+## Linux exact-release hardware closure
+
+The two required Linux GameCube hardware targets are complete.
+
+The GCC-4244 B101 exact-release evidence archive has SHA-256
+`7c9573d7dddf6381d8847626d0a45e96e57f2b64d79967a041d8acf4affebef5`.
+The cross-flashed GDR-8163B/GDR-8050L `0012` evidence archive has SHA-256
+`872b8144b8cc55601b268867ad8cc74cc7266a514cf015e24cd2fe3a450ee602`.
+
+The validated cross-flashed unit required a readable Video DVD at power-on
+before it identified as GDR-8050L `0012`. The drive remained powered and
+connected while the disc was changed to Sonic Mega Collection (US). A
+temporary host-probe quarantine prevented background Linux media discovery
+from blocking the USB/SCSI path. The host state was restored after the run.
