description = "Implement RFC-0001 W2 so CP shared-KV extend allocation supports real batch-size greater than one through owner-lane allocation instead of legacy multi_batch fallback. Scope includes request-local owner planning at allocation time, batch-aware alloc_extend_compute_owner support, owner-lane capacity behavior, and focused unit tests."

content = "Implemented W2 batch owner-lane allocation: added request-local batch owner planner, routed supported bs>1 CP shared-KV extend allocation through alloc_extend_compute_owner, removed allocator bs=1 guard, added bs>1 no-legacy-fallback, owner-lane invariant, capacity wait, unsupported fail-fast, and bs1 compatibility tests. Compliance checker returned COMPLIANT. Local py_compile and govctl render/check passed before remote verification."
