First public release

Known gap: modules 15–22 (hardware and regulatory) were not yet audited at release. Treat quoted standards limits and regulatory statements there as unverified.

Modules audited so far: 01, 02, 03, 04, 05, 06, 07, 08, 09, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33. Remaining modules are queued for the same audit.

Flagged as unverified (58)

Claims the audit could not confirm against an accessible source. They may well be correct; treat them with extra care and tell us if you can confirm or refute one.
