Inspect index status

An index status must be read with document counts and readiness. A process being up does not guarantee that the index contains the expected records.

Your objectives

Hints are always available. Wrong turns never cost XP.

1
Read the case evidence
Read /opt/ai-lab/cases/aiops-retrieval-embeddings-005.json. Separate the recorded facts from your assumptions.
Hint & worked example
An index status must be read with document counts and readiness. A process being up does not guarantee that the index contains the expected records.
The complete case JSON is read successfully.
```
cat /opt/ai-lab/cases/aiops-retrieval-embeddings-005.json
```
Common mistake to avoid: Process liveness proves every chunk is indexed.
2
Isolate the deciding signal
Select the indexed_chunks field from the case JSON. What does it establish—and what does it not establish?
Hint & worked example
Investigate the missing chunks before marking the index ready.
A successful JSON query isolates indexed_chunks.
```
jq .indexed_chunks /opt/ai-lab/cases/aiops-retrieval-embeddings-005.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: wait-for-index-completion, change-without-evidence, or ignore-the-signal. Save that one code followed by a newline in /home/learner/lab/aiops-retrieval-embeddings-005-decision.txt.
Hint & worked example
Investigate the missing chunks before marking the index ready.
The decision artifact contains the correct code, not just a matching command in history.
```
printf '%s\n' 'wait-for-index-completion' > /home/learner/lab/aiops-retrieval-embeddings-005-decision.txt
```
Common mistake to avoid: Process liveness proves every chunk is indexed.

Understand the pattern

An index status must be read with document counts and readiness. A process being up does not guarantee that the index contains the expected records.

Interpret the evidence

Investigate the missing chunks before marking the index ready.

A tempting mistake

Process liveness proves every chunk is indexed.

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-retrieval-embeddings-005.json

{
  "fixture": "Fictional training data; not a live measurement.",
  "process_alive": true,
  "expected_chunks": 842,
  "indexed_chunks": 512,
  "ready": false
}

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

$ jq .indexed_chunks /opt/ai-lab/cases/aiops-retrieval-embeddings-005.json

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

$ printf '%s\n' 'wait-for-index-completion' > /home/learner/lab/aiops-retrieval-embeddings-005-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 “wait-for-index-completion” to stop being the justified action. Do not silently replace missing evidence with a guess.

Explain it

What does the evidence in “Inspect index status” justify?Make the change now and gather the missing evidence afterward.Investigate the missing chunks before marking the index ready.Process liveness proves every chunk is indexed.

Apply it elsewhere

A colleague concludes: “Process liveness proves every chunk is indexed.” What should you do?Reject that conclusion; return to the case evidence and its stated limits.Accept it because the training command completed.Treat this fixture as a live measurement.

Keep the momentum.

Complete the lab, then explain and apply the pattern.
