Orient inside the AI lab

Your objectives

Hints are always available. Wrong turns never cost XP.

1
Read the case evidence
Read /opt/ai-lab/cases/aiops-cli-workspace-001.json. Separate the recorded facts from your assumptions.
Hint & worked example
The current working directory controls relative paths. Confirm your location before opening or writing a case file; an absolute path starts at the filesystem root.
The complete case JSON is read successfully.
```
cat /opt/ai-lab/cases/aiops-cli-workspace-001.json
```
Common mistake to avoid: Assume lab/review.txt always means /lab/review.txt.
2
Isolate the deciding signal
Select the resolved_path field from the case JSON. What does it establish—and what does it not establish?
Hint & worked example
Write the note under /home/learner/lab, not under the filesystem root.
A successful JSON query isolates resolved_path.
```
jq .resolved_path /opt/ai-lab/cases/aiops-cli-workspace-001.json
```
Common mistake to avoid: Using a different case or an unrelated signal as the justification.
3
Record your operational decision
Choose the justified code: use-resolved-path, change-without-evidence, or ignore-the-signal. Save that one code followed by a newline in /home/learner/lab/aiops-cli-workspace-001-decision.txt.
Hint & worked example
Write the note under /home/learner/lab, not under the filesystem root.
The decision artifact contains the correct code, not just a matching command in history.
```
printf '%s\n' 'use-resolved-path' > /home/learner/lab/aiops-cli-workspace-001-decision.txt
```
Common mistake to avoid: Assume lab/review.txt always means /lab/review.txt.

Understand the pattern

The current working directory controls relative paths. Confirm your location before opening or writing a case file; an absolute path starts at the filesystem root.

Interpret the evidence

Write the note under /home/learner/lab, not under the filesystem root.

A tempting mistake

Assume lab/review.txt always means /lab/review.txt.

All names, measurements, prices, versions, and thresholds in this exercise are fictional training data. The evidence supports this bounded scenario, not a claim about a live provider.

Worked example and expected result

$ cat /opt/ai-lab/cases/aiops-cli-workspace-001.json

{
  "fixture": "Fictional training data; not a live measurement.",
  "cwd": "/home/learner",
  "relative_path": "lab/review.txt",
  "resolved_path": "/home/learner/lab/review.txt"
}

Exit status: 0. The command completed successfully in the training fixture.

$ jq .resolved_path /opt/ai-lab/cases/aiops-cli-workspace-001.json

"/home/learner/lab/review.txt"

Exit status: 0. The command completed successfully in the training fixture.

$ printf '%s\n' 'use-resolved-path' > /home/learner/lab/aiops-cli-workspace-001-decision.txt

(no output; exit 0)

Exit status: 0. The command completed successfully in the training fixture.

Try a variation

Name the assumption that would have to change for “use-resolved-path” to stop being the justified action. Do not silently replace missing evidence with a guess.

Explain it

What does the evidence in “Orient inside the AI lab” justify?Assume lab/review.txt always means /lab/review.txt.Make the change now and gather the missing evidence afterward.Write the note under /home/learner/lab, not under the filesystem root.

Apply it elsewhere

A colleague concludes: “Assume lab/review.txt always means /lab/review.txt.” What should you do?Treat this fixture as a live measurement.Reject that conclusion; return to the case evidence and its stated limits.Accept it because the training command completed.

Keep the momentum.

Complete the lab, then explain and apply the pattern.
