I can safely say I would never have been able to figure this out were it not for your data, thank you.
The problem was that I had never actually seen the case of an inactive mdraid array, and inxi had made some assumptions which did not prove out to be correct, that is, it assumed the data structure would remain the same for active and inactive mdraid arrays. This is not the case. Here's your data working correctly now, thanks.
RAID:
Device-1: md127 type: mdraid level: N/A status: inactive size: N/A
Info: report: N/A blocks: 2136 chunk size: N/A
Components: Online: N/A Inactive: 1: sda0
