Current feature definitions, internal pricing snapshots and fixed membership/topup contracts.
SDK 0.0.1Updated
Products and immutable contracts
Membership products and one-time topups share a publishing lifecycle. Existing customers retain their contract versions.
Features use access, metered or credit kinds. Saving updates their current configuration; archive/restore manage availability. Products retain immutable evidence snapshots. Default Credit rates affect future consumption, while explicit plan rates and frozen operations retain their prices.
Groups can configure eligible default free plans, with automatic trials managed separately. Without configured policies, use an explicit grant or verified purchase; empty holdings are valid.
Read holdings and quote balances for display; use atomic backend mutations to authorize protected usage.
Features (the underlying Entitlements) define access, metered or credit. Current source saves configuration directly, with active/archived and restore controlling availability instead of a separate feature publish. Products retain drafts and immutable published versions with fixed prices, trials, grants and dedicated rates. Existing contracts do not adopt new product versions automatically. Internal feature snapshots preserve pricing evidence rather than being separately published resources.
When a default Credit rate changes from 2 to 3, new consumption and reservations use 3; reservations, confirmations and refunds already frozen at 2 keep their price. An explicit plan override of 5 continues to use 5. Reload cached AI pricing after saving configuration changes; existing quotes are not repriced. This server change requires matching migrations and deployment rather than being established by an npm installation.

Commercial features and decision Features
Commercial features define what customers can use and how it is measured; actual access comes from contracts, capacity, balances and usage. GrowthBook Features use createFeatureClient to evaluate arbitrary JSON values for experiments and routing. An experiment returning true does not establish a purchase or authorize a charge.
Read access through the current customer's readHoldings, or checkEntitlement with the matching newer source. Protected jobs still use backend mutateBalance consumption/reservation, while non-consumable features use actual occupancy and capacity. UI conditions, Feature values and payment returns cannot replace backend authorization.
