-Decision: Phase41 confirms D1 remains relevant for low-concurrency/latency work, but the measured current-stack gap is around `0.75x` vLLM at `n=1/8` and `0.665x` at `n=32`, not an immediate parity bridge. TTFT remains the larger user-visible gap.
+Decision: Phase41 confirms a low-concurrency/latency gap, but it does not reopen D1/full-step graph capture. Patch `0043` already ships grouped-MMQ full-step graph capture default-on, and Phase34 found `host_sync=0/4096`. The measured current-stack gap is around `0.75x` vLLM at `n=1/8` and `0.665x` at `n=32`; TTFT remains the larger user-visible gap.

+# Target Reconciliation Phase42 Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Reconcile the post-Phase41 target list so the next parity phase does not chase a closed D1/GDN/W4A16 premise.
+
+**Architecture:** Use read-only parallel subagent analysis over D1 graph capture, GDN prefill, and W4A16/MoE prefill GEMM. Record the resulting target decision in the parity docs.
+
+**Tech Stack:** LocalAI docs, llama.cpp patch mirrors, `/home/mudler/_git/llama.cpp` fork, Git.

+- Read: `backend/cpp/llama-cpp-localai-paged/patches/paged/0050-*.patch`
+
+- [x] **Step 1: Review D1**
+
+Ask a read-only explorer to reconcile whether D1/full-step graph capture is shipped or still open.
+
+Observed:
+
+```text
+D1/full-step MoE decode CUDA graph capture is shipped and default-on.
+The host-sync premise is closed/refuted for current GB10 NVFP4 grouped-MMQ decode.
+```
+
+- [x] **Step 2: Review GDN**
+
+Ask a read-only explorer to inspect GDN tensor-core/chunking state.
+
+Observed:
+
+```text
+0046/0047 are shipped GB10 wins.
+0031 scalar chunking stayed opt-in/slower.
+C32 slab, QS-early, and Global-Ai32 were correctness-clean but slower.
+Do not add another GDN GB10 patch.
+```
+
+- [x] **Step 3: Review W4A16/GEMM**
+
+Ask a read-only explorer to inspect the prefill GEMM / W4A16 state.
+
+Observed:
+
+```text
+0033/0034/0035 are default-off.
+0048/0049/0050 improve forced W4A16 only marginally.
+Production defaults still use FP4-MMQ.
+Do not add another small W4A16 body/metadata patch.

+
+- [x] **Step 1: Correct Phase41 D1 wording**

+- [x] **Step 2: Add Phase42 decision**
+
+Record:
+
+```text
+D1: closed on current GB10 path.
+GDN: low-conflict GB10 work exhausted.
+W4A16/GEMM: micro-patch track exhausted.
+Next small GB10 source candidate: persistent/load-time F32 combined gate projection.
