Event: Next in-person Trump–Putin meeting.

Outcome: Resolves to the duration bracket of the longest single filmed handshake that day.

Measure: Time from first hand contact to final break of contact (regrips/second hand while maintaining contact = continuous).

Precision: Real-time timing to 0.1s. On a bracket boundary, pick the higher bracket.

Qualify: In person, voluntary, hand-to-hand (gloves OK), continuous video clearly shows start and end.

Exclude: Fist bumps/high-fives/hugs/hand-kisses/elbow bumps; unclear start/end; photos only; edited or sped-up clips.

No handshake or no meeting by Aug 31, 2025, 11:59 PM PT: resolves to the lowest bracket.

Sources: Use video; prefer official/uncut or major news raw feeds; if conflicting, use the clearest continuous viewand the longest defensible timing.
