# Apeiron AP1 – G32D tachyonic branch-boundary preflight

**Updated UTC:** 2026-09-03T09:01:34Z  
**Classification:** `M1_TACHYONIC_BRANCH_BOUNDARY_PREFLIGHT_PASS_G32D_MULTIRESOLUTION_EXISTENCE_AUDIT_OPEN_NEW_HELDOUT_LOCKED_PHYSICAL_KERNEL_BLOCKED`  
**AP1 status:** ORANGE

The G32C-bound log-H recovery pilot stopped before completing its coarse
level.  No pilot report, checkpoint, trajectory, or seed was written.  All
subsequent diagnostics used only the already consumed N<=0.10 domain.

The first-map growth is localized to the tachyonic chi2 channel.  A
paneled non-blind continuation reproduced a contractive positive-H anchor at
N=0.09953125 with source residual
1.8570549054570691e-10 and H=
1.5444790615694082e-07 Mpl.  The next coarse panel at N=0.099609375
reached H=4.6848455123610343e-08 Mpl on its first
iteration and then stopped fail-closed on the second background integration.
This is a single-resolution diagnostic bracket, not yet a physical branch
termination claim.

G32D predeclares a coarse/middle/fine branch-existence audit using both the
log-H chart and the algebraically independent
`u_H=(H/H_reference)^2, H=H_reference*sqrt(u_H)` chart.  All 20 structural gates pass.  The
preflight itself ran zero backgrounds and zero response kernels.

Equations, physics, parameters, counterterms, PV sectors, moving split, mode
transport, ten Picard steps, relaxation 0.9, and all existing gate ceilings
remain unchanged.  The prospective N=0.105..0.12 heldout, production
background, present anchor, physical response kernel, AP2/AP3, curves, fits,
and significances remain locked.
