Intent stays separate
Was intentional deception established?
No
- Detailed assessment
- Not established
- Intent evidence level
- 0 / 3
The cited evidence establishes material missing context, framing, delay, or partial delivery, but it does not directly establish Musk’s contemporaneous knowledge or purpose. Misleading outcome and intentional deception are evaluated separately.
“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 mattersEvidence 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.
Quality and directness of evidence that Musk made the statement.
Quality of evidence establishing the outcome.
Independent corroboration across sources and domains.

- v4 → v5 source-package migration audit
- Audited, no headline change. Evidence and derived statistics re-audited.
- Selection basis
- Material v3 expansion claim selected under published inclusion rules
- Source quality
- Original statement or strong reporting paired with a major wire, official record, court filing, or established fact-checker V4 evidence metrics: statement 24/30; outcome 31/40; corroboration 0/15; directness 12/15.
- Methodology note
- V5 uses strict-promise-v1.0. Later delivery does not earn partial credit for a missed dated promise. Scored under the v3 Misleading category at 50 points. This rating measures demonstrated reliability and does not by itself establish deceptive intent.
