TOS-TIER-001Not included in your planThat feature is not on your plan
What happened
The feature exists and works — your current subscription tier does not include it.
What to do
Upgrade from the billing screen, or ask us what the feature does before deciding.
This is a permissions or plan boundary rather than a mistake — someone else can lift it.
Quote this code when reporting the problem. It identifies the exact check that failed, which the wording alone does not.
