+# IOAI 2026 — Find the Order
+
+Official contest data for **Find the Order**, task 1 (Day 1) of the [IOAI 2026](https://ioai-official.org) Individual Contest, held in Astana, Kazakhstan.
+
+Spoken English dialogues are segmented into speaker turns, one `.wav` per turn, and shuffled. Contestants reconstruct the original turn order. `prefix.json` in each dialogue folder gives the first two chunk indexes, fixing the reading direction.
+
+The task statement, translations, baseline and grader live in the [IOAI-2026 GitHub repository](https://github.com/IOAI-official/IOAI-2026/tree/main/Individual-Contest/1_Find_the_Order). This repository holds **data only**.
+
+## Subsets
+
+| Subset | Path | Contestants saw it | Role |
+|---|---|---|---|
+| Public – train | `public/train/` + `public/train_answers.json` | yes | labelled dialogues |
+| Public – dry-run | `public/pretrain/`, `public/pretest/` + answers | yes | 20-dialogue slices for pipeline validation |
+| Private – Leaderboard A | `private/test_leaderboard_a/` + `private/test_leaderboard_a_answers.json` | no | **live leaderboard** during the contest |
+| Private – Leaderboard B | `private/test_leaderboard_b/` + `private/test_leaderboard_b_answers.json` | no | **final ranking** |
+
+Audio: mono, 44.1 kHz; 7–20 chunks per dialogue. Answers files sit at the subset root, matching the contest grader's layout.
+
+> ⚠️ **The `private/` subset contains the graded splits and their answer keys.** Published for post-contest study; the task cannot be reused for competition.
