Semantic Substrate

What is Temporal?

TemporalThe layer that treats time as first-class, governing how an agent schedules, sequences, and reasons about events.

Temporal is the primitive that answers when, and in what order? Autonomous work unfolds over time, and correct behavior depends on sequence, timing, and history.

It is the layer where memory and planning meet. Temporal reasoning lets an agent honor deadlines, replay what happened, and act on what comes next.

Where temporal sits in the stack

In the four-layer architecture of the agentic web, temporal is a Cross-cutting concept — it applies across every layer of the stack. See the thesis for how the layers compound.
