A structural embedding browser over 300 software engineering tasks. Each point is one instance; proximity = procedural similarity — positions are computed by UMAP over pairwise AST edit-operation distances, not semantic embeddings.
Fix types are derived in two stages: (1) hunk-local AST features are extracted from the diff (node types, control-flow signals, API calls); (2) an LLM classifies the patch into a closed vocabulary using those features as grounding. Labels are structurally anchored, not free-form.
Color by fix type, repo, pass/fail, coverage, quadrant, or models solved. Filter by fix type, repo, or model outcome. Click any point to inspect per-model outcomes, behavioral metrics, and fix summary.
