Overview ¶

Package identity defines Harbor's load-bearing isolation key.

Every Runtime, Protocol, Memory, State, Skills, Tools, Planner and Governance code path scopes its work by the (TenantID, UserID, SessionID) triple. The triple is the isolation boundary; RunID is the per-execution scope inside a session and is carried by Quadruple — never substituted for Identity in scoping decisions.

Identity is mandatory: there is no opt-out knob (decisions.md D-001). Validate fails closed when any component is empty; With and WithRun validate at write time so bugs surface at the call site.

This package is dependency-free and holds no package-level mutable state beyond two unexported context-key sentinels. Concurrent reuse is safe by construction (decisions.md D-025).

Functions ¶

func Validate ¶

func Validate(id Identity) error

Validate returns an error wrapping ErrIdentityIncomplete when any of (TenantID, UserID, SessionID) is empty. Whitespace-only strings pass; the caller is responsible for input normalization.

func With ¶

func With(ctx context.Context, id Identity) (context.Context, error)

With attaches Identity to ctx. Returns the original ctx and a wrapped ErrIdentityIncomplete if the Identity fails Validate.

func WithRun ¶

func WithRun(ctx context.Context, id Identity, runID string) (context.Context, error)

WithRun attaches a Quadruple (Identity + RunID) to ctx. The Identity must Validate; the RunID must be non-empty. Returns the original ctx and a wrapped ErrIdentityIncomplete on either failure.

Types ¶

type Identity ¶

type Identity struct {
	TenantID  string
	UserID    string
	SessionID string
}

Identity is the load-bearing isolation key. All three components are mandatory; an Identity with any empty component is rejected by Validate.

func From ¶

func From(ctx context.Context) (Identity, bool)

From returns the Identity in ctx and a presence bool. Use when absence is recoverable (e.g. cross-cutting middleware that may run pre-auth).

func MustFrom ¶

func MustFrom(ctx context.Context) Identity

MustFrom returns the Identity in ctx. Panics with ErrIdentityMissing when none is present. Use in handler/runtime paths where the caller has already established that identity is mandatory at this point.

type Quadruple ¶

type Quadruple struct {
	Identity
	RunID string
}

Quadruple is Identity + the per-execution RunID. Used in Envelopes and run-scoped state. Quadruple is NOT a substitute for Identity in scoping decisions: the triple is the isolation boundary; RunID is the per-execution scope inside a session.

func MustQuadrupleFrom ¶

func MustQuadrupleFrom(ctx context.Context) Quadruple

MustQuadrupleFrom returns the Quadruple in ctx. Panics with ErrIdentityMissing when none is present. The Quadruple key is independent from the Identity key: a context attached via With does NOT satisfy MustQuadrupleFrom, and vice versa.

func QuadrupleFrom ¶

func QuadrupleFrom(ctx context.Context) (Quadruple, bool)

QuadrupleFrom returns the Quadruple in ctx and a presence bool.
