Architecture decision records

An ADR records a decision that constrains future work: the context that forced it, the choice made, and the consequences accepted. They are immutable once accepted — a reversal is a new record that supersedes the old one, not an edit.

Records here describe decisions that are already embodied in the code. Where a decision is still open, it is on the roadmap instead.

Use _template.md for new records.
