The missing index prefetcher state is expected when MLA/index prefetch is disabled. Logging it as an index-prefetch fallback made the normal synchronous materialize path look like a failed fast path and created noisy reports. This keeps consume-miss warnings for enabled prefetchers, but suppresses missing-prefetcher warnings when the prefetch feature gate is off. Constraint: Index prefetch is controlled by the same MLA prefetch enable gate in the current pipeline. Rejected: Suppress all index prefetch fallback warnings | consume misses still indicate an enabled prefetch pipeline failed to serve a requested buffer. Confidence: high Scope-risk: narrow Directive: Missing prefetcher is not a fallback when SGLANG_CP_SHARED_KV_ENABLE_MLA_PREFETCH=0; do not re-add warning noise without a separate enable gate. Tested: Local py_compile for nsa_indexer.py and test_cp_shared_kv_runtime.py. Tested: Remote g0034 targeted regression set passed 4 tests: disabled sync materialize no warning, consume miss warning, first-layer no-warning, enabled create-skip warning. Not-tested: Full CUDA ETE run with logs.
