Working notes from ongoing research — written as the work happens, not after. Exploratory and
work-in-progress by design: single-trajectory experiments, numbers with stated caveats, dead-ends
included. Read them as a record of what was tried and what came out, not as finished results.

Edge filaments follow the magnetic field, so a whole radial–toroidal plane at the divertor target should be a
sheared image of the midplane plane. On Hermes-3 simulations of TCV it is: a rigid toroidal shift finds nothing,
the equilibrium field-line map finds it at zero lag, structures wider than ~5 cm are inherited and blob-scale
ones are not, mean density and momentum arrive later at the sound speed, and a toroidally equivariant linear map
predicts the plate as well as any operator transformer. Three tabs: planes and correlations, a 3-D torus, and a
prediction atlas with a pre-registered ridge-versus-GAOT pilot. Movies, captions, and open questions included.

A self-contained account of the two-shot dataset, LOLA training procedures, representation
choices, rollout calibration, ETKF sensor conditioning, and the physics tests needed before
diagnostic rankings can be interpreted as design guidance.

The complete deck including the blind-transfer protocol and the proposed design-partner
pilot — everything on the public evidence page plus the sections that stay off the open web.

Measured plasma fluxes and a material stack in; coupled transport, surface chemistry,
self-consistent charging, and a moving 3-D profile out. Reproduces a published SiO₂
trench experiment to 0.19% on the mask opening, measured head-to-head speed against the
open-source state of the art, and a preregistered blind-transfer protocol with the held-out
data mechanically sealed. Movies, scorecards, and claim boundaries included.

Four model families — a deterministic ViT operator, a geometry-aware graph transformer,
predictive self-supervision, and latent diffusion — each tried on one Hermes-3/BOUT++ trajectory
of tokamak edge turbulence, scored on physics gates rather than pointwise error. The recurring
enemy is "the freeze": the collapse of MSE-trained models onto the conditional mean.

Given the generative emulator of notebook I, what can a realistic set of edge diagnostics
(gas-puff imaging, divertor Langmuir probes, reflectometry) actually constrain? Anchored rollouts
with synthetic sensors, two misleading signals caught along the way, and a first-pass observability
estimate with its caveats stated up front.
