivvguard_gate INCLUDING all four live rows. That gate previously passed 12/12 while the predicate was WRONG, because every fixture in it was fabricated; the four real rows were what exposed it. THE WIPE IS DELIBERATELY NOT IMPLEMENTED IN v1, and each row says so out loud. The wipe column asks for a prefix-glob delete; the verification value -- do the gates still pass -- is fully available without it. (STAR)WHEN THE RISKY HALF OF A CAPABILITY IS NOT REQUIRED FOR ITS VALUE, SHIP THE OTHER HALF FIRST AND MEASURE WHETHER THE RISKY HALF WAS EVER NEEDED. If gates pass unwiped, the delete is unnecessary; if they fail, that is evidence the wipe is load-bearing, and its predicates are already proven and waiting. A row whose wipe spec is UNSAFE is refused outright rather than run dirty -- the author asked for cleaning this beat will not do, so its result would not mean what the row intended. v1 IS REPORT-ONLY BY CONSTRUCTION: it files no debt. A detector's first live run must be readable before it is allowed to write, or its own defects arrive as a pile of authored records. license_tier: ORIGINAL No hw writes (Rule 26). Deletes nothing.
