MictlanX: Elastic code-defined object storage system

Modern object stores expose only coarse, static configurations (replication factor, ACLs, bucket lifecycles) and must be over-provisioned to absorb demand spikes or new security requirements. MictlanX upgrades the storage layer itself with two code-defined programming models: a Responsive-Deployment Model, that lets operators declare elastic regions in YAML/Python, and an Adaptive Data-Placement Model, that drives per-object filters and dynamic replication. A 16-node prototype sustains 20 MB/s under a 0.01s burst while keeping 90% of requests below 0.1s---up to 4× faster than fixed-replica modes---and beats MinIO, Google Drive, and Dropbox by up to 23% throughput with sub-second latencies.
