Per-layer prefill-to-decode transfer now finishes per request/rank/chunk, so success-path INFO logs can dominate production logs and hide actual failures. Keep successful finish breakdown and completion messages at DEBUG while preserving nonzero finish status as WARNING.
Constraint: Per-layer transfer is a hot path under CP shared-KV and may produce many batch completions per request.
Rejected: Disable CP per-layer transfer logging entirely | failures still need visible warning-level evidence.
Confidence: high
Scope-risk: narrow
Directive: Do not promote successful per-request transfer completion logs back to INFO without rate limiting.
Tested: PYTHONPATH=python python -m pytest -q test/registered/unit/disaggregation/test_cp_per_layer_transfer.py::TestPerLayerTransferContext::test_successful_finish_does_not_emit_hot_path_info_log
Tested: python -m py_compile python/sglang/srt/disaggregation/cp_per_layer_transfer.py python/sglang/srt/disaggregation/mooncake/conn.py
Not-tested: Full local disaggregation suite blocked by missing local orjson dependency.
