Oracle freshness monitor for tokenized stocks and ETFs: reports the age of the latest price update against the feed's heartbeat, flags non-positive or invalid rounds, and states plainly when a check (like sequencer uptime) cannot be verified. Raw round id, answer, and timestamps included for independent auditing.
