An in-development logbook for skydivers and BASE jumpers that compares a person’s record with the requirements for a licence, rating, or prospective jump.

Why it surfaced

Groundrush treats a logbook as an input to a competency engine rather than an archive, with sourced requirements, explicit uncertainty, offline use, private-by-default records, and a separate BASE data model. It is not available yet, but the unusually careful thinking about units, privacy, exports, and unverifiable statistics makes this a worthwhile callback.

The Two-Tonne Temperature Problem

August 15’s newborn domains include a live-aboard hydrogen airship with a two-tonne lift problem, a Japanese toolbox that explains its assumptions, an advisory-by-advisory Hawaiʻi hurricane archive, and a wedding-gift game about ungrateful poultry.

This is one of 1,000 discoveries in the 2026-08-15 Domain Arrivals issue.
