Architecture Decision Records (ADRs)
This directory contains Architecture Decision Records (ADRs) for the Go Platform project.
What are ADRs?
ADRs document important architectural decisions made during the project. They help:
- Track why decisions were made
- Understand the context and constraints
- Review decisions when requirements change
- Onboard new team members
ADR Format
Each ADR follows this structure:
- Status: Proposed | Accepted | Rejected | Superseded
- Context: The situation that led to the decision
- Decision: What was decided
- Consequences: Positive and negative impacts

Adding New ADRs
When making a new architectural decision:
- Create a new file:
XXXX-short-title.md(next sequential number) - Follow the ADR template
- Update this README with the new entry
- Set status to "Proposed" initially
- Update to "Accepted" after review/approval
