02 · Ways in
Start where it catches.
Choosing, starting, continuing, returning, changing the conditions, noticing, discovering, or not knowing what you need yet.
These name doors, not chapter order. You are never asked what you are, only what is catching today.
Way inRecogniseOne moveEvidenceToolsOpen
Nothing has to be named. This way in assumes you cannot yet say what you need, and it does not ask you to.
- RecogniseA page that needs no word from you.
- One moveWe make the page ask less, rather than asking more of you.
- EvidenceStaying on one page counts. That is the record.
- ToolsA corner clip, so the page can be found again.
For when something is off and it has no shape yet. We widen the view a little, without asking you for a conclusion.
- RecogniseNotice what is here before deciding what it means.
- One moveChange what you are looking at, not how hard you look.
- EvidenceOne pass, whether or not it resolved.
- ToolsPages you can point at instead of describe.
For when there are several possible next things, and the choosing itself has become the thing that catches.
- RecognisePut the options where you can see them at once.
- One moveWe cut the field down until a choice is physically possible.
- EvidenceThe one you took, not the best one.
- ToolsA cut tool that holds one option in place.
For arriving. Starting is kept apart from continuing, because beginning and carrying on are different jobs and need different pages.
- RecogniseFind the first physical thing to touch, not the first task.
- One moveWe move the start closer to where your hands already are.
- EvidenceThe smallest visible part, done.
- ToolsA construction face that stands up on a surface.
For when something is already going, and the question is how to keep contact without starting the whole thing again.
- RecogniseFind the nearest live point in the work.
- One moveWe change the conditions so the thread survives a gap.
- EvidenceOne unit added. No catching up.
- ToolsA marker that keeps the live point findable.
For when the move is fine and the room is not. We change what is around you rather than what is in you.
- RecogniseName one condition that is doing the blocking.
- One moveAlter light, sound, surface, distance, or who is there.
- EvidenceOne physical change. The task can wait.
- ToolsPlacing tools for the room itself.
For coming back after a gap of any length, with no backlog to clear and no explanation owed.
- RecogniseSee what is still standing, not what lapsed.
- One moveWe re-enter at the nearest point, not at the beginning.
- EvidenceResumed, at any size.
- ToolsA page that marks where you came back.
For keeping evidence. This is where one changed fact gets recorded, and where anything unhelpful gets thrown away.
- RecogniseRegister one thing that actually changed.
- One moveKeep only what helps you next time.
- EvidenceOne line, one mark, or nothing at all.
- ToolsA clip whose notches read helped, unsure, or hard day.
Marks show what each way in carries. In the book you find the pages with the printed edge index, not by reading from the front.
JobTrace the loop without a starting line
DoTrace · enter anywhere

03 · The loop
Change one part. Make one move. Keep one fact.
Three beats, in the same order, on every way in. It is a loop, not a ladder. Beginning in the middle still counts, and rest does not erase what you kept.
Something catches.
One part can change.
One move becomes available.
One fact is different.
Capacity changes
quietbusyclearfoggyheldalone
The book adapts the move. It does not grade the weather.
Cognitive offloading, implementation intentions, attention research and choice architecture inform specific design decisions. They do not prove that this product has clinical effects. No adult SEND study has been run yet. One is a release gate, and so is physical testing.

Two hundred and thirty pages in six working parts. Open the stack and take each one out.
Six working parts.
Open the stack, then take out any part to see what it does. Nothing here needs to be understood in order.
- Cover and spine. A printed landscape with a four-colour track down the spine.
- The Landing, pages 3 to 10. One physical act, a ledger you need not fill in, three doors, the waymarks, the cost of travel, and one tool buried in the outer corner.
- Eight ways in, 176 pages. Needs-led routes, each with its own pages and its own way out.
- Wonder Leave, 22 pages. Ten engineered spread openings that ask nothing of you.
- Fourteen tools, 32 pages. Construction faces with mirrored reverses, so a page still works after it is cut.
- Edge index. Printed colour on the outer edge, so you find a page by looking at the closed book.

JobFind one usable signal
DoPoint · cover · place · leave closed
ThenNothing you point at is stored
Collectible 01 · Visual sidekick
Everything can be real. Not everything has to become a task.
Open this when the field is too loud. Find one signal that can change the next minute. Point, cover, place, or leave it closed.
No streak. No diagnosis. No debt. Use it alone or slide it beneath the Dot Dock band on the main field book.
Point to one signal
You belong before the signal is clear.
Choose one signal, not a complete explanation. Nothing you point at is stored.
- Body
- Something in the body is asking first. Change one physical condition before anything else. Water, warmth, posture, light. Stop when that is enough.
- Place
- The room is doing some of the work. Change the place rather than the person. Move one object, one door, or yourself two metres.
- Task
- The task has no visible first edge. Find the first physical place where the action would actually begin. Touch that, not the whole task.
- People
- Somebody else is in the loop. Ask for one clear thing. Change the support, not the standard. One message, one ask, or one deliberate absence.
- Not sure
- Not sure is a complete answer. Nothing needs naming. Stay for as long as it is useful, then leave without finishing anything.

This went on sale before every test was finished. That is a choice, and this is the whole of it. We will not replace missing evidence with launch language, so here is the log instead.

230 interior pages and 24 Signal Lens pages pass structural, margin, font and mechanism checks. Passed on v4.9.

Physical proof In the post
Print colour, binding, trim, edge index and every construction page tested in the printed object. A copy is ordered. It has not arrived. When it does, the renders here become photographs of it, good or bad.

Destruction test Not yet
Tear, fold, place, close, shake and repeat. No reverse-side content can be lost. Nothing here starts until the copy is in a hand.

Adult SEND formative study Not yet
Real readers decide whether the pages feel like company or weight, and whether each first move is understood. No study has been run. Nothing is claimed on the strength of one.
