📁 Dataset Variants

1. `preprocess-CodeContests-perturbation-none`

No perturbation applied
Pure clean programs
Used as baseline reference

2. `preprocess-CodeContests-perturbation-syntax`

Only syntax-level perturbations
Bug types: token deletion, indentation errors, malformed expressions
Focus: syntax recovery ability

3. `preprocess-CodeContests-perturbation-structure`

Only structure-level perturbations
Bug types: line swap, line deletion, statement reordering
Focus: program structure repair

4. `preprocess-CodeContests-perturbation-semantic`

Only semantic-level perturbations
Bug types: logic errors, wrong operators, boundary mistakes
Focus: semantic reasoning repair

5. `preprocess-CodeContests-perturbation-mix`

Mixed perturbation dataset
Combines syntax + structure + semantic corruption
Used for general robustness training

6. `preprocess-CodeContests-perturbation-mixed-task-*`

These are controlled mixture ratio subsets used for ablation and scaling.

Format:

00100 → 0 : 10 : 0 : 0
01000 → 0 : 0 : 10 : 0
10000 → 10 : 0 : 0 : 0
2242  → 2 : 2 : 4 : 2

Where the order is:

[syntax : structure : semantic : mixed]

Examples:

00100 → only structure perturbation (100%)
01000 → only semantic perturbation (100%)
10000 → only syntax perturbation (100%)
2242 → balanced mixture (2:2:4:2)
