We refer to this phenomenon as "the Déjà vu effect," and suggest that understanding its significance may shed light on how organisms colonize underutilized or empty ecospace, the establishment of the mixed layer, and the temporal and spatial distribution of matgrounds. These recurrent trace-fossil assemblages record the activity of the epifauna and a very shallow tier infauna, in the absence of mid- to deep-tier trace fossils and mottled textures. They typically consist of grazing trails, very shallow feeding burrows, and arthropod trackways. Shallow-tier burrows and trails with well-developed scratch marks may be present. These ichnofaunas suggest that the initial exploitation of underutilized or empty ecospace is linked to a set of recurrent behavioral strategies to obtain food from matgrounds and firmgrounds in the absence of a well-developed mixed layer. Preservation of these behaviors in the form of trace fossils is mediated by a set of taphonomic conditions. These taphonomic windows occur during the initial colonization of empty or underutilized ecospace, such as the Ediacaran-Cambrian transition or the subsequent colonization of the land, but also after the end-Permian mass extinction, which may have had a negative impact on the mixed layer in marine environments, producing a return to the ecologic conditions of the early Paleozoic.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
