Live- Goes in
- A student’s question, and one ingested, versioned syllabus corpus
- What we built
- Retrieval restricted to that corpus, so the answer comes from the chapter
- Comes out
- An answer out of the syllabus, on an installable web app
- The line it does not cross
- A question outside the corpus gets a refusal rather than an improvisation
Note 1 · The constraint
Students already use general chatbots for homework. Those tools do not know which syllabus a child is on, wander outside the chapter, and answer a Class 8 question at undergraduate level. On a shared family phone with a patchy connection they are worse than nothing.
Note 2 · What we built
A retrieval pipeline that restricts answers to an ingested syllabus corpus. When a question falls outside the ingested material, the answer is a refusal rather than an improvisation. That refusal is the feature. Grounding of this kind reduces invention substantially; it does not eliminate it, and the product is built on the assumption that a wrong answer is still possible.
Note 3 · What transfers
The control you need before a model is allowed to speak about your products, your policies or your prices. The mechanism that makes it refuse is the same one that keeps it inside your documentation.
