[BUG] RemoteTrigger tool returns 401 despite valid OAuth on Max plan (tengu_ccr_bridge: false)

What's Wrong?

The RemoteTrigger tool in Claude Code CLI returns HTTP 401 (authentication_error) for all actions (list, create, get, etc.), despite being authenticated via OAuth with a valid Max plan subscription.

Auth status confirms OAuth is active:

{
  "loggedIn": true,
  "authMethod": "oauth_token",
  "apiProvider": "firstParty"
}

Root cause: The GrowthBook feature flag tengu_ccr_bridge is set to false server-side for my account, even though I have an active Max plan. The flag gets overwritten to false on every CLI restart, even after manually setting it to true in ~/.claude.json.

Key observations:

• cachedGrowthBookFeatures.tengu_ccr_bridge: false (should be true for Max plan)
• hasAvailableSubscription: was null (should be true)
• The web UI at claude.ai/code/scheduled works perfectly — I can see and create scheduled tasks there
• Only the CLI RemoteTrigger tool fails with 401
• The MCP scheduled-tasks tool works fine (but it's local, not cloud-based)
• Previously briefly switched to API key auth, then back to OAuth — may have caused desync

Claude Code version: 2.1.87 (latest)
OS: macOS Darwin 25.0.0

What Should Happen?

The RemoteTrigger tool should authenticate successfully using the OAuth token and return results from the /v1/code/triggers API, just like the web UI at claude.ai/code/scheduled does.

The tengu_ccr_bridge feature flag should be true for all accounts with an active Max plan subscription.

Steps to Reproduce

1. Have an active Max plan subscription on claude.ai
2. Authenticate Claude Code CLI via OAuth (claude auth login)
3. Confirm auth: claude auth status shows authMethod: "oauth_token", apiProvider: "firstParty"
4. Use the RemoteTrigger tool with action: "list" → returns 401
5. Check ~/.claude.json → cachedGrowthBookFeatures.tengu_ccr_bridge is false
6. Manually set tengu_ccr_bridge to true in ~/.claude.json
7. Restart Claude Code → flag is overwritten back to false by GrowthBook sync
8. Meanwhile, claude.ai/code/scheduled web UI works perfectly with the same account

Context: User previously briefly enabled API key auth (ANTHROPIC_API_KEY), then switched back to OAuth. The subscription desync may have started at that point (hasAvailableSubscription was null).
