@stigg/cache-core provides the shared cache entities, entitlement mapping, and in-memory cache service used across Stigg’s SDKs (@stigg/node-server-sdk, @stigg/js-client-sdk, sidecar) and persistent-cache-service. It has no store implementation of its own — see Cache Redis Store for the Redis-backed store.

  • Fixed: CreditAccessPropagator no longer marks a credit-backed feature InsufficientCredits when its credit entitlement has a soft limit and the balance reaches zero.

  • Added: cache reads (getEntitlements, single-entitlement reads) now return the time the customer’s entitlements were written.
  • Changed: the usage record on a cached entitlement is now optional. Readers substitute the same zero-usage placeholder when it is absent, so evaluation results are unchanged, and the persisted format is unchanged.
  • ⚠️ Changed: the usage write timestamp now lives on UsageData. CacheMapperResult is removed, fromInput no longer returns a second timestamp collection, and UpdateUsageParams.usageTimestamp is removed. Only affects code that builds directly on cache-core.

  • Changed: cache-core no longer depends on @stigg/api-client-js. The enumerations used in cached entitlements are now declared in cache-core itself, as string-literal unions with same-named namespaces, so values arriving from the API client are accepted unchanged and Foo.Bar call sites keep working. Its only dependencies are now dayjs and lodash.

  • Versions 1.17.0 through 1.26.0 (2026-06-23 to 2026-08-12) carried no functional change to cache-core itself. Each only bumped the package version to track releases of other packages in the monorepo.

  • Added: hasSoftLimit on CalculatedEntitlement, so any store built on cache-core reflects a wallet’s soft-limit configuration. Requires @stigg/node-server-sdk v4.45.0+ on the reader side to take effect; older readers ignore the field.

  • Security: patched vulnerable transitive dependencies.
​
2026-03-30
  • Changed: InMemoryCacheService no longer depends on lru-cache, and EntitlementsMap takes an array of entitlements instead of an iterable.
​

  • Initial release. Extracted the cache entities, entitlement mapping (CacheMapper, accessDeniedReasonMapper), and in-memory cache service, including credit entitlement support, into a standalone, shared package consumed by persistent-cache-service, @stigg/node-server-sdk, @stigg/js-client-sdk, and the sidecar. No behavior change from the extraction itself.
