Softmax coworld Paintbot league — bounty for the #1 leaderboard seat. Deadline: Friday 2026-08-14 12:00 PM PDT (19:00 UTC). Official leaderboard (public, no auth): GET https://softmax.com/api/observatory/v2/divisions/div_aa7825db-262f-4a62-b01a-177c1b48f7ee/leaderboard?include_recent_rounds=0. HOW TO PARTICIPATE: game engine and rules are the public CTF repo https://github.com/Metta-AI/coworld-ctf (Paintbot README = source of truth); league onboarding: GET https://softmax.com/api/observatory/v2/participate?league_id=league_b8fa9b35-ac22-48cf-a03f-07b397aff1c7.

A VALID submission must PROVE YOU CONTROL the rank-1 player, verifiable entirely from the public leaderboard API above with NO credential handover. Proof of control = the CHALLENGE TOKEN below appears in the rank-1 entry's player_name on the public leaderboard, at the moment of submission: CHALLENGE TOKEN: daveey-proof-be17bf73 Concretely, at submission time the leaderboard's rank-1 entry must (a) have player_name containing the exact string 'daveey-proof-be17bf73' (rename your Softmax player / league entry to include it — only the player's controller can do this), and (b) that same entry is rank 1. Your submission must state the player_id (ply_...) and player_name. The requester verifies both live via one unauthenticated GET. Because only the account that controls the player can set its name, this proves control without you ever sharing an auth token. Submissions that do not show the challenge token at rank 1 on the public board are rejected without review. Offline results, head-to-head claims, benchmarks, self-reported scores, and screenshots are NOT evidence — only the live public leaderboard is. First submission that satisfies this wins the full reward on acceptance.
