+feat(spec): the push channel's protocol face, declared ahead of its producer: the widened device registration request, the stored device shape, optional `INotificationService` device members, the push delivery data with its same-server `route`, and the APNs / FCM transport configuration by `credentialRef` (ADR-0012 §6)
+
+Clause-②: yes (widening)
+Metadata-protocol: added
+
+Nothing here is served or read yet. Every new or touched schema carries a `[PLANNED — not yet served]` or `[PLANNED — not yet read]` marker in its description, and no route row is added: the device routes land in `DEFAULT_NOTIFICATION_ROUTES` together with their handlers, so the catalog never advertises a route that answers 404. Nothing a client or an operator writes today is refused.
+
+- **`RegisterDeviceRequestSchema`** gains three optional members: `vendor` (`apns` | `fcm`; absent, the server derives it from `platform`, `ios` → `apns` and `android` → `fcm`, and a `web` registration names `apns` or `fcm`), `appId` and `locale` (a BCP 47 tag, the house `LocaleSchema`). `token`, `platform`, `deviceId` and `name` are unchanged, so every body a client sent before still parses as it did. The describes now say that re-registering a `deviceId` refreshes that device, and that a request without one gets a server-minted id the client keeps. A `vendor` outside `apns` / `fcm` is refused; since the member is new, no body sent before carries one. `RegisterDeviceResponseSchema` and `UnregisterDevice*` keep their members and gain only their description.
+- **`UserDeviceSchema`** (new, `system/push-device.zod.ts`) is the stored device: `deviceId`, `userId`, `vendor`, `token`, `platform`, `enabled`, and optional `appId`, `locale`, `name`, `invalidatedAt` and `lastSeenAt`. A device belongs to its user alone (no organization member), a token has one live row (the same user's registration without a `deviceId` refreshes the row that holds it, and a second user's registration takes it over), and a token the vendor reports dead keeps its row with `enabled: false` and `invalidatedAt`.
+- **`INotificationService`** gains four optional members: `registerDevice(userId, request)`, `unregisterDevice(userId, deviceId)`, `listDevices(userId)` and `invalidateDeviceToken(token)`. Their docs state the semantics an implementation owes. Absence means the capability is unavailable, so every existing implementation stays valid.
+- **`PushDeliveryDataSchema`** (new, `api/push-delivery.zod.ts`) is the data a push carries to the shell: `notificationId` and an optional `route`. `PushRouteSchema` admits only a same-server relative path (one leading `/`; no scheme, host, backslash, whitespace or control character; no dot segment and no percent-encoded `/`, `\`, `.` or `%` in its path). The route is derived, never authored: it is the notification's existing `actionUrl` (app-relative `/OBJECT/ID` or an `/apps/…` route) when that passes the schema, and absent otherwise. The shell resolves it on tap as the inbox does, never verbatim. FCM carries this data in `message.data`; APNs at the top level of the payload, beside `aps`. No `notify` key is added.
+- **`PushServiceConfigSchema`** (new, `system/push-config.zod.ts`, beside the email transport configuration): an `apns` block (token auth: `teamId`, `keyId`, `topic`, `environment: sandbox | production`, the `.p8` key by `credentialRef`) and an `fcm` block (HTTP v1: `projectId`, the service-account JSON by `credentialRef`). Secrets are references only (ADR-0143 D3). An inline secret is refused by name under the keys an operator would reach for, and refused as the content of a reference (a PEM block or a JSON document). `PushVendorSchema` names the two vendors. It is not a stack-definition key until its reader ships.

 | :--- | :--- | :--- | :--- |

 | **name** | `string` | optional | Device friendly name |
+| **vendor** | `Enum<'apns' \| 'fcm'>` | optional | Push vendor the token belongs to: apns or fcm. Absent, the server derives it from platform: ios means apns, android means fcm. web has no default vendor: a web registration names apns or fcm, and one without vendor is refused |
+| **appId** | `string` | optional | App the token was issued to: the iOS bundle ID or the Android application ID |
+| **locale** | `string` | optional | Device locale (BCP 47, for example zh-CN) that pushes to this device are rendered in |

+
+Push delivery data — what a push carries to the shell.
+
+The shell reads it when the user taps the push: `notificationId` names the
+notification (the same id the inbox lists and `markRead` takes), and
+`route` is the notification's `actionUrl`, the link the inbox serves for it.
+
+**Where it sits in the vendor payload.** ADR-0012 §8 names it the `data`
+member of the push renderer's output; that is the renderer's shape, not the
+vendor payload. On FCM (HTTP v1) these members go in `message.data`, a map
+of string values. On APNs they sit at the top level of the payload, beside
+`aps`, and never under a `data` key.
+
+**Declared ahead of its producer.** No push channel delivers yet, so
+nothing produces this data today; `PushDeliveryDataSchema` carries a
+`[PLANNED — not yet served]` marker in its `.describe()` until the push
+channel ships. The route rule below is the contract that channel owes.
+
+**What `route` is — the inbox's `actionUrl`, derived, never authored.**
+There is no `notify` key for it. It is the value the inbox already serves:
+an explicit `url` / `actionUrl` in the notification's payload, else
+`/OBJECT/ID` built from the notification's source record, else none. So it
+is either app-relative (`/opportunity/123`) or already a Console route
+(`/apps/crm/opportunity/123`). When that value passes
+`PushRouteSchema` the push carries it as `route`; when it does not
+(an absolute URL to another site, say) or there is none, the push carries
+no `route` and the tap opens the shell's default screen. The delivery is
+never failed for it.
+
+**The shell never navigates it verbatim.** On tap it resolves `route`
+exactly as the inbox bell and Home do for the same notification: through
+`resolveNotificationTarget` (`ui/packages/app-shell/src/utils/appRoute.ts`)
+with its host app segment, which hosts an app-relative path under
+`/apps/APP/` and passes an `/apps/…` route through. One resolver, so a
+push and the inbox row open the same screen.
+
+A shell with no app list of its own (a native shell that has not loaded
+the Console's catalog, say) does not guess either. It hands `route` to the
+Console to resolve, or hosts it under the segment the Console would answer
+(`resolveHostAppSegment` in the same file: the preferred app the user last
+had open, re-checked against the active apps, then the first active app,
+then `setup`). It never re-implements the resolver and never opens `route`
+verbatim.
+
+Not to be confused with the `PushNotificationSchema` that `system/` once
+declared and then removed (ADR-0049): that was an authoring template shape;
+this is the wire data of a delivery, produced by the platform.

+## PushDeliveryData
+
+[PLANNED — not yet served] The data a push delivery carries to the shell: the notification id and its actionUrl as a same-server route. No push channel delivers yet
+
+### Properties
+
+| Property | Type | Required | Description |
+| :--- | :--- | :--- | :--- |
+| **notificationId** | `string` | ✅ | Notification id — the one the inbox lists and markRead takes |
+| **route** | `string` | optional | The notification actionUrl, the value the inbox serves, when it is a same-server relative path; absent otherwise. The shell resolves it on tap as the inbox bell and Home do, never verbatim |
+
+
+---
+
+## PushRoute
+
+The notification actionUrl as a same-server relative path: app-relative (/opportunity/123) or a Console route (/apps/crm/opportunity/123). The shell resolves it on tap as the inbox does, never verbatim; never an absolute or off-server URL
