Here's a solution for parsing CSV rows with proper handling of quoted fields and escaped quotes:

```python
def parse_csv_row(line: str) -> list[str]:
    fields = []
    current_field = []
    in_quotes = False
    i = 0
    
    while i < len(line):
        char = line[i]
        
        if char == '"':
            # Check for escaped quote (two double quotes)
            if i + 1 < len(line) and line[i+1] == '"':
                current_field.append('"')
                i += 2
            elif in_quotes:
                # End of quoted field
                in_quotes = False
                i += 1
            else:
                # Start of quoted field
                in_quotes = True
                i += 1
        
        elif char == ',' and not in_quotes:
            # Field sepa

Here's a Python implementation of the `retry` function with the specified requirements:

```python
import time
import json
import traceback

def retry(fn, *, attempts: int = 3, base_delay: float = 0.5):
    """
    Retry a function with exponential backoff.
    
    :param fn: Function to be called
    :param attempts: Maximum number of attempts (default 3)
    :param base_delay: Initial delay between retries (default 0.5 seconds)
    :return: JSON with result details
    """
    last_exception = None
    
    for attempt in range(1, attempts + 1):
        try:
            result = fn()
            
            # Successful execution
            return json.dumps({
                "code": 0,
                "explanation": f"Success on attempt {attempt}"
            })
