The Suncatcher paper (November 2025) reports proton-beam tests in which Trillium TPU HBM showed irregularities after 2 krad(Si), about three times the authors' five-year requirement of 750 rad(Si).

One recorded claim. The claim panel gives its qualification, the source passages with their place in each source, and how it was checked.

Role: Context
Register (kind of text): Nonfiction
Missing element: a statement that orbital radiation requires mitigation: it reports a ground test with a margin over the authors’ requirement

Scope and limitsA proponent's ground test result, recorded as context: it shows radiation effects and a margin, not in-orbit performance.

Source excerpt

“In our tests, HBM-specific stress tests began to show irregularities after a cumulative dose of 2 krad(Si), which is almost 3× our minimum requirement for TID survival of 750 rad(Si).”

Reuse: No open redistribution licence asserted. Bibliographic metadata, editorial paraphrases and short attributed quotations (at most 50 words each). Recheck terms before wider redistribution.
Check notes: Candidate pack passage, compute, power and orbit (research/compute-power-orbit). The quotation (30 words) matched the text retrieved for the candidate pack on 2026-10-28 and again at admission on 2026-10-30, in a fresh retrieval whose SHA-256 equals the pack’s. Matching ignored differences of whitespace, case, quotation marks, dashes and Unicode compatibility forms, so the source’s typography can differ. A cross-family machine check (2026-10-29/30, item 98) re-read the record’s sources and found full support. No human editorial review.

Status and meaning

Editorial status. Not reviewed by an editor. An exploratory record that no editor has accepted. This status does not say whether a person has read any linked passage. Each evidence record above shows how it was checked.

Relation. A passage of the document bears on the proposition without meeting its criterion; the record names the missing element. It is not an articulation and implies no influence.

Date. Date of publication, as the source gives it.
