[CC-003] AWS Cost Explorer pagination may be incomplete

[LFigg]

Description

AWS Cost Explorer API supports pagination via NextPageToken but the code may not properly handle pagination for very large result sets.

Location

• File: cost_collect.py - AWS cost collection function

Impact

• Medium - Cost data may be truncated for accounts with many services/resources
• Incorrect cost totals for large AWS organizations

Suggested Fix

Ensure proper pagination loop:

results = []
next_token = None
while True:
    params = {
        'TimePeriod': {...},
        'Granularity': 'MONTHLY',
        'Metrics': ['UnblendedCost'],
        'GroupBy': [...]
    }
    if next_token:
        params['NextPageToken'] = next_token
    
    response = ce_client.get_cost_and_usage(**params)
    results.extend(response['ResultsByTime'])
    next_token = response.get('NextPageToken')
    if not next_token:
        break

Priority

Medium
