H4 deployment-scale headline walked back pending a stricter window-causal re-audit on the cluster-nerve construction itself. The previous +0.96-Sortino-over-Hierarchical-Risk-Parity corpus figure (reported on 2026-05-12 from the full-corpus re-scope) is provisional and will be restated, or retracted if it doesn't hold, when the re-run lands. The H20 portfolio-coverage-health monitor and the failure-mode-diversity portfolio constraint sat on the same cluster-nerve substrate as H4, so their FAIL verdicts are part of the same re-audit and are also held provisional. Everything else on the page (H17 PASS, H14 MARGINAL, H3 FAIL, H1 PASS, H2 falsified, and the H5/H10–H19 verdicts) is leak-free by construction and stands as reported.

What this version was

• ▪H4 deployment-scale verdict moved from PASS-with-caveat to UNDER RE-AUDIT. The earlier lookahead-feature retirement had left the H4 selector's lens itself prefix-causal, but the cohort-level cluster-nerve construction used a static cohort-wide configuration that didn't restrict to prefix windows, a residual non-strictly-causal surface. A sampling-class result should be tested under the stricter discipline before its corpus headline number is reported as a verdict, so the deployment-scale figures (≈ +0.96 ΔSortino over hierarchical risk parity, Holm-significant, ≈ 61% of cells won, plus the deepest-drawdowns and the moving-average-zero pattern) are provisional and will be restated when the re-run lands. The corresponding figures (the bake-off bars, the equity curves, the deployment-stack decision-flow) are kept on the page but explicitly tagged as the provisional first-pass renderings.
• ▪H20 portfolio-coverage-health early-warning and the failure-mode-diversity portfolio constraint moved from FAIL to UNDER RE-AUDIT. Both were tested on the same cohort-level cluster-nerve substrate as H4, so their FAIL verdicts are part of the same re-audit and are provisional pending the re-run. Failure-mode labels themselves are leak-free by construction (they sit on the drawdown-shape / robustness-ratio / regime-spread / trade-microstructure fingerprint columns, not on any target regression).
• ▪The four-layer prediction-vs-decision-partition section softened the "three for three" coincident-to-lagging line to two clean cases (per-strategy drift H19; per-window aggregation-risk score) plus one under-audit case (H20). Everything else in the partition copy stands as reported.
• ▪EN + pt-BR. Dek, roadmap caption, scorecard cards, Phase 06 detail, findings cards (H4, H20, failure-mode-diversity, the four-layer partition, the bake-off-bars figure caption, the equity-curves figure caption), the deployment-stack decision-flow figure caption, and the in-page "what changed in this update" lead all updated to lead with the 2026-05-13 walk-back. The 2026-05-12 entries (the H4 full-corpus re-scope, the H20 / failure-mode-diversity findings additions, the codebase refresh, the scorecard rework) are preserved as historical record beneath the new entry.
• ▪Last-updated label bumped to 2026-05-13. The prior live entry, the scorecard / percentage-complete rework, is archived as v10-2026-05-12-scorecard-rework (resolved by the dynamic archive route).
