## Example Entry
An entry in the miniCTX dataset consists of the theorem statement, preceding file contents, and metadata information. For example, given the following theorem `s_eq_pow_two` in context:

```lean
import Mathlib.Data.Real.Basic

/-!
# Square function
We define the squaring function `s : ℝ → ℝ` to be `s x := x * x`.
-/

def s (x : ℝ) : ℝ := x * x

lemma s_eq_pow_two {x : ℝ} : s x = x ^ 2 := by
  rw [s, pow_two]
```

The problem is formatted in JSON as follows:

```json
{
  # Preceding file content
  "srcContext": "import Mathlib.Data.Real.Basic\n\n/-!\n# Square function\nWe define the squaring function `s : ℝ → ℝ` to be `s x := x * x`.\n-/\n\ndef s (x : ℝ) : ℝ := x * x\n\n",
  
  # Theorem statement
  "theoremStatement": "lemma s_eq_pow_two {x : ℝ} : s x = x ^ 2",

  # Fully qualified theorem name
  "theoremName": "s_eq_pow_two",

  # Temporal metadata

  "theoremCreated": {"commit":"(git commit)", "date":"(date the commit is updated)"},

    # Number of tokens before the theorem
    "tokenPositionInFile": 152,
    # Number of premises (definitions, theorems) before the theorem
    "theoremPositionInFile": 1
  },

    # Number of definitions or lemmas defined in this repository that the theorem uses (including in-file ones)

    # Number of total premises (in file, repository, or otherwise)
    "numPremises": 2,
    # Modules imported in the current file
    "importedModules": ["Mathlib.Data.Real.Basic", ...]
  },

```

### Description of Each Entry

- **srcContext**: The context of the source file preceding the theorem, including imports and relevant definitions. This provides necessary background to understand the theorem.
- **theoremStatement**: The statement of the theorem being proved.
- **theoremName**: The name of the theorem.
- **fileCreated**: The git commit hash indicating when the file was created.
- **theoremCreated**: The git commit hash indicating when the theorem was added.
- **file**: The name of the file containing the theorem.
- **positionMetadata**:
  - **lineInFile**: The line number in the file where the theorem is located.
  - **tokenPositionInFile**: The number of tokens in the file before the theorem starts.
  - **theoremPositionInFile**: The number of premises (definitions, theorems) before the theorem in the file.
- **dependencyMetadata**:
  - **inFilePremises**: Indicates whether the theorem uses definitions or lemmas defined in the same file.
  - **numInFilePremises**: The number of definitions or lemmas from the same file that the theorem relies on.
  - **repositoryPremises**: Indicates whether the theorem uses definitions or lemmas defined in another file within the same repository.
  - **numRepositoryPremises**: The total number of definitions or lemmas from the repository (including the current file) that the theorem depends on.
  - **numPremises**: The total number of premises the theorem depends on, regardless of whether they are from the same file, the repository, or external sources.
  - **importedModules**: Lists the modules imported in the current file. 
- **proofMetadata**:
  - **hasProof**: Indicates whether the theorem has a proof.
  - **proof**: The proof of the theorem.
  - **proofType**: The type of proof, term proof or tactic proof.
  - **proofLengthLines**: The length of the proof in lines.
  - **proofLengthTokens**: The length of the proof in tokens.
