+RIP-PoA Hardware Fingerprint Validation — Platform Auto-Detect Wrapper
+======================================================================
+
+Auto-detects the current OS and delegates to the correct platform-specific
+implementation (linux/, windows/, macos/).  This allows running
+
+    python3 miners/fingerprint_checks.py
+
+from the repository root on any supported platform.
+
+The platform-specific files are byte-for-byte identical; the subdirectory
+layout exists for discoverability and to keep each platform miner
+self-contained (each miner lives in its own directory with its own
+fingerprint_checks.py, requirements, etc.).
