Pull Request Overview

This PR enhances SDK validation by propagating and verifying a base64 signature through the cascade flow, refactors event data handling to use typed EventData, and extends the task cache to track ActionID and transaction hash.

• Add signature generation in E2E tests and wire signature through StartCascade and CreateCascadeTask.
• Introduce validateAction & validateSignature in ManagerImpl, update cache storage and event handling for transaction hashes.
• Refactor logging/events to use unified LogEvent and typed EventData, update adapters and types accordingly.

• [nitpick] The actionId field on CascadeTask appears redundant since BaseTask.ActionID is used elsewhere; consider removing the lowercase actionId field to reduce confusion.

func NewCascadeTask(base BaseTask, filePath string, actionId string) *CascadeTask {

sdk/task/cache.go:134

• There are no existing tests covering UpdateTxHash or the new ActionID/TxHash fields in TaskEntry; add unit tests to ensure these new behaviors are validated.

func (tc *TaskCache) UpdateTxHash(ctx context.Context, taskID string, txHash string) bool {

sdk/adapters/lumera/adapter.go:12

• The code uses fmt.Errorf in new methods but fmt is not imported; add import "fmt" to avoid compile errors.

The variable name base64EnTcketDataHash is misspelled and unclear; consider renaming it to base64EncodedDataHash for clarity.
