      "notes": "The binding disclosure of the DoD deal terms, filed with the SEC. Read in full 2026-08-12 (EDGAR returns 403 without a declared user agent). Confirms verbatim: the Transaction Agreement was entered into on 9 July 2025 (the 'Effective Date'); a commitment for a $150 million loan to support expansion of heavy rare earth separation, to be extended by DoD within 30 days following closing; a quarterly payment per kilogram of NdPr equal to the shortfall between $110 per kg and the benchmark quarterly average price; a 10-year offtake agreement for magnet production from the 10X Facility; and a warrant issued to DoD. Source type 'other' follows the convention used for src-mp-dod-2025 (company document rather than a government instrument), but this is the filed agreement disclosure rather than a press release. Note the event is dated 2025-07-10, the announcement date, while the agreement's effective date is 2025-07-09. Rebuilt 2026-08-12 after the record was lost to an accidental working-tree revert; re-verified against the filing. Full original filing reread on 3 October 2026 for the 10X lifecycle review; the reporting date is not treated as a construction commencement date."
