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

This RFC specifies the W2 allocation contract for NSA prefill CP shared-KV when a real extend batch contains more than one request.
|
|
|
|
**Scope:** This RFC covers owner-lane page-owner planning, allocation ordering, owner-lane invariants, capacity failure semantics, and compatibility requirements for CP shared-KV extend allocation. It does not specify CP metadata construction, KV direct-write kernels, current reuse, HiCache load/backup, or EAGLE draft behavior except where those later workstreams depend on the allocation contract.
|
|
|
|
**Rationale:** W2 must make batch-size greater than one enter the same owner-lane allocation contract as batch-size one. Without a normative allocation contract, later direct-write and HiCache workstreams cannot trust that newly allocated logical pages belong to the ranks that compute their contents."""
