Lineage Sankey

The central visual evidence for the kosha-collapse finding: six PWG <ls> labels (left) flow through the actual kosha works they name (middle), then converge into MW's single <ls>L.</ls> hedge (right).

Trust Block

• Evidence: hard-coded PWG and MW citation-flow counts from the documented kosha-collapse analysis.
• Limitations: this is a focused explanatory visual, not a complete source graph or a generated review queue.
• Validation: checked by npm run build; counts should be regenerated before paper-final use.
• Owner repo: csl-atlas.
• Next use: treat the chart as structural evidence, then check companion docs before making a lineage claim.

What the diagram shows

Stage 1 (left, six green nodes): PWG's six most-cited named kosha labels with their actual citation counts.

Stage 2 (middle, six pink nodes): the kosha works behind those labels. Hemacandra has two — Abhidhānacintāmaṇi (the main lexicon) and the Anekārthasaṃgraha (his polysemy supplement).

Stage 3 (right, one blue node): MW's single <ls>L.</ls> hedge — collapses all six PWG flows into one. 40,212 citations, 13.95% of all MW entries.

The collapse is the story. PWG distinguished six named koshas. MW (and PWK before it) dropped the named-source apparatus and replaced it with L. — gaining typographic compactness, losing bibliographic precision.
