The Double-Slit Without Mystery: Tick Counting in the Packet's Own Frame

"Double-slit" é o termo correto em inglês — experimento de fenda dupla. "Dual" seria errado nesse contexto (dual slit soa mais como "fenda dual" no sentido de "duas faces da mesma coisa", o que não é o experimento). Description para o Zenodo do Double-Slit v1.2 (DOI 10.5281/zenodo.19673003): The Double-Slit Without Mystery — Tick Counting in the Packet's Own Frame (v1.2) Version 1.2 — Metadata Update, Phase 2 Post-Synthesis (2026-04-23) This revision is metadata-only. No content changes to the paper body: axioms, postulates, the six-piece structural account, falsifiability clauses, and all four open problems are preserved identically to v1.1. The update brings the paper into alignment with the Phase 2 post-synthesis revisions of the program's parent papers: Discrete Time v2.0, 1905 vs 2022 v2.0, and Agency v3.0 (all under unchanged DOIs). The Structure of the Present (DOI 10.5281/zenodo.19711475) is added to the parent paper list as the consolidated ontological synthesis. Paper content (preserved from v1.1): The double-slit experiment exhibits no wave-particle duality. The statistical pattern on the screen differs between the "no detector" regime (OFF) and the "which-path detector" regime (ON) because the packet traverses a different number of discrete resolution events — ticks — in its own frame. The packet is always the same discrete object. What changes is the count of ticks in the packet's own history: OFF is a two-tick history (emission, absorption at screen); ON is a three-tick history (emission, forced detector interaction, absorption). The detector tick fragments the global geometric constraint into two local segments, which is the mechanical counterpart of the categorical shift in the statistical pattern. Weak-measurement "gradual" loss of interference is not a continuous intermediate regime of nature. It is a mixture of two discrete populations (two-tick packets and three-tick packets) whose proportions are set by the coupling strength of the intermediate apparatus. The Englert envelope V² + P² ≤ 1 is the correct coarse-grained description of this population mixture — an accounting identity over populations, not a statement about continuous partial nature within any individual packet. Direct-observation support comes from microscopy of Structured Vesicular Entity aggregates: partial engagement between particles is never continuous at the individual level. The delayed-choice quantum eraser (Kim et al. 1999) does not require retrocausality. In each photon's own frame on a null worldline, origin and detection are coincident, so the laboratory-frame ordering ("signal detected before idler choice") has no causal force on the packets themselves. The correlation was established at the down-conversion node and is read, not produced, at the two detection nodes — the same separability-failure move established in 1905 vs 2022. Four open problems are explicitly flagged: OP1 (first-principles derivation of OFF-regime interference distribution), OP2 (formal derivation of the spin-rotation mechanism at forced nodes), OP3 (characterization criterion distinguishing apparatus ticks from environmental noise), OP4 (extension to many-body interference and matter-wave interferometry). Audit record (v1.2): Parallel independent audit noted a divergence between DS (recommending the present metadata-only update) and GMN (recommending a v2.0 cosmetic update with a Minkowski-from-G_past refinement of Piece Three). CL integrated as editorial lead and MF adjudicated in favor of v1.2. GMN's point is registered as a potential trigger for a future v2.0 should OP1 be advanced or another substantive trigger emerge.
