Tighten correctness, security and observability of the tenant RBAC
foundation introduced in 3c4cdd70 in response to internal review.
Bugfixes
- custom_agents.runnable_by_viewer: drop the GORM `default:true` tag.
GORM treats a plain bool's zero value as "unspecified" and silently
rewrites it to the column default on insert, which would prevent
admins from ever creating an agent with viewer-runtime disabled. The
column-level DEFAULT TRUE on the database side still backstops rows
inserted by raw SQL / migrations.
- TenantMemberRepository.HasAnyMembers: replace `Limit(1).Count(&n)`
with `Take(&probe)`. GORM's Count ignores Limit and scans the whole
table, which matters because this runs on the auth middleware's
hot path for users without a cached membership.
- service/user.LoginWithOIDC: include User, Tenant and Memberships in
the OIDCCallbackResponse so the OIDC flow returns the same shape as
password login (previously User and friends were left nil).
Security
- middleware/auth.resolveTenantRole: restrict orphan-tenant
auto-promotion to the caller's home tenant. Cross-tenant superuser
visits and JWTs minted for foreign tenants no longer trigger silent
Owner grants. Two regression tests pin the new behaviour.
- service/user.synthFallbackMembership: default the synthesised role
to Viewer instead of Owner. The login response only feeds UI; the
backend re-derives the real role from tenant_members on every
request, so showing a Viewer UI is preferable to a misleading Owner
UI that would surface admin controls the backend will then 403.
- migrations/versioned/000043_tenant_rbac.down.sql: gate the destructive
drop behind a `weknora.allow_destructive_migration` GUC so an
accidental `migrate down` cannot wipe role data in production.
- frontend/src/stores/auth.ts: comment currentTenantRole as
rendering-only so future PRs cannot mistake the localStorage-backed
value for an authorisation signal.
API contract
- Memberships in LoginResponse and OIDCCallbackResponse now serialises
without omitempty, and buildMembershipsForUser / synthFallbackMembership
always return a non-nil slice — frontend can rely on JSON `[]`.
- handler/auth.GetCurrentUser includes memberships so /auth/me refreshes
recover currentTenantRole after a page reload.
Performance
- Add TenantService.GetTenantsByIDs (with the matching repo method) and
use it inside buildMembershipsForUser to batch tenant-name lookups
instead of issuing one query per membership.
Observability
- Replace the remaining `log.Printf` calls in middleware/auth with
contextual logger.Warnf / logger.Infof so role resolution events ride
the standard request-id / Langfuse trace plumbing. The successful
auto-promote line is tagged `[audit]` for log mining.
Tests
- internal/application/service/tenant_member_test.go: hand-rolled
fakeTenantMemberRepo plus 11 cases covering AddMember validation,
EnsureOwner idempotence, "cannot demote/remove the last Owner",
same-role no-op, ErrInvalidTenantRole / ErrMembershipNotFound, and
the TenantRole.HasPermission lattice.
- internal/middleware/auth_role_test.go: fakeMemberService plus 8 cases
pinning every branch of resolveTenantRole, including the two H1
regressions (cross-tenant superuser must not auto-promote; orphan
auto-promote requires the home tenant).
Lay the foundation for tenant-level RBAC without enforcing it yet.
Schema, types, middleware lookup, and login-flow shape changes ship now;
RequireRole/route annotations and member-management endpoints follow in
PR 2 and PR 3.
Highlights:
- New tenant_members table (Postgres + SQLite) with (user_id, tenant_id)
unique key and (owner|admin|contributor|viewer) role values. Migration
000043 backfills one row per existing user, marking the earliest-created
active user in each tenant as Owner and the rest as Contributor.
- KnowledgeBase.creator_id and CustomAgent.runnable_by_viewer added so
PR 2 can wire ownership-based and Viewer-runtime checks.
- Auth middleware loads the active TenantMember row, sets a new
TenantRoleContextKey, and falls back via three escape hatches:
cross-tenant superusers (CanAccessAllTenants) get Admin in the target
tenant; orphan tenants (zero members) auto-promote the first authenticating
human to Owner; and when tenant.enable_rbac is false (the v1 default)
unmatched lookups fail open with Admin to preserve current behaviour.
- Register / OIDC provisioning now insert an Owner membership for the
registrant via TenantMemberService.EnsureOwner.
- LoginResponse renamed tenant -> active_tenant and gained a memberships
array. POST /auth/switch-tenant issues a fresh token pair scoped to a
target membership; GET /auth/config exposes auth.registration_mode for
the frontend register-tab gating.
- New config keys: auth.registration_mode (self_serve | invite_only,
defaults to self_serve) and tenant.enable_rbac (defaults to false).
Both have WEKNORA_* env overrides.
- Frontend store persists memberships and exposes currentTenantRole;
Login.vue calls /auth/config and hides the Register tab in invite_only
mode. Go SDK types updated to match the new LoginResponse shape.
- Added support for tracking the status of FAQ import tasks, including progress indicators for ongoing imports.
- Introduced new localization strings for processing tasks and batch operations in multiple languages.
- Updated the FAQ entry manager to display import progress and improved user feedback during the import process.
- Enhanced the KnowledgeBase component to reflect the processing state of knowledge items, improving user experience during document uploads.
- Implemented batch deletion functionality for chunks, streamlining the management of knowledge base content.
