Kit-State Lifecycle: A Reversible Modal-to-Actual Bridge for Dynamical Energy Bookkeeping

The Kit-State Lifecycle (KSL) is presented as a reversible, bidirectionalmodal-to-actual bridge over one constrained dynamical inventory. The workingpaper distinguishes quantum-modal and classical-instantiated descriptions;formalizes typed Quantum Kit Budget Unit (QKBU) and Classical Kit Budget Unit(CKBU) bookkeeping; develops constrained Hilbert sectors, operator-derivedcandidate classical sectors, spectral eligibility, a gap-gated instantiationcondition, a context-indexed singular-actualization register, vectorconservation, and one invertible accounting kernel on the complete state. Worked limits establish exact unitary evolution when bridge and environmentalchannels are inactive, standard pure dephasing when the environmental channelis retained, an information-preserving selector reproducing Born frequencies,a finite contextual map attaining the singlet CHSH value while preservingno-signaling marginals, event-level conservation requirements, and theNewtonian limit of a selected-source gravitational equation. The paper alsodevelops a conditional four-form bridge-flux treatment of vacuum energy and asequestered gap-selector normal form for a positive relaxed source. The finite Born and Bell constructions import the stipulated quantum measureand do not yet constitute a Lorentz-covariant causal bridge law. Microscopicderivation of the selector, conserved high-compression source map, bridge-fluxnormalization, proper-time spectral scale, radiative protection, andparameter-frozen empirical discriminants remains the central researchprogram. Version 1.8.1 corrects the reduced-Planck-mass exponent in thesequestered selector, context-indexes the actualization register, sharpens theBell, covariance, and Bianchi-conservation boundaries, externalizes all 50references into structured BibTeX, and adds reproducible archival preflight,metadata, font, Unicode, checksum, and Zenodo support.
