# Architecture decision records

ADRs capture durable choices that affect more than one package or phase.

- Filenames use a four-digit sequence followed by a short kebab-case title.
- Status is `Proposed`, `Accepted`, `Superseded`, or `Rejected`.
- Accepted ADRs are immutable except for status and cross-reference corrections.
- A changed decision receives a new ADR that links to and supersedes the old one.
