# syntax=docker/dockerfile:1
#
# Bulk ATS scoring engine — the standalone FastAPI service (CLAUDE.md is its spec).
# Serves POST /api/v1/score, GET /api/v1/health and the card-grid test UI at /.
#
# The backend imports this same package as a library; this image is the separate
# service form of it, so it can be scaled, restarted or pointed at a different model
# independently of the portal API.
#
# THE BUILD CONTEXT IS THE REPO ROOT (pyproject.toml lives there):
#
#     docker build -f app/Dockerfile -t hrms-ats-engine:local .
