Streaming's structural boundary handling produces correct results for all observed boundary inputs: sentinel initialization handles empty/degenerate inputs without special-case code, and sentinel values never collide with valid data under LeetCode's constraints — making the paradigm empirically robust at boundaries, not just structurally sound.
One antecedent establishes structural completeness of boundary handling, the other establishes sentinel safety under constraints; the combination claims empirical robustness, which is invalidated if sentinel collision occurs (rook) or degenerate input crashes (pillow n=1)
