Planetary Electrical Release Across the Solar System

msf:48335 v2.0 rebuilds the archival msf:48300 planetary-discharge framework using modern mission evidence and a stricter baseline-first methodology. The central conclusion is that electrical and magnetic release phenomena across the Solar System share a common system-level architecture: environment-specific drive → separation or energy storage → local threshold → release → environment-specific observables. The microscopic mechanisms are not universal. Mars now provides direct in-situ evidence of triboelectric micro-discharges. Perseverance detected 55 electrical events associated primarily with dust devils, convective fronts, and localized turbulent particle motion. Earth remains the calibrated atmospheric reference, with mixed-phase cloud electrification, Maxwell fields, streamer and leader development, and post-breakdown electromagnetic response owned by the terrestrial atmospheric-electricity framework. Venus remains a candidate or contested lightning environment. Laboratory discharge experiments in Venus-relevant CO₂–N₂–SO₂ mixtures nevertheless demonstrate rapid sulfur chemistry, including reactive sulfur species and stable S₈ and H₂SO₄ products. Jupiter provides both deep lightning and a distinct shallow-lightning branch involving ammonia–water thermodynamics. Saturn provides confirmed optical and radio lightning in deep convective storms. Titan acts as an important weak/no-lightning control: atmospheric conductivity and a 36-Hz ELF signal were measured by Huygens, but ordinary lightning remains weak, absent, or unconfirmed. The Sun is included as a deliberate out-of-domain comparator. Solar flares are governed by magnetic free-energy release and reconnection rather than neutral-gas electrical breakdown. Paschen scaling is therefore retained only as a local uniform-gas reference. It is not treated as a universal planetary-lightning law. For each environment α, the standard physical state is represented by a declared vector z_α containing appropriate measured or constrained quantities such as composition, pressure, temperature, phase, conductivity, charge density, electric and magnetic fields, chemistry, drive, and geometry. A USP transfer representation may be written schematically as: Δf_env F(z_α, ∇z_α, ∂t z_α). This quantity is an operational representation rather than a universal physical frequency. If Δf_env is derived entirely from the same conventional inputs already used by the baseline model, it contains no additional physical information. A genuine USP contribution requires an independently measured observable or independently fixed prediction beyond the conventional state ledger. The exact additional-physics null remains: A_USP = 0. No nonzero Level-D USP residual is claimed in msf:48335 v2.0. The principal scientific value of the manuscript is therefore cross-environment transfer: testing whether a frozen representation can remain useful across radically different planetary conditions without erasing the standard physical mechanisms that distinguish them. This version also supersedes the archival msf:48300 identifier and eliminates the overlap between the former msf:48300 framework and the active msf:48335 reconstruction. The earlier identifier is retained only for archival traceability; all current claims, equations, evidence classifications, and validation procedures belong to msf:48335 v2.0. *SHORT ZENODO SUMMARY A cross-environment study of electrical and magnetic release across Mars, Earth, Venus, Titan, Saturn, Jupiter, and the Sun, showing that the common structure is threshold release rather than one universal microscopic lightning mechanism. USP is restricted to calibrated transfer and residual testing under the exact null A_USP = 0. The active msf:48335 reconstruction supersedes archival msf:48300 and removes overlap between the two identifiers while preserving the earlier framework for historical reference.
