Canonical status
confidence: mediumSource status (Polymarket)
Derived status (Orrery)
Reason
Liquidity is below $1,000 — price discovery is unreliable.
The derived status is computed from the source flags plus the live YES price, so a market trading near a rail can read as PRICE-PINNED while upstream is still active. That isn't the same as resolved.
