What
Claude Code runs an access check called the Mantle probe. When it reports the outcome in its usage data, it used to mark access as available only when the result was "accessible". It now does the same when the result is "outdated".
Why
An "outdated" result is now counted as access being available in what gets reported. It may also affect what Claude Code does next.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
It is not clear what the Mantle probe checks or whether anything besides reporting changes.
