🔁 Loop One line: Turn “signal → diagnosis → action → review” into a reusable loop system (platform engineering). Core loop: • 📡 Signal: collect (logs, metrics, events, user feedback) • 🧭 Diagnose: analyze and attribute (RCA, correlation) • 🧰 Act: fix, optimize, automate, or add rules • 🪞 Review: retrospect (regression checks, long-term monitoring) Components: • 🚪 PulseGate: ingestion and collection • 🧠 PulseRCA: attribution and explanation • 👀 PulseWatch: continuous watch (regression, drift, alerts) Typical scenarios: • 🔥 Incident loop: Incident → RCA → action items → regression • 💸 Cost loop (FinOps): Spend → attribution → optimization → guardrails • 🧑‍💻 Dev productivity loop: Cycle time → bottleneck → automation → measure
