holos.dev is a development surface for holistic system design — a single interface to observe, traverse, and reshape architectures from microservices to monoliths. No marketing gloss. No friendly abstractions. Just the topology, exposed.
Static and runtime sources fold into a single graph. Each node preserves its provenance trace; each edge carries its protocol envelope. Nothing inferred is unsourced.
Every interface is a contract. holos.dev surfaces the raw protocol surface of each boundary — schemas, error envelopes, retry posture, idempotency keys — with no editorial layer.
Telemetry overlaid directly onto the topology — saturation, error rate, p99, queue depth. Signals are not aggregated into vanity scores. Each channel can be read in its native shape.
Trace every event from origin to outcome — across asynchronous boundaries, replays, and partial failures. The lineage is a first-class object you can query, fork, and compare.
