Detectability depends on bandwidth, observing time, beam direction, duty cycle and interference. The figure and table share historical Earth-emission assumptions. Proposed orbital and habitability inferences were not performed measurements. A hypothetical relay-station private communication is attributed but unavailable. The paper reports no extraterrestrial detection; named funding is distinguished by recipient.","subjects":["Radio astronomy","Technosignature forecasts"],"people":["Avi Loeb"],"review":{"label":"All eight supplied preprint pages and native layouts; journal and original-data gaps","scope":"A specialist actually read all 33,710 normalized characters and viewed all eight native PDF layouts of astro-ph/0610377v2, dated 19 November 2006. Review includes equations, Figure 1, Table I, acknowledgements and references. Root reviewed the entire frozen analytical report and evidence and verified its inventory; root primary-body reading is false. The abstract describes seven pages while the received file contains eight, including a deferred table. That discrepancy is preserved.","gaps":["These are historical conditional forecasts, not completed surveys, detected civilizations or current instrument and planet-census statements. Beam, bandwidth, duty-cycle, foreground and terrestrial-interference assumptions remain material.","Figure 1 and Table I use a shared historical terrestrial-emission family; they are not independent extraterrestrial observations. No performance replication, fitted target orbit or verified habitability measurement was supplied.","G. Laughlin is credited with a hypothetical relay-station private communication. Its original, date, recipients and supporting evidence are unavailable; this does not establish insider or government programme knowledge.","The acknowledgements assign FQXi and Harvard funds to Loeb, and Packard, Sloan, NSF and NASA support to Zaldarriaga. These attributions were not independently audited and do not establish covert tasking, access or custody.","Journal-version collation, cited originals, original data/code, modern observing outcomes and reviewer correspondence remain unreviewed. A page-three URL extends beyond the native page edge; its missing tail and exhaustive glyph fidelity remain unresolved."]},"familyId":"ARXIV-ASTRO-PH-0610377-V2","citationUrl":"https://bioparity.io/sources/S7714","citation":"Abraham Loeb, Matias Zaldarriaga.
