Implements Step 3.3: Animal Cohort Creation - Add AnimalRegistryProjection for animal_registry and live_animals_by_location - Add EventAnimalsProjection for event_animals link table - Add IntervalProjection for location and attribute intervals - Add AnimalService with create_cohort() for coordinating event + projections - Add seeded_db fixture to conftest.py - Update projections/__init__.py with new exports All operations atomic within single transaction. Includes validation for location (exists, active) and species (exists, active). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
