New results that could move the volume's weaknesses.
The volume's weak-points page names the gaps. This page names the evidence that might close them. Most entries will start as watching and only move to promising once the citation, replication, and relevance are clear.

ConfirmedA rice-sized chip-based microresonator coupled to a larger optical-fiber loop produces a stable, self-starting microcomb whose evenly spaced optical lines are converted into multiple precisely spaced millimetre-wave signals at once. Individual comb lines can be amplified or suppressed, and the comb's precision and stability carry through to the millimetre-wave output — it holds while people jump next to the bench.

Chapter 20 · engineered surplus · precision timing
What would change
Supplies Chapter 20 with a manufactured instance of the profligacy the chapter tracks: spectral surplus whose spacing and amplitudes are chosen rather than inherited. It changes no claim about gravity, curvature, or emergent geometry.
What still needs checking
Comb linewidth and phase-noise figures against atomic-clock references; how much of the demonstrated stability survives outside the tabletop setup; and whether the shoebox-scale, satellite, and 6G applications named in the coverage reach a working device.

ConfirmedA computational fluid dynamics integration of the Navier-Stokes equations around a wing, producing pressure fields, lift, and trailing-edge vortices in slow motion. The post frames the result as something that was not photographed but computed: the flow was 'solved' rather than filmed.

Chapter 4 · visualisation as proxy · Navier-Stokes status
What would change
Reinforces Chapter 4's central point that a rendered flow field is a picture of a solution, not a photograph of the thing. It gives the chapter a concrete, widely accessible example of the 'solved but never filmed' distinction and the proxy status of beautiful visualisations.
What still needs checking
Whether the specific simulation is an original computation or a reproduction of a published case; the Reynolds number, turbulence model, and boundary conditions used; and whether the phrase 'never filmed' is strictly true (smoke-tunnel and PIV wing visualisations exist) or a rhetorical contrast between direct optical observation and numerical solution.

ConfirmedA demonstration of an electromagnetic wave negotiating a sharp 90-degree turn inside a photonic crystal. The repeating dielectric lattice opens a frequency range in which bulk propagation is suppressed; removing a line of scatterers creates a defect waveguide that confines and steers the field along the allowed path.

Chapter 3 · eigenvalues interleaf · metamaterial anchors
What would change
Reinforces the anchor status of photonic and optical metamaterials in Chapter 3's analogue table. It does not move the gravitational claim, but it supplies a clean, visual example of band-structure engineering producing geometric function inside its proper validity band.
What still needs checking
Whether the demonstration is an original simulation or a reproduction of a published geometry; the lattice parameters, refractive-index contrast, and frequency regime; and whether the source can point to a peer-reviewed reference for this specific bend structure.
Research on matter formation
New work from Berkeley appears to bear on how matter forms in the regimes the volume tracks. The exact paper, group, and claim are still being verified; the entry is held as a placeholder until the citation and result can be stated precisely.
Touches
Chapter 3 · Chapter 16 · Chapter 17 · gravitational metamaterials
What would change
If the result provides a laboratory or observational anchor for engineered effective-mass systems, Finding 01 (no direct experimental anchor) would need to be narrowed or retired. If it instead strengthens the analogue-gravity picture in another wave system, it would be filed as a proxy, not an anchor.
What still needs checking
Full citation (authors, title, journal/preprint, date), the exact system studied, whether the effect is gravitational or an analogue in a different medium, and whether the result has been independently reproduced.
