Summary

• First downstream consumer of the climate-departure 3-split lit reviews (Snowpack-departure methodology lit review: Zotero + ragnar + cited vignette #53/Lit-review temperature-departure methodology + interpretation backing #58/Lit-review precipitation + drying methodology + interpretation backing (2/3) #61/Lit-review interpretation framing methodology + reporting backing (3/3) #63). Wires up the kootenay-lake vignette's non-snow interpretation paragraphs with 8 new BBT-keyed citations + 1 reuse, sparingly applied per the feedback_vignette_citations_sparse.md philosophy memory ("library not prescription; cite only authorities for findings visible in the AOI's graphs/tables, plain language, no decoration").
• 7 insertions across 6 sections of vignettes/kootenay-lake.Rmd:
  1. Trends (L184) — @hansen_etal2012Perceptionclimate for the 1951–1980 base period (Hansen 2012 explicitly uses the same window for its 3-sigma loaded-dice analysis)
  2. Trends (L195) — @arguez_vose2011DefinitionStandard for the WMO climate-normal definition
  3. Daytime/Overnight (L246) — @karl_etal1993NewPerspective for the DTR asymmetry "textbook fingerprint" (was prose-style, now proper cite)
  4. Spatial Pattern (L584) — @pepin_etal2015Elevationdependentwarming + @rangwala_miller2012Climatechange for elevation-dependent warming + heterogeneity caveat
  5. Interpretation/drying (L984) — @ficklin_novick2017Historicprojected for VPD continental-scale drying
  6. Interpretation/salmonids (L1014) — @mantua_etal2010Climatechange + @eaton_scheller1996Effectsclimate for the climate→stream-temp→fish thermal-habitat bridge
  7. Interpretation/Fraser (L1027) — @kang_etal2016ImpactsRapidly (was prose-style, now proper cite)
• Audit log at planning/active/citation_audit.md — one row per insertion with vignette excerpt, source quote, rag store + topic where the quote was retrieved, paraphrase as written, and why warranted (the "what is where by who said what where" trail).
• Independent review agent (Explore subagent) verified each row against the source quote archives + PDFs. All 7 passed. One minor scope concern flagged on Ficklin & Novick (vignette said "western US" but paper covers continental US with western/southern concentration in results) — fixed inline before commit.
• vignettes/references.bib regenerated via rbbt::bbt_update_bib() — now has 18 entries (was 11): 8 new, 1 reuse, 9 kept from Snowpack-departure methodology lit review: rag-build + 11 papers + citation map #54, 1 dropped (munoz-sabater_etal2021 wasn't actually cited here).

Snowpack-section citations from #54 untouched (already wired up). 3 FWCP Peace cross-references at L528, L973, L996 not touched on this branch — flagged in progress.md as a separate follow-up worth filing per feedback_thorough_cross_reference_removal.md memory (vignettes are stand-alone).

Relates to NewGraphEnvironment/sred-2025-2026#23.

Fixes #65.

Test plan

• devtools::test() clean (verified: 166 PASS, 0 FAIL — vignette-only changes don't affect tests)
• All 18 [@key] markers in the vignette resolve to entries in vignettes/references.bib (verified via rbbt::bbt_detect_citations round-trip)
• CI pkgdown render builds cleanly without "citation key not found" warnings
• Agent-verified scientific integrity: no hallucinated source quotes, paraphrases faithful, all cites load-bearing
• No vignette section restructuring; only [@key] additions + minor prose smoothing
