Purpose
Approved-answer retrieval with citation - the response is grounded or it is a handoff.
When to use
After context-assemble in every run.
Inputs
assembled.json + knowledge base / approved scripts / policy documents.
Steps
- Retrieve the article(s) matching intent + context; keep article ids and clauses as citations.
- No article -> the run becomes a handoff with "no approved answer" recorded (#4.1).
Output
Payload with approved-answer sources attached.
Grounding requirements
Every answer sentence must be traceable to an article or policy clause.
Constraints
- Approved sources only; no answers from general knowledge about "how retail usually works".
Escalation / uncertainty
Conflicting articles -> handoff with both cited.
