A call without a session carries a Hanzo IAM access token: signed by a key in
hanzo.id's JWKS, issued by hanzo.id, minted for this app (aud = IAM_CLIENT_ID)
and unexpired. One resolver, getBearer, sits behind /v1/rpc, /v1/rest and the
download routes, and acts in the team X-Team-Id names: a person as the account
their sign-in linked, an application of IAM_ORG as the team's organisation
owner. API tokens no longer get into the API; Zapier, which could carry nothing
else, is deleted.
Outbound, one Machine mints eSign's client_credentials token for the service it
is spent at. notify uses it as before, and every webhook now carries one minted
for its endpoint's origin, so a Hanzo receiver verifies the caller against
hanzo.id instead of holding a shared secret.
