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 It now does the same when the result is "outdated".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An "outdated" result is now counted as access being available in what gets reported.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.

The writer flagged doubtIt is not clear what the Mantle probe checks or whether anything besides reporting changes.
