This tool proves that specific exponent patterns cannot correspond to integer Collatz cycles. Unlike testing individual integers, we enumerate the pattern space — proving structural impossibility.

Uniform spectral gap for the Syracuse (3n+1) mod-2^k transfer operator, proved elementarily for all scales (cert <= 0.8536). The earlier cycle-elimination claim is retracted (3x-1 control) - see README/THEOREM.md. Not a proof of Collatz.

Coordinate audit for the Paradoxical Sequence benchmark: separates Rozier–Terracol pure reproduction, our trace_escape sampled-universe baseline, and the RT550 odd-accelerated remaining_K overlay.

Finite-sample observational chapter mapping Collatz waiting-hall events as a state space organized by exit_distance, with miss-front, k-structure corridor, and position-shape selector audits.

A finite-data audit of apparent branching in observed Collatz state transitions under position, side, and basin conditioning.

A finite-sample observational atlas of accelerated Collatz trajectories, extending the waiting-hall analysis into boundary-front geometry, trajectory grammar, empirical flow, and numeric path anatomy.
