Checkpoint Anomaly Scoring

This analysis uses only the frozen wormhole ladder metric summary. Features were standardized before anomaly scoring.

Feature Set

• OPL mean
• OPL max
• portal-hit density
• throat-event density
• crossings per pixel
• segments per crossing
• average segments per ray

Ranked Results

Checkpoint	z-score distance	isolation forest	local outlier factor	mean rank
post_throat_backstep_01	4.3999	0.6160	1.3496	1.00
exit_lookback	2.9376	0.5157	0.9677	3.00
mouth	2.0098	0.4512	1.0020	3.67
post_throat_exit_approach	2.5274	0.4898	0.9622	4.00
throat	1.1279	0.4208	1.0489	4.33
mouth_to_throat_approach	1.5206	0.3949	1.0020	4.67

Interpretation

• Dominant transport anomaly verdict: yes.
• The top-ranked checkpoint by combined anomaly ranking is post_throat_backstep_01.
• The bridge checkpoint post_throat_backstep_01 has scores z=4.3999, iforest=0.6160, and lof=1.3496.
• In paper-ready terms, the bridge is the strongest multi-metric outlier when anomaly is defined by simultaneous sparsity, transport inefficiency, and depressed optical path mean relative to the rest of the ladder.
