+# NODEDC MISSION CORE monorepo
+
+This document maps the renamed repository to the target Mission Core
+architecture without claiming that unfinished package boundaries already
+exist.
+
+## Current layout
+
+| Path | Current responsibility | Target responsibility |
+| --- | --- | --- |
+| `apps/control-station/` | React shell, device workflow, spatial scene | Vendor-neutral operator application |
+| `src/k1link/web/` | Local FastAPI control plane and K1 session orchestration | Generic host APIs plus plugin supervisor |
+| `src/k1link/viewer/` | Replay runtime and Rerun adapter | Canonical scene sink and presentation adapter |
+| `src/k1link/ble/` | K1 BLE discovery and reviewed provisioning | `plugins/xgrids-k1` |
+| `src/k1link/mqtt/` | Raw-first K1 MQTT capture | `plugins/xgrids-k1` behind EvidenceStore |
+| `src/k1link/protocol/` | Firmware-scoped K1 codecs | `plugins/xgrids-k1` |
+| `packages/plugin-sdk/` | Contract placeholder | Versioned manifests, capabilities, lifecycle, schemas |
+| `plugins/xgrids-k1/` | Extraction boundary and documentation | Independently versioned device plugin |
+
+## Extraction order
+
+1. Define canonical PointCloud, Pose, DeviceStatus, RawEnvelope, and metrics
+   contracts in the Plugin SDK.
+2. Make Rerun consume canonical frames rather than K1 MQTT topics.
+3. Extract codecs and replay parity fixtures.
+4. Extract raw capture with fault isolation between evidence and preview.
+5. Extract BLE/Wi-Fi provisioning and MQTT into a least-privilege edge worker.
+6. Replace K1-specific host routes and state with plugin/device-session APIs.
+7. Drive the connection wizard from plugin capabilities and schemas.
+8. Re-run native replay and the physical BLE → Wi-Fi → MQTT → scene acceptance.
+
+## Invariants
+
+- Raw evidence is durable before preview work.
+- Mission Core starts when the XGRIDS plugin is absent or disabled.
+- The plugin cannot add global navigation or arbitrary CSS.
+- Vendor writes and commands require declared capabilities and operator gates.
+- The visualization engine can be replaced without changing device plugins.
+- Real captures and credentials remain outside Git.
