Route supported multi-request CP shared-KV extend allocation through request-local owner plans so downstream direct-write paths can trust flattened out_cache_loc owner lanes. Unsupported page plans now fail fast instead of falling back to legacy allocation.
Include the normative govctl RFC and completed work-item trail in the tracked repository; keep transient superpowers planning outside the sglang branch.
Constraint: RFC-0001 W2 requires no legacy multi_batch fallback for supported bs>1 owner-lane allocation
Rejected: concatenating requests before owner planning | CP ownership is request-relative
Rejected: committing only docs/superpowers plan | it omits the normative RFC and work-item trail
Confidence: high
Scope-risk: moderate
Directive: Preserve flattened request order when changing CP shared-KV allocation; run govctl from the sglang repository root
Tested: remote uv test_nsa_cp_utils.py 39 OK; remote uv test_cp_shared_kv_layout.py 34 OK; remote uv test_alloc_pages_with_owners.py 10 OK; govctl check; git diff --check
Not-tested: CUDA ETE/perf paths beyond focused W1/W2 unit suites
