Original claim text
MUON g-2 SEAM VERTEX (2026-06-15, archive integration of the old muon-g2 note, re-typed for the current kernel): the carrier fixes a second-order topological defect delta_2 = B*gamma*delta_top^2 = (5/4)delta_top^2 (delta_top=Omega_adm c3^4=48 c3^4=3/256pi^4, v2/v23; B*gamma=(3/2)(5/6)=5/4 the carrier compression quotient, v51); the seam-loop projection a_mu^seam = delta_2/(2 pi) = 45/(524288 pi^9) = 2.879e-9. (1) [E] the VALUE is an exact compiler number (trace reading delta_2 = 4! Tr_{S+}(X^2) c3^8, Tr=120=5!). (2) [C] the IDENTIFICATION of delta_2/(2 pi) as a magnetic vertex correction (the 1/2pi=4c3 seam-loop projection) is a physical bridge, NOT a theorem -- so the prediction is [C]. (3) [N] 0.81 sigma vs the dispersive Delta a_mu=(2.49+-0.48)e-9. (4) [C] HONEST: lattice/CMD-3 HVP shrinks Delta a_mu (~1.5e-9), the FIXED TFPT value then sits ~1.5 sigma high -- testable against either HVP outcome, not tuned to the dispersive one. (5) [X] dated kill test: a converged Delta a_mu outside 2.879e-9 +- 0.5e-9 excludes the seam-vertex mechanism (compiler core untouched). A downstream readout, NOT a compiler power. Wolfram-mirrored (the value is exact). (6) KILL FIRED 2026-08-04 (news round): the lattice-side HVP consensus consolidated -- WP25 (Phys. Rep. 2025) adopts the lattice HVP as the SM baseline and the BMW hybrid evaluation (Nature 2026) confirms it, Experiment - SM = 0.5 sigma, i.e. Delta a_mu converged OUTSIDE 2.879e-9 +- 0.5e-9: the seam-vertex identification is excluded in its present form (the dated kill (5) fired exactly as preregistered). The bridge is dissolved; the exact compiler number (1) [E] and the compiler core are untouched -- the watchdog delivered
Original classification detail
Physical bridge KILLED [X] fired 2026-08-04: a_mu^seam = delta_2/(2 pi) = 45/(524288 pi^9) = 2.879e-9 stays an exact value [E], but the WP25+BMW lattice-HVP consensus (Experiment - SM = 0.5 sigma) puts the converged Delta a_mu outside 2.879e-9 +- 0.5e-9 -- the [C] vertex identification is excluded in its present form; bridge dissolved, compiler core untouched; not a compiler power

- =150 2026-08-04 (LVIII) (the news round: a pure data-refresh against the August-2026 literature — no new analysis of our own, honest in both directions. CONFIRMING: JUNO's Neutrino-2026 update ( [formula in source] days) lands at [formula in source] — the sharpest single measurement of the solar angle, [formula in source] from the frozen prediction [formula in source] , central value moving toward it from the [formula in source] -day run; ICARUS's first standalone result (no [formula in source] disappearance, new [formula in source] exclusions at [formula in source] CL) adds another sterile null exactly as [formula in source] requires; the sequentially-valid DESI reanalysis localises the evolving-dark-energy signal almost entirely in the LRG2 bin (without it the evidence collapses, mildly pro- [formula in source] CDM — the dissolution trend the [formula in source] watchdog predicts); two new independent birefringence analyses ( [formula in source] constant-model-preferred; PR4 field-level [formula in source] ) stay consistent with the [formula in source] seed; CMB-SPA [formula in source] lands [formula in source] from the parameter-free budget [formula in source] (correlated legs, never a new independent hit). WEAKENING, equally prominent: CMB-SPA (SPT-3G D1 [formula in source] ACT [formula in source] Planck) gives [formula in source] — the central value sits above the TFPT band edge [formula in source] for the first time (edge at [formula in source] , preferred branch [formula in source] at [formula in source] ; not yet the dated kill ``robustly [formula in source] '', typed an honest mild weakening, scorecard row tension [formula in source] watch-flag); the DESI DR2 effective-mass posterior keeps the [formula in source] \,eV floor under [formula in source] model-dependent pressure (unchanged, on record). ONE BRIDGE DIES: the muon [formula in source] seam-vertex bridge's dated kill condition (2026-07-02) has FIRED — WP25 (Phys.\ Rep.\ 2025) adopts the lattice HVP as the SM baseline and the BMW hybrid evaluation (Nature 2026) confirms it, experiment [formula in source] SM [formula in source] , so the converged [formula in source] lies outside [formula in source] : the vertex identification is excluded in its present form, the scorecard row is typed kill_channel, ledger FR.MUONG2.01 carries the dated kill note, and tfpt_4_frontier gets the dated update paragraph [formula in source] summary-table move [formula in source] \ on the bridge — the exact compiler number [formula in source] and the compiler core are untouched (no core marker moves): the watchdog delivered exactly what it was built for. OPERATIONAL: the Vela GO-programme preregistration is FROZEN as experiments/p9-forecast/hypotheses/p9_go_programmes_v1.yaml ahead of the expected 2026/27 giant-glitch window (no glitch since 2024-04-29; long-component decision rule and the [formula in source] -TOAs/day cadence requirement inside; draft SHA recorded as provenance); CHIME/FRB Catalog-2 [formula in source] RepCat4 data-availability notes recorded in repeater-cascade and frb-ontology.

the muon anomalous magnetic moment a_μ=(g_μ−2)/2 as a seam vertex readout ([C] downstream, NOT a compiler power; archive integration of the old muon-g2 note). The carrier fixes the second-order topological defect δ₂=B·γ·δ_top²=(5/4)δ_top² (δ_top=Ω_adm c₃⁴=48c₃⁴=3/256π⁴, v2/v23; B·γ=(3/2)(5/6)=5/4 the carrier compression quotient, v51); the seam-loop projection a_μ^seam=δ₂/(2π)=45/(524288π⁹)≈2.879×10⁻⁹. [E] the VALUE is an exact compiler number (trace reading δ₂=4!·Tr_{S⁺}(X²)·c₃⁸, Tr=120=5!); [C] the IDENTIFICATION of δ₂/(2π) as a magnetic vertex (1/2π=4c₃ seam unit) is a physical bridge; [N] 0.81σ vs dispersive Δa_μ=(2.49±0.48)×10⁻⁹; [C] HONEST: lattice/CMD-3 HVP shrinks Δa_μ (~1.5×10⁻⁹), the FIXED value then ~1.5σ high; [X] dated kill test: a converged Δa_μ outside 2.879×10⁻⁹±0.5×10⁻⁹ excludes the mechanism (core untouched).
