Spanfold comparison debug

Segmented live pipeline backlog

Inspect which windows were active, where sources overlapped or diverged, and whether live rows are final or provisional.

Window Timeline

Each lane shows normalized windows after selector, scope, known-at, and open-window policy have been applied.

Segment Context Bands

Bands show the segment values attached to aligned windows, making phase, period, and other boundary changes visible before inspecting individual rows.

Aligned Segments

Segments are the comparison-ready temporal pieces. Their colour shows whether target and comparison windows were both active, target-only, comparison-only, or empty.

Diagnostics

Diagnostics explain validation and execution concerns that affect whether the result can be trusted.

No diagnostics were emitted.

Metadata

Compact extension metadata explains derived artifacts such as cohort activity evidence.

No extension metadata was emitted.

Rows And Finality

Comparator row counts show which analytical questions emitted evidence. Finality rows explain which live results may change after open windows close.
