Project goals

Create a small, local RSS subscription component that demonstrates specification- driven development with observable evidence.

Scope

• Add a normalized HTTP(S) feed URL.
• List subscriptions in insertion order.
• Reject invalid or duplicate input without partial state.
• Return copies so callers cannot change stored records.

Constraints

• Standard-library implementation for the primary Node exercise.
• No network requests, credentials, real user data, polling or persistence.
• No generated performance/productivity claims.
• One bounded implementation slice at a time.
• Keep acceptance tests unchanged unless a reviewed requirement changes.

Completion

The supplied contract tests pass, an intentionally wrong implementation is rejected, and the learner can trace each requirement to a spec, plan, task and executed check. A UI, if added independently, requires its own accessibility and navigation evidence.
