 Rubik's Cube AI Bot Challenge
============================================================

Challenge Page: http://127.0.0.1:9810/rubik_cube/challenge

Your goal: restore the scrambled Rubik's cube to its solved
state by calling the API endpoints below.

IMPORTANT: Only the current STATE is provided.  The scramble
sequence and move history are intentionally hidden.  You must
compute your own solution from the current state alone.

============================================================
 API Endpoints (base: http://127.0.0.1:9810)
============================================================

1. Get Current Cube State
   POST http://127.0.0.1:9810/rubik_cube/api/cube/state
   Content-Type: application/json
   Body: {"instance_id": "INSTANCE_ID"}

2. Single Move (step by step)
   POST http://127.0.0.1:9810/rubik_cube/api/cube/rotate
   Content-Type: application/json
   Body: {"instance_id": "INSTANCE_ID", "move": "R"}

3. Batch Execute (all moves at once)
   POST http://127.0.0.1:9810/rubik_cube/api/cube/exec
   Content-Type: application/json
   Body: {"instance_id": "INSTANCE_ID", "sequence": "R U R' U'"}

============================================================
 Move Notation
============================================================

Faces:
  U = Up    (white)
  D = Down  (yellow)
  F = Front (green)
  B = Back  (blue)
  L = Left  (orange)
  R = Right (red)

Suffixes:
  (none) = 90 deg clockwise
  '      = 90 deg counter-clockwise
  2      = 180 deg

Examples: R, U', F2, L, B', D2

============================================================
 Response Format
============================================================

All API responses are JSON:
{
  "ok": true/false,
  "state": {...},
  "solved": true/false,
  ...
}

When "solved" is true, you have restored the cube!
