Why Category-First Product Research Is Clearer

Direct answer: Compare similar products using the evidence that matters for that category.
Research workflow
- Record the exact product or category clue.
- Separate visible evidence from assumptions.
- Search the local product index.
- Open and re-check the current SheetsIndex record.
Missing or inaccessible evidence should remain marked unknown. Do not infer authenticity, inventory, material, seller identity or quality from an image alone.
