Post-June/July2026 navigator staffing and current contract continuation not independently verified. Do not turn the assessment subcontract into treatment or a contract expiry into proof of closure/unfunded need.","boundary":"One unrestricted $100,000 foundation gift. Only hypothetical HCV navigation-to-additional-cure component quantified; all remaining gift cost retained, other health benefits/harms unquantified. End Hep C project donation route is not substituted for general giving.","assumptions":"Every numerical scenario input is an analyst judgment. Cure difference is a prospective navigation-versus-actual-available-care probability among confirmed-viremic people offered support, includes completion/failure, and is not measured SFPHF efficacy. Offered navigation cash includes allocated screening failures, all navigation and partner administration/overhead. No second adherence or overhead multiplier.","health":"Reference QALYs are already discounted lifetime MONARCH-style gains per added cure. A finite 20-year allocation heuristic with weights k^shape/(1+d)^k is normalized to that total; not a rerun of disease progression. Reinfection and EXCESS mortality beyond reference mortality truncate benefit; later cure truncates the relevant fraction. Zero irreversible pre-catchup disease credit after cure; no transmission bonus. Gift-to-cure delay discounted once.","cost":"Core donor package = navigation cash + donor DAA share * extra starts per offer * DAA resource cost/start. Main donor share zero is hypothetical public/insurance payment, not verified new capacity. Gross envelope adds unpriced noncash inputs plus remaining medication cost on nominal offers/starts before funding replacement. Counts medication once; no net-social-cost claim and no subtraction of future medical savings.","funding":"Existing public support, funded clinical partners, other donors and restricted balances form baseline. Financial additionality represents replacement of funded navigation; incremental cure probability separately compares clinical access against actual care. Current discretionary allocation, waitlist and incremental funding gap unmeasured.","geography":"All modeled health US. Bay includes SF; shares are beneficiary-residence priors, not service-location proof. Nested ledgers never summed. Harms use same partition here.","overlap":"Foundation, EndHepCSF, SFAF, GLIDE, SFCHC, Springboard and other providers cannot each claim full same-patient cure/tail. Transfers are not added resources. No new naloxone or opioid-treatment survival stream credited.","formulas":{"offers":"G*allocation/(navigationCash+donorDAAShare*startDifference*DAACost)","additionalCures":"offers*cureDifference*fundingAdditionality","health":"additionalCures*referenceQ*retainedNormalizedWeights/(1+discount)^giftToCure
