This revised version of MetaTime XI reframes the manuscript as a phenomenological non-Markovian hypothesis for intermittent observability in residual multimodal anomaly data, rather than as a mature effective field theory. The central proposal is that a subset of apparently extreme telemetric discontinuities may be better modeled not as continuous inertial transport of a solid body through air, but as intermittent occupation of the observable layer by a latent structure, producing large apparent accelerations through occupancy switching rather than persistent propulsion. Compared with the previous version, this manuscript now distinguishes more explicitly between four competing model classes: continuous transport, memoryless sensor dropout, Markov-switching hidden-state models, and non-Markovian memory-kernel models. It introduces explicit history dependence both in the observation process and in the environmental response, strengthening the non-Markovian interpretation beyond simple intermittency. The paper also adopts a more conservative thermodynamic language: Landauer-type terms are treated as heuristic bookkeeping rather than as direct physical constraints unless the substrate, coarse-graining, and relevant temperature can be independently specified. The revised version further clarifies ordinary confounds such as sparse sampling, radar dropout, sensor-fusion failure, and geometric misreconstruction, and sharpens the falsifiability program by defining comparative kill-tests for multimodal anomaly cases. The result is a more precise and more modest manuscript: not a universal explanation of UAP, but a testable phenomenological framework for distinguishing intermittent observability from ordinary tracking failure and from continuous transport models in future metadata-rich cases.
