Name the trap before you punch keys.
Fourteen families have a worked four-option check under owner-authorized AI review. Fire egress keeps the earlier overlay: 8,000/15 is 533.33 and rounds up to 534. That overlay is not a new item-bar approval, not human SME approval, and not a pass-rate claim.

Incident / performance rates
Trap: Use 100,000 worker-hours, or treat first-aid-only cases as DART.
Correct method: OSHA TRIR = (recordable cases × 200,000) / hours worked. DART uses days-away/restricted/transfer cases only.
Worked: 4 recordables, 800,000 hours → (4 × 200,000) / 800,000 = 1.0.
Guided: Hours 400,000. Recordables 3. DART cases 1. Compute TRIR then DART. Hint: 200,000 hours, not 100,000.
Independent: A site works 1,250,000 hours with 5 OSHA-recordable cases, 2 of them days-away. Report TRIR and DART.
Timed (90 s): In 90 s: 6 recordables, 900,000 hours. TRIR?
Unfamiliar transfer: A Gulf contractor uses 1,000,000 man-hours and 4 first-aid-only cases plus 1 restricted-duty case. Which rate, if any, is a US OSHA DART analog — and what must you chip?
Professional interpretation: A falling TRIR with a rising DART means severity, not count, is the story. Do not celebrate a rate without the case definition.
Remediation: /indicators then delayed retest at ~24 h. Open live solver →
