FWD (v1 prototype)

CLI

moon run cli -- <schema.yaml> [output.json]
moon run cli -- validate <schema.yaml>
moon run cli -- presets

• If output.json is omitted, JSON IR is printed to stdout.
• Example input: examples/schema_v1.yaml.

Validation JSON Output (v1.1)

moon run cli -- validate <schema.yaml> --json
moon run cli -- validate <schema.yaml> --format json
moon run cli -- validate <schema.yaml> --baseline <baseline.yaml> --json

• stdout is JSON only (no extra human-readable text).
• Exit code is 0 on success, 1 on failure.
• Expected validation failures are reported as JSON with "ok": false.

Builtin Rule Presets

These preset rule names are reserved and provided by the compiler resolve stage:

• hasAtLeastOneState
• hasAtLeastOneTransition
• allReferencesResolved
• noBreakingChanges
• noBreakingChangesOrMigrationDefined

Notes:

• Preset rules can be referenced in transitions.rules by name.
• A schema-defined rule cannot reuse a builtin name; the resolve stage will fail.
• Schema-defined rules are allowed and live in rules:.

Example

Minimal YAML (v1):

fwdVersion: "1.0"
schemaVersion: "1.0"

states:
  - Draft
  - Released

transitions:
  - name: submit
    from: Draft
    to: Released
    rules:
