The useful parts around the qubit
A clock needs a reference it can follow. A connection needs somewhere for information to wait. A measurement needs an amplifier, and a quantum processor needs the rest of the computer. Five source-led stories make the hidden jobs visible, while keeping measured results, manufacturing programmes and exploratory plans distinct.

For a clock: an independently built comparison. For a link: a useful operation across modules. For an AI laboratory project: a released evaluation that includes gain, noise, stability and all attempts. A routine source check is not a new scientific result.
