Strong events, ranked roles, and a chain without a circle: manuscript, frozen artefacts, and the deployment contract

This deposit is the fifth paper in a series on task-required motor events: themanuscript, its figures, and every frozen artefact needed to re-derive its numbers. It asks which points of a movement are required by the task and which are contributed bythe person. The answer is a procedure — turning points ranked by persistence, ordered byarc length, then asked which ranks recur — plus a contract for running two instrumentstogether without either being silently wrong: a geometric examiner that defines andaudits the object, and a causal network that supplies only a relative readout. Thecontract is measured rather than asserted. A 20 ms low-pass removes 22% of the examiner'slabels and leaves no trace in its output, and the network does not move at all when thathappens, so it cannot serve as a check. What can be built is a self-audit on theexaminer's own output, and Appendix E gives its measured range and the two conditionsoutside it. What travels is the procedure, not a list of names: ten roles recur in all three cohorts,seven of them within 39 degrees of the same phase, while the count of task-required rolesmoves from 18 to 15 to 20. Sit-to-stand keeps the procedure and loses the circle — achain with no closure and no phase coordinate, whose rise and sit-back share zero events. The source recordings are not redistributed. Each number is a transcription of a frozenJSON, PROVENANCE.json pins every artefact, generator and protocol hash, and six gates withself-tests check the manuscript against them.
