## Changelog

### 1.0.0 – 2026-10-18 (not yet published)

- First release: compare 1–100 keywords on one common Google Trends 0–100 scale.
- Anchor chaining with mid-popularity anchor, star screening, refinement ladders and weighted least-squares batch scales.
- Per-keyword precision and consistency metrics; self-check against a direct ≤5-term Google query.
- Geo (country/region/metro), presets and custom date ranges, category, Web/News/YouTube/Images/Shopping.
- Optional related queries and interest by region.
- Dataset (long format) + `OUTPUT`, `results.json`, `results_wide.csv`, `summary.csv` in the key-value store.
- Bounded exponential backoff for 429/5xx/timeouts, session rotation, hard caps on requests and runtime.
- Pay-per-event: `keyword-compared`, `keyword-extra-data`; respects max cost per run; no charge for failed/no-data keywords.
