credential storage is not available on the web

Error message

credential storage is not available on the web

What it means

Raised in the gpui web platform's credential handling: write/read credentials is invoked, but browser environments provide no secure credential-storage backend, so the platform stub rejects the operation. It is a capability guard, not an authentication failure.

Solutions

1. Use the Web Authentication / Credential Management APIs or server-side storage on the web
2. Detect the platform and skip secret-storage features in web builds
3. Handle the sentinel so auth flows fall back to in-memory or session-only credentials
