Data honesty
Every number shown to a user must be traceable to a verified source.
Rules
- A price is shown only when it was retrieved within the freshness window
- Stock status is shown only when the retailer reports it
- Illustrative data in mockups and documentation is always labelled as such
- A missing value renders as absent, never as zero or as an estimate
Why
The product competes on trust, not on coverage. One wrong price costs more than ten missing ones.
