How this entry was checked
- Commitment recordedThe company's words were matched word for word against the filing.
- First checkAn AI model, Gemini (Google), read the company's later filings and recorded the outcome with a quoted passage.
- Second check: agreesA different AI model, Claude (Anthropic), re-read the evidence without being told the outcome and reached the same answer.
- Third check on a negative finding: disagreesBecause a negative finding could harm a company if wrong, a stronger model re-read the evidence fully blind and read it as “Late”, so a person decides.
