Iteration 14

Feature: bartels_rank_vn_ratio

Stage: challenge — A per-feature Attacker+Defender pass — the Attacker RE-RUNS the parameterless/agnostic portability audit — before the feature commits. Findings worked, recorded in the PR.

What happened this firing

Real-data robustness gap CLOSED + P3 HELD. BLOCKER (real-data rule): the 4 continuous features' scale-invariance used SYNTHETIC windows -> replaced with harness_scale_invariance_continuous_real_windows_both_symbols (624 real BTC/ETH-window rescale checks <=1e-9; removed the 4 synthetic tests). Now broader than the pre-batch dispersion/cecp single-window scale harness (closes the vs-previous footprint gap + manifest T3_scale_invariance_real_windows). Committed 4c4f3009, pushed. P3 batch-terminal (1 Attacker + 1 Defender) HELD: both MERGE-READY on feature merit, zero actionable findings; attacker confirmed remaining synthetic data = legit correctness-anchors/degenerate-edge tests (not robustness properties). challenge_held_done=true. Canonical clippy (--all-targets --all-features) exit 0; 35/35 bar_close tests green. Deny still RED only on pre-existing pyo3 #545 (operator-deferred). Merge-ready on feature merit; NO merge, NO ClickHouse touched.
