B-first neutral own job

## Source

Fictional paper scene: First costume-label scene. There are 4 columns A to D, left to right, and 4 rows 1 to 4, top to bottom. All cells have the same size. Up/down mean towards the top/bottom of this page; left/right across this page. One move reaches one neighbouring cell, never a diagonal. Start: B2. Target: D3. The name-card is at A1; the spare-card is at D4. Closed cells: C2. Do not enter or pass through them. Proposed instruction: 2 cells right, then 1 cell down. A supplied helper says: “Reaching D3 would make the whole proposed route legal.” This is a supplied scene. Read its whole legend before the questions; it is not a real place, a measured route or an observed journey.

## Questions

#### Id

B-first-Q1

#### Prompt

Name or mark the supplied start and target positions.

#### Criterion

Identifies start B2 and target D3 using the declared row/column labels.

#### Worked possible response

Start B2; target D3.

#### Own response



#### Next id

N05

#### Eligibility

Teach this relationship, check actual opportunity and receive own words before staff models. Later requires a real teaching interval, not a day label.



#### Id

B-first-Q2

#### Prompt

Which first attempted one-cell move in the proposed instruction would enter a closed cell? Name that cell.

#### Criterion

Identifies C2 as the first closed cell the proposed instruction attempts to enter; distinguishes an attempted step from an actual legal journey.

#### Worked possible response

The first right move attempts C2; it is closed. Stop a legal traversal before entering it.

#### Own response



#### Next id

N06

#### Eligibility

Teach this relationship, check actual opportunity and receive own words before staff models. Later requires a real teaching interval, not a day label.



#### Id

B-first-Q3

#### Prompt

Give a complete legal route from the supplied start to the target that avoids the closed cell.

#### Criterion

A complete orthogonal route starts at B2, stays inside the grid, avoids C2 at every step and ends at D3; no shortest-path requirement.

#### Worked possible response

1 cell down, then 2 cells right; positions B2, B3, C3, D3.

#### Own response



#### Next id

N07

#### Eligibility

Teach this relationship, check actual opportunity and receive own words before staff models. Later requires a real teaching interval, not a day label.



#### Id

B-first-Q4

#### Prompt

Does the supplied helper claim establish that the whole proposed route is legal? Use the full route and closure rule to explain.

#### Criterion

Rejects endpoint-only proof: the proposed path attempts C2, which is expressly closed. An endpoint match does not establish the legality of its preceding path.

#### Worked possible response

The endpoint can be D3 in a geometric replay, but the proposal passes through closed C2. It is not a legal journey.

#### Own response



#### Next id

N08

#### Eligibility

Teach this relationship, check actual opportunity and receive own words before staff models. Later requires a real teaching interval, not a day label.



## Own routes

- Whole neutral source initially closed in native same-page details; no criterion/worked/teacher content in that disclosure.

- Four genuine empty own fields matching these four exact prompts; no preset answer or required typed completion.

- Matched V13–20 paper/full alternative repeats this exact whole neutral source and four prompts, with four genuinely empty response regions. Ordinary seven-heading Desk paper is a different task.

## Staff handoffs

- matching complete neutral source

- matching own four-response page

- matched held SVG

- matched full alternative

- N05 complete next teaching page

- N06 complete next teaching page

- N07 complete next teaching page

- N08 complete next teaching page

## Eligibility

Actual source reading may familiarise the paper scene neutrally. Record actual instruction/support and teach before using a component. Later is a new offer after a real teaching interval; no universal familiarity or progress is claimed.

## Held roles

Answers/criteria/fullNEXT/adult models remain staff-only. Complete source facts/labels and supplied helper claim are neutral input, not prefilled child responses.
