Data Flow

DataContext

Shared state container passed through DAG:

type DataContext interface {
    Get(key string) (interface{}, error)
    Set(key string, value interface{}) error
    Has(key string) bool
    Keys() []string
}

Standard Keys

Key	Producer	Consumer	Type
targets	Target Ingestion	Discovery	[]Target
discovered_hosts	Discovery	Port Scanner	[]Host
open_ports	Port Scanner	Banner Grab	[]Port
banners	Banner Grab	Fingerprint	[]Banner
service_fingerprints	Fingerprint	Asset Profiler	[]Fingerprint
asset_profiles	Asset Profiler	Vuln Evaluator	[]AssetProfile
vulnerabilities	Vuln Evaluator	Reporter	[]Vulnerability

Example Flow

Discovery → Set("discovered_hosts", hosts)
   ↓
Port Scanner → Get("discovered_hosts") → Scan → Set("open_ports", ports)
   ↓
Fingerprint → Get("open_ports") → Probe → Set("fingerprints", results)
