Intent stays separate

Was intentional deception established?

No

Detailed assessment
Not established
Intent evidence level
No conclusive state-of-mind evidence

The evidence establishes the outcome or factual error but does not conclusively establish knowledge of falsity at the time of the statement.

“No” does not mean the statement was true. It means the cited evidence did not meet the higher standard needed to establish the speaker's state of mind.

Why this distinction matters

Evidence strength

A disclosed measure of evidence quality—not a probability.

Component scores measure source quality, corroboration, and directness. Verdict confidence begins with that evidence strength and applies the deductions documented in the methodology.

V5 expansion selected under published materiality and evidence rules

Methodology note
V5 uses strict-promise-v1.0. Later delivery does not earn partial credit for a missed dated promise. False does not automatically establish intentional deception.
