  "abstract": "Classical Be stars are rapidly rotating B-type stars surrounded by gaseous circumstellar disks, but the origin of their angular momentum remains uncertain. We investigate whether observed Be-star multiple systems are dynamically compatible with triple-assisted interaction, in which a tertiary companion drives Kozai-Lidov (KL) eccentricity excitation in an unresolved inner binary. We combine speckle-interferometric detections, reported inner periods, and proper-motion anomalies (PMa) with synthetic populations of hierarchical triples. Accepted configurations must satisfy dynamical stability, secular-timescale, inner-periastron interaction, and observational constraints. Refined mass-aware simulations identify HD 35079 and HD 55606 as the clearest period-plus-speckle dynamical matches. HD 205329 remains dynamically plausible but depends on the approximate PMa constraint. For HD 41335, the period-plus-speckle and PMa-plus-speckle constraints are separately compatible, whereas imposing all three simultaneously yields no accepted configurations at the adopted tolerance. HD 37330, HD 41600, and HD 71510 are additional PMa-dependent hierarchical-triple candidates. An independent angular-momentum estimate indicates a median required accreted mass fraction of approximately 4.8% under the adopted assumptions. We conclude that several observed Be-star multiple systems admit stable, KL-active architectures capable of driving inner binaries toward interaction. These results establish dynamical plausibility rather than a confirmed evolutionary history and motivate further speckle, spectroscopic, and astrometric monitoring.",
