 1. Keep non-fused as the strict safety baseline, and use `LLAMA_QWEN3NEXT_FUSED_DELTA=1` (prefill-only fused) as the practical acceleration mode.
 2. Port selective graph-shape optimizations from PR #19375 into `src/llama-build-context.cpp` where they map cleanly (avoid blind copy due architectural divergence).

+3. Added dedicated Qwen3Next regression target for dev/CI-style checks:

 4. Investigate ik CPU Flash-Attn assertion path for Qwen3Next (`iqk_fa_templates.h`, `S > 0`) before enabling `-fa 1` for CPU benchmark profiles.

   - Results are surfaced in `SUMMARY.md` under `IK Fused Delta Regression`.
 - Fused regression now enforces absolute non-fused sanity too:
   - mode0 decode/prefill PPL must stay below configurable thresholds (defaults: `10.0` / `10.0`).
