Plan: Team Velocity Dashboard

Context

We're building a dashboard for engineering managers to track team code velocity — commits per engineer, PR cycle time, review latency, CI pass rate. The data already lives in GitHub; we're just aggregating it for a manager's single-pane view.

Changes

1. New React component TeamVelocityDashboard in src/dashboard/
2. REST API endpoint GET /api/team/velocity?days=30 returning aggregated metrics
3. Background job pulling GitHub data every 15 minutes into Postgres
4. Simple filter UI: team, date range, metric

Architecture

• Frontend: React + shadcn/ui
• Backend: Express + PostgreSQL
• Data source: GitHub REST API (cached 15min)

Open questions

• Should we support multiple repos per team?
• Do we show individual engineer names or aggregate only?
