2.x ADRs

Architectural Decision Records for the 2.x track. Not the current track — see docs/adr/3.x/ for current decisions.

Naming

  • YYYY-MM-DD-N-descriptive-title-with-dashes.md

Source of Truth

This folder is canonical for 2.x decisions (dates before 2026-03-30, the 3.0.0 release). ADRs dated on or after 2026-03-30 were moved to docs/adr/3.x/. The architecture/ tree was removed by the Common Docs structural move (PR #2225); existing references using the old architecture/2.x/adr/<filename> or architecture/adrs/ paths will need updating to the new docs/adr/ paths.

Status Conventions

  • Accepted means the decision remains current policy.
  • Superseded means a newer ADR replaced the decision; keep the file for history, but do not implement from it.
  • Deprecated means the direction is in active retirement and should not receive new work.
