Micro-Gate Monotone Inheritance and the Local Positive-Rotation Seal: Dominating [0, 10⁻⁴] from the Atlas-Agnostic Lower Bound at ρ = 0.003, and Completing Research Closure of [0, 0.003]

The micro gate [0, 1e-4] is closed by monotone inheritance (the normalized lower bound H(ρ) is non-increasing in ρ, so 09T's value 0.16529554824965303 at ρ = 0.003 bounds all smaller ρ) plus a 576-cell radial cover; combined with the bridge, the local gate [0, 0.003] is 'RESEARCH-CLOSED' (09F's C3 ≤ 1000 micro plan is superseded). The tail [0.003, π/120] remains open.
