aci-sim is a stateful REST simulator of a 2-site Cisco ACI fabric (per-site APIC + ND/NDO management planes) — for testing ACI automation (Ansible cisco.aci / cisco.mso, aci-py, custom REST clients) and CI gates without real hardware. Highlights: APIC + NDO REST surface served from one in-memory MIT built from a declarative topology.yaml; port mode + sandbox (real per-device IPs on :443) run modes; LLDP/CDP neighbor visibility; NDO->APIC deploy mirror (multi-site templates materialize onto the target sites' APIC stores); real-APIC fvBD default attributes; file-backed state save/restore; an `aci-sim` CLI (validate/show/graph/run/new/init/lldp); and an 888-test suite. History squashed for the public release. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
