+### RESULT 52 (2026-07-19): 42M 3x3 MATRIX COMPLETE — cent's "zero-gap" was LUCKY-SEED;
+estimator choice does NOT move final CE. cent seeds: 1.2334(s1)/1.2716/1.2579 mean 1.2543.
+Full table: BP 1.2141 | ride 1.2449 | cent 1.2543 | plain 1.2558 — the three EP recipes are
+statistically indistinguishable (means within 0.011, seed spread +-0.02-0.04); RESULT 46's
+cent<ride<plain ladder COLLAPSES (was built on cent n=1 = its lucky s1). The flagship
+"stage1b_cent 1.2334 vs BP 1.2311 zero-gap-class" claim = lucky-s1 vs unlucky-s1, the third
+bite of the dip-statistics lesson, this time on OUR claim. HONEST 42M STATEMENT: EP-vs-BP
+gap = +0.03-0.04 regardless of estimator — consistent with the three 72M endgame estimator
+ties. cent's 72M value is UNTOUCHED (corridor stability is a trajectory property, orthogonal
+to final CE). Deck/report zero-gap lines must be softened accordingly.

 ### RESULT 51 (2026-07-19): CODEX AUDIT — the fw72m_simple collapse was a LEGALITY-GATE CODE
 DEFECT (user's "it's a bug" verdict CORRECT); my AIMD-equilibrium theory demoted to amplifier.
 Independent codex audit + 4-arm replay adjudication. THE HOLE: _legal's res/rho clause used
