Trust Levels

The trust ladder is ordered:

Trust	Meaning
`detected`	Signals indicate an agent, but no identity proof exists.
`declared`	The agent identified itself.
`verified`	A token or proof was verified.
`linked`	The verified agent is linked to a known user account.

const identity = await client.authenticate({
  sessionLinkToken: 'ses_...',
  linkedUserId: 'user_123',
})

When multiple auth methods produce identities, the SDK keeps the highest-trust result.
