+## Key Innovation
+
+A single-knob improvement on top of [@clarkkev's PR #1394](https://github.com/openai/parameter-golf/pull/1394) sp8192 baseline + a legal score-first TTT eval pass:
+
+1. **QK_GAIN_INIT = 5.0** (vs PR #1394's 4.0) — raised attention query/key scaling on the same arch.
+2. **Legal score-first TTT** — score each sliding window chunk under `inference_mode()` BEFORE any gradient update; each chunk is only trained on after it has been fully scored. No chunk is trained on before scoring.
+
+```python
+for chunk_idx, chunk_windows in enumerate(chunks):
+    # Phase 1: SCORE (no grad, no model update)
+    with torch.inference_mode():
+        nll = model.forward_logits(batch).cross_entropy(targets)
+    loss_sum += nll.sum()
+
+    # Phase 2: TRAIN (only on the chunk just scored, never on anything still-to-score)
+    if not is_last_chunk:
+        for _ in range(ttt_epochs):
+            for x, y in chunk_seqs:
+                loss = model(x, y)
+                loss.backward()
+                optimizer.step()
+```
+
+Strict score-before-update ordering matches the PR #549 precedent and satisfies [Issue #1017](https://github.com/openai/parameter-golf/issues/1017) conditions 1–4. No eval-time delta optimization (no SLOT), no pre-quant TTT on val data, no two-pass rescoring, no n-gram cache.
+
+## Changes from baseline (PR #1394)
+
+| Component | PR #1394 | This PR |
+|---|---|---|
+| Tokenizer | SentencePiece BPE 8192 | SentencePiece BPE 8192 (same) |
+| Architecture | 11L / 512d / 8H / 4KV, MLP 4x, Partial RoPE 16d | (same) |
+| Depth recurrence | Loop layers 4–5 twice from 50% training | (same) |
+| Optimizer | MuonEq-R (row-normalized Muon), WD=0.085 | (same) |
+| Quantization | GPTQ int6 matrices + int8 embeddings + SD-clip (matrix_clip_sigmas=12.85, embed_clip_sigmas=20.0) | (same) |
+| **QK_GAIN_INIT** | **4.0** | **5.0** |
+| **TTT** | **none** | **Legal score-first, LR=0.005, epochs=3, freeze=0** |
+| val_bpb (3-seed mean, sliding no-TTT) | 1.08563 | **1.08486** |
+| val_bpb (3-seed mean, post-TTT) | — | **1.08279** |
+| Δ vs PR #1394 baseline (nats/token) | — | **−0.00731** |
+
+## Architecture
+
+11L × 512d × 8H / 4KV, MLP 4×, LeakyReLU(0.5)² activation, Partial RoPE (16 / 64 dims), layerwise LN scale, tied token embeddings. Depth recurrence: encoder [0,1,2,3,4,5,4], decoder [5,4,5,6,7,8,9,10] (loops layers 4–5 twice, activated at step 2885 ≈ 50% training).
+
+Quantization: full-Hessian GPTQ on all attention/MLP matrices at int6 with SD-based clip (row_std × 12.85 / 31 step); token embedding at int8 with clip 20 × row_std; small control tensors and scalars kept float16/float32 via passthrough. Compression: byte-shuffle + Brotli-11. Self-extracting LZMA mini runner (~16.7 KB code).
+
+## Rule Compliance
+
+Per [repo README](https://github.com/openai/parameter-golf) and [Issue #1017](https://github.com/openai/parameter-golf/issues/1017) four conditions:
+
+- **Condition 1 (Causality)**: Strict causal forward pass. Sliding-window eval never references future tokens for current-position scoring.
+- **Condition 2 (Normalized distribution)**: Standard softmax over full vocab, no normalization trickery. No BigramHash, no two-pass rescoring, no logit biasing.
+- **Condition 3 (Score before update)**: Every TTT chunk is scored under `inference_mode()` BEFORE any parameter update. Gradient updates only use already-scored tokens. Score-first pattern matches merged precedent PR #549.
+- **Condition 4 (Single pass)**: Each token is scored exactly once. No rescoring, no cache lookups.
+
+Additional:
+- **No SLOT** (standard or causal). No eval-time delta optimization in hidden space.
+- **No pre-quant TTT on val data**. The model is quantized once after training, then evaluated.
+- **No ETLB** (eval-time logit bias).
+- **No n-gram cache** at eval.
+- **No tokenizer change** — uses PR #1394's SentencePiece BPE 8192 unchanged.
+- **Artifact under 16 MB** on all 3 seeds (margins 7,454–10,942 bytes).
+- **Training under 600s** on all 3 seeds (~588 s actual).
+- **Eval under 600s** on all 3 seeds (~382 s actual: 8 s roundtrip + 83 s sliding + 290 s TTT).
+- **3 distinct seeds** (0, 42, 1234) — independent runs on the same hardware.
