Abstract
Abstract Counterfeiting has emerged as an increasingly severe global concern, posing significant threats to the security of individuals and society. In this study, a series of multilayered information‐encrypted composite materials is developed by embedding a chiral nematic cellulose nanocrystal ( cn ‐CNC) film inside a shape‐memory polymer (SMP) matrix to produce pressure‐responsive photonic crystals. The design also incorporates a cellulose acetate film, as a thermoset information carrier, and graphene oxide (GO), as a secrecy filter. In its initial state, the composite shows no information, while a pattern becomes visible to reveal the information upon hot‐pressing, due to the region‐dependent differences in its photonic responsiveness caused by the rigid pattern. A discernible mark remains even after recovery, serving as tangible evidence of the decrypted information. Moreover, the high color fidelity of these materials is confirmed using reflectance spectroscopy and color analysis over multiple cycles, demonstrating their potential in cyclic information encryption. By harnessing thermal and mechanical stimuli for anti‐counterfeiting purposes, these composites diversify the strategies available for information encryption.

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 it
