Siraj and Loeb argue that a roughly kilometer-scale Borisov nucleus better matches an assumed ordinary Oort-cloud mass budget. An eight-kilometer alternative produces substantial tension with that benchmark, without independently disproving the larger size. Their figure uses four points for three object families, including two alternative Borisov radii. Sparse Poisson bounds do not capture every observing or population uncertainty. This is a conditional argument using reported observations, not a new measurement campaign or artificial-origin finding.

Siraj and Loeb forecast interstellar-object velocity and direction distributions from conventional stellar ejection. Their estimates distinguish 12-object velocity and 180-object angular tests of two ejection models from a separate 12-object anisotropy test. Density, size, sampling and detection assumptions remain uncertain. White-dwarf, outer-cloud and interstellar-medium alternatives are retained. Discovery forecasts and an artifact conjecture are not observations. Manuscript comments and work-level grant support do not establish government access.

Siraj and Loeb propose stellar occultations as a way to find conventional interstellar objects. An idealized all-sky forecast of about one annual event depends on population, size, noise and observing assumptions. Bound Kuiper-belt and Oort-cloud populations are ordinary alternatives, with overlapping timescales. Metadata, citation, figure, axis and model discrepancies remain unresolved. This supplied preprint reports forecasts rather than detections; work-level grant support does not establish government access.

Loeb models a population mass budget for 3I/ATLAS and offers ordinary cometary-core or rarer-population alternatives. Technological design is conditional speculation; albedo, size, selection and reservoir assumptions remain explicit, with no artificial-origin detection or independent model validation.

Siraj and Loeb model captured interstellar minor-body orbits using inherited density, population and size assumptions. Eight catalogue objects are possible candidates, not confirmed interstellar origins or extraterrestrial artifacts. Native Oort-cloud bodies are an explicit confound. Model convergence and forecasts do not supply independent observations. Native table, selection and population-normalization qualifications remain unresolved; detection bias and original calculation gaps are preserved. Manuscript assistance and work-level funding do not establish government tasking or custody.

Forbes and Loeb forecast near-Sun interstellar-body encounters and propose spectroscopy. Encounter rates and candidate probabilities depend on uncertain density, orientation, population and detection assumptions. Listed probabilities do not confirm individual origins. Ordinary cometary explanations, bound-orbit caveats and an ISON non-detection remain explicit. Parameter and catalogue-filter discrepancies are unresolved. Forbes’s fellowship is distinct from work-level grant support; neither establishes government access.

Siraj and Loeb infer an interstellar meteor trajectory from catalogue inputs and an assumed error model. The paper attributes uncertainty information to Heavner and quotes a reported DoD statement, with Worden, Daniels, Shaw, Mozer, an anonymous analyst and Hurd credited for distinct clarification roles. Original correspondence and classified data were not received. Conditional confidence, ordinary bound comparators, population assumptions and mass-budget tension remain. Government review does not establish researcher classified access, artificial origin or recovered material.
