Architecture Decision Records (ADRs) document the significant choices made during the design and evolution of the Movie Finder system. Each record captures the context, the decision, and the consequences so that future contributors understand why the system is built the way it is.

When to write an ADR¶

Write an ADR for any decision that a future contributor would ask "why did they do it this way?" about. Specifically:

• Adopting or removing an external dependency or cloud service
• Changing the tech stack at any layer (language, framework, database, vector store)
• Introducing a new design pattern project-wide
• Any auth or security model change
• Significant API contract decisions (new endpoint shape, breaking change)
• Infrastructure or deployment topology changes
• Anything debated in a PR where the outcome was non-obvious

If you are unsure, write the ADR as Proposed and let the review discussion determine whether it warrants a record.
