What
A check that judges a sync result now returns false when the result is "unreadable" and the cause is host_config, the same way it already did for the cause "other".
Why
An unreadable host_config is no longer treated the same as the remaining unreadable causes in this check.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
The finding does not say what is being synced or what a false result from this check leads to.
