Definition. A portfolio with charged preparation [ftip-00OH]
✍️source

    For difficulty \(n\), fix \(R\geq 1\) specified tasks, their common evaluation convention and a portfolio success condition: each task's recipient attains expected fresh-task score at least \(\tau \). An admitted assisted construction pays preparation \(S(n)\) once and at most \(c(n)\) per task, including failed consultations and acquisition. Its actual joint schedule therefore has additive work at most

    \[U_R(n)=S(n)+R c(n),\qquad \frac {U_R(n)}{R}=\frac {S(n)}{R}+c(n).\]

    This charges the whole preparation cost to the portfolio. A single campaign does not gain extra cash from anticipated future users. Count maintenance over the service interval and capacity needed for all tasks in \(S\) or \(c\); peak resources and time come from the actual schedule, not this sum.

    Let \(L_R(n)>0\) be a lower bound on the total hard additive work of every admitted autonomous portfolio meeting the same success condition, including permitted shared training and development. One cannot obtain \(L_R\) by adding isolated-task lower bounds without proving that sharing does not invalidate the result. Marginal comparisons may disclose sunk preparation on both sides; lifecycle comparisons must charge both.
