The exhibits
Companion documents
This memorandum is the second gate in a two-document chain. Cases are screened and ranked against capacity in the pipeline; only what clears the gate earns full diligence here. A decline returns the case to the rack with corrected figures.
DWG IE-001 · The screening gate
The Innovation Engine
Sixteen requests, one capacity gate. Cheap estimates, ranked honestly. SPC-1042 clears it at a $1.45M screening value.

This document
The committed case, diligenced: the screening estimate is haircut to defensible streams and printed as an $885K NPV the committee can sign.
The method
Discounted cash flow over the stated horizon · IRR by bisection · MIRR at the discount rate · realization haircut on benefits · one-at-a-time sensitivity · Monte Carlo risk.
