+# Hexo Human Corpus
+
+Encoding-free corpus of **6,902** decisive human *Hex Tac Toe* games — hexagonal
+grid, six-in-a-row to win (player 1 opens with 1 move, then both players play 2
+moves per turn; the board is theoretically infinite).
+
+Each line is one game as a **raw axial move list + outcome**. Nothing about any
+neural-network encoding is baked in — no planes, no fixed board size, no action
+space. Read it with the stdlib `json` module and build whatever representation
+you want.
+
+## Files
+
+| file | description |
+|------|-------------|
+| `hexo_human_corpus.jsonl` | the corpus — one game per line |
+| `SCHEMA.md` | full per-line schema + conventions |
+| `dataset_metadata.json` | provenance: counts, sha256, source filter |
+
+## Schema
+
+One JSON object per line:
+
+```json
+{"game_hash":"0f8c6bdfc55e7f6f","moves":[[0,0],[2,-2],[-3,3]],"winner":1,"source":"human","elo":[898,955]}
+```
+
+| field | type | meaning |
+|-------|------|---------|
+| `game_hash` | string (16 hex) | SHA-256 of the move sequence — stable content/dedup key |
+| `moves` | array of `[x, y]` | axial hex coords `(x,y)=(q,r)`, in play order |
+| `winner` | `1` or `-1` | `1` = first player (X) wins, `-1` = second player (O) |
+| `source` | string | `"human"` |
+| `elo` | `[int\|null, int\|null]` | `[elo_p1, elo_p2]` |
+
+**Conventions**
+
+- Axial hex coordinates `(x, y)`; the board is infinite so values can be
+  negative. The first player's forced opener is always `(0, 0)`.
+- Replay `moves` in order to reconstruct any board state.
+- Only decisive (six-in-a-row) games are included — there are **no draws**.
+
+## Usage
+
+```python
+import json
+
+games = [json.loads(line) for line in open("hexo_human_corpus.jsonl")]
+print(len(games), "games")          # 6902
+g = games[0]
+print(g["moves"], g["winner"])      # [[0,0], [2,-2], ...]  1
+```
+
+## Provenance
+
+Rated human games filtered to: rated, ≥20 moves, decisive by six-in-a-row.
+Per-game `elo` is each player's rating at game time. Games are anonymised
+(player ids dropped; only relative Elo retained). See `dataset_metadata.json`
+for the exact sha256 and counts.

+# Hexo human corpus — JSONL schema
+
+Encoding-free export of scraped Hex Tac Toe human games. One JSON object per
+line, readable with the stdlib `json` module — no numpy, no game engine, no
+encoding dependency.
+
+## Per-line object
+
+| field       | type            | meaning |
+|-------------|-----------------|---------|
+| `game_hash` | string (16 hex) | SHA-256 of the move sequence; dedup key, stable across sources |
+| `moves`     | array of `[x,y]` | axial hex coords, in play order |
+| `winner`    | `1` or `-1`     | `1` = first player (X) wins, `-1` = second player (O) |
+| `source`    | string          | always `"human"` for this dataset |
+| `elo`       | `[int or null, int or null]` | `[elo_p1, elo_p2]`; absent when exported with `--no-meta` |
+
+`game_hash` is the canonical content hash used across the corpus pipeline, so
+the same game scraped twice — or appearing in another source — collapses to one
+key. Exact duplicates are dropped on export (`n_duplicates_dropped` in
+`dataset_metadata.json`).
+
+## Conventions
+
+- **Coordinate system:** axial hex `(x, y) == (q, r)`. The board is
+  theoretically infinite; coordinates can be negative. The first player's
+  forced opening move is always `(0, 0)`.
+- **Move order:** `moves[0]` is the first player's opener, then players
+  alternate per the game's turn structure (P1 opens with 1 move, then both
+  sides play 2 moves per turn). Reconstruct board state by replaying in order.
+- **Winner:** engine convention — `1` = first mover (X), `-1` = second (O).
+  Only decisive (six-in-a-row) games are included; there are no draws.
+
+## Provenance
+
+- games: **6902**
+- sha256 (`hexo_human_corpus.jsonl`): `54fae7aebcef2a9d19d13c1946fae36c0565e21bc726c25e2e4e230cfb42a5b7`
+- source filter: rated, >=20 moves, decisive by six-in-a-row
