The streaming paradigm handles all boundary conditions through structural mechanisms rather than conditional logic: sentinel initialization covers the start boundary (no first-iteration special cases), early-exit covers the termination boundary (no post-violation processing), and extend-or-reset covers transition boundaries (no inter-run bookkeeping).
Sentinel+early-exit eliminate boundary code (depth-2) and streaming is the dominant shape (depth-2); together they show streaming's boundary handling is complete — no boundary requires explicit conditional logic
