- `[2026-07-07]` **vLLM 0.24.0 qwen3_5 LoRA application = silent no-op (#47639).** Adapter loads HTTP 200
  but zero deltas at inference. NOT quant (NVFP4 AND FP8 both inert). NOT adapter format (separate `zc`
  adapter — correct per vLLM's `check_unexpected_modules` allowlist — loads clean but inert; the fused-key
  rekey is rejected). The #47640 None-group guard-patch overlay did NOT fix it (failure is UPSTREAM of
  `expand_packed_lora` — the separate→fused mapping never happens). Fix PR #47640 is OPEN (unmerged) so no
  version-bump helps. Merge bakes deltas in (bypasses this) but is static.
