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.
Add an opt-in human approval gate so Agent runs pause before executing
MCP tools that operators flag as dangerous, surface an approval card in
the chat UI, and only resume after the user approves (optionally with
edited args) or rejects.
Backend
- New mcp_tool_approvals table + repo/service to mark per-tool approval
required (PG migration 000042 + sqlite init).
- approval.Gate coordinates RequestAndWait / Resolve with sync.Once
delivery, configurable timeout, and Redis Pub/Sub fan-out so multi-
replica deployments work without sticky sessions.
- MCPTool.Execute integrates the gate; uses a round-level ApprovalCtx
(without the per-tool 60s timeout) for the wait, and re-derives a
fresh 60s exec ctx after approval so CallTool keeps a full window.
- New SSE response types (tool_approval_required / _resolved) and
EventBus events plumb approval state to AgentStreamDisplay.
- REST: list/set per-tool approval flag, resolve pending approval.
- Configurable via agent.tool_approval_timeout_seconds (yaml) or
WEKNORA_AGENT_TOOL_APPROVAL_TIMEOUT env (accepts seconds or Go
duration).
Frontend
- MCP settings: per-tool "require approval" switch on the test panel.
- Chat: ToolApprovalCard renders the pause point with editable JSON
args, validation feedback, mm:ss countdown that turns warning/danger
near deadline, and a resolved state that retains context.
- i18n strings added for zh-CN / en-US / ko-KR / ru-RU.
Docs
- docs/zh/mcp-approval.md covering behavior, config, API, deployment
considerations (Redis cross-instance, restart limitations).
- Added a new `.env.lite.example` file for the Lite version, providing a minimal configuration template.
- Updated `.env.example` to remove deprecated variables and include new Docreader settings.
- Enhanced Docker configurations to support the Lite version, including a new Dockerfile for the Docreader service.
- Introduced a Makefile target for building and running the Lite version, along with packaging capabilities.
- Created GitHub workflows for building and releasing Lite binaries, including Homebrew formula support.
- Implemented a new service file for managing the Lite version as a system service.
This update enables a streamlined, single-binary deployment of WeKnora, reducing external dependencies and simplifying setup.
