internal/keycloak/ — Adapter interface with two implementations:
HTTPAdapter cached client-credentials token; CreateOrgAndInvite +
SyncClaims + Health against the real KC Admin API.
Mock in-process map for unit tests + dev convenience when
KEYCLOAK_ADMIN_URL is empty. Used by the eachStore harness.
POST /v1/tenants now accepts admin_email + admin_name. When set, the
adapter creates a KC organization, invites the user as IT_ADMIN, and
triggers VERIFY_EMAIL + UPDATE_PASSWORD. Response wraps the tenant
with TenantCreated{tenant, invite_url}. KC failures DO NOT roll the
tenant back — they emit a keycloak.provision_failed audit event.
Successful invites emit keycloak.invite_sent.
POST /v1/internal/keycloak/claims resolves a tenant's current claim
bundle (tenant_id, slug, products, plan, status). Lookup chain:
body.tenant_id → body.tenant_slug → user_attrs.tenant_id →
user_attrs.tenant_slug.
Config: KEYCLOAK_ADMIN_URL / REALM / CLIENT_ID / CLIENT_SECRET;
empty URL falls back to Mock.
Tests:
internal/keycloak/mock_test.go conflict surfacing, FailNext hook,
SyncClaims persistence.
internal/keycloak/client_test.go HTTPAdapter against an in-process
stub KC: health, full create-org-
and-invite, conflict, token-cache,
401 retry, ErrUnavailable.
internal/server/keycloak_test.go eachStore integration: provisions
via mock; failure path emits
provision_failed audit; claims
endpoint via every lookup variant
+ 404 + 400.
OpenAPI extended with TenantCreated + Claims schemas and the new
claims endpoint. Contract test asserts the new path.
CI: include internal/keycloak/... in the test package list so
HTTPAdapter coverage counts. Total project line coverage: 71.6%.

// Package keycloak adapts the Keycloak Admin API to the tenant-registry's
|
|
// language of "tenants" and "IT_ADMIN invites".
|
|
//
|
|
// The Adapter interface is the seam: tenant-registry handlers depend on
|
|
// it, never on the concrete HTTP client. Tests use Mock; production uses
|
|
// HTTPAdapter against the real KC at the configured base URL.

|
//
|
|
// Required Keycloak features (verified against KC 26):
|
|
// - Organizations feature enabled in the realm (organizationsEnabled: true)
|
|
// - Realm roles: BREAKPILOT_ADMIN, SUPPORT_ENGINEER, SALES_REP
|
|
// - Group `/IT_ADMIN` (used as the org_role marker for invited users)
|
|
//
|
|
// All errors are wrapped with %w so callers can errors.Is them against
|
|
// ErrUnauthorized / ErrOrgConflict / ErrUserConflict.
