Evidence stage
CapabilityA demo, benchmark or paper shows the task can be done. Updates what the technology can do — not what employers will do.
Tasks this bears on
Formwork for concrete
Building and stripping the temporary moulds that concrete is poured into.
Still human-led≈ Platform inference
Finish carpentry and installation
Fitting doors, windows, stairs, ceilings, floors and cabinets, often overhead and in finished spaces.

Where this applies
Denmark. A randomised cross-over field study of 20 carpenters doing overhead tasks such as installing ceiling panels and formwork found a passive shoulder exoskeleton reduced peak shoulder and forearm muscle activity by 3.1 to 9.4 percent but increased low-back activity by 2.3 to 3.4 percent; participants rated usability as good. A worker aid tested on a small group; it does not automate the work.
What this means
Wearable aids can ease the shoulders during overhead carpentry, at some cost to the back.
What it does not yet show
One device and 20 carpenters.
What you can check
Open PubMed record 40633339 and find "20 carpenters during overhead work tasks".
Does it change the assessment?
No — and this stage does not move it either. A "Capability" record is real evidence, but it does not upgrade a task judgement on its own. The 2 linked judgements above stand where they were.
