What's Wrong?

In Claude Pro plan 1M Context is automatically activated regardless of CLAUDE_CODE_DISABLE_1M_CONTEXT=1 in ~/.claude/settings.json and claudeCode.environmentVariables in VSCode settings. Happens with auto-compact.

What Should Happen?

It should stay in 200k. With this bug it's very difficult to work.
