- backend/Dockerfile: run migrations via start.sh before uvicorn instead of launching uvicorn directly (prod was skipping Alembic) - backend/scripts/start.sh: alembic upgrade head + uvicorn exec - documents_proxy.py: add explicit "" route so GET /api/documents (no trailing slash) returns 200 instead of 307 redirect - README.md: update Containers table, volumes section, and Current State to reflect the new 4-container architecture with doc-service Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
