# Market Signal

## Purpose

This document defines how `whynot` records and interprets early signals from potential users, collaborators, customers, or investors.

## Signal Principles

- Signals are evidence, not vibes.
- Weak signals are useful if clearly labeled.
- Contradictory signals should be preserved.
- A signal should be connected to a prototype, audience, or hypothesis.
- Lack of signal is also information.

## Signal Strength

| Level | Name | Meaning |
|---|---|---|
| S0 | No Signal | No observable interest or usefulness |
| S1 | Weak Signal | Some curiosity, comments, or informal interest |
| S2 | Medium Signal | Repeated interest, specific feedback, or trial use |
| S3 | Strong Signal | Users take action, return, refer, contribute, or ask for pricing |
| S4 | Commercial Signal | Users pay, pre-order, commit budget, or request procurement path |

## Signal Review Questions

- Who produced the signal?
- What did they actually do?
- What did they merely say?
- Was there cost, effort, risk, or commitment involved?
- Does the signal point toward a specific product, offer, or community need?
- Does the signal justify another experiment?
