internal/keycloak/ — Adapter interface with two implementations:
HTTPAdapter pgxpool-style real Admin API client with cached client-
credentials token (auto-refresh, 401 retry).
Mock in-process map for unit tests + dev convenience when
KEYCLOAK_ADMIN_URL is empty. Used by the eachStore harness.
Adapter contract (adapter.go):
CreateOrgAndInvite(ctx, InviteInput) (*InviteResult, error)
Creates a KC organization, an IT_ADMIN user, adds the user as a
member, triggers VERIFY_EMAIL + UPDATE_PASSWORD execute-actions
email. Atomic from the caller's PoV; partial failures surface as
typed errors (ErrOrgConflict, ErrUserConflict, ErrUnauthorized,
ErrUnavailable).
SyncClaims(ctx, userID, Claims) error
Pushes tenant_id / tenant_slug / org_roles / products / plan /
tenant_status into the user's KC attributes — the same shape the
realm's protocol mappers project into JWTs.
Health(ctx) error
Pings /admin/serverinfo; wired into readyz.
Wiring:
POST /v1/tenants now accepts admin_email + admin_name. When set, the
adapter creates the org and invites the user. Response wraps the
tenant with the new TenantCreated{tenant, invite_url} shape so dev
testers can use the action-token URL without waiting for the email.
KC failures DO NOT roll the tenant back — they emit a
keycloak.provision_failed audit event so the operator can resend.
Successful invites emit keycloak.invite_sent.
POST /v1/internal/keycloak/claims resolves a tenant's current claim
bundle. Lookup chain: body.tenant_id → body.tenant_slug →
body.user_attrs.tenant_id → body.user_attrs.tenant_slug. The realm's
protocol mapper calls this at token issuance, or operators on demand.
Config: KEYCLOAK_ADMIN_URL / REALM / CLIENT_ID / CLIENT_SECRET; empty
URL falls back to Mock for dev.
OpenAPI: TenantCreated + Claims schemas added; /v1/internal/keycloak/claims
documented. Contract test extended to cover the new endpoint.
Tests:
internal/keycloak/mock_test.go Mock semantics: conflict surfacing,
FailNext hook, SyncClaims persistence.
internal/server/keycloak_test.go KC provisioning end-to-end via
eachStore: invite_url returned,
mock records, invite_sent audit;
failure path emits provision_failed
but tenant still lands; claims
endpoint resolves via tenant_id /
tenant_slug / user_attrs / 404 / 400.
The real-KC integration test (against a testcontainers-spun KC 26)
lands in a follow-up — gating it behind KEYCLOAK_INTEGRATION=1 + a
slower nightly CI is cleaner than baking 30s+ of KC boot into every PR.
Refs: M4.3
Full M4.2 deliverable: 16 endpoints (tenants CRUD + lifecycle, catalog, entitlements, API keys with argon2 hashing, audit append + filter), Store interface with pgx-backed Postgres + in-memory parallel implementations exercised by the same eachStore harness, openapi.yaml at 3.1 with kin-openapi contract test. M4.3 adds auth.
Refs: M4.2
Minimal Go service: /healthz + /v1/tenants/by-slug/:slug + /v1/tenants/:id with an in-memory store seeded with the acme tenant. Stdlib-only; pgx + JWT validation land in M4.1 follow-up.
