+> **API-only.** This repository is the official Model Card & Documentation Hub for the `stealth-skeleton/skeleton-flash` endpoint on OpenRouter. It does **not** contain downloadable model weights. The Apache-2.0 license applies to the documentation and configuration files in this repository.
+
+**Low-Latency Vectorless Hierarchical PageIndex Tree RAG & High-Throughput Synthesis Engine**
+
+The speed specialist: retrieval over a hierarchical page-index tree instead of a vector store, plus high-throughput synthesis.
+
+## ✨ What it does
+
+- **Vectorless hierarchical PageIndex tree RAG**: navigate the document tree, no embeddings needed.
+- **Low latency** for interactive use.
+- **High-throughput synthesis** for summarizing and combining many sources.
+
+## 🧾 Quick facts
+
+| Property | Value |
+|---|---|
+| Interface | OpenAI-compatible Chat Completions |
+| Pricing | See the OpenRouter listing |
+| Weights | None: API-only |
+
+## 🔬 Under the hood
+
+- **Execution-verified mathematical operator synthesis**: generated operators are checked by running them.
+- **Sinkhorn-Knopp optimal transport**: L1 marginal residual 1.39e-16 at 40 iterations, epsilon = 0.15.
+- **Frisch-Waugh-Lovell (FWL) orthogonal projection**: residual < 1e-15.
+- **Romano Conformalized Quantile Regression (CQR)**: 90.35% empirical out-of-sample coverage, 0.2337 Normal CRPS.
+- **36th-order Hou-Li spectral filtering**.
+- **Auto-Exacto tool-calling grammar healing**: malformed tool-call JSON is repaired before it is returned.
+
+All figures above are self-reported from internal tests.
+
+## 📊 Benchmarks: Internal 3-Pass Evaluation Suite (Self-Reported)
+
+These results come from our internal 3-pass evaluation suite. They have not been independently verified and may differ from official leaderboard runs.
+
+| Suite | Score |
+|---|---|
+| MATH-500 | 92.00% |
+| GSM8K | 96.00% |
+| HumanEval | 92.00% |
+| GPQA-Diamond | 73.33% |
+| MMLU-Pro | 86.00% |
+| Arena-Hard | 85.00% |
+| ForecastBench (Proper Brier Skill) | 78.52% (0.0969 Brier) |
+| **Composite (mean of 7)** | **86.12 / 100** |
