+# Bestemshe Table Base — Strong Solution Proof
+
+**Authors:** Ansar Zeinulla & Murat Manassov  
+**Affiliation:** Nazarbayev University, Kazakhstan  
+**Code Repository:** [github.com/ansarzeinulla/Bestemshe](https://github.com/ansarzeinulla/Bestemshe)  
+**Live Interactive Explorer:** [huggingface.co/spaces/ansarzeinulla/Bestemshe-God-Algorithm](https://huggingface.co/spaces/ansarzeinulla/bestemshe-god-algorithm)
+
+Bestemshe is a traditional Kazakh two-player mancala-style game (5 pits per player, 50 total stones). This artifact is a **strong solution** of the game: for every reachable, legal position the exact game-theoretic value (win / draw for the side to move) has been computed by retrograde analysis and stored, enabling perfect play via direct $O(1)$ memory-mapped lookup without runtime search. 
+
+Together with the solver that produced it, this tablebase constitutes a machine-verifiable proof of the game's outcome under optimal play: **a forced win for the second player (Follower)**.
+
+---
+
+## Game Encoding
+
+A position is described by the two Kazans (captured-stone stores) `K1` (side to move) and `K2` (opponent), and ten pits of `0..N` stones. The 50 stones are conserved:
+$$\sum_{i=1}^{10} \text{pits}[i] + K_1 + K_2 = 50$$
+
+Captures are strictly even, so each Kazan score is an even integer. A Kazan reaching $\ge 26$ decides the game immediately and lies outside the stored range ($0 \le K_1, K_2 \le 24$). Positions are stored canonically from the **side-to-move** perspective.
+
+---
+
+## Layer Layout
+
+The tablebase is sharded into **layers indexed by the Kazan pair `(K1, K2)`**, where each Kazan is even in $0..24$ ($13 \times 13 = 169$ pairs). Every pair consists of two Zstandard-compressed bitset files:
+
+- `layer_<K1>_<K2>_win.bin.zst` — The WIN/LOSS bitset for that layer.
+- `layer_<K1>_<K2>_draw.bin.zst` — The DRAW bitset for that layer.
+
+Files are Zstandard-compressed bitsets indexed by a combinatorial ranking of the pit configuration (`StateIndex`).
+
+---
+
+## Summary Statistics
+
+| Metric | Value |
+| :--- | :--- |
+| **Layer pairs `(K1, K2)`** | 169 |
+| **Total files** | 338 (169 win + 169 draw) |
+| **WIN files total size** | 6.0 GB |
+| **DRAW files total size** | 2.4 GB |
+| **Grand Total Size** | **8.3 GB** (8,962,782,421 bytes) |
+
+---
+
+## How to Query (Quickstart)
+
+```python
+import zstandard as zstd
+
+# Example: Loading a specific layer in Python
+def load_layer(k1, k2, result_type="win"):
+    filename = f"data/layer_{k1}_{k2}_{result_type}.bin.zst"
+    with open(filename, 'rb') as fh:
+        dctx = zstd.ZstdDecompressor()
+        decompressed_data = dctx.decompress(fh.read())
+    return decompressed_data
+
+# Query bit at index
+def is_winning_state(decompressed_bytes, state_index):
+    byte_idx = state_index // 8
+    bit_idx = state_index % 8
+    return bool((decompressed_bytes[byte_idx] >> bit_idx) & 1)
+```

+# Deployment Guide
+
+Two targets, two strategies (GitHub's free LFS tier is only 1GB, so the 8.3GB
+tablebase goes to Hugging Face only):
+
+| Target | Contents |
+|---|---|
+| GitHub | Code only — `layers/` stays gitignored |
+| HF Space | Code + Dockerfile + `layers/compressed` (8.3GB, LFS) |
+
+## 1. GitHub (code-only)
+
+```bash
+git add -A
+git commit -m "Restructure: promote New/ to root, add Tablebase Explorer"
+git remote add origin git@github.com:<you>/Bestemshe.git
+git push -u origin audit-optimize-harden   # or merge to main first
+```
+
+Nothing under `layers/` is committed (see `.gitignore`), so no LFS needed on GitHub.
+
+## 2. Hugging Face Space
+
+The Space `ansarzeinulla/Bestemshe-God-Algorithm` already exists as a free **Gradio SDK**
+space (Docker Spaces require a PRO subscription; Gradio ones are free). The C++ CLI is
+compiled at app startup — `packages.txt` installs g++/make/libzstd-dev via apt, and
+`app.py` builds `./query` on first launch. Do NOT upload the Dockerfile or a README
+with `sdk: docker` — that converts the Space to Docker and triggers a 402.
+
+```bash
+pip install -U "huggingface_hub[cli]"
+hf auth login    # the CLI is `hf` (huggingface-cli is deprecated)
+```
+
+### Option A (recommended): HfApi.upload_folder
+
+NOTE: `hf upload` fails with `402 Payment Required` on free-tier Gradio Spaces because
+the CLI always hits the `repos/create` endpoint first (even for existing repos). The
+Python API commits directly to the existing repo and works. Run from the repo root:
+
+```python
+from huggingface_hub import HfApi
+api = HfApi()
+
+# Code
+api.upload_folder(
+    repo_id="ansarzeinulla/Bestemshe-God-Algorithm", repo_type="space",
+    folder_path=".",
+    allow_patterns=["app.py", "requirements.txt", "packages.txt", "query.cpp",
+                    "Oracle.h", "StateIndex.h", "BestemsheCore.h", ".gitattributes", "README.md"],
+)
+
+# Tablebase (8.3GB, LFS automatically)
+api.upload_folder(
+    repo_id="ansarzeinulla/Bestemshe-God-Algorithm", repo_type="space",
+    folder_path="layers/compressed", path_in_repo="layers/compressed",
+)
+```
+
+This uploads code + `layers/compressed` (large files automatically stored as LFS
+server-side). Resumable if the 8.3GB transfer drops. The Space then builds the
+Dockerfile and serves the Gradio app on port 7860.
+
+### Option B: pure git-lfs push
+
+```bash
+git clone https://huggingface.co/spaces/ansarzeinulla/Bestemshe-God-Algorithm hf-space
+cd hf-space
+git lfs install
+cp -R ../{app.py,requirements.txt,Dockerfile,README.md,.gitattributes,query.cpp,Oracle.h,StateIndex.h,BestemsheCore.h} .
+mkdir -p layers && cp -R ../layers/compressed layers/compressed
+# IMPORTANT: do NOT copy the repo .gitignore into the HF clone — it ignores layers/.
+git add -A
+git commit -m "Bestemshe Tablebase Explorer"
+git push   # pushes 8.3GB via LFS; expect it to take a while
+```
+
+`.gitattributes` already routes `layers/compressed/*.bin` through LFS.
+
+## Notes
+
+- The Docker image COPYs the tablebase into the image; first build takes a while
+  but queries never load more than one 4MB block into RAM.
+- To test the container locally: `docker build -t bestemshe . && docker run -p 7860:7860 bestemshe`.

+# Bestemshe — Strongly Solved
+
+Bestemshe is a Mancala variant (2×5 pits, 2 kazans, 50 stones). This repo contains
+the HPC retrograde solver that strongly solved the game, the resulting ~8.3GB
+zstd-compressed endgame tablebase, and a **Tablebase Explorer** web UI.
+
+**Game-theoretic value of the starting position: the first player LOSES with perfect play.**
+
+## Components
+
+| File | Purpose |
+|---|---|
+| `main.cpp`, `Solver.{h,cpp}`, `Compressor.{h,cpp}`, `Inference.h` | HPC solver / verifier / compressor (`./bestemshe`) |
+| `Oracle.h`, `query.cpp` | Explorer CLI: mmap + single-block zstd decode, ~20MB RSS per query (`./query`) |
+| `app.py` | Gradio UI (calls `./query` via subprocess) |
+| `layers/compressed/` | Tablebase: `layer_<K1>_<K2>_{win,draw}.bin` (not in the GitHub repo; LFS on the HF Space) |
+
+## Build & run locally
+
+```bash
+brew install zstd libomp   # macOS prerequisites (Linux: apt install libzstd-dev)
+make            # solver: ./bestemshe
+make query      # explorer CLI: ./query
+./query 0 0 5 5 5 5 5 5 5 5 5 5   # JSON eval of the start position
+pip install -r requirements.txt
+python app.py   # http://localhost:7860
+```
+
+Position format: 12 integers `K1 K2 p0..p9`, side-to-move perspective
+(K1/p0–p4 = mover). Stones total 50; kazans are even. Evaluations are exact
+Win/Draw/Loss (the tablebase stores no mate distances).
+
+Set `BESTEMSHE_DATA_DIR` to point at the compressed layers (default `layers/compressed`).
+
+## How the 10GB lookup stays OOM-safe
+
+Each `.bin` stores a header `[u32 num_blocks][u32 offsets[]]` followed by
+independently zstd-compressed 4MB blocks. `Oracle.h` mmaps the file (zero-copy,
+pages faulted on demand), reads the offset table in place, and decompresses only
+the one block containing the queried state's bit — peak RSS stays ~20MB
+regardless of tablebase size, well inside the free HF Space's 16GB.
+
+See [DEPLOY.md](DEPLOY.md) for pushing to GitHub (code-only) and the Hugging Face Space (with data).

+# Format: ./bestemshe --verify-pair <M> <K1> <K2>
+# Example:
+./bestemshe --verify-pair 10 2 8
+
+# This does a local lock-free forward sweep to ensure the generated .raw files
+# are 100% mathematically consistent. If this fails, the node corrupted the data.
+
+
+# ------------------------------------------------------------------------------
+# STEP 3: COMPRESS THE PAIR (ZSTD LEVEL 19)
+# ------------------------------------------------------------------------------
+# Format: ./bestemshe --compress <input.raw> <output.bin>
+# Note: Block size and Algorithm are hardcoded now, no extra args needed.
+
+./bestemshe --compress layers/layer_2_8_win.raw layers/compressed/layer_2_8_win.bin
+./bestemshe --compress layers/layer_2_8_draw.raw layers/compressed/layer_2_8_draw.bin
+
+
+# ------------------------------------------------------------------------------
+# STEP 4: CLEANUP RAW FILES TO SAVE SSD SPACE
+# ------------------------------------------------------------------------------
+# Once compression is complete and verified, delete the raw files on the node.
+rm layers/layer_2_8_win.raw
+rm layers/layer_2_8_draw.raw
+
+
+# ------------------------------------------------------------------------------
+# ENDGAME: THE GOD QUERY
+# ------------------------------------------------------------------------------
+# When you finally solve M=0 (K1=0, K2=0), run:
+./bestemshe --root
+
+# This will load layer_0_0 and output the absolute game-theoretic truth of Bestemshe.
