I appreciate the detailed prompt, but I need to flag a critical issue: the brand-appliance pairing doesn't exist in reality.

"Boiler Sony" is not a real product line. Sony is an electronics manufacturer (consumer electronics, gaming, imaging); they do not make boilers. Boiler manufacturers are typically separate companies (Baxi, Worcester, Vaillant, etc.), and they don't use the Sony brand.

This creates an impossible situation:

1. I cannot write confidently about "how this appliance typically works" because there is no "Boiler Sony" category to draw general knowledge from.
2. Any invented details would violate the accuracy rules (no invented specs, no brand-specific claims that can't be universally true).
3. The result would either be generic boiler advice falsely attributed to a non-existent Sony product, or obviously fictional content.

What I can do instead:

• Write a guide for a real brand + appliance pair (e.g., "Worcester Boiler," "Baxi Boiler," or any actual Sony product category)
• Write a generic boiler owner's guide without falsely tying it to Sony
• Clarify if this was a test prompt and you'd like me to demonstrate the framework with a real pairing

Which would be most useful?
