…lobal-PGM epic (#236) ADR-021 records the epic's constitutional decision: the image tier is the PRIMARY PGM product at scale; horizon steps +1/+6/+12/+24/+36 as PNGs with the hover heatmap at step +1; four summary layers (MAP headline, P(any violence), upper 90%/95% HDI); layer-typed colour (log counts, linear 0-1 probabilities); grey no-data; the interim GAUL crosswalk with its declared handover path (C-211 -> views-datafactory#341 / views-postprocessing#123); the S=1000 memory discipline (C-212). Rejected alternatives and the byte physics (245 MB refused animation) are recorded with measured numbers. CICs re-aligned with shipped behavior: cic_forecast_report_template (streamed ingestion, layer collapse set, step/layer render strategy, updated test alignment) and cic_mapping_module (exactly-one-month image contract, color_mode contract, identity-preserving cast, grey no-data, new failure-mode rows). Method anchors only (C-210). Register: C-211 cross-ref now points at ADR-021. validate_docs.sh green. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…cribing the ladder (#236) The recall review of the governance changeset caught the drift the S6 rewrite itself missed: pgm_raster had become dead config (removed — the step-+1 raster is standard, not an opt-in; docstring + config CIC updated); plot_map now REFUSES raster+image_fallback in one call instead of silently dropping the hover heatmap (+red test); the mapping CIC's untouched bullets no longer describe budget-triggered tier selection ('heatmap stays primary' clause fixed, pgm_lattice_cell_frames import claim corrected, ladder vocabulary retired in both CICs); ADR-018's render-ladder addendum carries an in-place SUPERSEDED-mechanism update pointing at ADR-021 (repo amendment convention); the max_raster_cell_frames docstring states backstop semantics instead of promising a PNG escalation that no longer exists; the register's Cluster C line no longer calls resolved C-209 'reopened'; both CICs' Last reviewed stamps are current; mapping CIC header gains ADR-021. Verified clean by the same review: register arithmetic, every repo-checkable ADR-021 number, all cross-references, C-210 no-line-number policy, and alpha=0.95 confirmed ON the tower's canonical grid (no silent snap — the '95% HDI' label is honest). 402 tests green.
