v1.0.3

What's New in v1.0.3

Security

• Cache directory created with 0o700 permissions, mitigating pickle deserialization risks
• Path traversal checks on CSV and Parquet output paths (`.." rejection before resolve)
• Cache deserialization errors caught gracefully instead of propagating

Architecture

• CacheLayer and TickerOrchestrator support context manager protocol (with statement)
• CacheLayer.close() is idempotent; __del__ releases file descriptors
• _set_identity() serialized via lock to prevent races in concurrent usage

Financial Accuracy (v1.0.2)

• Net Debt/EBITDA uses financial debt only (excluding lease liabilities) for consistency with standard EBITDA
• Amended filings (10-K/A) preferred over base filings when filed more recently
• 8 metrics restored in model round-trip (Quick Ratio, Cash Ratio, Debt/Total Capital, Cash Flow Coverage, Fixed Charge Coverage, Accruals Ratio, Earnings Quality, Sloan Accrual)
• JSON serialization round-trip: NaN → null → NaN survives correctly
• New AnalysisResult.from_json_dict() for deserialization

Documentation

• README updated for all v0.8–v1.0.3 features (valuation ratios, financial company detection, Z'' model, context managers, JSON round-trip, alerts_config)
• setup.py version synced, development status upgraded to Production/Stable
• SECURITY.md supported versions updated to 1.0.x

Testing

• 400 tests passing on Python 3.10, 3.11, 3.12, 3.13
• +24 new tests across security, architecture, and financial accuracy
