Signals Shipped
Technology tokens on the changeset, matched against what each specialist declares. Free, instant, and the reason a large roster is affordable.
Each file in the changeset carries signal tokens derived from its extension and location. Each specialist declares the signals it reviews for. A specialist whose signals match is in, with no judgment involved and no cost incurred. This is the mechanism that lets devteam carry a large roster without every run paying for all of it.
The always-on floor sits alongside it
Some concerns do not belong to a file type — architecture, code quality, development process. Those specialists are marked always-on and skip both signals and the poll. They are also where most of the token spend goes, so always-on is deliberately rationed.
