A minimum requirement for the Watabe-Claude Method (WCM) to function as a general-purpose 4D occupancy-statistics scanner is that it can correctly distinguish among well-characterized dynamical systems. This paper establishes and publishes, for the first time as a citable record, the WCM Attractor Zoo: a twelve-system clarity-index fingerprint catalogue spanning continuous chaotic flows (Lorenz, Rössler, Duffing, Chen), a discrete chaotic map (Hénon, Takens-embedded), a high-dimensional delay system (Mackey-Glass), two non-chaotic references (a quasi-periodic torus, pure white noise), a diffusion process (random walk), and three number-theoretic/quantum-chaotic sequences (Riemann zeta zero heights, GUE random-matrix eigenvalues, prime gaps). Five fingerprint classes emerge empirically: PERSISTENT (Rössler, Duffing, Hénon, Mackey-Glass, and, notably, both GUE eigenvalues and Riemann zeta zeros — independently corroborating the zeta-GUE spectral correspondence at the occupancy level) ; SIGNREVERSE (Lorenz and Chen, both members of the Lorenz family, dip below the null mean at intermediate depth before recovering) ; SHORTMEMORY (a quasi-periodic torus and, notably, prime gaps, which collapse to null-consistent by depth 3 — the specific finding referenced, but not previously published, in Bridge Paper Q's Finding BQ-1) ; and FLAT (white noise, the true negative control). A twelfth system, the random walk, produces a numerically PERSISTENT-looking fingerprint despite having no genuine low-dimensional attractor by construction, and is reported as an explicit methodological caution rather than a positive finding. This paper resolves an internal citation gap in Bridge Paper Q, whose Finding BQ-1 referenced this catalogue's prime-gap result before it existed as a citable publication. We protect the Life using The WCM.
