Decisions are classified into three tiers consistent with the project's own governance model. Tier 1 decisions are day-to-day technical choices made by working groups. Tier 2 decisions are cross-system or architectural choices requiring broad documented consensus. Tier 3 decisions are foundational or governance choices requiring a community-wide process.
This page is updated as decisions are made. The canonical record lives in the GitHub repository under docs/architecture/decisions/ as individual Architecture Decision Records (ADRs). What you see here is the public-facing summary.
