I see you've shared requirements for ensuring stability and data accuracy in the Administrative Module and Reports Module. Let me explore the codebase to understand the current implementation and identify what needs attention.

I've reviewed the requirements document and have a good understanding of your codebase. The document outlines two main areas that need testing and verification:

1. Administrative Module (Stability & Security)

• User Management (CRUD operations with immediate permission changes)
• Chart of Accounts (SNCA) - Firebase sync for account creation/editing
• Global Settings (immediate recalculation when rates change, e.g., INSS)

2. Reports Module (Precision, Coherence & Performance)

• Balance Sheet & Statement coherence (Debits = Credits principle)
• Query performance (< 1 second load times)
• Export functionality (PDF/XLSX with proper formatting)

Let me explore the specific modules to understand their current implementation:

Let me search for the financial module and accounting-related components since the requirements mention balance sheets and statements with double-entry accounting principles:

I found the key financial components. Let me examine the chart of accounts, trial balance, and account statement components which are critical for the requirements:

Now let me check the journal entry service to understand how the accounting logic works:

I've now thoroughly reviewed your codebase. Based on the requirements document you shared, here's my analysis of the current implementation status:

Current Implementation Status

1. Administrative Module (Stability & Security)

2. Reports Module (Precision, Coherence & Performance)

Key Findings

1. User Management currently uses localStorage instead of Firebase - user changes are not persisted to the backend database.
2. Trial Balance and Account Statement have proper accounting logic with double-entry validation, but lack PDF export (only CSV).
3. The coherence principle is enforced - journal entries must balance before being saved.

Would you like me to:

1. Migrate User Management to Firebase for persistent, real-time user data?
2. Add PDF export to Trial Balance and Account Statement with professional formatting?
3. Add XLSX export functionality to all financial reports?
4. Add performance monitoring to ensure reports load in < 1 second?

Please let me know which improvements you'd like to prioritize, and I'll implement them systematically.
