Loop watches every primitive you run, every output you ship, and every post that lands. Then it tells you what's working, what's not, and what to try next.
You make the thing. You post it. Engagement comes back. Some of it lands. Some of it dies. You feel the difference but you don't actually know which inputs caused which outputs.
Loop fixes that. Every primitive you run gets logged. Every post you publish gets watched. When a pattern emerges, Loop tells you, and offers to update your Style profile so the next run inherits what worked.
Content is exhaust. The system is the product. Loop is how the system learns.
Loop sits behind every other primitive. You don't import anything. You don't configure anything. It just watches and reports.
A working production system needs a working feedback signal. Loop is that signal.
Loop is the feedback layer for everyone running the CGA system. If you have a Producer account, Loop is on. No upgrade, no add-on.
