# Gitea Actions CI/CD - build + deploy SOLUTION_ERP to IIS on same VPS.
# Trigger: push to main, or manual dispatch.
#
# Self-hosted Windows runner on VPS (shared with VIETREPORT). Runner has:
#   - git, .NET 10 SDK, Node 20, IIS
#   - Can deploy locally (no WinRM needed)
#
# Secrets required in Gitea repo settings:
#   - JWT_SECRET     (64+ chars random)
#   - DB_CONNECTION  (full connection string with vrapp password)

# Path filter — skip CI khi commit chỉ docs/MD/skill (~110s saved per docs commit).
# Commit MD-only như "Docs: chốt session" sẽ KHÔNG trigger workflow.
# Lưu ý: nếu cùng 1 commit thay đổi cả MD + code → vẫn trigger (đúng behavior).
