KnouandClaude Opus 5 867a07cecb Refine project documentation and track metric files
Close gaps found in a review of the documentation:
- Track data/metrics/ and data/metric_sources.json in git so the data
  checker passes on a fresh clone (finding 23; decision logged)
- State the Alaska and Hawaii coverage gap in the README limitations and
  extend finding 12
- File findings 24-26: the data-sources doc lacks gridMET and several
  pipeline commands; wettest/driest month are computed twice; solar GHI
  is written by the extreme-temperature apply step
- Add the stale "fallback values" note to filter 2's tasks

Tidy the document system:
- Add docs/reviews/README.md with the numbering rules and a finding index
- Rename koppen-mixed-display-plan.md to koppen-mixed-display.md and fix
  its stale Puerto Rico and "stage 5" text
- Add the precipitation-month step to the README enrichment list
- Describe the Current method / Previous method pattern in plan section 5
- Add CLAUDE.md with the project guardrails and doc layout

Format filter-calculations.md so it renders on GitHub and in VS Code:
inline math uses $...$, ranges use en dashes, and implementation
references name functions instead of line numbers.

# Project notes for Claude
US County Climate Explorer: a static Leaflet app (`index.html`, `app.js`,
`styles.css`) over `data/climate-data.csv`, built by the Python scripts in
`scripts/`. The 12 filters are being reviewed one at a time before the CSV is
restructured; see [docs/pipeline-plan.md](docs/pipeline-plan.md).
## Guardrails
- Never rerun `scripts/build_county_climate_data.py` over
`data/climate-data.csv`. It drops live columns and overwrites `koppenZone`
(pipeline plan §7).
- Change one filter at a time. After every apply step, run the checker and
compare changed counties against expectations.
- Run scripts from the project root with the virtual environment:
- `.venv\Scripts\python.exe scripts\check_climate_data.py`
- `.venv\Scripts\python.exe -m unittest discover -s tests`
- When `app.js` or the data files change, bump `APP_ASSET_VERSION` in `app.js`
(it also versions the CSV and GeoJSON URLs) and the matching `app.js?v=`
query in `index.html`. `styles.css` has its own query in `index.html`.
- The map and every filter cover the 50 states and DC. Puerto Rico rows stay in
the data files but are never shown.
- Do not start the Phase 3 CSV restructure until all 12 filters are reviewed.
## Writing
- Write "Köppen" with the umlaut in prose, UI text, help text, and messages.
Use ASCII `koppen` only in identifiers, file names, and data paths.
## Documentation layout
Each fact has one home:
- `docs/pipeline-plan.md`: current pipeline, target design, phases, the
per-filter checklist (§5), the filter tracker (§6), and guardrails (§7).
Keep it about 200 lines.
- `docs/reviews/`: one file per filter with its findings, decision links, and
tasks; `00-cross-filter.md` for findings that affect several filters.
`docs/reviews/README.md` has the numbering conventions and the finding index.
- `docs/decisions.md`: open decisions and a dated log of decided ones. An item
leaves "Open decisions" only when the project owner decides it.
- `docs/filter-calculations.md`: what each calculation is. No review status.
- `scripts/common/README.md`: rules for shared helpers.
Keep the tracker status in the plan and the review-file checkboxes in sync.
