What is being worked on now, what has been found, where things contradict each other, and the rules both sides of this are following. Nothing here is finished.
Holding iOi's core activities once, so events can be assembled from them.
What an activity record is, the axes the thirteen really differ along, and how the same activity is rewritten for a teacher.
Open →Seven axes across eleven events, the document hierarchy, and what the corpus cannot tell us.
Open →Five marks, two canvases, no colour in the markup. Read off your own example boards.
Open →East London Mosque, Saturday 29 August 2026. Seven stations, nine activities.
Stations, activities, timings and the open questions.
Open →Five makes, twenty step panels. The fly half of Nature in Motion.
Open →Two chassis, three drives, one of which does not yet run. The roll half.
Open →Straw air rocket and balloon rocket. The only activity that throws something.
Open →Adapting an activity for a teacher is three jobs, not one. The materials list and the challenge line are a filter a script can do. The technique text is the same facts at a different length. The hook, curriculum links, key stage, questions and outcomes exist nowhere upstream and are written fresh every time. Only the third is expensive.
The corpus holds no post-delivery record of any event. The Marner teacher responses predate the Day of Play and ask only prospective questions. Meath Gardens' notes file is still empty two weeks after delivery. So no structure in the corpus is evidence of correctness, including the recent ones.
Marner's unit is the classroom, 23 of them. Meath Gardens has neither stations nor classrooms. The station layer is real but describes one event, not the general shape.
The wind tunnel has a fan and two glue guns. Across its 28 material rows there is no socket, no extension lead and no plug. Every other powered activity says how it is powered.
A launch lane needs clear floor at an event expecting 400 visitors, and nothing on file describes the room. The safety controls are written but marked as proposed for that reason.
Three activities are make, then test. They are exactly the three that were repeatedly mistaken for one another. It was treated as a naming problem; it was a category the record had no way to express.
Nature's Engineers is richer in the internal record than on the live website. Paxton, the Crystal Palace, the water lily and the James Webb telescope are in one and not the other.
The drawing marks were only ever tested on paper. Dowel, straw, bottle cap, elastic band and balloon all worked, because a mark describes what a line means to the maker rather than what the thing is made of. One gap: nothing could say a rod runs through a tube.
None of these are resolved. They are listed so they can be, and several are only visible because two independent readings disagreed.
| Two column schemes | Eleven materials files use seven columns, two use nine. The validator meant to prevent this does not exist yet. |
| Event facts on activity records | day_note is event scoped by decision and sits on 56 activity rows, so one record carries facts true of one venue on one day. |
| Quantities | Exist on one activity of thirteen. No pick list can be calculated for the other twelve. |
| Two volunteer rules | Marner says never unescorted, which needs an escort rota. ELM says never alone with children, which needs station cover. Both read from the same answer, and they cost different things. |
| No ratio anywhere | Across eleven events, no document states an adult to child ratio. Two state a headcount, on two different bases. |
| One idea, three words | Three activities on one station independently reached for flight, forces and movement. Deliberately left uncoined. |
| Opposite directions | no power and mains power describe the same property from opposite ends, so an activity carrying neither cannot be told from one nobody assessed. |
| Theme or tag | Four words live as both. Nothing has ever settled what the two lists are for. |
| Near duplicates | glue gun against glue guns. nature and biomimicry always appearing together. |
| Two revision orders | The taxonomies log newest at the bottom because I said so; the event plan logs newest first. My instruction, not a pre-existing split. |
| A pattern outlawed the same day | Nature's Engineers opens with four figures of which two are empty. That was the house pattern in the morning and is not any more. |
| Rival notes | Three agents wrote three overlapping method notes because none could safely edit another's file while running. |
Two sets. The left is yours and settles what the work is. The right is mine and settles how it gets made without falling apart when several of me run at once.
