# killinchu STAGING HF Docker Space (Yachay / Perplexity Computer Agent, 2026-06-01).
# Pulls from the SAME SOURCE as prod: clones the prod HF Space repo at build time,
# mirrors its files into /app so prod serve.py's ABSOLUTE /app/* paths resolve
# identically to prod, then runs serve_staging.py with SZL_ENV=staging.
# Reachable at https://szlholdings-killinchu-staging.hf.space
# /api/killinchu/healthz reports env: "staging".
