The S Mazes and the M1 Mazes with Their Tests

[helenlu66]

Summary

Moves the S maze set and the M1 single key-door maze set from inside the ogbench submodule into the root repo along with maze-specific tests and rendered maze images.

Maze Sets

S1: 8x8 empty room, no mechanisms - Baseline, can model navigate at all? Also validates environment

S2: 8x8 corridor with turns, no mechanisms - Does turning matter?

S3: 10x10 corridor with turns, no mechanisms - Moderate size navigation

S4: 10x10 dense maze (dead ends), no mechanisms - Does topology matter at moderate size?

S5: 14x14 corridor with turns, no mechanisms - Large grid navigation

S6: 14x14 dense maze (dead ends), no mechanisms - Large grid + topology combined

M1: Single key-door - Basic mechanism comprehension example

Visualizing Mazes

python3 scripts/render_maze_jsons.py \
  --input-dir mazes/exp_maze_jsons \
  --output-dir mazes/exp_maze_images

Maze-Specific Tests

From the repo root:

cd tests && python3 -m unittest test_S_maze_types.py test_M1_maze_types.py

Tests should all pass:

Pull request overview

This PR brings the S (S1–S6) and M1 (single key-door) maze JSON specifications into the root repository (out of the ogbench submodule), along with dedicated unit tests and supporting test helpers to validate maze structure and solvability.

Changes:

• Adds new maze-spec test suites for S mazes and M1 mazes, plus shared maze test utilities.
• Introduces a test-helper BFS solver wrapper that delegates planning to the existing gridworld baseline planner.
• Adds the S/M1 experimental maze JSONs under mazes/exp_maze_jsons/, plus editor and submodule metadata files.
