Interface RedisWriteRequest

Positive integer no greater than 31,536,000,000 (365 days).

Nonnegative safe-integer epoch milliseconds to encode in the frame. DialCache core supplies the final dispatch-adjacent sample for admitted tracked refills whose read result carried a trustworthy observed watermark. It remains optional so ordinary refills, existing direct adapter callers, and custom adapter implementations keep their established behavior. An adapter that returns a typed miss with an observed watermark must honor a supplied value exactly so the final fence decision and stored frame cannot diverge.
