Read once, for one account on one subscription tier, against v2.1.190. It isn't a statement about your account. What a flag value here can and cannot tell you

A new feature flag tengu_saffron_credits_only_tiers (defaulting to ["enterprise"]) specifies which subscription tiers must always pay usage credits for Fable 5. Enterprise accounts without the overage tier are automatically treated as credits-only. A companion flag tengu_saffron_picker_dim allows the model picker entry to be dimmed for these accounts.

The overage consent check (yae) was also updated to respect an enabled: false field in the saffron plan config, allowing the server to explicitly disable the consent gate.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
