## Chapter 17 — A habit is a schedule, not a second run ### Lesson map Lesson 17. Map, example, EX063. ```mermaid flowchart TD H["Five habits on a printed list"] --> S["No later script"] R["Change record has a date field"] --> B["No date is printed"] S --> K["The embedded prints stay"] B --> K ``` The list tells Ellen when to look again. It does not contain the next look. ### Logical drawing ```text monthly device list, after closing three months firmware check guest passphrase every few months, and after staff leave accounts password manager and a second step for email and the order platform other people's kit call the provider dates printed none ``` ### Learning outcomes After this chapter, you should be able to: 1. Repeat the five habits without adding a sixth as if it were on the list. 2. Keep the change-record fields distinct from printed values. 3. Leave both embedded prints as they are. ### 17.1 The pinned list allocates future attention. It does not store future evidence. Chapter 4 leaves Ellen five habits: check the router's device list monthly; check for firmware updates every three months; change the guest passphrase every few months and after staff leave; use a password manager and a second step for email and the order platform; and call the internet provider or the payment company for problems with their equipment. Each habit has a reason already taught. The monthly list is how the dictionary stays related to the leases. The firmware interval is shorter than the 540-day age that failed the check. The guest passphrase is the shared secret of a network visitors use. The password manager and the second step protect the three items chapter 3 marked, at the account layer rather than the LAN layer. The phone call is the third-party rule. A sixth habit can be a good idea later. It is not on this list unless Ellen adds it in a new note this book does not contain. The change record is easy to confuse with a completed calendar. Its fields include date, time, what changed, the original value, the new value, and who approved it. "Date" here is the name of a column. No calendar date is printed. The original administrator secret is not printed. The new one is not printed. The after-checklist is saved "with the date," and that date is also unprinted. A report that fills those blanks is more specific than the evidence and therefore worse. Neither habit has been performed inside this file as a second run. There is no later lease table and no later settings dictionary. The report Ellen keeps, on paper with the router documents and as a digital copy in her cloud storage, quotes the work. Storing a report does not re-execute a script. Nadia reviews the report before Ellen receives it. Review is an editorial step. It is not a new measurement of firmware age. ### 17.2 Worked example | Item | In the file | Decision | |---|---|---| | Five habits, including the provider phone call | Chapter 4 | May stay | | Date as a column name | The record's fields | May stay | | A printed calendar date | Absent | Do not add | | A second lease run attached to the monthly habit | Absent | Do not add | > **Synthetic case.** The pinned list is a piece of paper. It is not a log archive. ### Errors and limits A column called date can be empty. An empty column is not a date you may choose. ### Apply - **EX063 — Which later run do you attach?** The report lists five habits and Ellen keeps it. The change record has a date field. What date do you print, and which second script output do you attach? *Rubric:* 3 = no date is printed; no second lease run or settings run is in the file; the five habits stay the five; the stored report does not change either print;; 2 = no second run and no invented date;; 1 = the habit list only;; 0 = none. ### Continue studying — lesson 17 (chapter 17 of 20) [← Chapter 16](#ch-16) · [Course chapter index](../SUBJECTS.md) · [Chapter 18 →](#ch-18) Continue to the next authored lesson. ## Worked answers **EX063.** No date is printed, and no second run is in the file. The five habits stay the five. The stored report does not change either print.
