+# Original PSX browser-play fixture
+
+This fixture is original Ludarium test code. It initializes the PlayStation display to a
+solid blue background and waits for vertical blank forever. It contains no Sony BIOS,
+license sector, SDK binary, retail executable or game asset.
+
+Build provenance:
+
+- PSn00bSDK `v0.24`, commit `06e65bea3a778b2dae5af77a7935ae3868ddd4d3`;
+- official `PSn00bSDK-0.24-Linux.zip`, SHA-256
+  `5ada7c9478d795b22bde96ee23d6869290c14a740bcde3d57c01c342a26ded35`;
+- official `gcc-mipsel-none-elf-12.3.0-linux.zip`, SHA-256
+  `228f031a25cf2687d8845fd1421f625bafc211fa27da428e458e80d030a726f8`;
+- PSn00bSDK `mkpsxiso`, followed by MAME `chdman` 0.264;
+- final 15,411-byte CHD SHA-256
+  `58e9754dd2c868d091cbd2401182b5026e436a7b199437fb7dfab039fccb89e7`;
+- checked-in gzip SHA-256
+  `7b1af8fcfcaf052d40fac4696710b1f8b17bc3d6d32f36abd04e4c564d2d0f9f`.
+
+`generate-fixtures.mjs` inflates the checked-in payload and refuses to emit it when the CHD
+checksum differs. The live gate then verifies the exact 15,411-byte artifact via scoped
+Range delivery before starting the actual pinned `pcsx_rearmed` core.
