Emi Griffith	884df0ade5	narrative: precomputed plain-English day summaries ... Adds /api/v2/narrative, serving a one-sentence summary of how unusual a given day was at a location. Generation is a batch job (scripts/generate_narratives.py) that talks to a local Ollama; the endpoint only ever reads the cache, so no request path depends on the inference host being reachable or powered on. A miss answers 200 with narrative:null and status "pending" rather than 404. The model is handed tier labels and percentile directions only, never a temperature or rainfall figure, so it has nothing to misreport; the sanitizer then rejects any output that carries units, a forecast or advice. Fact lines state direction ("warmer than 82% of nights at this time of year here") because the earlier "82nd percentile (High)" form was read backwards and phrased a warm night as a cool one. Narratives are unit-free as a result, which also keeps one cached row per cell/date instead of a per-country degree variant. Storage is a new `narrative` table in the derived store, LOGGED on Postgres unlike its two UNLOGGED siblings: losing it costs an LLM pass over the whole grid, not a recompute from parquet.	2026-08-02 01:14:37 +00:00

emi	a4fa72639f	Add cheap, stable content-page cache token (#47) ... Content pages keyed cache validity on the full-history hist_end, invalidating ~1-2x/day and paying a 45yr load even to compute the token. Add content_token(cell_id) = PAYLOAD_VER:CONTENT_VER:max_date, backed by an indexed MAX(date) (climate_store.history_max_date / climate.history_max_date), so it survives intra-day top-ups and needs no full-history load.	2026-07-24 19:30:38 +00:00

emi	790b6bf0dc	Migrate off the Open-Meteo weather API (Phases 0-4) ... Steady-state usage of the Open-Meteo API is removed; it remains only as a dormant fallback. Geocoding -> local GeoNames + Nominatim; wind gusts -> Meteostat; history -> NASA POWER (curated cells seeded with keyless ERA5); recent+forecast -> NASA range + MET Norway. Plus a drift-check tool comparing NASA vs Open-Meteo. All keyless, no new infra. Backend suite green in-image (gate).	2026-07-23 14:34:51 +00:00
