Architecture Decision Records (ADRs)

This directory documents significant architectural decisions made during VAPORA development. Each ADR captures the context, decision, rationale, and consequences of important design choices.

ADR Index

#	Title	Status	Date

How to Use ADRs

1. Reading an ADR: Start with the "Decision" section, then read "Rationale" to understand why
2. Proposing Changes: Create a new ADR if changing a key architectural decision
3. Context: ADRs capture decisions at a point in time; understand the phase (MVP, phase 1, etc.)
4. Related Decisions: Check links to understand dependencies between decisions

ADR Format

Each ADR follows this structure:

• Status: Accepted, Proposed, Deprecated, Superseded
• Date: When the decision was made
• Authors: Team or individuals making the decision
• Context: Problem we were trying to solve
• Decision: What we decided to do
• Rationale: Why we made this decision
• Consequences: Positive and negative impacts
• Alternatives Considered: Options we rejected and why
• Migration Path: How to evolve the decision
• References: External documentation
