This release tags the v0.3 Cornerstone U.S. model (2024 IO and GHG). Updates made in bedrock to generate that model and prepare for new features are described below. Snapshot SHA: c60bdf4308cb660eee80a246214901cff9122820 GCS prefix: gs://cornerstone-default/snapshots/c60bdf4308cb660eee80a246214901cff9122820/ Canonical config: 2025_usa_cornerstone_v0_3 What's Changed Core pipeline & configuration Canonical pipeline defaults to 2025_usa_cornerstone_v0_3 (2024 IO+GHG, using UMD GHGIA 2024 inventory). Prior release stack preserved as 2025_usa_cornerstone_v0_2 for historical comparison. Snapshot baseline bumped to c60bdf4… (v0.3.0); alpha/beta snapshot SHAs registered in releases.py and USAConfig. Industry output x: expand_industry_output_vector sums many-to-one BEA parents (government-enterprise dollars into electric power 221100 and transit 485000), correcting inflated D/N where E carried those tons under a first-parent-only expand. A-matrix: CEDA fallback scaling with summary A/q dollar-year adjustment (scale_a_matrix_with_ceda_method_as_fallback, adjust_summary_A_and_q_dollar_year); industry price-index A path removed. Inflation: consolidated helpers; single apply_inflation_to_V flag; V-norm commodity price index path; cornerstone industry PI gated behind update_inflation_factors. B matrix: deflate_x_to_detail_io_year_for_B replaces use_useeio_B; y_nab derived from Adom and scaled_q. USEEIO baseline config stack (m2 GHG FBS, before-redefinition use tables, B adjustment) for diagnostics comparison. GHG emissions UMD GHGIA 2024 path (GHG_national_Cornerstone_2024) with revised UMD model wiring. Cornerstone GHG FBS snapshots extended (2017–2018, 2019–2022, 2024); FBS regen pinned in CI (cornerstone_ghg_fbs_2024_pin.json). MECS allocation update; ghgi_mecs method naming fix. Flow mapping files stored in-repo. Electricity disaggregation preparation Electricity reallocation implemented end-to-end to support disaggregation. eGRID plant-level generation, loss, and GHG data; EIA Electric Power Annual FBA to support ongoing electricity disaggregation work. Waste-disaggregation matrix export for electricity inputs; disaggregation module rename (phase 1–2) and cornerstone_disagg_pipeline refactor. EEIO validation & IOT q derivation updates and reference comparisons; 2017 margins-after-redef loaders; default cornerstone_industry_avg_margins. USEEIOR industry CPI when useeio_margins. Publish & exports Phi purchaser-price adjustment in publish path; Phi year panel and dollar-year SEF alignment. USEEIO-style Excel writer scaffolding (expanded matrix coverage). Supply-chain style CSV export. Diagnostics & analysis A-matrix time series workflow (steps 2.5–7): cell stability, cross-approach hexbins, impact-weighted sector deep dive, BEA observed A errors, EF diagnostics compile/plot/dispatch, N stability across methods, YoY ECDF panels, scenario-aware EF plots. EF diagnostics overlay and multi-panel histogram plotters; dispatch + plot Cursor skills. v0.3 release EF diagnostics tooling: sheet registry, combine_ef_diagnostics combos (v0.2_to_v0.3_ceda / v0.2_to_v0.3_useeio), progression / overlay / BLy plotters, optional compare-to FINAL v0.2. Wholesale v0→v0.3 waterfall group diagnostics (v03_waterfall_*): USEEIO stack (G1 schema/GHG → G2 methods → G3 data → FINAL) and CEDA stack (G1a schema/GHG → G1b waste disagg → G2–FINAL); combine combos, dispatch, and cumulative-plus-sequential plot panels with key-sector N overlays. Waterfall Drive sheet IDs pinned to post–industry-x redispatches. Diagnostics merge cleanup with USEEIO baseline comparison options; inflation on USEEIO diagnostic path; real vs summary derived q plots. Snapshot release workflow documented in bedrock/utils/snapshots/README.md. Infrastructure GCS loader skips download when local file exists; snapshot upload path aligned with loader. derive_cornerstone_E removed; build_model_manual_check script for A/q/B from chosen config. Google Drive create_spreadsheet_in_folder helper; estimate_suppressed refactor.
