Fable 5 Included-Usage Limit — New Rate Limit Category

A new rate limit type, seven_day_overage_included, tracks weekly Fable 5 usage for accounts where a defined amount is bundled into the plan. When this limit is exhausted, Claude Code now displays a specific message instead of the generic overage prompt:

• "You've reached your Fable 5 limit" — shown in the model picker and notifications
• "You've used your included Fable 5 usage for this week. Continuing on Fable 5 uses usage credits" — explains exactly what happens next

Previously, hitting any Fable 5 limit while on an account with usage credits would show the generic model-switch / credits dialog. Users on the new included-usage tier now see a distinct, accurate message. The model-switch prompt is suppressed when this limit type is active, since the appropriate next step is purchasing credits rather than switching models.
