Evidence before reassurance.

DishSignal is testing whether restaurant ingredient changes can be made easier to trace and communicate. The current prototype uses invented records and has not been validated as a food-safety system.

• No real restaurant data.
• No live supplier connection.
• No POS integration.
• No ordering integration.
• No food-safety validation.
• No regulatory approval.
• No measured time saving.
• No evidence of incident reduction.
• No autonomous decision-making.
• No guarantee that records are complete.

What must be tested

1. 01How supplier information arrives.
2. 02Who is authorised to update a recipe.
3. 03How substitutions work during service.
4. 04How cross-contact information is maintained.
5. 05How incomplete information should block publication.
6. 06What staff need during a busy shift.
7. 07What diners find understandable.
8. 08Whether an audit trail is operationally useful.
9. 09Whether this saves time or creates another system.
