"Loop engineering" consolidated as a name this week, and two repos are carrying it.

cobusgreyling/loop-engineering (9,917 stars) ships loop init (emits a 10-100 "Loop Ready" score), loop audit, loop doctor (audit plus drift detection, returns your top three actions), plus loop-cost, loop-context (stateful memory with a circuit breaker), loop-gate and loop-sandbox. It formalizes a three-stage autonomy ladder (L1 report, L2 propose, L3 unattended) and names "intent debt," the comprehension gap that accumulates as loops grow and nobody remembers why a given gate exists. Separately huangruiteng/loopx took +854 stars in a day for durable goals, typed todos, peer claims and quota-aware scheduling across 200+ hour trajectories. The circuit breaker and the cost estimator are the two pieces most hand-rolled loops are missing.
