Definitions
In plain terms

Technical
For V_t=0, Contribution_t=0; this is distinct from a zero price return.
Scope
Do not infer that a flat VPT row means the close was unchanged.
Examples
- A reviewer computes VPT Zero-Volume Contribution from a small OHLCV fixture and checks readiness, units, and edge cases before publication.
