Run experiments and learn fast — this is where hypotheses become evidence.

The Execution layer runs the experiments that test each intent. It moves the signal — turning hypotheses into evidence as fast as possible.

Loops here are short, instrumented, and designed to learn. The output is not just delivery; it is knowledge the portfolio can act on.

This is the most active layer in the system. It is where Intent Engineers and Loop Leaders operate day-to-day, running Plays within Playlists within time-boxed Loops.

The critical insight is that execution in Symbiosis is not about shipping features — it is about generating evidence that flows back up to the Portfolio layer so better decisions can be made. Every Play has an Expected Outcome and an Abort Condition, making it a falsifiable experiment rather than a task on a backlog.
