01 / The theatre of an answer

Not every question
gets an answer.

Sometimes, withholding one is the ending.

Eight sources can arrive. An answer still has to earn its place on the stage. Scroll to follow two recorded queries to two different endings.

02 / Before the answer

A stage.
A finite world.

This is a bounded collection of drug guidance.

MedRAG retrieves from that collection. This theatre is an editorial world; it is not a clinical interface, and it gives no medical advice.

03 / Recorded query 1

Eight pieces
arrive.

Retrieval brings material into reach.

The evaluation records eight retrieved chunks. Their positions here are composed for the story, not similarity scores or embedding coordinates.

04 / What travels with it

Three citations
remain attached.

The answer does not travel alone.

Query 1 was not refused. Three chunks were cited. The evaluation preserves these counts, but not the answer wording or identities of the chunks.

05 / Try the contrast

Same retrieval.
Different ending.

Switch between the two recorded queries.

Watch the stage change between an answer with citations and a refusal. These are two existing evaluation records, not new model calls.

Query 1: 8 retrieved, 3 cited. Not refused.

06 / Recorded query 7

Again,
eight.

An empty answer does not mean an empty retrieval.

The second query also retrieved eight chunks. Finding material did not guarantee that an answer followed.

07 / The empty stage

The most important
part is missing.

Zero cited. Refusal recorded.

The scenery moves to the wings. We keep the absence visible. The metadata records the refusal; it does not tell us its causal reason.

08 / The result in full

Restraint belongs
in the result.

Four refusals in twenty recorded queries.

This is the final recorded RAGAS evaluation from 3 February 2026, using vector-only retrieval. It is an evaluation record, not evidence of clinical safety.
