Freedom Birth Rate, Broadworm Residual Dynamics, and the Reproduction of the n = 4, 5, 6 Polygonal Extremizers

Recovers the seven general-n conjectures of the 2007 broadest-arc paper and numerically reproduces the n = 4, 5, 6 candidates (t₄ ≈ 0.438208, t₅ ≈ 0.438438, t₆ ≈ 0.438695, not certified) against the broadworm constant β ≈ 0.438925369; shows that the freedom birth rate (2 per segment) is not the residual contraction rate; a local test at n = 8 fails to activate new freedom.
