## Chapter 16 — The permission dates stay off the page

<!-- open-cyber-academy:lesson-figures:start ch-16 -->
### Lesson map

Lesson 16. Map, example, EX062.

```mermaid
flowchart TD
  A["Rosa signs a permission note"] --> B["Payments stay hers"]
  B --> C["Stop cases go to Rosa, not into an investigation"]
  C --> D{"Are the calendar dates printed?"}
  D -->|No| E["Keep the signature and omit the days"]
```

A signed boundary still binds when the days are missing.

### Logical drawing

```text
on the note, in prose
    accounts Mia may look at
    second steps she may help turn on
    payments Rosa does herself
    Rosa's signature
not printed
    the calendar dates she agreed
stop rule
    break-in, odd payment, threat
    Mia tells Rosa and stops
    Rosa calls the provider or the bank
```

### Learning outcomes

After this chapter, you should be able to:

1. Say what the permission note allows and what it reserves.
2. Keep the stop cases with Rosa.
3. Leave the shop-calendar dates unprinted.

### 16.1 Permission is a signed limit. The calendar entry is not copied here.

Before any change, Mia writes a short note: which accounts she may look at, which changes she may make, such as turning on second steps, and which changes Rosa must do herself, such as anything involving payments. Rosa signs it. Mia keeps the signed note with her course notes. The signature lets Mia show she acted as asked. It does not let her cross into payments or into an investigation. If she suspects a break-in, sees a payment that looks wrong, or meets a message that threatens the shop, she stops, tells Rosa, and does not investigate alone. Rosa contacts the provider or the bank. Chapter 1 says Rosa agrees the week's dates and adds them to the shop calendar. Those dates are not printed. "Dates" as something a plan can have does not invent a day, a month, or a year for this shop. Finishing the checklist does not widen the note, and it does not move a stop case onto Mia's list of jobs. Working without the signature, even with good intentions, can cause confusion and harm. The file shows the signature. It does not show the calendar.

### 16.2 Worked example

Copy the boundary. Leave the unpublished days unpublished.

| Element | Shown? | Decision |
|---|---|---|
| Rosa's signature | Yes | Keep it |
| Payments reserved to Rosa | Yes | Keep the reserve |
| Stop, then Rosa calls the provider or bank | Yes | Keep the stop |
| A calendar date | Not printed | Do not invent one |

> **Synthetic case.** The permission note is not reproduced as a filled form. The shop calendar stays off the page.

### Errors and limits

An undated signature can still limit the work. Missing days do not make a payment change into Mia's task.

### Apply

- **EX062 — What do you add to the note?** Rosa has signed. A payment looks wrong, and the checklist is finished. Which date do you write, and who contacts the bank? *Rubric:* 3 = no date is printed; Rosa stays the person who contacts the provider or the bank; payments stay hers; Mia stops and does not investigate; finishing the checklist does not widen the note;; 2 = no date and Rosa keeps the escalation;; 1 = the signature only;; 0 = none.

## Worked answers

**EX062.** No date is printed. Rosa stays the person who contacts the provider or the bank. Payments stay hers. Mia stops and does not investigate. Finishing the checklist does not widen the note.
