Reproducibility snapshot v19.0.0 (deposit v2.0.0) for "Navigating the adaptation-maladaptation continuum in infrastructure policy: a per-asset decision-support framework across 39 OECD countries"

Second versioned release (New Version on concept DOI 10.5281/zenodo.21625126) accompanying the v19 P1-CRM manuscript resubmitted to Climate Risk Management (Elsevier) after post-rejection scope refit. Underlying SSI Index v4.23.0 cohort snapshot (39-country × 725,462-substation, frozen 27 July 2026) is UNCHANGED from the v1.0.0 (v8) deposit. This bump reflects a substantive scope refit and manuscript restructure from the pre-investment framing of v8 to a policy-decision framing responsive to Climate Risk Management scope, closing seven audit rounds plus a final touch pass (v8 → v9 initial refit → v10 → v11 → v12 three-contribution restructure → v13 → v14 aggressive compression → v15 → v16 → v17 factual corrections → v18 → v19 final touch). The paper now delivers three distinct contributions: (Contribution 1) a per-asset Reckien-faithful NAM classifier composed with a structural-vulnerability adjunct layer; (Contribution 2) an Italian anchor delivering 5-of-5 rejection at Bonferroni significance under conservative clustering (deff = 10) on five Italian events against ARERA per-event registers (Delibera 566/2019/R/eel TIQE + 646/2015/R/eel + 172/2022/R/eel + Terna logs), extended with a delta-over-hazard-atlas decomposition (Y_mean = +21.46 pp arithmetic, n_j-weighted +18.92; envelope [+18.78, +25.53]) rebuilding an atlas-only classifier from four JRC/Copernicus/INGV-ingesting modifiers (R6c/R6_seismic/R6d/R6e), plus a 15,000-permutation independence check (5 events × 3 conditioning modes × 1,000 draws each) confirming 0/15,000 exceedances — the Italian ARERA-TIQE anchor is SIGNAL not TAUTOLOGY; (Contribution 3) a register-access-prerequisite finding quantified via a Spanish 5-event battery (Filomena 2021 + Andalusia/Extremadura fires 2022 + Tenerife wildfire 2023 + Valencia DANA 2024 + Iberian blackout 2025) yielding 0-of-5 under tight municipal geometry and an Italian per-NUTS-3 cross-scale test collapsing 5-of-5 to 1-of-5, coupled with a CNMC SIETRE power-analysis (23.9–39.0% minimum sensitivity envelope for 5-of-5 rejection at α_adj = 0.01, deff = 10; binding event Tenerife n=322). Round 5.5 factual corrections landed: CERD Article numbers verified via EUR-Lex (Art 9 confidentiality, Art 13 supervision, Art 15 incident notification, Art 19 competent authority), RTE Cardew phantom platform retired, EIA Form 411 restored to Form 861 + Form 860 naming, MITECO CEL / BNetzA §14a / EU Climate Law Art 5 nomenclature corrected, OECD 38-plus-Greenland count anchored per OECD press release, ARERA-TIQE per-substation register-access granularity honestly acknowledged. Supplementary Materials v8 replaces stale v3 with full sections S1 + S2 + S3 + S3a + S5 + S5b + S6 + S7 + S8 aligned to v19 body cross-references.
