What Hype is tracking

Removes a major certification bottleneck: H55's completion of the regulator‑witnessed lithium‑ion propulsion battery module test campaign establishes an evidentiary precedent authorities can reference for module‑level approvals, reducing a key gating factor for electric flight.
