Governance
Adjacent publishes the policies and per-ticker documents that govern how its indices are constructed, calculated, and maintained.
What the catalog holds
The catalog holds family-wide policy documents. Each ticker also has a methodology and a factsheet. The methodology is the rule: universe, selection, and weighting. The factsheet describes the index as published.
How governance shows up in the data
Every cycle records which constituents were included, held, or excluded, and why. A methodology change is versioned. It is not applied silently. A published value can be read against the rule then in force.
The methodology overview is the plain-language summary of the same material. Use the overview before a ticker methodology.
