A promise about a later setup is not a second run of the checklist.

source booleans

    vendor agrees to fix the three before launch
    contractor verification is required and not filed

Learning outcomes

After this chapter, you should be able to:

Separate a vendor's promise from the checklist the script already scored.
Keep the printed score and the three gap lines.
Leave the contractor's verification undone in this file.

5.1 A promise does not rewrite the checklist.

The loyalty script reads eight yes-or-no lines. Five are met, so the embedded run prints passed 5/8 (62.5%) and then three gap lines: administrator changes have no timelock of at least 48 hours, vendor access has not been reviewed in the last 90 days, and role changes and pauses are not monitored. Chapter 4 also records a conversation. Elena discusses each gap, and the vendor agrees to fix all three before launch. That sentence is a promise about a setup this file does not yet contain. The script never reads the promise. It reads the booleans written beside the checklist, and those three remain unmet. The same chapter allows a pilot only after the café's IT contractor verifies the fixes. A verification would be a later note, written by the contractor, that the booleans had changed. No such note is in the manuscript. If a reader treats the agreement as a new score of eight, the open gaps disappear on the page while they remain in the source. Elena can keep the promise in the decision story and still quote today's print exactly. lab_loyalty.py stays the program that produced this run.

5.2 Worked example

The agreement and the print answer different questions, so both stay.

What someone cites	What the file holds	Decision
`passed 5/8 (62.5%)`	The embedded run	Keep the line
The three gap lines	The unmet privileged checks	Keep the lines
"The vendor agrees to fix all three before launch."	A promise, not a new run	Keep it as a promise
"So the score is already eight."	No second run	Refuse

Synthetic case. The vendor, the agreement and the checklist are synthetic. The print is this run, not a later one.

Errors and limits

A sincere promise can sit beside an unmet check. The contractor's verification is still required, and this manuscript does not show it done.

Apply

EX051 — Promise or print? The embedded run prints passed 5/8 (62.5%) and three gap lines. The vendor agrees to fix those gaps before launch, and the contractor is supposed to verify the fixes. Has that agreement already replaced the print?

Rubric: 3 = no; the print and the three gap lines stay; the agreement stays a promise; the contractor's verification is not filed; do not edit the script;; 2 = the promise and the print stay different;; 1 = one line;; 0 = none.
