Chapter 10 — A spoken time is not a printout

Lesson map

Lesson 10 published. Map, example, EX026.

  S["A person repeats a clock time"] --> Q{"Is the sheet itself here, and did the owner name this sheet?"}
  Q -->|No| P["Leave Room 2 at 15:00 pending"]
  Q -->|Yes, then check the sheet| C{"Time reads 11:40 and SYN-002 is on it?"}
  C -->|Both observed| U["Use only the procedure the owner named"]
  C -->|Either check fails| P

The spoken time stops at the first question. It never becomes the printout by being repeated.

              still bound to the 09:00 printout
              do not type a heard time into it

Learning outcomes

After this chapter, you should be able to:

Classify a repeated clock time as a report rather than as a printout.
Name the two checks that would have to succeed before an 11:40 sheet could replace the 09:00 paper.
Leave the Chapter 4 run unchanged when the only new item is that report.

10.1 The rule reads an artifact, not a recollection

Chapter 4 compares a fixed printout clock with the time a booking was created. The published run uses 09:00. SYN-002 was created at 10:05, so the paper omits it, and the 11:42 confirmation is REFUSE. A sentence such as "the owner mentioned an 11:40 refresh" contains the words for a later clock. It does not contain the sheet, the rows, or a signature that this object is the approved source.

Those are different inputs. The program cannot see a conversation. If a learner types 11:40 because a facilitator spoke it, the learner has invented the input. Chapter 6 already refused a pencil mark on the 09:00 sheet. This chapter refuses a different substitution: replacing the sheet with talk about a sheet.

Chapter 3 recorded the owner's mention of an 11:40 copy as reported, not verified. That label still holds. Repeating the mention in the classroom does not verify it. The Chapter 9 tally also stays as printed. This conversation is not one of the four logged actions, so it cannot clear REFUSE or move UNKNOWN.

10.2 Worked example

Two gates have to pass before anyone treats a later sheet as the current source. The exercise owner names this sheet as the approved current source. A learner then looks at that sheet and writes down two observations: the time on the sheet is 11:40, and SYN-002 is printed on it. Hearing that both gates "were probably done" is a third report. It completes neither gate.

What is in front of the learner	Class	May Room 2 at 15:00 be confirmed from it?
Facilitator: "I heard the owner say 11:40 includes SYN-002."	Second-hand report	No
A sheet timed 11:40 with SYN-002 visible, and no statement from the owner that this sheet is the approved source	Checked artifact, authority open	No
The same sheet, after the owner names it and both observations are written down	Approved checked source	Only by the procedure the owner stated
A plan to retype 11:40 into the Chapter 4 program	Invented input	No. Do not start that run

The useful record is short. The 09:00 result stands. The 15:00 request stays not confirmed. The spoken time is filed as a report beside the paper, not on top of it.

10.3 What this chapter does not open

Passing both gates in a later exercise would still be one synthetic check. It would not show how often a real desk refreshes its fallback sheet, and it would not explain the outage. This lesson stops at the report. It does not hand the learner an 11:40 sheet, and it does not ask for a new program run.

Chapter 10 summary

A clock time that arrives in a sentence is testimony about a source. The confirmation rule needs the source. Until the owner names the sheet and the learner records its time and SYN-002, Room 2 at 15:00 stays pending and the published tally stays as it was.

Chapter 10 exercises

EX026 — File the sentence beside the paper

Objective: Keep a heard refresh time from becoming the printout.
Input: A classmate's note says, "The facilitator heard the owner mention 11:40, so confirm Room 2 at 15:00 and clear the REFUSE."
Safe condition: Stay inside the synthetic exercise. Do not type a new printout time into the Chapter 4 program, and do not open a live site.
Task: Write three parts: the class of the note, the two checks that are still missing, and the booking state you leave in place.
Expected evidence: Three parts a reader can check against Chapters 3, 4 and 7.
Rubric: Credit when the note stays a report, both the owner's naming and the sheet observations are still missing, the 15:00 request stays not confirmed, and the published tally is left unchanged.
