+* Temperature-departure methodology literature review (1/3 of the climate-departure 3-split; precip+drying and interpretation framing follow as separate issues). Adds `scripts/rag_temp_methodology_build.R` and `scripts/rag_temp_methodology_query.R`, builds a local ragnar DuckDB from 10 peer-reviewed papers (now in the `NewGraphEnvironment/climate` Zotero collection), and ships the methodology synthesis + 18-row "cite this for that" citation map at `planning/archive/2026-05-issue-58-temperature-lit-review/findings.md`. Coverage spans DTR asymmetry methodology ([Karl et al. 1993](https://doi.org/10.1175/1520-0477(1993)074%3C1007:ANPORG%3E2.0.CO;2), [Easterling et al. 1997](https://doi.org/10.1126/science.277.5324.364), [Vose et al. 2005](https://doi.org/10.1029/2005GL024379)), Canadian/BC temperature trends ([Vincent et al. 2018](https://doi.org/10.1080/07055900.2018.1514579)), elevation-dependent warming ([Pepin et al. 2015](https://doi.org/10.1038/nclimate2563), [Rangwala & Miller 2012](https://doi.org/10.1007/s10584-012-0419-3)), BC downscaling ([Wang et al. 2012](https://doi.org/10.1175/JAMC-D-11-043.1)), the climate-fish thermal-stress bridge ([Mantua et al. 2010](https://doi.org/10.1007/s10584-010-9845-2)), and salmonid thermal envelope ([Eaton & Scheller 1996](https://doi.org/10.4319/lo.1996.41.5.1109), [Richter & Kolmes 2005](https://doi.org/10.1080/10641260590885861)). Headline finding: `cd_trend()`'s raw Mann-Kendall + Theil-Sen aligns with Vincent et al. 2018's Canadian-temperature-trend methodology (Sen slope + Kendall's τ); raw MK is the right call for our 76-year strong-trend series per [Yue & Wang 2002](https://doi.org/10.1029/2001WR000861) (cross-rag from snow methodology store). Also renames existing `rag_build_*.R` / `rag_query_*.R` scripts to `rag_*_build.R` / `rag_*_query.R` (`noun_verb` per cd convention). ([#60](https://github.com/NewGraphEnvironment/cd/pull/60))

 # cd 0.2.1 (2026-05-04)
 
 * Adds a new `kootenay-lake` vignette covering the southern Kootenays — KOTL + LARL + DUNC + SLOC, ~24,200 km². Reads stand-alone alongside `peace-fwcp` and uses the v0.2.0 snow variables to tell a snow-pack story for a region with a sharp east-west precipitation gradient (Selkirks vs Purcells). Headline regional findings (2015-2025 vs 1951-1980): annual SWE -23%, annual snowfall -15%, freshet shift -12.6 days earlier, annual precipitation -7% (p = 0.02). Total annual snowfall is dropping, not just melt timing shifting — consistent with [Knowles et al. 2006](https://doi.org/10.1175/JCLI3850.1)'s threshold finding that significant snowfall-fraction declines occur where winter wet-day Tmin > -5 °C. Adds a per-watershed-group facet view and `data-raw/qa_snow_validation_kootenay_lake.R` ASWS cross-check (5 sites, 74 paired station-years, pooled r = 0.90, mean bias -54%, bias-stable). New bundled assets: `inst/extdata/example_aoi_kootenay_lake.gpkg`, `inst/extdata/context_kootenay_lake.gpkg`, `inst/vignette-data/kootenay_lake.rds`.
