  "abstract": "The longstanding issue of whether horizonless compact objects can mimic black holes at horizon scales is addressed, a problem that persists because the shadow diameter alone is degenerate across a wide class of geometries. For slowly rotating traversable wormholes, we precisely formulate the optical appearance as a set of observables derived from equatorial null geodesics, yielding necessary and sufficient conditions for a multi-parameter fingerprint. Using a new lapse function that interpolates between exponential and rational redshift profiles, we obtain the photon-sphere condition, the strong-deflection lensing coefficients, and the Lyapunov exponent in closed form. The equations yield two families of wormhole solutions dependent on logarithmic and exponential entropy parameters. We compare the resulting quantum-modified spacetimes with Kerr and four regular black holes. The shadow diameter is shown to be tunable to within $5\\%$ to $11\\%$ of Kerr for all models considered, so that $|R_{\\rm sh}^{\\rm WH}/R_{\\rm sh}^{\\rm Kerr}-1| \\lesssim 0.11$ and the shadow alone cannot separate the models. The degeneracy is lifted when the rotational asymmetry, lensing coefficients, Lyapunov exponent, and orbital frequency are combined: for the $5$-component fingerprint $\\mathbf{F}=(\\Arot,\\abar,\\bbar, \\Lya,\\Oph)$, the fractional deviation $Δ_i=(F_i^{\\rm WH}-F_i^{\\rm Kerr})/ F_i^{\\rm Kerr}$ satisfies $|Δ_i|\\gtrsim 0.05$ for every component, with the largest departures in the second lensing coefficient and the Lyapunov exponent. The combined discrimination signal reaches a signal-to-noise ratio of about $3.8$ to $3.9$ against Kerr and about $3.7$ against the Kazakov--Solodukhin benchmark, which is sufficient to break the shadow-diameter degeneracy at the $10\\%$ measurement level.",
