UI patterns
- Footnotes [1][2] mapped to chunk metadata
- Quote-only mode—answer must be substring of provided context
- Highlight passages in side panel
Prompt instruction
instruction = """Use ONLY PROVIDED_CONTEXT. After each claim add [n] matching chunk id.
If context is insufficient, reply: INSUFFICIENT_CONTEXT.""""Verification
Post-check that cited chunk IDs exist and support the sentence—automate with entailment models or human spot checks.
