Iteration 52 — Anchor Triad M3 CLEAR ALL THREE SURVIVE · PARAMETRIC ≠ KERNEL · M4/M5′ NEXT

In plain words: the three econometric guards passed the field test together — and the most valuable result is the fight we named in advance. The honesty-checker (J) does the same JOB as a guard we already certified (HSIC-X, the kernel-based anchor-validity meter), so the danger was that it would turn out to be the same instrument in different clothes. It is not: across 130 features their readings agree less than half the time (48%) — the classical moment-based check and the modern kernel check genuinely see different failure surfaces, which means having both makes the shelf STRONGER, not redundant. The three guards resemble each other moderately (72–87% — same mathematical family) but all below our same-instrument bar, and the strength-meter's readings spread across the whole range, settling last iteration's open question about whether it can discriminate at all. All three march to the final statistical hurdles as a unit.
