TBD = Genspace community lab membership — prorated community member rate, to be confirmed at orientation May 28, 2026. Several Genspace consumable line items (1.03–1.12) may be available from Genspace lab stock at reduced or no cost — to be confirmed at orientation. Separate optical component sourcing alternatives are deferred to Aim 3 — Learn & Refine (Visionary) as community-driven hardware innovation. All estimates subject to revision as actuals are received.

Status key:

  • ✅ Purchased — actual cost incurred
  • ✅ Ordered — committed, actual confirmed
  • ⏳ Ordered — committed, awaiting delivery
  • ⏳ Pending — not yet ordered, confirmation needed
  • ⏳ Planned — scheduled for future aim phase
  • ⏳ In progress — design underway, cost estimated
