The prompt

Original prompt

Create a Minecraft-inspired browser game in the Minecraft folder. Use similar-looking voxel textures and gameplay while avoiding copied proprietary assets; This has to look exactly like Minecraft, make it faithful. The output must be a single self-contained HTML file that plays directly in a browser.

Recovery status

This is the standardized Minecraft benchmark prompt, verified verbatim in other Minecraft generation sessions. Muse Spark 1.2 was reached through a local shim, and its build session was not found in the local session index, so the prompt is attributed by run convention rather than directly recovered.

Provenance note. First entry on the bench from Muse Spark 1.2, which was reached through a local shim.
