TraceCoder: Explainable and Auditable Code Generation with Position-Key Snippet Versioning

Short summary

TraceCoder introduces a snippet-history schema that records per-repair-event metadata (benchmark reference, failure text, LLM explanation) alongside a browser-based visualization tool and a stable position-key indexing scheme for code snippets. Evaluated on 30 algorithmic tasks, three in ten snippets carry a traceable repair-event row. The system makes the internal narrative of automated code generation auditable and replayable, which is essential for trust in production deployments.

• •Relational schema records provenance for every code repair event in LLM-based generation
• •Browser visualization renders repair history as heat-mapped, annotated source code
• •30% of snippets carry traceable repair events; enables full auditability of generated code
