`kaal:entity:action-space`

**Status.** derived

This node is assembled mechanically from the 2 claims that carry the concept tag `action-space`. It is a roster of what the corpus says under this term. It is **not** an adjudicated definition: no single statement here has been ruled canonical, and no first-appearance call has been made. Read the claims and judge for yourself.

- [6655138-004](https://wulfkaal.github.io/claims/6655138-004) [definitional/argued] -- In Neoclassical analysis the action space is a parameter of the model and the agent is a chooser within it, whereas in Computative Economics the action space is an output of the agent and the agent is a generator over it; every operational difference between the two architectures follows from this parameter versus output distinction.

- [6655138-016](https://wulfkaal.github.io/claims/6655138-016) [mechanism/argued] -- The HDCA settlement loop is closed in the topological sense: every job exits as resolved-validated or resolved-rejected and the system returns to a structurally identical state with only reputation scalars updated, so the set of possible actions never changes.
  > This is its central distinguishing feature relative to the HDCA settlement loop, which is closed in the topological sense: every job that enters the HDCA loop exits as either resolved-validated or resolved-rejected, and the system returns to a state structurally identical to where it began
