KnouandClaude Opus 5 e855d583e3 Document restructuring and the beginnings of Filter 2 changes
Split the pipeline documentation by purpose so each fact has one home:
- docs/pipeline-plan.md keeps the plan, checklist, tracker, and guardrails
- docs/decisions.md holds open decisions and the dated decision log
- docs/reviews/ holds findings and tasks: one file per filter, plus
  00-cross-filter.md for findings that span filters
- scripts/common/README.md holds the shared-helper rules (formerly Phase 2)
- filter-calculations.md now describes calculations only

Filed findings 12-22 from a consistency audit of the app, docs, and scripts.

Filter 1 (Köppen-Geiger): use "Köppen" with the umlaut in all prose, labels,
docstrings, help text, and checker messages (finding 21), and correct the
base build's "majority" docstring (finding 22).

Filter 2 (annual avg temperature): record the adopted definition in
filter-calculations.md §2: equally weighted 1991-2020 monthly normals, per
WMO-No. 1203 and NOAA's 2020 methodology; area-weighted county means; blank
unless all 12 months exist. Code changes for this filter are still pending.

Filter 12: Clear-sky GHI reduction

Status: Not started.

Data key: clearSkyGhiReductionIndex. Calculation: filter-calculations.md §12.

Findings

10. Clear-sky reduction averages ratios rather than energy totals. This is a valid but specific definition. It gives each retained time row equal weight, rather than weighting rows by available clear-sky energy. The label and documentation should retain this distinction.

Cross-filter findings that affect this filter, in 00-cross-filter.md: 11 (inconsistent aggregation) and 16 (the app's NSRDB source link no longer resolves).

Decisions

None yet.

Tasks

Not started; follow the per-filter review checklist in pipeline-plan.md §5.
