In program-based harness generation, every program that parses cleanly without syntax errors belongs to the protocol-compliant harness space \mathcal{H}_\Pi.

Match each formal harness space to its corresponding definition.

Identify which formal space the candidate program succeeded in entering, which formal space it failed to enter, and state the exact formal condition that prevented its entry.

Which issues specifically prevent a protocol-compliant harness in $\mathcal{H}_\Pi$ from qualifying for the executable harness subset ($\mathcal{H}_\Pi^{\text{exec}}$)?

According to the formal definition of the protocol-compliant space $\mathcal{H}_\Pi$, what four specifications does the shared protocol $\Pi$ define for (M, P, A, F)?

Order the nested formal harness spaces from broadest superset to most restrictive subset.

Explain why passing syntax validation to enter $\mathcal{H}^{\text{syn}}$ does not guarantee that a candidate harness belongs to the protocol-compliant space $\mathcal{H}_\Pi$. In your answer, contrast the criteria evaluated for syntax validity with the requirements imposed by protocol $\Pi$.
