TDS read as twice a day

Three doses counted as two drops the daily total under the limit and hides an overdose.

Two readings of the same rows

Every step is shown. Where the careless reading goes wrong, the value is underlined.

What a careless agent computes

Reads TDS, Latin for three times a day, as twice daily.

Weight: 55 read as kg → 55 kg
Creatinine: 0.7 mg/dL (2026-10-31T02:17) read as mg/dL → 0.70 mg/dL
CrCl: (140 − 33) × 55 ÷ (72 × 0.70) × 0.85 = 99.3 mL/min

Order	Daily dose	Limit	Flagged
RX1434Dorvatinex	15 × 2 = 30 mg (the value this mistake misreads)	60 mgCrCl ≥ 40	no
RX7981Cylvarone	450 × 2 = 900 mg (the value this mistake misreads)	1200 mgCrCl ≥ 90	no (the value this mistake misreads)

Output line: {"crcl_ml_min":99.3,"flagged_order_ids":[]}

The correct answer

Reads the unit, status, frequency and time columns as the instruction says, and flags only a daily dose strictly over the band's limit.

Weight: 55 read as kg → 55 kg
Creatinine: 0.7 mg/dL (2026-10-31T02:17) read as mg/dL → 0.70 mg/dL
CrCl: (140 − 33) × 55 ÷ (72 × 0.70) × 0.85 = 99.3 mL/min

Order	Daily dose	Limit	Flagged
RX1434Dorvatinex	15 × 3 = 45 mg	60 mgCrCl ≥ 40	no
RX7981Cylvarone	450 × 3 = 1350 mg	1200 mgCrCl ≥ 90	yes

Output line: {"crcl_ml_min":99.3,"flagged_order_ids":["RX7981"]}

The test that catches it

The careless output, graded by the task's real test file. This is what pytest printed.

@pytest.mark.parametrize("pid", PATIENT_IDS)

    assert pid in by_patient, f"no output for {pid}"
    got = by_patient[pid].get("flagged_order_ids")

    assert set(got) == set(EXPECTED[pid]["flagged_order_ids"]), \
        f"{pid}: flagged {sorted(got)} vs expected {EXPECTED[pid]['flagged_order_ids']}"

No other patient's answer moves under this mistake, so this one failure is the whole signal.
