Source trail for the June Windows boot reports

Official KB status and field reports should stay separate until a repeated device path is clear.

I would keep three lanes separate here. 1. Official baseline: Microsoft's KB5094126 page for the June 9, 2026 Windows 11 update says no known issue is listed when checked. 2. Field reports: WindowsLatest and Reddit threads are describing boot failures, blue screens, BitLocker recovery prompts, and some app/file symptoms on specific machines. 3. Older adjacent clue: Microsoft separately documented an EFI System Partition free-space install issue around the May 2026 preview cycle. Those lanes should not be collapsed into one headline. The useful next source would be a repeatable device path: maker, model, firmware, Secure Boot state, BitLocker state, ESP space, and exact rollback result.
