…ha.1 Replace the CDN-loaded @zama-fhe/relayer-sdk with @fhevm/sdk as a build-time dependency. Workers now use FhevmClient (action-based API) instead of FhevmInstance (method-based). EIP-712 typed data is stored alongside credentials and passed through the full decrypt pipeline for permit parsing. Key changes: - Rewrite web and node workers for @fhevm/sdk client API - Add StoredEIP712 type to credentials for permit reconstruction - Define relayer types locally instead of importing from @zama-fhe/relayer-sdk - Use @fhevm/sdk return types for EIP-712 response data - Pass eip712 through decrypt pipeline (credentials → token → relayer → worker) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Widen ClearValueType to include `number` for SDK's branded uint8/16/32 - Remove all `as unknown as Hex/string` casts (SDK branded types are subtypes) - Remove redundant `client as FhevmClientInstance` casts after assertClient - Type decrypt result mappings directly as response types - Add missing `eip712` field to cleartext test fixtures - Fix EIP-712 test expectations from string to bigint - Regenerate API reports for updated public surface Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Move @fhevm/sdk/actions/chain imports to dynamic `await import()` in handleCreateEIP712 and handleCreateDelegatedEIP712, matching the existing pattern for @fhevm/sdk/ethers in handleNodeInit. Update API reports. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

The migration from CDN-loaded @zama-fhe/relayer-sdk to build-time @fhevm/sdk bundles WASM binaries (~7.2 MB) inline. Raise limits to match the new architecture: ESM 6 MB, CJS 2 MB. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Escape package names in JSDoc comments so api-extractor does not misinterpret them as TSDoc block tags. Regenerate API reports. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
