Changelog

0.3.0

Breaking: storage.save and storage.delete are removed; the server no longer accepts client storage writes. client.storage is read-only; module functions and the admin API write player storage.
RudderKernelError lists plan_required and module_limit_reached.

PlayerProfile.balances (CurrencyBalance[]: currency, balance) replaces wallets, and the Wallet type is renamed CurrencyBalance.
PlayerProfile.items (InventoryStack[]: item, quantity) replaces counters.
Catalogs replace resources on the platform; no public type changes.
Module clients generated by rudder client generate 0.3.0 list the current kernel error codes in RudderKernelError.

First release as @rudder/sdk. Not compatible with @rudder/js-sdk 2.x.

createClient({ projectKey }) creates the client; baseUrl defaults to https://api.rudder.build.
Kernel surface only: auth, player (player, identities, wallets, counters), catalog, storage, modules. Revision sync keys are profile, catalog and storage.
State objects expose value (was data), status, error, load(), reload() and onChange().
storage.save(type, data) upserts the single item of a type; storage.delete(type) removes it.
modules.call<T>(module, fn, args?, { moduleVersion? }) resolves to result as T. It always sends args ({} when omitted), one Idempotency-Key per call reused on retries, and X-Rudder-Module-Version: <module>@<version> when a version is given. Retries up to 2 times with jittered backoff on network errors, 5xx and 409 conflict. A 422 rejects with RudderModuleError<C> (code, message, requestId).
Typed module clients come from rudder client generate --lang ts.
Removed: client.resources(slug), client.projectStorage and their types.

Deprecated. Its history is in git before the 0.1.0 commit.
