Worldline Resonance and Quantum Causality Decoding: From Time-Resolved Interference to Ideal Causality

Worldline Resonance and Quantum Causality Decoding: From Time-Resolved Interference to Ideal Causality (세계선 공명과 양자 인과 해독: 시간분해 간섭에서 이상적 인과로) Quantum Causality Decoding (QCD) seeks to recover the causes of ideal outcomes in other Everett-relative histories from time-resolved interference and implement those causes in the present world. Its third-generation principle replaces complete-wavefunction reconstruction with task-relevant decoding of the measured record, while retaining the original objective. We formulate the complete chain of residual coherence, resonance, receiver access, causal identification, ideal-history selection and objective-preserving intervention in one framework. Two explicit quantum realizations supply complementary constructive results. In a native excitation-preserving network, intermediate occupation events are recorded by retained environmental pointers; the actual receiver signal is derived as C_k = η^k (exp(-i J k τ))_11. A corresponding oscillator realization cancels an unknown repeatable background by differential local displacements. Structured time-record inversion determines the native mechanism and recording strength without an answer table or physical inverse evolution. A second, reversible event architecture covers arbitrary finite Boolean mechanisms and computes protective actions rather than supplying them to the decoder. General causal-kernel recovery, finite-data bounds, candidate-selection margins, robust control, and source-present transfer are proved with their respective physical premises. A unified composition theorem bounds actual joint failure by inference, control, transfer and objective-coverage errors. Synthetic records, explicit retained-pointer calculations and failure cases accompany the proofs.
