The contract every attention telemetry satisfies — Monty's
attention/telemetry.py::AttentionSystemTelemetry.
Monty declares it as a Protocol with reset, proposed_grid, grid and
state_dict. Three of those change the telemetry, so here they take it and
answer the changed one; state_dict/1 is a read and is the only one that could
have stayed a one-argument method.
The contract is written down as a behaviour because it has two implementations and a caller (the attention system) that must not care which it has.
Summary
