+# ZeroTier Kill Switch
+
+## Overview
+
+The kill-switch mechanism provides emergency deactivation of ZeroTier network access at three granularities: a single device membership, all memberships for a user, or all memberships on a network. All kill operations are **reversible** — they set `active=False` and (in most cases) `status=SUSPENDED` but do not delete records, so affected users can re-activate or re-authenticate.
+
+## Three Kill Operations
+
+| Granularity | Endpoint | Admin-only | Behavior |
+|---|---|---|---|
+| **Device X on network Y** | `POST /orgs/<id>/memberships/<id>/deactivate` | No (owner can self-deactivate) | Sets `active=False`. Status stays APPROVED. |
+| **All devices for a user** | `POST /orgs/<id>/kill-switch` | Yes | Sets `active=False`, `status=SUSPENDED` for every active membership in the org (optionally filtered to specific networks). |
+| **All devices on a network** | `POST /orgs/<id>/networks/<id>/kill-switch` | Yes | Sets `active=False`, `status=SUSPENDED` for every active membership on the network, across all users. |
+
+## Detailed Endpoint Reference
+
+### 1. Kill a Single Membership (Device + Network)
+
+```
+POST /api/v1/organizations/<org_id>/memberships/<membership_id>/deactivate
+```
+
+**Auth:** `@login_required`, `@full_access_required`  
+**Admin override:** Admins can deactivate any membership; non-admins can only deactivate their own.
+
+**Request body:** None
+
+**Response (200):**
+```json
+{
+  "success": true,
+  "data": {
+    "request": {
+      "id": "...",
+      "active": false,
+      "status": "approved",
+      ...
+    }
+  },
+  "message": "Request deactivated successfully"
+}
+```
+
+**Behavior:**
+- Ends the active `ActivationSession` with reason `manual_revoke`
+- De-authorizes the device node in the ZeroTier controller
+- Sets `request.active = False` (status **unchanged** — stays `approved`)
+- Logs `zt.membership.deactivated` audit event
+
+**Re-activation:** The user can re-activate via `POST /memberships/<id>/activate` or `POST /memberships/activate-all`.
+
+---
+
+### 2. Kill All Devices for a User
+
+```
+POST /api/v1/organizations/<org_id>/kill-switch
+```
+
+**Auth:** `@login_required`, `@require_admin`, `@full_access_required`
+
+**Request body:**
+```json
+{
+  "target_user_id": "uuid-of-user-to-kill",
+  "scope": "organization",
+  "network_ids": ["uuid-of-network-1", "uuid-of-network-2"],
+  "reason": "Security incident — force deactivation"
+}
+```
+
+| Field | Type | Required | Default | Description |
+|---|---|---|---|---|
+| `target_user_id` | string (UUID) | yes | — | The user to deactivate |
+| `scope` | string | no | `"organization"` | `"organization"` (all networks) or `"selected_networks"` |
+| `network_ids` | array of UUIDs | no | `null` | Required when scope is `selected_networks` |
+| `reason` | string | no | `null` | Max 500 chars |
+
+**Response (200):**
+```json
+{
+  "success": true,
+  "data": {
+    "affected_count": 3
+  },
+  "message": "Kill switch triggered successfully"
+}
+```
+
+**Behavior:**
+- Queries all active, non-deleted `NetworkAccessRequest` rows for the target user
+- For each: ends session (reason `kill_switch`), de-authorizes in ZT
+- Sets `active = False`, **and** sets `status = SUSPENDED` if currently `APPROVED`
+- Logs `zt.kill_switch.activated` audit event with `affected_count` and `scope`
+
+**Re-activation:** The user's memberships are in `SUSPENDED` state. An admin must explicitly re-approve (change status back to `APPROVED`) before the user can re-activate.
+
+---
+
+### 3. Kill All Devices on a Network
+
+```
+POST /api/v1/organizations/<org_id>/networks/<network_id>/kill-switch
+```
+
+**Auth:** `@login_required`, `@require_admin`, `@full_access_required`
+
+**Request body:**
+```json
+{
+  "reason": "Network compromised — emergency deactivation"
+}
+```
+
+| Field | Type | Required | Default | Description |
+|---|---|---|---|---|
+| `reason` | string | no | `null` | Max 500 chars |
+
+**Response (200):**
+```json
+{
+  "success": true,
+  "data": {
+    "affected_count": 12
+  },
+  "message": "Network kill switch triggered successfully"
+}
+```
+
+**Behavior:**
+- Queries all active, non-deleted `NetworkAccessRequest` rows for the network, **regardless of user**
+- For each: ends session (reason `kill_switch`), de-authorizes in ZT
+- Sets `active = False`, and `status = SUSPENDED` if currently `APPROVED`
+- Logs `zt.network_kill_switch.activated` audit event with `affected_count`
+
+**Re-activation:** Same as user kill switch — each affected membership is `SUSPENDED` and needs admin re-approval.
+
+## Comparison: Deactivation vs. Deletion
+
+| Operation | active | status | deleted_at | DB row | Reversible? |
+|---|---|---|---|---|---|
+| `POST /memberships/<id>/deactivate` | `false` | unchanged | `null` | preserved | Yes — re-activate |
+| `POST /kill-switch` (user) | `false` | `suspended` | `null` | preserved | Yes — admin re-approve |
+| `POST /networks/<id>/kill-switch` | `false` | `suspended` | `null` | preserved | Yes — admin re-approve |
+| `DELETE /memberships/<id>` (soft) | `false` | unchanged | set | preserved | Partial — depends on join logic |
+| `DELETE /admin/memberships/<id>` | `false` | — | — | **hard-deleted** | No |
+
+## Audit Events
+
+| Event | Trigger |
+|---|---|
+| `zt.membership.deactivated` | Single membership deactivated (endpoint #1) |
+| `zt.kill_switch.activated` | User kill switch triggered (endpoint #2) |
+| `zt.network_kill_switch.activated` | Network kill switch triggered (endpoint #3) |
+
+All audit entries include `organization_id`, `user_id` (the actor), `resource_type`, `resource_id`, and `metadata` (affected count, scope, network IDs).
