ADR Lifecycle

1. Proposed

Initial draft for discussion and review

2. Accepted

Approved and implemented in the system

3. Rejected

Considered but not implemented

4. Deprecated

No longer relevant but kept for history

5. Superseded

Replaced by a newer ADR

How to Use ADRs

Creating a New ADR

  1. Copy the comprehensive template or choose another template
  2. Create a new file in the docs/architecture/decisions/ directory
  3. Name it with a sequential number and descriptive title (e.g., adr-0001-use-postgresql.md)
  4. Fill in all relevant sections of the template
  5. Submit for review through the standard process
