Loop Walking Cascadia: a Triangle Lattice, its Rogues and Witnesses, and One Opening of the Vault

A GPS network is a team of witnesses, and some witnesses lie steadily. Standard quality control catches three kinds of bad testimony — sudden jumps, wild outliers, and flatlines. There is a fourth kind that passes all three checks: the station that drifts slowly, smoothly and coherently, because slow coherent drift looks exactly like tectonics.

This paper builds a cheap instrument for catching that fourth kind, and then spends the rest of its length finding out what else the instrument can and cannot see. Lay a triangle lattice over the network, read each triangle's phase circulation as an integer, and a drifting station betrays itself twice over: its triangles light up with persistently one-signed charge, and its phase winds against every quiet neighbor with the same sign, year after year. The instrument is coordinate-free and magnitude-blind by design — it counts windings, it does not measure displacement.

The work is deposited as a two-part paper with its full apparatus. Part I is a registered campaign: a question frozen in advance, a sealed data era, a one-shot vault opening, and a precursor search that ended flat and is published flat. Along the way it reports a silent traveling front caught twice in the training record at slow-slip speed, a standing dipole that four separate instruments failed to convict of any instrumental cause, and a standing spatial texture that held its configuration blind through the vault wall. Part II reframes the margin as a pachinko board — the crust's inherited structure as fixed pins, the individual outcome unpredictable and the accumulated pile stable — and puts five pre-registered tests to it. The board channel comes back loud and the flow channel comes back a whisper; both verdicts are reported, and one of the five tests broke on its own null and is printed as broken, exemplars included.

The paper ends on a second sealed registration: five predictions about weeks the design has never touched, frozen by name against the lists deposited here, with fixed scoring windows so that neither the authors nor anyone else can peek repeatedly and publish the favorable pull. They ship deliberately unscored. Everything needed to score them independently is in this record.

The deposit includes the paper, all sixteen figures, the frozen registration protocols in both versions the paper cites by checksum, every analysis tool with its launcher, the runs of record the paper cites by name and timestamp, the full 228-card per-station scorecard deck, and two interactive HTML explorers. Every claim in the paper names the run that produced it, and every run in this crate can be regenerated from the tools beside it.
