-- Windows/MSVC 32-bit candidate10 challenge-drive behavior remains the current
- live-validated Windows authority.
-- Candidate11 compiles cleanly through Linux/CMake as a static binary.
-- Native-report fixtures and schema/semantic validation pass.
-- A portable XDFS/XBE metadata fixture proves title, media ID, Title ID, raw
- GameRegion, formatted region, and UTF-16-to-UTF-8 conversion.
-- Linux ISO/XISO code now returns the same structured Xbox result fields used by
- native reports, summary output, hashes, and Redump verification.
-- Linux GDR-8050L default output names can be derived from XBE/DMI metadata.
+- The maintained Visual Studio 2019 32-bit build and native-report fixtures pass.
+- Linux/CMake builds pass with explicit normal-user `CAP_SYS_RAWIO` handling.
+- A GCC-4244 B101 completed the Sonic Mega Collection (US) GameCube dump with an
+ exact full-image hash match.
+- The exact 0.5.3.16-pf1 Linux executable later completed a controlled
+ GCC-4244 B101 GameCube smoke with all 20 seed blocks, partial output,
+ cancellation, native reporting, profile reporting, and STOP UNIT.
+- The exact 0.5.3.16-pf1 Linux executable completed the modified GDR-8050L
+ `0xE7` GameCube path on physical GDR-8163B hardware cross-flashed with
+ GDR-8050L `0012` firmware. The run completed all 20 seed blocks, partial
+ output, cancellation, native reporting, profile reporting, and internal
+ STOP UNIT.
+- The Linux GDR-8050L path established both Xbox game-view transitions, read
+ XDVDFS metadata, captured DMI media ID `TQ00501A`, produced a controlled
+ partial GAME-XDVDFS output with hashes and native reporting, and completed
+ STOP UNIT.
+- Native `friidump-test-result.v1` reports cover complete, partial, failed,
+ cancelled, no-media, seed-failure, and modified-firmware states.

+## 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.
