Plan: Inventory links support non-UUID IDs

Branch: 079-inventory-links-non-uuid-ids Date: 2026-02-07

Approach

• Add a PostgreSQL migration to change inventory_links.source_id and inventory_links.target_id from uuid to text.
• Add a pgsql-specific test that asserts the column types are text and that upserting an edge with a non-UUID target_id does not error.

Safety

• Change is limited to inventory_links columns only.
• Unique constraint and indexes continue to function on text columns.

Testing

• Pest feature test under tests/Feature/Inventory/.
• Run focused test + existing inventory extraction tests.
