+# SLaNg Dataset Report
+
+## 1. Dataset Scale
+- **Total Records:** 100,000 unique calculus strings.
+- **Data Splits:** 90% Train (90,000), 5% Val (5,000), 5% Test (5,000).
+
+## 2. Rule Coverage
+- Handles 4 types of mathematical derivation rules: Power rule, Trig derivative, Exponential rule, and Logarithmic rule.
+
+## 3. Limitations & Gaps
+- Currently uses 6 hardcoded templates. Only supports basic integers.

+# SLaNg Dataset Schema Definitions
+
+Each entry in the `.jsonl` files contains the following keys:
+- `src_tokens`: Character level source math input.
+- `src_positions`: Positional tracking list.
+- `tgt_input_tokens`: Shifted target input tokens for decoder forcing.
+- `tgt_output_tokens`: Target labels for structural output generation.
+- `rule_ids`: Multi-head classification integer targeting math rules.
+- `verification_state`: Binary flag (1 for true derivations, 0 for false steps).
+- `text`: String log containing complete equation block text.
