check-bios.cmd: drop literal `^` from BIOS_STATUS (caret survives quoted SET so substring search for `->` never matched). Write X:\bios-fired.flag on flash_done + staged paths so startnet.cmd can detect via if-exist. startnet.cmd: replace `call set` substring-replace with `if exist X:\bios-fired.flag`. Move push to after W:\Enrollment xcopy completes (before Y: cleanup) so dashboard reflects "BIOS firmware update" stage once file staging is done, matching user mental model of imaging order. Tested flag-file logic in win11 VM cmd.exe: missing -> SKIPS, present -> FIRES, removed -> SKIPS. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
