# Sample Venture Research Sources

Everything linked here is fictional training data for **The Sample Venture**.
It does not describe real people, businesses, customers, or market research and
must never be cited as real evidence.

Use the canonical
[fictional public-signal log](./evidence/source-log.md) for the problem
validation tutorial. It contains five stable source labels (`SV-SRC-001` through
`SV-SRC-005`), source and access dates, a simulated signal, and a limitation for
each record.

Keep these boundaries visible:

- The references use `.invalid` domains and cannot be real websites.
- The records are a safe practice route, not proof of market demand.
- Do not mix these records into a real venture source log.
- Use the separate labeled fictional interview notes only when a later tutorial
  asks for customer-conversation evidence.
