Thanks for the detailed write-up — confirmed on current master.
In ts/src/okx.tsparsePosition, the cross branch uses imr + upl as collateral, but the isolated branch uses only margin (collateralString = this.safeString (position, 'margin')). So for isolated positions collateral ignores unrealized PnL, and marginRatio = mmr / collateral stays around mmr / margin instead of rising toward liquidation. The unified position structure defines collateral as affected by PnL, so the isolated branch should be margin + upl, matching cross. With your numbers that gives 2.697 / 60.634 ≈ 0.0445.
OKX's native mgnRatio is a different metric (equity / (mmr + fee), higher is safer), with the inverse direction of ccxt's marginRatio, so it stays available as position['info']['mgnRatio'] and isn't mapped into the unified field.
I'll open a minimal fix for the isolated branch shortly.
