Under the hood
Credential storage telemetry now reports which backend or fallback chain was actually used
What
Telemetry sent when OAuth login tokens are saved (or fail to save) now tags the storage backend more precisely. It recognizes keychain, plaintext, and windows-credman, as well as composite fallback chains like "<x>-with-<y>-fallback", and reports anything else as other.
Why
This gives more detail on which credential storage method was actually used, including cases where the system fell back from one backend to another, which helps diagnose storage issues across different platforms.
