2 supported 1 partly supported 0 contradicted 5 not checkable as stated how the 8 claims stand · each chip opens the sources

8 assertions · 1 insight · every statement was checked. The predictions and assertions are the 8 claims: statements the public record can support or contradict. 3 are resolved, and 5 name no date, number or outcome precise enough to check. Everything else (opinions, insights, what ifs, disclosures) can never be settled by the record, so it carries no assessment.

The record, in short

What the tape says about how Haoyuan argues and how the claims held up. Everything they said, and everything said about them, is in the tabs below.

Their most notable supported claim

Alluxio open-source project reaches nearly 250 contributors across 50 organizations

Expressed certainty vs assessment result

none yet certainty 1
none yet certainty 2
none yet certainty 3
50% certainty 4
100% certainty 5

weighted support: a fully supported claim counts one, a partly supported claim counts half. Each filled bar is clickable and opens exactly those claims; "none yet" means nothing said at that certainty level has resolved yet

How they sound: speaking style how? →

227 words/min while actually speaking · 39.2 um and uh per 1k words

No argument clarity score for Haoyuan Li: only 1 usable question→answer exchange on raw tape (a fair score needs 8+). We do not score a sample that small. Roundtable and news formats yield far fewer direct exchanges than interviews.

Measured by listening to the audio itself: 3,568 words across 1 episode of raw-level tape, transcribed verbatim with every um and uh kept, each one attributed only where the alignment onto our timed stream is unambiguous. These are measurements of speaking style. We do not rank them: across this corpus, fluency and argument quality are nearly uncorrelated (ρ≈0.2), and smooth talking does not signal clear thinking.
