A8 Stopwatch · MM:SS
MINUTES : SECONDS · 64 A8 seconds per minute
Total: 0 A8 seconds
Ready
Stopwatch reads Core20 elapsed time. Changing moon viewing speed does not change the stopwatch’s rate. Stopwatch is an independent Core20 state-edge witness.
Elapsed time from Core20 state-edge coordinates, not moon animation phase. Whole A8 seconds shown. Human selection of the visual tangent and button timing limit comparison precision.
Prediction / Simulation Rate · MODEL EPOCH-5
Current mode: 1× SKY NOW. Physical source epoch: —.
Sealed Ganymede full-orbit recurrence: — RAW.
Awaiting Epoch-5 model.
- Io: — RAW per displayed orbit.
- Europa: — RAW per displayed orbit.
- Ganymede: — RAW per displayed orbit.
- Callisto: — RAW per displayed orbit.
1× is special: it follows fresh Epoch-7 physical RAW and represents A8's current SKY NOW prediction. Selecting any other rate detaches the display from the current sky and enters simulation.
Returning to 1× discards the simulated position and fetches a fresh physical Epoch-7 snapshot before SKY NOW resumes.
Physical prediction feed
At 1× the four moon positions are anchored to the current physical Epoch-7 RAW counter. Browser interpolation only smooths movement between snapshots. Simulation rates never write to, discipline, or retune the physical source or Core20.
Core20 comparison telemetry
Comparison telemetry only. It does not drive the four-moon Epoch-5 predictive geometry.
Four-moon predictive observer
Io, Europa, Ganymede and Callisto are projected from sealed Jupiter-relative Epoch-5 model driven by the live physical Epoch-7 counter through the qualified Entry 011 handoff. 1× SKY NOW is the current A8 prediction. Every other viewing rate is simulation.
A8 makes predictions. Nature settles the bets.
