Turn 1 · editing a formerly shared answer

The journey the space experience could not finish: Kitchen and Pantry are linked and share Tile Selection, the owner takes the two spaces apart, and the answer that was shared has to become an ordinary Kitchen answer that can be changed for Kitchen alone. The phone frames run in order, the desk frames follow, and the two collaborator views close it out. The shared answer is a destination rather than a row that does nothing, the unlink sheet keeps the existing selection pattern, and every action names the spaces it reaches. Nothing here changes the linking or reconciliation flow.

1k Where the journey starts

The space's own actions sheet, unchanged from the linking flow except for one row: managing the linked spaces is where unlinking lives, and the row names them rather than saying "unlink". Naming the set sits beside it and opens 1s. Only the account owner sees these rows at all. Managing opens 1c.

1a Kitchen, while the spaces are linked

The link is a sentence in the meta line and two space cards, not a badge. The shared answers are chevron rows that go somewhere — 1b — and the note under them is the only place the screen says what an edit reaches. The kebab opens 1k, which is the way to 1c.

One answer, held by both spaces. Opening either row while they are linked changes it in the kitchen and the pantry together.
1b The shared answer, while linked

A screen and not a sheet, because the reader can afford to lose their place and the answer is a record they arrive at. It says one answer is held by two spaces rather than pretending each one recorded it, and the primary carries the scope in its own label. Two ways out sit under it: answer this one decision separately and stay linked (1r), or take the spaces apart altogether (1c).

While the two spaces are linked there is one tile answer between them, so a change here lands in both. To change it in the kitchen alone, unlink the two spaces first. Change it for Kitchen and Pantry
1r What these spaces answer together

Linked spaces answer jointly by default, and this is the one place that default can be read and changed a decision at a time. A decision turned off is still in both spaces; it is just asked in each of them. This is the lighter half of the pair: 1c ends the link, this changes one answer's scope and leaves it standing. Try the rows.

Choose the island
{{ sharedLine }}
Whatever is recorded now stays in both spaces, with the date it was given and where it came from. From then on the kitchen and the pantry are asked separately for that one decision, and everything else carries on being asked once.
1t Linked, and disagreeing about one thing

What 1r returns to, and the state the space screen could not previously say: still linked, still sharing paint, and answering tile on its own. The shared run holds one answer and the space's own run holds the other, with the same provenance line 1d uses. Opening tile from here lands on 1e, scoped to Kitchen.

Tile is asked in each space from today. The pantry keeps matte porcelain until somebody changes it there.
1c Unlinking the two spaces

The existing linked-spaces sheet, unchanged in pattern: the space you are in as a plain row with its marker, every other space pickable, the retained count in a line under them, an outline action in primary ink. Nothing red and no confirmation after it, because nothing recorded is lost. Try the rows — the count and the action follow, and with one space left the label says what it does.

{{ keptLine }}
Both answers stay recorded in the kitchen and in the pantry, with the date they were given and where they came from. From then on each space is asked on its own, and an answer in one space does not move to the other.
1s Naming the linked spaces

From the space actions in 1k. A set goes by its spaces' names joined until the owner names it. The name is what the house board prints on the set's card (Space Groups 3a) and what this sheet and the space's meta line call it. It changes no answer. Clearing the field returns to the joined names, and the action says so. Try typing.

The house board draws these two spaces as one card, and this is the name on it. Nothing they answer changes.

1d Kitchen, after unlinking

The linked-with line, the space cards and the shared run are all gone. Tile and paint are now ordinary Kitchen answers in the space's own run, each with a chevron, and each carrying one restrained line saying where it came from. "Shared with the pantry until today" is there because without it the reader has two answers in a space they do not remember giving.

Choose the island
These three are the kitchen's own answers now. Changing one of them changes it here and nowhere else.
1e Changing it for Kitchen alone

The same destination as 1b, with the scope line and the action's label both saying Kitchen. The pantry is named before the save rather than after it, so the reader knows what does not move. The history is the answer's own timeline, which is where "it was shared, and then it was not" belongs — a space screen should not have to carry it. Pick a different tile; the action follows.

{{ saveLabel }}
{{ pantryLine }}
1f Back in Kitchen, with the two spaces apart

Where 1e returns to. The row carries the new value and today's date, and one line states the other half of the truth: the pantry still holds what it held. No banner, no "saved" — the record on the row is the report.

Choose the island
The pantry still has matte porcelain, 12×24, recorded 2 March. The two spaces answer tile separately from today.
1m The pantry, the same afternoon

The other half of the claim 1f makes, and the frame that makes the divergence testable rather than asserted. The pantry kept matte porcelain and its own provenance line, and nothing about the kitchen's change reached it. One note names the difference, because a reader who remembers one tile answer needs to be told there are now two.

Choose the shelving
The kitchen recorded honed limestone for its own floor today. This space keeps matte porcelain, and the two are separate answers from now on.
1p The same space, signed in as Sarah

Everyone on the build reads the link and the answers it holds; only the account owner sets them. So the run behind reads as it does in 1a, with what is waiting named as Philip's and no action on it, and the actions sheet is 1k with the managing row absent rather than present and unpressable. Nothing here says she lacks a permission — the row is simply not one of hers.

You are hereKitchen3 waiting on Philip
1q The shared answer, as Sarah reads it

The same destination as 1b, with the record intact and the two controls gone. The person is named rather than the permission, and the one thing she can do from here is a real button. The scope sentence stays, because what the answer covers is a fact about the answer and not about who is reading it.

Philip is the only person who can change this answer. While the kitchen and the pantry are linked it is one answer between them, so a change would land in both.
1g Desktop · Kitchen while the spaces are linked

Two columns from a shared header row: the space and what it is waiting on at the left, the linked spaces and the answers they hold at the right. The shared run stays a run of rows rather than becoming a panel, because the width is the only thing that changed.

One answer, held by both spaces. Opening either row while they are linked changes it in the kitchen and the pantry together.
1h Desktop · the shared answer, while linked

The desk has no back chevron in its chrome, so the route back to the space is the up-link above the head. The record is on the left and everything that acts on it is on the right, with the scope stated above the action rather than inside it.

{{ backToKitchen }}

1i Desktop · unlinking the two spaces

Still a sheet, because the space behind it is what the reader is deciding about and they come straight back to it. Side-anchored past the tablet rung, same rows, same count line, same outline action. The rows are live here too.

{{ keptLine }}
Both answers stay recorded in the kitchen and in the pantry, with the date they were given and where they came from. From then on each space is asked on its own, and an answer in one space does not move to the other.
1j Desktop · changing it for Kitchen alone

The width lets the history sit beside the choice instead of under it, which is the one real difference from the phone. The scope line is directly above the action, and the action names the space it saves to.

{{ backToKitchen }}
{{ saveLabel }} {{ pantryLine }}
1n Desktop · Kitchen after the change

Where 1j returns to, and the desk twin of 1d and 1f at once: no linked-spaces column, the answers run standing on its own, the new value and today's date on the row, and one line saying what the pantry still holds.

Choose the island
The pantry still has matte porcelain, 12×24, recorded 2 March. The two spaces answer tile separately from today.
