Builds path (b) from §26 -- a leaf permanently serving two DIFFERENT compatible programme codes at once, extending leaf-sharing's same-code multiplicity mechanism to different-but-compatible codes. Architect-declared `co_locate` pairs (validated against interchangeable()'s S1-S4 bounds, no transitive closure so the b3v chain problem can't recur), threaded through graph.py's checks via a new leaf_codes() resolver and fitness.py's quality terms (additive size, stricter-of-both width/proportion). Construction-time only, gated behind `multi_use` (default OFF, bit-identical when off). End-to-end A/B (20k evals x 3 seeds x 2 programmes) came back net negative: harbor-house -4.0% but health-centre +24.5% worse (3/3 seeds), because fusing different codes' shape targets via stricter-of-both can impose a tighter joint constraint than either code needed alone, which the tightly- packed health-centre programme can't absorb. Written up as DESIGN.md §33; multi_use stays default OFF, no default-flip recommended.
