Configuration model

Dhal is config-first. Most behavior is controlled through dhal.json.

Top-level structure:

{
  "mode": "monitor",
  "trustProxy": false,
  "runtime": {},
  "identity": {},
  "ip": {},
  "rateLimit": {},
  "rules": {},
  "routes": {},
  "policy": {},
  "observability": {},
  "response": {}
}

Load and validate

npx dhal test-config
npx dhal schema dhal.schema.json

Migrate

npx dhal migrate dhal.json dhal.migrated.json

Explain

npx dhal explain-config

Use presets

npx dhal presets apply starter --output dhal.starter.json

Presets are overlays. They do not hide behavior: inspect the generated config before applying it.
