[BUG] Fast mode reports 'disabled by your organization' despite being enabled in Platform and settings

Bug Description

Running /fast in Claude Code returns:

Fast mode unavailable: Fast mode has been disabled by your organization

Despite fast mode being enabled in both locations:

1. Local settings (~/.claude/settings.json): "fastMode": true
2. Claude Platform (platform.anthropic.com > Claude Code > Preferences): Fast mode toggle is ON

Environment

• Claude Code version: 2.1.62
• OS: macOS
• Organization: Fantasy Metals
• Auth method: claudeai (via forceLoginMethod in project settings)
• Model config: opus

Steps to Reproduce

1. Confirm fast mode is enabled in Claude Platform under Claude Code > Preferences
2. Confirm "fastMode": true is set in ~/.claude/settings.json
3. Start a new Claude Code session
4. Run /fast or /fast on
5. Observe error: "Fast mode has been disabled by your organization"

Expected Behavior

Fast mode should activate, matching the organization's Platform setting.

Actual Behavior

Fast mode reports it has been disabled by the organization, contradicting both the Platform UI and local config.

Screenshots

Platform showing fast mode enabled:

)

(The Platform clearly shows "Fast mode" toggled ON under Claude Code preferences for the Fantasy Metals organization.)

Additional Context

• No settings.managed.json or enterprise override files exist
• Restarting the session does not resolve the issue
• The error message appears to be a cached or stale org permission check that doesn't reflect the current Platform state
