Event log
How it works
Models the Starlink link going up and down, queues completed Timeback lessons locally while offline, and drains the queue on reconnect — tracking uptime, latency, and a live event log.
What's real
- ✓Queue, uptime, and drain logic are real and tested: offline work is never lost
Demo limits — honest about it
- ○This is a SIMULATION of the link — it does not measure a real Starlink connection
- ○Latency and up/down events are modeled, not live telemetry
In the field
Starlink is the school's only link; the whole point is that a dropped connection never stops learning.
