CrisisBrief was sharper on this question — by lower Brier against the same outcome.

The market-implied probability on the day we sealed our call, pinned once and never re-snapshotted. We forecast independently — the market is the benchmark, not an input.

HOW IT RESOLVED

Resolved by independent prediction-market settlement: the matched Polymarket market "US announces end of Iranian blockade by August 31, 2026?" settled NO. CrisisBrief's sealed forecast is graded against that same outcome. The link to that market is ledger entry 9485, sealed late: the link was made before links were sealed.

Adversarial verification: confirmed (independent verdict: false).
