Abstract
Poly( N, N -dimethylaminoethyl methacrylate) (PDMAEMA) with a β-cyclodextrin (β-CD) at the chain end was synthesized via atom transfer radical polymerization (ATRP); poly(ε-caprolactone) (PCL) with a −C═C– segment and an adamantane (Ada) group at two ends, respectively, was prepared through ring-opening polymerization (ROP), and poly( N -isopropylacrylamide) (PNIPAM) with a −S–C(S)–S– segment, which can be converted into a thiol group, was yielded by reversible addition–fragmentation chain transfer polymerization (RAFT). A supramolecular triblock stimuli-responsive copolymer PNIPAM- b -PCL- b -PDMAEMA having good biocompatibility with PNIPAM and PDMAEMA hydrophilic segments and PCL hydrophobic segment was constructed by thiol–ene Michael addition and host–guest interaction. The triblock copolymer could self-assemble into vesicles and respond to carbon dioxide (CO 2 ) gas and temperature reversibly. Under the stimulation of CO 2, the vesicular assemblies swelled obviously; while raising the temperature from 25 to 40 °C, the assemblies displayed a conversion between vesicles and spherical micelles.

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
