Abstract
The analysis of suit[2]-, suit[3]ane and tetrafould [2]-rotaxanes on the bases of calix[4]-arene with the help of the "mechanical disconnection operation" show that these structures possess only one mechanical bond, which is suggested to be called bi-, tri-and tetrafurcated one, respectively, since such structures bear two, three and four divergent mechanical entanglements.In the same time, introduction of the external bulky groups to these structures transforms such unique mechanical bonds into several single ones.There can be several different invariants which have only one mechanical bond, but possess different number of the intrinsic mechanical entanglements like, for example, in [2]-catenane and doubly braided [2]-catenane.The mechanical bond in the last case is proposed to be called the tight one.The constrictive bonds in carceplexes are classified as the spherical mechanical bonds.Thus, the whole classification of the mechanical bonds (together with the previously proposed ones), is presented.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
