feat(datagen): add dataset generation CLI with sharding and checkpointing
...
CI / lint (push) Has been cancelled
CI / type-check (push) Has been cancelled
CI / test (push) Has been cancelled
- Add solver/datagen/dataset.py with DatasetConfig, DatasetGenerator,
ShardSpec/ShardResult dataclasses, parallel shard generation via
ProcessPoolExecutor, checkpoint/resume support, index and stats output
- Add scripts/generate_synthetic.py CLI entry point with Hydra-first
and argparse fallback modes
- Add minimal YAML parser (parse_simple_yaml) for config loading
without PyYAML dependency
- Add progress display with tqdm fallback to print-based ETA
- Update configs/dataset/synthetic.yaml with shard_size, checkpoint_every
- Update solver/datagen/__init__.py with DatasetConfig, DatasetGenerator
exports
- Add tests/datagen/test_dataset.py with 28 tests covering config,
YAML parsing, seed derivation, end-to-end generation, resume,
stats/index structure, determinism, and CLI integration
Closes #10

feat: ground truth labeling pipeline
...
CI / lint (push) Failing after 25m6s
CI / type-check (push) Has been cancelled
CI / test (push) Has been cancelled
- Create solver/datagen/labeling.py with label_assembly() function
- Add dataclasses: ConstraintLabel, JointLabel, BodyDofLabel,
AssemblyLabel, AssemblyLabels
- Per-constraint labels: pebble_independent + jacobian_independent
- Per-joint labels: aggregated independent/redundant/total counts
- Per-body DOF: translational + rotational from nullspace projection
- Assembly label: classification, total_dof, has_degeneracy flag
- AssemblyLabels.to_dict() for JSON-serializable output
- Integrate into generate_training_batch (adds 'labels' field)
- Export AssemblyLabels and label_assembly from datagen package
- Add 25 labeling tests + 1 batch structure test (184 total)
Closes #9

- Add random body orientations via scipy.spatial.transform.Rotation
- Add parallel axis injection with configurable probability
- Add grounded parameter on all 7 generators (grounded/floating)
- Add axis sampling strategies: cardinal, random, near-parallel
- Update _create_joint with orientation-aware anchor offsets
- Add _resolve_axis helper for parallel axis propagation
- Update generate_training_batch with axis_strategy, parallel_axis_prob,
grounded_ratio parameters
- Add body_orientations and grounded fields to batch output
- Export AxisStrategy from datagen package
- Add 28 new tests (72 total generator tests, 158 total)

feat: parameterized assembly templates and complexity tiers
...
CI / lint (push) Has been cancelled
CI / type-check (push) Has been cancelled
CI / test (push) Has been cancelled
Add 4 new topology generators to SyntheticAssemblyGenerator:
- generate_tree_assembly: random spanning tree with configurable branching
- generate_loop_assembly: closed ring producing overconstrained data
- generate_star_assembly: hub-and-spoke topology
- generate_mixed_assembly: tree + loops with configurable edge density
Each accepts joint_types as JointType | list[JointType] for per-joint
type sampling.
Add complexity tiers (simple/medium/complex) with predefined body count
ranges via COMPLEXITY_RANGES dict and ComplexityTier type alias.
Update generate_training_batch with 7-way generator selection,
complexity_tier parameter, and generator_type field in output dicts.
Extract private helpers (_random_position, _random_axis,
_select_joint_type, _create_joint) to reduce duplication.
44 generator tests, 130 total — all passing.
Closes #7

test: add unit tests for datagen modules

- test_types.py: JointType enum values/count, dataclass defaults/isolation
- test_pebble_game.py: DOF accounting, rigidity, classification, edge results
- test_jacobian.py: Jacobian shape per joint type, rank, parallel axis degeneracy
- test_analysis.py: demo scenarios (revolute, fixed, triangle, parallel axes)
- test_generator.py: chain/rigid/overconstrained generation, training batch
Bug fixes found during testing:
- JointType enum: duplicate int values caused aliasing (SLIDER=REVOLUTE etc).
Changed to (ordinal, dof) tuple values with a .dof property.
- pebble_game.py: .value -> .dof for constraint count
- analysis.py: classify from effective DOF (not raw pebble game with virtual
ground body skew)
105 tests, all passing.
Closes #6
