// Retire-planner PS pension tests — run: node tests/ps-pension.test.js (PS-PENSION-PLAN.md Stage 3)
|
||||
// Hand-computed cases A–J from the plan (AMPE proxy = 2026 YMPE = 74,600), verified to the cent,
|
||||
// plus engine integration checks (bridge window, start-age gating, PIA gating, pre-65 splitting).
|
||||
//
|
||||
// NOTE (documented in PS-PENSION-REPORT.md): two plan cases contain arithmetic typos.
|
||||
// The module implements the PSSA formula exactly; expected values here are the
|
||||
// formula-correct results of the plan's OWN inputs:
|
||||
// H: plan says lifetime 67,680.75 → correct is 67,681.25 (= 0.01375×74,600×35 + 0.02×45,400×35
|
||||
// = 35,901.25 + 31,780.00).
|
||||
// I: plan says lifetime 41,422.50 / total 54,011.25 / from65 35,209.125 → correct is
|
||||
// 41,411.25 / 54,000.00 / 35,199.56. Proof: the plan's own identity
|
||||
// lifetime+bridge (avg≤AMPE case) = 2%×100,000×27 = 54,000, and 41,411.25+12,588.75 = 54,000.
