04 · Where it becomes complicated
A streak can support the behaviour it was designed for. It can also slowly replace it. The person may begin protecting the counter rather than pursuing the original goal. The mechanism is useful precisely because it is powerful — and that makes the design question more interesting.
When does a tool for consistency stop serving the behaviour and become the behaviour itself?
05 · What this tells us
Good behavioural analysis is not a list of tricks to copy. It asks what a mechanic changes, who benefits from that change, what the user believes they are doing, and what might happen over time.
That is the kind of question WholeArc Labs wants to keep investigating.
