Repository navigation
v1.2 - Rich content, large-history performance, and safer project matching
Highlights
- Load official Claude export ZIPs directly, or drag and drop ZIP/JSON files into the viewer
- Browse edited and regenerated conversation branches
- Search within a conversation, navigate highlighted matches, and copy individual messages as plain text
- Render artifacts, Mermaid diagrams, generated files, and web search results
Reliability and security
- Preserve orphaned messages with a clear fallback view
- Restore artifact theme rendering and harden SVG/iframe sandboxing
- Fix syntax highlighting in local
file://usage and safely handle raw Markdown HTML
Performance
- Progressively render long conversations and defer expensive rich content
- Cache rendered pages and initialize Mermaid only when needed
- Build project relationship indexes asynchronously in batches with race and failure recovery
Project association accuracy
Project inference is now precision-first. It uses unique file evidence, project knowledge searches, and project-unique keywords while rejecting ties and low-confidence matches. Ambiguous conversations remain unassigned instead of being forced into the wrong project.
