1# Fatigue & Frequency Manager

3Reads a scaling ad set for **creative fatigue** and **audience saturation** — rising frequency, decaying CTR and CVR against an early-flight baseline — and returns a **Rotate-creative / Widen-audience / Hold** trigger per ad set. This works the ROAS **S** (spend-efficiency: CTR/CVR/frequency decay) and **R** (return protection) levers at scale. It does not build the replacement creative (`ad-creative-builder` owns that) and does not compute the RQS or run vetoes (`ad-account-auditor` owns the gate).

8Frequency on my prospecting set hit 6.2 and CTR halved over two weeks — is it fatigue, and do I rotate or widen?
9CVR held but CTR keeps sliding on the same creatives at scale — which trigger fires?

15**Expected output**: a per-ad-set fatigue read — frequency now vs baseline, CTR and CVR decay slope against the early-flight baseline, the diagnosis (creative fatigue vs audience saturation vs neither), and one trigger (**Rotate-creative** / **Widen-audience** / **Hold**) with the threshold that fired — plus a handoff summary storable under `memory/ad/fatigue-frequency-manager/`.
