Assemble the kit, prove every spare, and label what has not been proven

short · 45 min · Objective 5.2

Task

Build the physical kit, test every spare before it earns the label known-good, and record explicitly which items are unproven -- because an unproven spare contaminates every test it takes part in.

Steps

  1. Write lab/kit/contents.csv with header item,have,proven,proved_how,date covering measurement tools, hand tools, consumables, spares and protection.
  2. For every spare, test it in a working machine and fill proven and proved_how with what you actually did, not with yes.
  3. Label the proven spares physically and record the labelling in lab/kit/labelled.txt.
  4. Write lab/kit/unproven.md listing every item you could not prove and what proving it would require -- an item on this list is not a spare, it is a part.
  5. Write lab/kit/software.csv with header tool,purpose,writes_to_disk for the bootable drive's contents, marking which tools modify a disk and therefore must not run before a copy.

Verify

awk -F, 'NR>1 && NF>=5 {n++} END {print n" kit item(s)"}' lab/kit/contents.csv
awk -F, 'NR>1 && tolower($3)=="yes" && $4!="" && tolower($4)!="yes" {n++} END {print n+0" item(s) proven with a method"}' lab/kit/contents.csv
grep -c . lab/kit/labelled.txt
grep -c . lab/kit/unproven.md
awk -F, 'NR>1 && tolower($3)=="yes" {n++} END {print n+0" software tool(s) that write to disk"}' lab/kit/software.csv

Eight or more items inventoried, at least two proven with a stated method, a labelling record, an unproven list, and at least one software tool marked as writing to disk. A software table where nothing writes to disk has not included a partition or imaging tool.

Notes

lab/kit/unproven.md is the file that keeps the kit honest. The moment an unproven part is used as a known-good substitute, every conclusion drawn from that test is unsupported.
