What
In auto mode, a classifier (an automated check) decides whether a sandboxed command may use the network. The sandbox is the restricted environment such commands run in. When that classifier is unavailable, its result now includes retryAfterMs, a number of milliseconds.
Why
The result now says how long to wait before trying the classifier again.
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 uses `retryAfterMs` or whether you see it.
