# Verification of ExtractionResult Struct Fields

## Task: bf-5gjeo

## Finding

The bead description refers to verifying an "ExtractionResult struct" with fields:
- exit_code: Option<i32>
- stdout: String
- stderr: String
- success: bool

However, after searching the codebase, I found that the relevant struct is actually **`TestExecutionResult`** (not `ExtractionResult`) located at `/home/coding/pdftract/tests/encryption_fixtures.rs:189`.

## TestExecutionResult Structure

**Location:** `tests/encryption_fixtures.rs:189`

**Implementation:**
```rust
#[derive(Debug, Clone)]
pub struct TestExecutionResult {
    /// The underlying process output
    pub output: std::process::Output,
    /// Optional fixture name for better error messages
    pub fixture_name: Option<String>,
}
```

The struct wraps `std::process::Output` and provides methods to access the data:

### Core Methods (equivalent to the required fields)
- `exit_code() -> Option<i32>` - Line 214
- `stdout() -> String` - Line 218
- `stderr() -> String` - Line 223
- `success() -> bool` - Line 229

### Assertion Methods Available
- `assert_stderr_contains(&str)` - Line 243
- `assert_stdout_contains(&str)` - Line 255
- `assert_exit_code(i32)` - Line 267
- `assert_success()` - Line 282
- `assert_failure()` - Line 294
- `assert_output_contains(&str)` - Line 306
- `assert_unsupported_encryption()` - Line 326
- `assert_password_required()` - Line 351

## Other Related Structs Found

1. **`ExtractionResult`** (`crates/pdftract-core/src/extract.rs:237`) - Main PDF extraction result struct with fields: fingerprint, pages, metadata, signatures, form_fields, links, attachments, threads, javascript_actions. Not related to CLI testing.

2. **`TestResult`** (`crates/pdftract-core/tests/TH-03-mcp-no-auth.rs:25`) - TH-03 specific test result with direct fields: passed, exit_code, stderr, stdout, bound_port.

## Acceptance Criteria Verification

- ✓ Struct exists with accessors for all 4 required values (via methods)
- ✓ Field types are appropriate:
  - exit_code: Option<i32> ✓
  - stdout: String ✓
  - stderr: String ✓
  - success: bool ✓
- ✓ Struct derives Debug for helpful test output ✓ (line 188)
- ✓ Location documented: `tests/encryption_fixtures.rs:189`

## Naming Discrepancy Note

The bead and parent bead (bf-4wbf2) refer to "ExtractionResult struct" in the context of encryption test validation, but the actual struct that implements the assertion methods is `TestExecutionResult`. This appears to be a documentation/terminology discrepancy in the bead chain rather than a missing struct.
