One public future
Game 2026-08-v1 pins gauntlet-01 and its SHA-256 digest. It is reproducible and inspectable, so it is a competition playground—not research-tier evidence.

Compete on the global game
You and every computer policy face the same visible discs and the same hidden values under gray discs. Play entirely in your browser, then optionally sign in and submit only your column choices. The server replays those choices from the immutable game artifact and computes the score independently.
Signing in is an explicit choice to contribute. A submitted run stores your OAuth provider identity, public handle, game version, compact move sequence, client score, server-verified score, and timestamps. Anonymous games never leave this browser.

Three bits per move
Submitted columns 0–6 are packed into a dense 3-bit stream in DynamoDB. The original JSON move array is not retained.
Server score wins
The Lambda replay rejects illegal, incomplete, or trailing moves. A client/server score mismatch is logged and stored, and only the server score appears in rankings.
