🚩 Problem: Lack of schema visibility and safe access methods for extracting historical customer and project data from a Sage 50 Handwerk MS SQL backend.
📦 Existing: Sage 50 Handwerk installation, MS SQL Server backend (~50 GB, 10 years historical data).

Specifications:

[Target] Sage 50 Handwerk (Plus/Professional/Quantum)

Workflow:

1. Establishment of read-only SQL access or sandbox environment.
2. Schema mapping of core customer and project tables.
3. Analysis of free-text storage for trade-specific keyword extraction.
4. Identification of version-specific quirks and locking behaviors.
5. Architectural review of SQL-to-Postgres synchronization pipeline.
