 # TACTBench Demonstration Samples
 
-This repository contains five short demonstration excerpts from TACTBench. It
-does not contain the TACT training set or the remaining hidden TACTBench
-evaluation set.
-The samples illustrate the public data schema and five pedagogical response
-patterns used by TACT: direct correction, error explanation, guided revision,
-clarification checking, and an encouraged retry.
+This repository contains five short full-context demonstration examples from
+TACTBench. It does not contain the TACT training set or the remaining hidden
+TACTBench evaluation set. The samples use the same full-history representation
+as the benchmark evaluation and illustrate prompting, affective feedback,
+retry elicitation, error flagging, hinting, and guided revision.
 
 ## Data
 
-- `data/demo.jsonl`: five excerpts from five distinct tutoring conversations.
-- Each row contains the two most recent dialogue turns, the reference teacher
-  response, and its tutor-strategy label or labels.
-- Each excerpt contains fewer than 100 words of source dialogue and reference
-  text.
-- The original full dialogue context is intentionally omitted.
+- `data/demo.jsonl`: five complete benchmark contexts selected from four
+  tutoring conversations.
+- Each row contains the full visible dialogue history before the target teacher
+  turn, the reference teacher response, and its tutor-strategy label or labels.
+- Each complete example contains fewer than 100 words across its full dialogue
+  history and reference response.
 
 These rows are demonstration examples and must not be included in future hidden
 benchmark scoring. Historical paper results were computed on the original
