What happened to the over 200,000 Mars One applicants, and did any get tested?

Research question: What happened to the more than 200,000 Mars One applicants after the application window closed, and did the one-way plan reach any stage that tested volunteers or hardware?

The records show that Mars One drew 202,586 applications in 2013 and cut the list to 1,058 finalists after several more rounds of reductions 1. Before its bankruptcy, the list had been narrowed to 100 names, with further cuts planned before full-time training 2. The planned training was to take place in a remote location for practicing life in and repairing a Mars-style habitat, but the records do not report that it began 3. The launch was delayed by nearly 10 years from an original 2023 landing, and Mars One later went into administration and was at risk of liquidation, so its 2031 goal was no longer pursued 45. The newest fact dates to February 2019, about seven and a half years before October 2026, and the records do not confirm any volunteer or hardware testing 235.
