- citationParser.ts: extractCitedSources() parses answer text for [citations],
resolves against SourceMetadata, returns deduplicated cited sources
- ResponsePanel.tsx: useEffect fires POST /api/v1/v2/highlights/batch after
answer renders; View PDF link upgrades in-place to highlighted HTML when
batch completes; stays as raw PDF on failure
- Updated plan: LLM-based relevance detection, eager background computation,
single batched LLM call, sqlite cache, regex sentence splitter
- 45 frontend tests: 28 citationParser + 17 ResponsePanel (including 4 new
sub-question highlight tests)
ResponsePanel now calls processCitations() on answer text before rendering.
Custom ReactMarkdown 'a' component adds target="_blank" to all citation links.
Adds tests for citation link rendering and unmatched citation fallback.
