Functions ¶

func Verify ¶

func Verify(doc Document) (int, error)

Verify checks the document format, policy digest, event hash chain, and every event signature. It returns the number of verified events.

func Write ¶

func Write(w io.Writer, doc Document) error

Write serializes a document as stable, human-inspectable JSON.

Types ¶

type Document ¶

type Document struct {
	Format          string         `json:"format"`
	GeneratedAt     time.Time      `json:"generated_at"`
	RunewardVersion string         `json:"runeward_version"`
	Policy          PolicySnapshot `json:"policy"`
	Chronicle       ledger.Bundle  `json:"chronicle"`
}

Document combines policy context with the signed Chronicle audit bundle. The embedded ledger public key verifies event integrity; organizations can pin that key out-of-band when they need identity assurance as well.

func New ¶

func New(version, name, source, image, resolved string, findings []Finding, bundle ledger.Bundle) Document

New creates an evidence document and hashes the resolved policy snapshot.

func Read ¶

func Read(r io.Reader) (Document, error)

Read decodes an evidence document.

type Finding ¶

type Finding struct {
	Severity string `json:"severity"`
	Field    string `json:"field"`
	Message  string `json:"message"`
}

Finding is a portable policy-lint finding captured at export time.

type PolicySnapshot ¶

type PolicySnapshot struct {
	Name     string    `json:"name"`
	Source   string    `json:"source,omitempty"`
	Image    string    `json:"image,omitempty"`
	Resolved string    `json:"resolved"`
	SHA256   string    `json:"sha256"`
	Findings []Finding `json:"findings,omitempty"`
}

PolicySnapshot records the resolved, secret-redacted policy that governed a run. SHA256 makes accidental or malicious edits independently detectable.
