Chronometric frontier v2.1: resolve compact-object no-go and build the first real interacting two-time solver

[terrorproforma]

The adversarial v2 evidence repair is merged. The next frontier is now defined by actual blockers rather than preflight labels.

Gate 1 — cosmology versus neutron stars

The archived low-f_a ridge meets the spherical conversion criterion for neutron stars. Complete one of the following with explicit field equations and binary-pulsar observables:

• a demonstrated compact-object screening/scalarisation branch;
• a two-spurion architecture separating transient cosmological focusing from the late QCD coupling;
• a different vacuum-selection mechanism that preserves nonzero chronometric shear without q_NS > q_conv.

No cosmological viability claim may be restored before this gate closes.

Gate 2 — complete portal transport

• finish the hard Yukawa-assisted 2<->2 cuts;
• pointwise subtract hard/soft/LPM overlap;
• benchmark Bethe-Heitler and deep-LPM limits;
• propagate scale, quadrature and model uncertainty;
• compare integrated rates against the fully recomputed v1.5 LPM anchor.

Gate 3 — real interacting unequal-time evolution

Before a non-Abelian 3PI pilot:

• implement a self-consistent scalar/Yukawa 2PI Kadanoff-Baym unit tier;
• derive equations from the declared functional rather than loading result tables;
• demonstrate timestep, momentum, cutoff and memory convergence;
• verify commutators, KMS/FDT and energy conservation;
• then promote the same tested storage/integration architecture to PT/BFM gauge fields and dynamic vertices.

Gate 4 — UV completion

• specify the 24-link local gauge/deconstruction matter content;
• prove continuous-gauge, mixed, discrete and gravitational anomaly cancellation;
• integrate out messengers and calculate the first winding operator;
• show no lower-dimensional gravitational or nonlocal operator exceeds the protected Z6 potential.

Gate 5 — publication

Prepare the narrow formal/threshold manuscript only after:

• specialist novelty and priority review;
• independent reproduction of the v2 evidence suite;
• explicit separation of established QCD threshold physics from the project-specific chronometric interpretation.
