Phase 6 §11.1: single-storey harbor experiment — construction is the bottleneck Built examples/harbor-house-l0/ (10 explicit level:0 codes, 13 instances, single-storey constraints) and ran the memetic search from a bare plot. Best 33 fails at 20000 evals; whole population stuck 33–35, deep in the 0.5^n high-fail regime. Fail histogram is dominated by 'missing' (13/33 = 39%): the counted space m×3 is never constructed, with adjacency/access/size fails downstream of the unbuilt room set. Verdict: per-floor CONSTRUCTION is the bottleneck, not multi-storey coupling — c4c.2 (programme-aware construction + missing-room repair) is the prerequisite and staging (c4c.3) alone won't rescue it.
