What would overturn it

A named Saudi or coalition strike operation against Houthi positions, versus continued reliance on air-defense interception and diplomatic protest alone.

The verdict

Non liquet  Resolved 5 Oct 26.

The coalition vowed retaliation, and announced 'Yemen Dawn' air support on Oct 5, one day after the window; no confirmed named Saudi strike specifically in retaliation by Oct 4 was found.

Retaliation timing: Saudi chose a broader offensive launched just after the deadline.

As logged at issue

Saudi Arabia is unlikely to announce a named kinetic strike on Houthi launch sites within two weeks of the Riyadh airport hit, continuing to rely on air defense and diplomatic pressure -- unless the Aramco Yanbu claim is confirmed, which would sharply raise the odds of a direct response.
