Recent experimental realizations of the Einstein–Bohr recoiling-slit thought experiment have demonstrated a continuous tradeoff between interference visibility and recoil-induced distinguishability, often interpreted as a definitive empirical vindication of Bohr’s complementarity principle. In this work, we propose an alternative but compatible interpretation in which the effective geometry of distinguishability is induced by the experimental context itself. By introducing a context-dependent metric operator on the slit’s motional Hilbert space, we show that the standard recoil-limited visibility law emerges as a limiting case, while allowing for experimentally testable deviations when coherence bandwidth and accessibility constraints are varied. This formulation preserves complementarity while reframing its enforcement as a mechanistic, geometric process rather than an axiomatic postulate.
