Version: Retrieved for the candidate pack on 2026-10-28 (SHA-256 147cbbeb354123dc1b457e368c59d45f9d74986036997731d6c68819d515e15b). Microsoft blog post as served on 2026-10-28; dated Nov 18, 2025.

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 (19 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 (SHA-256 a12faa166c709246f7e9685a70a30c2873d5ff4110824f8f461cc41efa7fe4bc; the bytes differ from the pack’s retrieval). 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 60) answered the record’s question blind from fresh retrievals and agreed with the record. No human editorial review.
