Limitations
- Order revenue positive,product cost/fixed fulfilment fee nonnegative,percentage selling fee0–100%,conversion probability0–100%. Contribution may be negative;then no nonnegative ad budget breaks even,reported explicitly. Revenue uses one entered average order,excludes refunds,taxes,repeats and attribution inference. No ad-account mutation or recommended spend.
- Scalar controls accept explicit finite decimal syntax;positive values normally1e-12–1e12,nonnegative0–1e12 unless a narrower range is stated. JSON numeric rows use finite IEEE754 values within their stated bounds. Derived counts above1billion and nonfinite results refuse. Combined input<=400000UTF8 bytes;complete JSON<=4MiB.
