Architecture Decision Records (ADR) — Guide
What is an ADR?
An ADR is a short document that captures a significant architectural decision, along with the context and consequences. ADRs create a decision log so future contributors understand why the codebase looks the way it does.
When to Write an ADR
Write an ADR when:
- Choosing or replacing a framework, library, or tool
- Changing the architecture (new layer, new pattern, new boundary)
- Making a trade-off that future developers might question
- Deciding NOT to do something (these are often the most valuable)
Do NOT write an ADR for:
- Implementation details that are obvious from the code
- Formatting or style choices (those go in coding-standards.md)
- Bug fixes or minor refactors
How to Write an ADR
- Copy
adr-template.mdtodocs/architecture/adrs/ADR-NNN-short-title.md - Number sequentially (ADR-001, ADR-002, ...)
- Fill in all sections — especially Context (the why) and Alternatives Considered
- Set status to
Proposed - Open a PR for team review
- Once merged, update status to
Accepted
Existing Decisions (captured retroactively)
These decisions were made before the ADR process was introduced. They are documented here for context:
| Decision | Rationale | Date |
|---|---|---|
| Clean Architecture (hexagonal) for backend | Decouple domain from framework — enable converter swapping (local/remote) | 2025-01 |
| FastAPI over Django | Async-first, lightweight, Pydantic-native — better fit for a single-purpose API | 2025-01 |
| Vue 3 + Pinia over React | Composition API + built-in reactivity — smaller bundle for this use case | 2025-01 |
| SQLite over PostgreSQL | Single-file DB, zero ops — appropriate for a document processing tool | 2025-01 |
| Karate over Playwright for e2e | Team expertise, unified API+UI testing, JVM ecosystem | 2026-03 |
Feature flags via /api/health |
No external service needed — backend capabilities drive frontend UI | 2026-03 |
Lifecycle
Proposed → Accepted → [Deprecated | Superseded by ADR-NNN]
- Deprecated: The decision is no longer relevant (feature removed, context changed)
- Superseded: A newer ADR replaces this one (link to the new ADR)
- Never delete an ADR — mark it as deprecated/superseded instead
