Cloudflare + Smarter Feedback

A fourth cloud joins the canvas — build on Cloudflare’s developer platform alongside AWS, GCP, and Azure — plus focused per-node AI feedback and a round of security, reliability, and simulation-correctness hardening.

• Cloudflare provider: Workers, Queues, D1, and R2 — full rulebooks, validation, simulation, service-binding IAM, and Terraform export (with $0 R2 egress in cost estimates)
• Per-Node AI Feedback: select any node for provider-aware best-practice, cost, and reliability guidance — cached, rate-limited, with an offline rule-based fallback
• Security: diagram ownership now derives only from the session cookie and the public share-link read no longer leaks the owner’s internal user id; every IaC config value is escaped so exports can’t be made to inject foreign resources
• Reliability: Collaboration and Simulation Durable Objects now survive hibernation cycles; the simulator stops doing work when no one is watching
• Simulation correctness: fault error-rate is applied once (not squared) and throughput now propagates through cycles; plus a Playwright canvas harness covering build → simulate → export
