What

When Claude Code downloads file attachments (used when resolving bridge attachments via OAuth), it now tracks the slowest download time and the total number of bytes downloaded in a batch, and reports these numbers in a new telemetry event.

Why

This gives visibility into attachment download performance, which can help identify slow or oversized downloads.
