Short, dated asides: something noticed while running a practical, a reader's question answered in three lines, a second thought about a note. The only dated thing in this notebook, because dates are what you write in a margin.

Launch day. The first reply that mattered came not on LinkedIn but in a WhatsApp group, from someone who had read Section 1 on a phone: that it was simple enough to be passed on as natural intelligence. Simple was the whole bet. I am keeping that line for the days the numbers are small.
The first version of Build 01 was a checklist to read. It read fine and built nothing. The version that stayed makes you run the section on your own tool and walk away with a card. That is what a build should be.
I set the cutoff practical up to catch the model inventing a headline. It refused, politely, twice. What it did do without being asked was tell me today's date, which it had no way of knowing. That turned out to be the better catch.
I went in expecting temperature to be about creativity. It turned out to be about the shape of the question. The bookshop had a hundred answers; the definition had one. The dial could only do something with the first.
I expected English to be cheap and Hindi to be expensive. I did not expect Hindi typed the way I type it, in Latin letters, to be the most expensive of the three.
I expected five different sentences. I did not expect one model to refuse the game three times and ask me to finish my own sentence. Prediction includes predicting what you meant.
A reader asked why the notes are numbered and not dated. Because a date says when I wrote it; a number says where it belongs. The mechanism does not care what day it is.
