We introduce ChainRF, a Bayesian prior that links RF burst timings to on-chain mempooldynamics and protocol heartbeats. ChainRF conditions a GM-PHD tracker (bearings + GhostRF delay) on mempool windows and fee-pressure regimes, yielding closed-form MI bounds thatprice dwell K under temporal alignment. A depth-2 NBV planner maximizes information persecond while ActionGate prunes unsafe branches (I1–I12/E1–E4). … Continue reading ChainRF: On-Chain Timing Priors for RF Event Attribution
