What's Wrong?

Environment: Claude Code 2.1.74, Max plan, Linux, Node v20.20.0, zsh

CLAUDE_CODE_ENABLE_PROMPT_SUGGESTION=true is set in ~/.claude/settings.json under env. Tested in both JetBrains JediTerm and direct SSH terminal — no
suggestions appear.

Telemetry logs (~/.claude/telemetry/) contain tengu_prompt_suggestion events showing:
{ "outcome": "suppressed", "reason": "disabled", "prompt_id": "user_intent" }

The client correctly requests suggestions but they are suppressed server-side with reason "disabled". Is this feature still in limited rollout, or should it be
available for Max plan users?

What Should Happen?

grey text in the prompt with suggestions, with tab can confirm/submit
