☀️🌑 Eclipse 2026 — the sky writes geometry, and geometry cannot lie

On August 12, 2026 at 17:45:54 UT, the Moon's shadow — a cone almost 380,000 km long with a tip 294 km wide — drags across the Earth at supersonic speed, over western Iceland and northern Spain. This repository is the complete, public, falsifiable record of an experiment that reads that moment as a three-dimensional shape, not a number — its claims sealed 27 days in advance, its data drawn only from public archives, its verdicts computed in exact integers. No code lives here; this is the experiment's own surface, and its data tables are generated by the substrate from its own ledger.

The realization

Sixty to a thousand kilometers up is a second sky — the ionosphere, the charged shell GPS travels through and aviation radio bounces off. When the shadow cone pierces it, the shell answers with a moving dent: charge collapses 20–60% under the footprint and refills behind it. For sixty years, science measured that dent with a ruler: "TEC dropped 40%." But rulers can be fooled — on May 11, 2024 a geomagnetic superstorm dug deeper dents than any eclipse, at every station, under an unobscured Sun. Every ruler-pipeline running that day recorded an eclipse that never happened.

The substrate reads the dent as shape: the response either threads the shadow's own timetable — confined to the exact minutes the geometry names, deepest within seconds of each station's own maximum, marching station-to-station at the cone's ground speed — or it does not. Linked or not linked: an integer, no maybe. A storm can dig a deeper hole; it cannot thread the ring. It has no cone, no track, no clock.

Because shape cannot be counterfeited and shape-verdicts are exact, one machine sealed to-the-second claims about the sky 27 days before the sky moves — including a verdict that stays decidable through a superstorm — and anyone on Earth can check them against the same archives on August 13.

How this stays true

The generating substrate lives elsewhere; after every ingest or verdict it regenerates the marked blocks in these pages from its ledger, and a drift gate proves the wiki matches the data byte-for-byte. The prose frames; the substrate speaks its own numbers.

Resolves 2026-08-13 — the verdict, pass or fail, lands in these same tables. The historical record already publishes its own falsifiers, because a recorded failure is how this experiment learned to see.
