# Implementation Status Matrix

This document provides a comprehensive overview of which protocols from `@objectstack/spec` have been implemented in the ObjectStack packages.

<Callout type="info">
**Last Updated**: February 2026

This matrix is generated from actual codebase analysis and represents the current implementation status.
</Callout>

## Status Legend

| Symbol | Status | Description |
|:------:|:-------|:------------|
| ✅ | **Fully Implemented** | Production-ready implementation with all core features |
| ⚠️ | **Partially Implemented** | Basic implementation, missing advanced features |
| 🚧 | **In Progress** | Currently being developed |
| 📋 | **Planned** | Scheduled for future implementation |
| ❌ | **Not Implemented** | Protocol defined but not yet implemented |

---

## Core Infrastructure (ObjectOS)

### Runtime & Kernel

| Protocol | @objectstack/core | @objectstack/runtime | @objectstack/objectql | Status |
|:---------|:-----------------:|:--------------------:|:---------------------:|:------:|
| **Manifest** | ✅ | ✅ | ✅ | ✅ Full |
| **Context** | ✅ | ✅ | ✅ | ✅ Full |
| **Plugin** | ✅ | ✅ | ❌ | ✅ Full |
| **Plugin Lifecycle** | ✅ | ❌ | ❌ | ✅ Full |
| **Plugin Capability** | ✅ | ❌ | ❌ | ✅ Full |
| **Service Registry** | ✅ | ❌ | ❌ | ✅ Full |
| **Startup Orchestrator** | ✅ | ❌ | ❌ | ✅ Full |
| **Events** | ✅ | ❌ | ❌ | ✅ Full |

**Notes:**
- Core package provides complete microkernel implementation
- Plugin system supports lifecycle hooks, dependency resolution, and service injection
- Event bus enables inter-plugin communication
- ObjectQL serves as the **example kernel** — a reference implementation that will be modularized into plugins

### Data Infrastructure

| Protocol | @objectstack/objectql | @objectstack/runtime | @objectstack/driver-memory | Status |
|:---------|:---------------------:|:--------------------:|:--------------------------:|:------:|
| **Driver** | ✅ | ✅ | ⚠️ | ✅ Interface |
| **Datasource** | ✅ | ✅ | ❌ | ✅ Full |
| **Data Engine** | ✅ | ❌ | ❌ | ✅ Full |
| **Query** | ✅ | ⚠️ | ⚠️ | ⚠️ Partial |
| **Filter** | ✅ | ⚠️ | ⚠️ | ⚠️ Partial |

**Notes:**
- ObjectQL implements complete IDataEngine interface
- Memory driver is reference implementation (basic CRUD only)
- Advanced query features (aggregations, window functions) require production drivers
- Memory driver supports aggregations (groupBy, count, sum, avg, min, max)

### Metadata Framework

<Callout type="info">
**Runtime Boundary** — ObjectOS metadata is file/artifact-backed and read-only at boot. Database-backed metadata persistence exists for explicitly configured control-plane services, not as an automatic ObjectOS project-DB bridge.
</Callout>

- Metadata API (list types, list items, get item) is fully functional
- Metadata is loaded from config files or `dist/objectstack.json` at startup and held in memory
- `MetadataPlugin` no longer registers `sys_metadata` / `sys_metadata_history` into ObjectOS or auto-bridges ObjectQL to `DatabaseLoader`
- Future: production Artifact API loader and durable local artifact cache

### System Services

---

## API Layer (Transport)

### HTTP & REST

| Protocol | @objectstack/runtime | @objectstack/plugin-hono-server | @objectstack/client | Status |
|:---------|:--------------------:|:-------------------------------:|:-------------------:|:------:|
| **REST Server** | ✅ | ✅ | ❌ | ✅ Full |

| **OData** | ❌ | 📋 | Protocol defined, not implemented |
| **GraphQL** | ❌ | 📋 | Protocol defined, not implemented |
| **Realtime** | ❌ | 📋 | Protocol defined, not implemented |

---

## UI Layer (ObjectUI)

### View System

| Protocol | @objectstack/spec | Implementation | Status |
|:---------|:-----------------:|:-------------:|:------:|
| **View** | ✅ | 🟡 | 🟡 Studio/ObjectUI renders authored metadata surfaces; general-purpose renderer coverage is still incomplete |
| **ListView** | ✅ | 🟡 | 🟡 ObjectUI grid/list surfaces support per-view persistence, filters, row actions, density, galleries, and permission-aware affordances; full protocol parity is ongoing |
| **FormView** | ✅ | 🟡 | 🟡 ObjectUI forms support live field rules (`visibleWhen` / `readonlyWhen` / `requiredWhen`), inline-grid row rules, and server-aligned required enforcement |
| **Page** | ✅ | 🟡 | 🟡 Record-page authoring, page create flows, block canvas editing, slotted record pages, and selected page blocks are implemented in ObjectUI; full component catalogue remains in progress |
| **App** | ✅ | 🟡 | 🟡 Navigation metadata is consumed by the console/app shell; full renderer parity remains in progress |
| **Dashboard** | ✅ | 🟡 | 🟡 ObjectUI renders metric/chart/list/pivot/funnel/table widgets, drill-downs, type-aware cells, and dataset-bound widgets; Studio can author per-widget dataset bindings (`dataset` / `dimensions` / `values`) |
| **Report** | ✅ | 🟡 | 🟡 ObjectUI renders spec-native tabular/summary/matrix/joined reports, chart/KPI blocks, drill-downs, and dataset-bound reports |
| **Action** | ✅ | 🟡 | 🟡 ObjectUI supports row/global/header actions, action modal transport, parameter collection, visibility CEL, and nested action runners |
| **Component** | ✅ | 🟡 | 🟡 Selected page/record components render in ObjectUI (`record:alert`, related lists, highlights, page blocks); catalogue parity remains in progress |
| **Theme** | ✅ | ❌ | ❌ Spec only |
| **Widget** | ✅ | 🟡 | 🟡 Dashboard/report/list/form widgets render in ObjectUI; custom widget manifest/runtime parity remains in progress |
| **Chart** | ✅ | 🟡 | 🟡 Recharts-backed dashboard/report charts cover bar/line/pie/area/scatter/funnel/gauge/treemap/sankey with formatting and field-coverage guards |

**Notes:**
- All UI protocols are fully defined in spec
- Metadata API can retrieve UI definitions (views, apps, pages, dashboards,
  reports, actions)
- Active Studio/ObjectUI source lives in the sibling `../objectui` repo and is
  bundled into `packages/console` via the objectui refresh workflow
- Metadata-admin curated forms now merge server-only fields back into the save
  payload, so a Studio form that exposes only part of a metadata type should
  not strip newer protocol properties
- The 2026-05-08 → 2026-06-08 ObjectUI scan covered 910 non-merge frontend
  commits. The largest functional clusters were metadata-admin/Studio,
  master-detail forms, reports/dashboards, record detail/related lists,
  action transport, flow designer, developer/API pages, AI draft publishing,
  and i18n.
- React SDK provides data hooks; the cross-surface renderer is still being
  completed in ObjectUI rather than in this backend repo

## Automation Layer

<Callout type="warn">
**Plugin-Provided Service** — The kernel does NOT include an automation engine. Flow, workflow, and approval services must be provided by plugins (e.g., `@objectstack/plugin-automation`).
</Callout>

| Protocol | @objectstack/spec | Kernel | Plugin Required | Status |
|:---------|:-----------------:|:------:|:---------------:|:------:|
| **Flow** | ✅ | ❌ | ✅ | 📋 Plugin |
| **Workflow** | ✅ | ❌ | ✅ | 📋 Plugin |
| **Approval** | ✅ | ❌ | ✅ | 📋 Plugin |
| **Webhook** | ✅ | ❌ | ✅ | 📋 Plugin |
| **ETL** | ✅ | ❌ | ✅ | 📋 Plugin |
| **Sync** | ✅ | ❌ | ✅ | 📋 Plugin |
| **Trigger Registry** | ✅ | ❌ | ✅ | 📋 Plugin |

**Notes:**
- Hook system is implemented in ObjectQL (beforeFind, afterInsert, etc.) — this is data-layer eventing, not workflow automation
- Full workflow/automation engine will be provided by plugins
- Protocols are complete and ready for plugin implementation
- Discovery API reports automation service as `unavailable` until a plugin is registered

---

## Security Layer

<Callout type="warn">
**Plugin-Provided Service** — The kernel does NOT handle authentication or authorization. Security services must be provided by plugins (e.g., `@objectstack/plugin-auth`). The Discovery API reports auth as `unavailable` until a plugin is registered.
</Callout>

### Auth Service (`plugin-auth`)

The `auth` service in `CoreServiceName` covers both **authentication** (identity) and **authorization** (permissions). There is no separate `permission` service — it is part of `auth`.

| Protocol | Area | @objectstack/spec | Kernel | Plugin Required | Status |
|:---------|:-----|:-----------------:|:------:|:---------------:|:------:|
| **Identity** | Authentication | ✅ | ❌ | ✅ | 📋 Plugin |
| **Auth Config** | Authentication | ✅ | ❌ | ✅ | 📋 Plugin |
| **Role** | Authentication | ✅ | ❌ | ✅ | 📋 Plugin |
| **Organization** | Authentication | ✅ | ❌ | ✅ | 📋 Plugin |
| **Policy** | Authentication | ✅ | ❌ | ✅ | 📋 Plugin |
| **SCIM** | Authentication | ✅ | ❌ | ✅ | 📋 Plugin |
| **Permission** | Authorization | ✅ | ✅ Phase-1 | ✅ | ✅ `plugin-security` |
| **Sharing** | Authorization | ✅ | ❌ | ✅ | 📋 Plugin |
| **RLS** | Authorization | ✅ | ✅ Phase-1 (tenant + owner) | ✅ | ✅ `plugin-security` |
| **Territory** | Authorization | ✅ | ❌ | ✅ | 📋 Plugin |

**Notes:**
- All security protocols (identity + permission) are delivered by a single `auth` plugin — matching `CoreServiceName`
- Client SDK supports bearer token header — but token validation requires the auth plugin
- Auth route (`/auth/*`) only appears in Discovery when the auth plugin is registered
- Fine-grained authorization (RLS, sharing, territory) is internal to the auth plugin
- **Phase-1 RBAC enforcement is live end-to-end**: REST → ObjectQL → SecurityPlugin middleware now receives a populated `ExecutionContext` (userId, tenantId, roles, permissions). Default `member_default` permission set ships a wildcard RLS rule `organization_id = current_user.organization_id` plus per-object overrides `sys_organization_self` (`id = current_user.organization_id`) and `sys_user_self` (`id = current_user.id`) for the global tables that lack an `organization_id` column. The earlier `tenantField` indirection (RLS expressions written against an abstract `tenant_id` column then rewritten to the configured physical column at compile time) was removed — the placeholder, the column name, and `RLSUserContext.organization_id` are now the same name end-to-end. The legacy `objectql.registerTenantMiddleware` (hardcoded `where.tenant_id` injection that pre-dated SecurityPlugin) has been removed; SecurityPlugin is the sole authority for tenant isolation. Analytics now uses the same reusable read scope via `security.getReadFilter`, so dataset-bound dashboards/reports do not bypass RLS. Verified cross-organization isolation on `pnpm dev:crm` across `sys_organization`, `sys_member`, `sys_user`, `sys_user_permission_set`, `sys_role_permission_set`. **Anonymous traffic still bypasses enforcement** until a default-deny pass lands.

- [x] Authentication Plugin (`@objectstack/plugin-auth`, better-auth)
- [x] Authorization Plugin — `@objectstack/plugin-security` enforces CRUD/FLS/RLS in the ObjectQL middleware chain; REST → ObjectQL now propagates `ExecutionContext` end-to-end (Phase-1)
- [x] Row-Level Security — default `member_default` permission set applies a wildcard `organization_id = current_user.organization_id` rule plus per-object overrides `sys_organization_self` / `sys_user_self`. The earlier `tenantField` rewrite indirection was removed: RLS column, placeholder, and `RLSUserContext.organization_id` use the same canonical name end-to-end
- [x] Analytics RLS bridge — `@objectstack/service-analytics` auto-bridges to `security.getReadFilter(object, context)` and fails closed when read-scope resolution cannot be safely applied
- [x] Multi-tenancy — verified cross-organization isolation on `pnpm dev:crm` (Alice@OrgAlpha vs. Bob@OrgBeta only see their own records across `sys_organization`, `sys_member`, `sys_user`, and `sys_*_permission_set` link tables)
- [x] Legacy `objectql.registerTenantMiddleware` removed — SecurityPlugin is now the sole tenant-isolation authority
- [ ] Default-deny for anonymous traffic
