What's Wrong?

Affected versions: v2.1.78 and earlier (confirmed), v2.1.79 (likely still affected in VS Code/Cursor extensions)

Behavior:
When Claude Code is launched via the Claude Desktop app (entrypoint: claude-desktop, terminal.type: non-interactive), the OTEL metric attributes are missing user.email, user.account_uuid, and organization.id — despite the user
being authenticated via OAuth (is_claude_ai_auth: true).

Expected (per docs): user.email is documented as "Always included when available" for OAuth-authenticated users.

Root cause (inferred): C3() returns D8().oauthAccount — but when launched non-interactively via Claude Desktop, ~/.claude/.claude.json does not exist (no oauthAccount persisted), so the OTEL resource attributes are initialized before identity is available.

Confirmed working: v2.1.80 via standalone terminal (iTerm.app) — all fields present.

Steps to reproduce:

1. Install Claude Desktop app on macOS
2. Configure OTEL telemetry export (CLAUDE_CODE_ENABLE_TELEMETRY=1, OTEL_METRICS_EXPORTER=otlp)
3. Open a Claude Code session via the Desktop app
4. Observe: MetricAttributes contains user.id but NOT user.email, user.account_uuid, or organization.id

Impact: Enterprise/team telemetry dashboards cannot identify users from mac Claude Desktop sessions.

What Should Happen?

Expected (per docs): user.email is documented as "Always included when available" for OAuth-authenticated users.
