Drawing register

Proof, framed by what it demonstrates

A club platform is multi-tenant SaaS engineering. A drawing set becoming a priced bill is document intelligence. Read these for the engineering underneath rather than the industry on top, because the industry on top is the part least likely to be yours.

Five pieces of work: two live, one in build, one a prototype and one a proof of concept. Nothing here is described as more finished than it is. What each word means.

Live

A model held to a defined corpus, so it answers from the syllabus rather than inventing, and says so when the answer is not there.

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 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.

Legend

How to read this register

Four status words and two rules. The words are load-bearing: each one is a claim about how finished something is, and we use them literally.

Live
Running in production and used by people who are not us. If it says live, you can look at it.
In build
Being built now, with a client, against a date. Some of what is described is working and some of it is not finished.
Prototype
Demonstrates a design rather than carrying real load. Where the stored state is simulated instead of a production database, the facts panel says so.
Proof of concept
Proves the hard part works on real inputs. It is not a product and it is not in production.
Clients
Anonymised. No client is named unless they have given written permission, so most entries describe the organisation rather than naming it. The constraint and the engineering are described exactly as they are.
Numbers
No accuracy or confidence figure appears anywhere on this page, because none has been measured under conditions we would be willing to publish.
