What
Error telemetry usually replaces the server's message with a generic type-and-status string. A fixed allowlist now exempts six messages, including expired OAuth tokens and oversize requests, so those failures stay distinguishable in aggregate.
Evidence
"OAuth access token has expired. Re-authenticate to continue."
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
