Add signed registration/enrollment handoffs, per-request assurance
policy with login-session isolation, and /logout. coulomb-social
stays AAL1 unless acr_values or another client raises the bar.
Allow coulomb-social ordinary login at AAL1 via mfaRequired: false while
keeping provider requireForAll for clients without an override. Preserve
explicit acr_values=aal2 for step-up.
Verified first: grant_types_supported advertises client_credentials in
discovery.go, but token.go only ever accepted authorization_code -- no
service-token issuance path exists at all. Building one from scratch is
materially bigger than extending the existing flow; explicitly not
attempted here, left open in the workplan rather than declared done.
What shipped for the human Authorization Code + PKCE flow:
- domain.User.Tenant (new, omitempty) + token.go's effectiveTenant():
falls back to tenant:coulomb (this workstation's actual tenant, ADR-0006)
when unset -- never an empty tenant claim, never a silent reassignment.
- principal_type: "human", unconditional.
- groups/roles promoted from scope-gated to unconditional core claims,
always [] not null when empty. One pre-existing test asserted the old
scope-gated groups behavior -- updated to match the new intentional
behavior, not left failing or reverted.
- assurance built from PKCESession.MFAVerified (new field, threaded
through completeAuthorization's two call sites in authorize.go) --
whether MFA was actually verified in this session, not static enrollment
state. aal2 only when required-and-passed this time, aal1 otherwise.
go build/vet clean, go test ./... green repo-wide. Two new authorize_test.go
cases assert MFAVerified on both paths. tests/profile/profile_test.go's
TestCompleteTokenFlow (the repo's own full HTTP integration test) extended
with real value assertions for all five claims, not just presence checks.
Python conformance tool not run against a live instance (needs the full
Authelia+LLDAP+privacyIDEA stack); TestCompleteTokenFlow's real HTTP round
trip covers the equivalent claim checks instead.
