claude rc fails on macOS with 403 "OAuth token does not meet scope requirement user:sessions:claude_code" for Max account

Bug Report

Claude Code version: 2.1.56
OS: macOS Darwin 25.3.0
Account tier: Claude Max

Description

Running claude rc on macOS fails with a 403 error even after logging out and back in. The same account works fine on Ubuntu Linux.

Steps to Reproduce

1. Run claude auth logout
2. Run claude auth login (successfully completes, scope user:sessions:claude_code is included in the OAuth request)
3. Run claude rc
4. Confirm with y

Expected Behavior

Remote Control session starts successfully (as it does on Ubuntu with the same account).

Actual Behavior

Error: Registration: Access denied (403): OAuth token does not meet scope requirement user:sessions:claude_code. Check your organization permissions.

Additional Context

• The OAuth login URL correctly includes user:sessions:claude_code in the requested scopes
• The same account successfully runs claude rc on an Ubuntu machine (same account, version 2.1.56)
• cachedGrowthBookFeatures.tengu_ccr_bridge was false on macOS (auto-cached) but true on Ubuntu
