go.mod declares the module path (github.com/JustinZeus/spreadlab); every
import inside the repo is spelled relative to it. Layout follows the
standard Go shape: cmd/<binary>/main.go per executable, internal/ for
packages other modules may not import (the compiler enforces this).
No engine code yet, just a placeholder main that proves 'go build' works.

+# spreadlab
+
+Self-hosted dashboard that runs an agent-based deepfake-spread model live:
+change the levers, watch the spread, and (later) search for the best
+intervention under a budget. Output is illustrative, not validated.
+
+Status: milestone 1, porting the simulation engine.
+
+Layout:
+
+- `internal/engine/` - the pure simulation engine (no web dependencies)
+- `cmd/spreadlab/` - the server binary (milestone 2)
+- `web/` - Vue 3 + TypeScript frontend (milestone 2+)
