Cache-hit EAGLE/NextN draft extends can enter the draft DeepEP MoE immediately after CP shared-KV attention. The partial current-reuse path is kept for target layers, but draft cache-hit suffixes now use full materialization until draft has an explicit same-layer reuse contract. Next-layer MLA/index prefetch is also gated by the actual model depth, so the single-layer draft model does not enqueue unused next-layer async work.
The temporary stage traces used to isolate the hang are removed. The retained draft current-reuse fallback is a bounded warning because it changes the runtime path intentionally.
Constraint: EAGLE/NextN has one executable draft layer and mirrors target KV state.
Rejected: Keep partial current reuse for draft cache-hit suffixes | reproduced hangs at draft layer0 before DeepEP MoE completion.
Rejected: Keep temporary stage traces | useful for diagnosis but too noisy for normal runs.
Confidence: medium
Scope-risk: moderate
Directive: Do not re-enable draft cache-hit partial current reuse without an explicit draft same-layer reuse contract and ETE validation with CP shared KV + HiCache + EAGLE.
Tested: py_compile on edited Python files; git diff --check; temp trace grep returned no matches.
Not-tested: Local targeted pytest is blocked by missing pybase64 in this environment; full ETE after log cleanup not run.
