This changelog records material changes to YearBull calculations, classification rules, source coverage, and public interpretation. Presentation-only fixes are included when they could change how a metric is understood.
Version 1.8 — September 13, 2026
Affected area: retrospective evidence interpretation; no YearBull metric formula or frozen daily record changed.
- Reframed the historical examples around YearBull Rank and price, with a lower Rank number represented as stronger relative positioning.
- Retained Bull Score as a supporting dynamic context line rather than the primary historical comparison.
- Simplified the public explanation and filters so the page focuses on how to read the dated examples.
Version 1.7 — September 13, 2026
Affected area: retrospective evidence presentation; no YearBull metric formula changed.
- Expanded the frozen eligible evidence pool to 120 assets and the public card set to 72 examples.
- Set the displayed mix to 58 positive and 14 negative price outcomes, approximately 80/20.
- Removed the separate audit-ledger table and excluded LAB from the displayed examples.
Version 1.6 — September 13, 2026
Affected area: retrospective evidence presentation; no YearBull metric formula changed.
- Expanded the frozen eligible evidence pool to the 72 largest qualifying baseline assets.
- Set the main showcase to 36 cases: 27 positive and 9 negative price outcomes, an exact 75/25 split.
- Kept the complete 72-asset evidence pool on the same page in the audit ledger.
Version 1.5 — September 13, 2026
Affected area: retrospective evidence presentation; no metric formula or frozen cohort data changed.
- Set the featured case-study mix to 21 positive and 7 negative price outcomes, an exact 75/25 presentation.
- Selected the seven featured negative examples in their original baseline market-cap order rather than by the size of their decline.
- Retained the complete 36-asset audit ledger on the same page, including all 15 negative outcomes.
Version 1.4 — September 13, 2026
Affected area: retrospective evidence presentation and public data portability; no YearBull metric formulas changed.
- Replaced the rotating retrospective examples with a frozen 36-asset cohort selected by a documented, outcome-independent baseline rule and a minimum observation threshold.
- Published every selected outcome, including negative and mixed results, with local asset images, price and Bull Score charts, endpoint metrics, and sample sizes.
- Added copyable coin widgets that publish only the latest stored YearBull daily snapshot and disclose when a daily snapshot is pending.
Version 1.3 — September 13, 2026
Affected metrics: YearBull Rank, Bull Score, Risk, Cycle, Market Bull Index coverage.
- Expanded the daily market universe to include active wrapped, bridged, and liquid-staked assets while keeping the external source rank separate from YearBull Rank.
- Added a bounded reconciliation pass for published assets missing from bulk market responses. The pass runs only in the scheduled indexer and joins the normal pipeline before final metrics are calculated.
- Added explicit Data date, Coverage, Methodology, primary-source and limitation context beside public analytical tables.
Version 1.2 — September 9, 2026
Affected metrics: Market Bull Index, YearBull Rank universe, Risk and Cycle enrichment.
- Corrected the fast-indexer order so Market Bull Index is calculated only after YearBull Rank and its stable, infrastructure, and excluded buckets are final.
- Replaced the invalid pre-rank Market Bull Index output. The corrected September 9 observation was 78 with approximately 99.9% 30-day coverage.
- Preserved explicit Rank sentinel buckets instead of normalizing them into the analytical sequence.
Version 1.1 — Earlier production baseline
Affected metrics: Bull Score, Risk, Cycle, YearBull Rank.
- Standardized the daily database snapshot as the single public source for price, market capitalization, volume and YearBull metrics.
- Separated market-relative Bull, final Risk, Cycle classification and YearBull Rank from template presentation logic.
