\toprule
Item & Protocol \\
\midrule
Coding unit & One policy x exposure-dimension pair; the unit is the positive reward amount conditional on eligibility. \\
Direct amount term & Code only when an additional unit of the named exposure changes the disclosed positive amount, rate, threshold, or cap. \\
Eligibility safeguard & Code an approval, disqualification, incident, or complaint threshold separately when it affects entry but not the disclosed conditional amount. \\
Exposure proxy condition & Use only for a clause that explicitly links an observable proxy to eligibility or amount; do not infer a proxy from location, aircraft class, or approval alone. \\
Not disclosed & Use when no direct amount term or explicit proxy condition is visible in the extracted official reward text; this is not evidence about wider regulation. \\
Audit trail & Store the author semantic classification and rationale separately from the deterministic exact-term search; flag any disagreement for manual reinspection of the archived full text. \\
