Gas-Bounded Transfer Triggers for a Launch Queue: Failure Isolation, Retry State and Operator Dependence

Attaching background work to token transfers can distribute execution opportunities, but it can also make an unrelated queue failure prevent a user from transferring an asset. This report examines LaunchCursorTokenV3, which uses eligible transfers through a configured pool to attempt one bounded scheduler step after updating token balances. The scheduler processes fresh entries in last-in-first-out order, prioritizes eligible exits and moves failed work into timed retry structures. A bounded self-call isolates scheduler failure from the parent transfer. Five existing unit tests passed after fresh isolated compilation, covering successful work without nested reentry, failed opens, failed work during a sell, insufficient gas for background processing and stale-entry cleanup. The result is a local demonstration of transfer-path failure isolation. Queue admission, price plans, notifications and emergency recovery still depend on privileged roles and a trusted executor. Transfer-triggered processing therefore does not establish autonomous discovery, keeper independence, guaranteed completion or investment performance. The study connects failure isolation to user agency while identifying the operating and cost evidence required to assess access and accountability. Preparation of this report was assisted by Codex.
