  "abstract": "We investigate whether the dynamical merger branch of massive boson-star collisions can be inferred from the gravitational waveform without supplying the intrinsic source parameters. Using an existing equal-mass, head-on numerical-relativity catalogue, we construct branch-conditioned reduced-basis surrogates for the real $(2,0)$ and $(4,0)$ modes and perform parameter-blind waveform inference. On a frozen test set of 60 held-out samples, the correct branch is recovered for all samples using either mode, showing that the branch information is not confined to the dominant $(2,0)$ channel. The inference also recovers $|ϕ_c|$ with a mean relative error of $4.30\\%$ and selects the correct $λ$ from $\\{10,50,100,300\\}$ in $68.3\\%$ of the test samples. These results demonstrate waveform-based branch and source-parameter inference within the present noiseless numerical-relativity catalogue.",
