+# ADR 0003: device plugin UI and runtime boundary
+
+- Status: accepted
+- Date: 2026-07-16
+
+## Context
+
+The verified XGRIDS K1 workflow originally lived directly in the Mission Core
+React shell and local FastAPI service. That preserved experimental speed, but it
+made BLE, Wi-Fi, K1 state fields, and stream actions look like platform concepts.
+Adding a second device that way would spread vendor branches through navigation,
+runtime state, and visualization.
+
+## Decision
+
+Mission Core uses an allowlisted device-plugin registry. Each installed plugin
+provides a versioned manifest, exactly one device model in v1alpha1, a runtime
+provider, and UI contributions for declared host slots. The one-model limit
+matches the current one-runtime-adapter lifecycle; multi-model plugins require
+explicit device-session and model routing in the next SDK version.
+
+The only import of a concrete device plugin from platform code is the composition
+root `apps/control-station/src/composition/devicePlugins.ts`. Shipping another
+frontend plugin therefore requires one reviewed composition-root import; `App`,
+navigation, workspaces, and generic runtime code do not change. Runtime discovery
+of arbitrary JavaScript is deliberately not supported.
+
+Backend factories are loaded only from validated, repository-local manifests.
+Startup fails unless every catalog manifest produces exactly one adapter with
+the same plugin ID and action set. The catalog is then frozen for the life of
+the process, so a backend-catalog model cannot appear without an executable
+runtime. Frontend availability remains the separate reviewed static-composition
+step described below.
+
+The local-device UX is:
+
+```text
+no model selected
+  -> model catalog from registered manifests
+  -> operator selects a model
+  -> host mounts that plugin's device.connection contribution
+  -> plugin performs its own setup and stream workflow
+  -> plugin normalizes status, source, and metrics into MissionRuntimeState
+```
+
+Provider shells remain structurally mounted to keep the Mission Core React tree
+stable, but their contract requires them to be inert while `activeModel` is
+`null`. Before a model is selected, no device API is polled and no discovery,
+credentials, stream controls, or metrics are shown. The selected custom view is
+mounted only for its manifest `componentKey`.
+
+Changing the model is an asynchronous lifecycle transition. The active plugin
+must confirm deactivation; the XGRIDS implementation always issues `stream.stop`
+before its UI is removed. A failed or still-running teardown prevents the switch.
+
+The shared runtime envelope contains only:
+
+- generic lifecycle phase and message;
+- active device identity and an opaque endpoint label;
+- selected spatial source;
+- generic stream mode and metrics;
+- viewer settings.
+
+Vendor fields such as `k1_ip`, `likely_k1`, BLE candidates, MQTT topics, and
+firmware-specific phases remain inside the XGRIDS plugin adapter.
+
+## Current implementation
+
+- Canonical manifest: `plugins/xgrids-k1/plugin.manifest.json`.
+- Host contracts and registry: `apps/control-station/src/core/device-plugins/`.
+- Generic runtime envelope: `apps/control-station/src/core/runtime/`.
+- XGRIDS UI/runtime adapter: `apps/control-station/src/device-plugins/xgrids-k1/`.
+- Read-only backend catalog: `GET /api/v1/device-plugins` and
+  `GET /api/v1/device-models`.
+- Host-owned action dispatcher:
+  `POST /api/v1/device-plugins/{pluginId}/actions/{actionId}`.
+- Plugin-scoped event stream:
+  `WS /api/v1/device-plugins/{pluginId}/events`, with plugin ID and sequence.
+- Manifest factory composition:
+  `src/k1link/web/device_plugin_composition.py`.
+- Existing K1 action endpoints are compatibility shims over that dispatcher, so
+  the proven physical implementation is unchanged.
+
+The XGRIDS frontend code is statically linked into the Control Station during
+this v1alpha milestone. It is isolated by imports and contracts but is not yet a
+separately built npm workspace package. Backend composition is manifest-driven;
+frontend/backend installed-set parity is a reviewed build-time responsibility
+until the host gains signed plugin bundles and a startup compatibility handshake.
+
+## Required dependency rules
+
+- Core cannot import a concrete plugin outside the composition root.
+- Core cannot inspect opaque plugin state or branch on a model ID.
+- Plugins render only inside declared slots and cannot own global navigation or
+  global CSS.
+- Plugins publish canonical spatial sources; they do not control the scene
+  engine or route names.
+- Passwords and other secrets cannot enter manifests, runtime snapshots, event
+  payloads, or browser persistence.
+- Invalid or duplicate plugin/model IDs fail registry construction.
+- Manifest/runtime ID or action drift fails backend startup.
+- Every v1alpha1 plugin declares exactly one model and a non-mutating,
+  secret-free `state.read` action.
+- A plugin must stop or cancel active work before model selection can change.
+
+Manifest `permissions`, action `mutating`, and `secretFields` are validated and
+exposed as declarative contract metadata in v1alpha1. They do not yet implement
+operator authorization, policy enforcement, or secret-vault substitution; the
+dispatcher enforces only installed plugin IDs and declared action IDs. Until the
+next SDK milestone, plugin adapters remain responsible for request validation
+and for keeping secret values out of state, events, logs, and browser storage.
+
+## Lifecycle model
+
+Enrollment, connectivity, and streaming are the target independent state
+machines. The v1alpha shared runtime currently exposes an aggregate `phase`
+plus `sourceMode`; plugins must keep their detailed state private until the
+three fields are added to the stable SDK:
+
+```text
+Enrollment:   empty -> selecting_model -> setup_in_progress -> enrolled
+Connectivity: unknown/offline -> connecting -> connected -> degraded/offline
+Stream:       idle -> starting -> streaming -> stopping -> idle
+                                \-> failed -> idle
+```
+
+The current XGRIDS contribution maps its proven internal workflow into those
+platform states without changing the wire protocol:
+
+```text
+confirm power -> scan BLE -> select candidate -> enter Wi-Fi
+-> provision once -> receive LAN address -> start source
+-> wait for first point frame -> streaming
+```
+
+## Consequences and next extraction
+
+The shell can now boot with no selected device and contains no K1 wire fields.
+Adding another statically reviewed UI plugin does not require changing `App` or
+the generic local-device workspace.
+
+Backend execution supports only reviewed `transitional-in-process` plugins in
+v1alpha1, but already enters through the manifest
+factory, allowlisted XGRIDS facade and host-owned dispatcher. Synchronous
+capture/runtime work is moved off the API event loop. The next milestone adds
+independent device-session IDs, operation IDs, cancellation, timeouts, audited
+secret references, and process isolation. Only after replay parity and a
+physical regression may BLE, MQTT, codecs, and raw evidence code move out of
+the compatibility package. Rerun must ultimately consume canonical
+PointCloud/Pose envelopes instead of K1 topics.
+
+This ADR supersedes the compatibility names listed in ADR 0002: `K1Metrics`,
+`useK1Console`, and `ConsoleService` were renamed and isolated inside the
+XGRIDS adapter without changing the proven transport algorithms.

 Until extraction is complete, `src/k1link` is the compatibility source of
 truth and every move into this package must preserve replay and real-device
 acceptance.
+
+Mission Core imports this plugin only from
+`apps/control-station/src/composition/devicePlugins.ts`. The generic shell never
+branches on this plugin ID or reads `k1_ip`, BLE candidates, MQTT topics, or
+other vendor state.
+
+Backend startup loads the reviewed factory declared by `backendEntrypoint`, then
+cross-checks its plugin ID and complete action set against this manifest.
+Actions enter through the host dispatcher and the transitional facade
+`src/k1link/web/xgrids_k1_facade.py`. The old flat routes live in the plugin's
+legacy router; both paths delegate to the same proven
+`XgridsK1CompatibilityService` methods. Synchronous capture/runtime operations
+run outside the FastAPI event loop.
+
+Model switching calls the plugin deactivation hook and must receive a successful
+`stream.stop` before Mission Core removes this custom UI. BLE, MQTT, codec and
+evidence modules remain in `src/k1link` until replay parity and another physical
+K1 regression are complete.
