  K --> M{"Is the replacement a memory or the lab file?"}

A report of loss is not a new census of names.

Logical drawing

habit: lost papers go to Kwame the same day
the counter sheet is gone
    |
    +-- memory is not the sheet
    +-- the twelve-row laboratory file is not the café's paper
    +-- no lost name is invented to fill the mail

Learning outcomes

After this chapter, you should be able to:

  1. Report a missing sign-up sheet to Kwame on the day it is noticed.
  2. Refuse a send list typed from what people think they remember.
  3. Keep the laboratory's five addresses out of the café's working list.

14.1 The missing paper and the teaching file are different objects

The habit already says a lost paper or device is reported to Kwame the same day. The sheet that sat by the counter is gone. A colleague wants the afternoon newsletter to leave anyway, typed from names people believe they saw, and wants the five laboratory addresses pasted in because those were "the valid ones." The laboratory file is a twelve-row exercise. Its print describes that file. It is not a copy of the paper that left the counter. Kwame writes that the sheet is missing and dates the note. He does not assemble a send list from recollection, and he does not treat the synthetic rows as the customers who signed.

Proposal What stands in for the missing paper Decision
Tell Kwame today and date the notebook The habit's report Accept
Type the names staff think they saw Memory Refuse
Paste the five laboratory addresses into the café list A teaching file Refuse
Email "whoever we can still name" this afternoon An invented list Refuse

Synthetic case. The names on the lost sheet are not in the case file. Do not supply them.

Errors and limits

Reporting the loss does not show that someone copied the sheet, and it does not authorise a fresh collection by itself. A later stack of forms is judged on its own dates, which Chapter 19 takes up. This chapter does not name a finder or a thief.
