Functions ¶

func NormalizeRepository ¶

func NormalizeRepository(repo string) (string, bool)

NormalizeRepository returns a canonical lowercase owner/name repository.

Types ¶

type Claims ¶

type Claims struct {
	Version    int      `json:"v"`
	Audience   string   `json:"aud"`
	Run        string   `json:"run"`
	Invocation string   `json:"inv"`
	Repo       string   `json:"repo"`
	Profile    string   `json:"profile"`
	Operations []string `json:"ops"`
	NotBefore  int64    `json:"nbf"`
	Expires    int64    `json:"exp"`
}

Claims is the invocation-bound capability payload minted by AWF.

func (*Claims) AgentID ¶

func (c *Claims) AgentID() string

AgentID returns the stable DIFC registry key for this invocation.

func (*Claims) AllowsOperation ¶

func (c *Claims) AllowsOperation(operation string) bool

AllowsOperation reports whether the invocation capability permits operation.

type Policy ¶

type Policy struct {
	Version                 int                `json:"version"`
	Profile                 string             `json:"profile"`
	Audience                string             `json:"audience"`
	WorkflowRunID           string             `json:"workflow_run_id"`
	Repositories            []RepositoryPolicy `json:"repositories"`
	PublicMinIntegrity      string             `json:"public_min_integrity"`
	AllowedOperations       []string           `json:"allowed_operations"`
	MaxCapabilityTTLSeconds int64              `json:"max_capability_ttl_seconds"`
}

Policy is the compiler-owned authorization contract for one workflow run.

func ParsePolicy ¶

func ParsePolicy(raw string) (*Policy, error)

ParsePolicy parses and validates a compiler-generated enclave policy.

func (*Policy) AllowsOperation ¶

func (p *Policy) AllowsOperation(operation string) bool

AllowsOperation reports whether operation is enabled by the compiler policy.

func (*Policy) GuardPolicyJSON ¶

func (p *Policy) GuardPolicyJSON() (string, error)

GuardPolicyJSON returns the internal allow-only policy for this enclave profile.

func (*Policy) GuardRepos ¶

func (p *Policy) GuardRepos() []string

GuardRepos returns exact assigned repositories followed by the public catch-all.

func (*Policy) HasRepository ¶

func (p *Policy) HasRepository(repo string) bool

HasRepository reports whether repo is an assignable repository in the policy.

func (*Policy) RepositorySensitivity ¶

func (p *Policy) RepositorySensitivity(repo string) (string, bool)

RepositorySensitivity returns the configured sensitivity for repo.

func (*Policy) Validate ¶

func (p *Policy) Validate() error

Validate checks policy invariants and canonicalizes set-like fields.

type RepositoryPolicy ¶

type RepositoryPolicy struct {
	Repo        string `json:"repo"`
	Sensitivity string `json:"sensitivity"`
}

RepositoryPolicy identifies a repository assignable to an enclave invocation.

type Route ¶

type Route struct {
	Operation string
	Owner     string
	Repo      string
	Number    string
}

Route is a validated issues-read-v1 REST request.

func MatchRoute ¶

func MatchRoute(path string, query url.Values) (*Route, error)

MatchRoute matches only the versioned enclave issue-read REST surface.

func (*Route) FullRepo ¶

func (r *Route) FullRepo() string

FullRepo returns the canonical lowercase owner/name target.

type Verifier ¶

type Verifier struct {
	// contains filtered or unexported fields
}

Verifier verifies HMAC-signed invocation capabilities against one workflow policy.

func NewVerifier ¶

func NewVerifier(rootKeyHex string, policy *Policy) (*Verifier, error)

NewVerifier creates a capability verifier from a 32-byte lowercase-hex root key.

func (*Verifier) VerifyAuthorization ¶

func (v *Verifier) VerifyAuthorization(header string) (*Claims, error)

VerifyAuthorization verifies a Bearer capability at the current time.
