+### Plasma fingerprint workaround
+
+Experimental and unaudited. The `plasma-fingerprint-workaround` package is an
+inert controller for installing a patched Fedora KScreenLocker build that
+recovers fingerprint authentication after suspend. It makes no lock-screen
+changes when installed and must be enabled explicitly:
+
+```bash
+sudo plasma-fingerprint-workaround enable
+```
+
+The patched build is not present in the DNF repository and therefore cannot be
+selected by a normal system update. The controller can also install a locally
+built RPM and restore Fedora's original package. See the tool's
+[`README`](plasma-fingerprint-workaround/README.md) for the security warning,
+build instructions, version checks, and force-downgrade option.
