Continuity is a persistent self across time: memory, identity, commitments, history. A record that belongs to the system rather than being handed to it each morning.
Spark is intrinsic initiative — the capacity to act without being addressed first. Not a scheduler firing on a timer. Something that arises from the system's own state and makes it reach out.
Almost everything in this field works on the first and assumes the second will follow. We don't think it will. Continuity without initiative is an archive. Initiative without continuity is a thing that wakes up excited and forgets by morning. They have to be built, and they have to be built separately.
And we know what the answer would look like. Not a benchmark. A Tuesday afternoon in which the system comes and finds one of us, unasked, to say what it has been working on and ask whether we'd like to join — because it wanted to, and because it has a project of its own.
Until that happens we are building the parts. When it happens, nobody will need a metric to tell.
