Step 1-3 used a fixed RULE_SPACE (4 LLM axes + 3 CA axes, each with 3-5 values). The developmental program operated within that fixed space. Bedau OEE requires UNBOUNDED compositional growth — rule space must be able to expand. Step 4 (this experiment): agents may propose NEW values for existing axes (not in initial RULE_SPACE). Accepted novel values are appended to a per-run mutable rule space. Tests whether agents (a) propose novel values at all, (b) get them accepted, (c) build on them in subsequent generations. Falsifiable predictions: - OEE-positive: ≥1 novel value accepted in ≥3/6 runs, AND ≥1 of those novel values gets re-modified in a later generation (compositional depth on novel-value chain).
- OEE-conservative: novel values proposed but rarely accepted (≤1/6 runs). Voters reject anything not in their training distribution.
- OEE-null: agents never propose novel values. Conservative within fixed rule space.
This is CONSTRUCT — new architecture variant that adds genuine rule-space mutability (vs step 1-3 fixed-space modifications).
