- program_research.py: ttp-crawler integration, Groq Llama 3.3 70B extraction, known sources map, validation
- crawl_scheduler.py: priority queue with off-peak/weekend scheduling
- catalog.py router: research, catalog browse, adopt, schedule, complete, progress endpoints
- Points: 75pts/workout, 50pts weekly bonus, 200pts completion bonus
- config.py: added groq_api_key setting
- main.py: catalog router, background scheduler, v2 migration

Frontend:
- ProgramSearch.jsx: search, research submission, catalog browsing, adopt programs
- ProgramDetail.jsx: schedule view, today's workout, completion modal, progress tracking
- App.jsx: Programs nav tab, new routes
