Mru Flight has no qualification evidence. The demo has run once in orbit, as a user-space experiment on ESA's OPS-SAT PRETTY (October 2026); that is not qualification. Do not use it to control anything that can cause harm.

In scope:

• The decision core (quorum) and its C interface (quorum-ffi): a wrong verdict for some set of replies, or a crash.
• The demo (quorum) and the bench: a way to make the voter deliver a value that no replica agreed on.
• The F´ components in fprime/Mru.

Only the latest release gets fixes.
