+# OPC DA Diagnozer — production dependencies.
+#
+# Install:  pip install -r requirements.txt
+# The interpreter MUST be 32-bit (SPECIFICATION §11): the OPC DA Automation
+# Wrapper and Graybox DLLs are 32-bit in-proc COM servers — a 64-bit process
+# cannot load them. Create the venv with the 32-bit Python (README
+# "Development setup").
+#
+# Note: pyproject.toml remains the canonical dependency source for the
+# package install (`pip install -e .`); this file mirrors it for tooling
+# that expects plain requirements files (pip install -r, constraint sync).
+
+ruamel.yaml>=0.18
+# YAML config loading (config.py). Pure Python — PyYAML publishes no win32
+# (32-bit) wheels for CPython 3.14 and its sdist requires MSVC, which the
+# diag hosts lack.
+
+pywin32>=306; sys_platform == "win32"
+# COM access (pythoncom, win32com, win32evtlog) for the Automation Wrapper
+# adapter, discovery and the Windows Event Log reporter. Every import is
+# guarded so tests still run on any OS (IMPLEMENTATION_PLAN §9).
