Ward 4B's cabinet has flagged a controlled-drug discrepancy overnight. You are the pharmacist investigating. The transaction log will tell you who — but who is not the same as why.
Five sources of evidence are available. Each one you open is recorded. You will be asked to name a cause and choose an action, and a plausible wrong answer is available from the very first screen — a named nurse whose count does not balance.
Two indices are tracked separately from your mark: Investigation quality, which falls when you conclude without the evidence, and Fairness, which falls when you attribute a systems failure to a person.
Complete the investigation to generate your report, then write and submit it below.
