Added

• feat(probable): unified Web3 authentication lifecycle (#1614). Adds getAuthNonce, loginWithSignature, logout, isSessionActive, and verifyL1/verifyL2 to the Probable exchange, with in-memory session storage on the base class, exposed through both SDKs.

Security

• Session credentials are never exposed over the network. [#1614] as submitted exposed getSession as an HTTP/RPC endpoint that returned the full session credential set (apiKey/apiSecret/passphrase) keyed by a public wallet address — on a shared/hosted deployment any caller could retrieve another user's trading secrets. Before landing, getSession was added to EXCLUDED_METHODS in generate-openapi.js, so it is omitted from method-verbs.json, the OpenAPI spec, and the generated SDK clients; it remains an in-process helper only. The signature-gated loginWithSignature (which returns the caller's own freshly minted credentials, only after they prove wallet ownership) and the boolean isSessionActive remain available.
