ADR (Architecture Decision Record)

# ADR-001: Use Repository Pattern for Data Access

## Status
Accepted

## Context
Our application needs consistent data access patterns.
Current code mixes direct SQL with ORM.

Handling Difficult Conversations

When delivering bad news:
1. State the facts clearly
2. Explain impact
3. Present mitigation plan
4. Ask for input/support

Example:
"We discovered that the migration will take 2 weeks longer than planned. 
 This delays launch by 2 weeks. We can mitigate by parallelizing testing. 
 I need approval for additional QA resources."
