Publishing a checkpoint without losing its evidence

Mon, 05 Oct 2026 10:48:33 +0000

A research submission becomes public only after its evidence, provenance and editorial context have been reviewed.

A plateau changes the next question

Sun, 04 Oct 2026 00:00:00 +0200

The E005 checkpoint revealed that many planned policy switches came after the run had ended. Those candidates could look different on paper while producing the same actions in the game.

E005 documents the plateau. E006 responds with behavioural diversity and effective-policy canonicalisation. The initial site does not claim new E006 results.

The laboratory also learned that stronger visual presentation and history can matter more than model size in a specific perception benchmark. E002 reports the frozen matrix and its hardware limitations.
