## 2. `ListContacts`

`ListContacts` использует текущую авторизованную сессию. В payload нет дополнительных полей.

### Запрос

```json
{
  "op": "ListContacts",
  "requestId": "contacts-001",
  "payload": {
  }
}
```

### Успешный ответ

```json
{
  "op": "ListContacts",
  "requestId": "contacts-001",
  "status": 200,
  "ok": true,
  "payload": {
    "login": "Alice",
    "dialogs": [
      {
        "peerLogin": "Bob",
        "relationFlag": "close_friend",
        "lastMessageBlobB64": "U0hpTkVfRE0B...",
        "lastMessageTimeMs": 1774700000123,
        "unreadCount": 2,
        "hasDialog": true
      },
      {
        "peerLogin": "Kate",
        "relationFlag": "contact",
        "lastMessageBlobB64": "",
        "lastMessageTimeMs": 0,
        "unreadCount": 0,
        "hasDialog": false
      },
      {
        "peerLogin": "Mira",
        "relationFlag": "none",
        "lastMessageBlobB64": "U0hpTkVfRE0B...",
        "lastMessageTimeMs": 1774700000555,
        "unreadCount": 1,
        "hasDialog": true
      }
    ]
  }
}
```

### Примечание

- `dialogs` это серверный inbox-проекционный список диалогов;
- `relationFlag` возвращается как `close_friend`, `contact` или `none`;
- если один и тот же человек есть и в `contact`, и в `close_friend`, в `dialogs` он приходит как `close_friend`.
- `lastMessageBlobB64` содержит полный signed DM block последнего контентного сообщения в base64;
- для чатов без сообщений поле `lastMessageBlobB64` пустое.

## 3. `GetUserConnectionsGraph`

### Запрос

```json
{
  "op": "GetUserConnectionsGraph",
  "requestId": "graph-001",
  "payload": {
    "login": "alice"
  }
}
```

### Успешный ответ

```json
{
  "op": "GetUserConnectionsGraph",
  "requestId": "graph-001",
  "status": 200,
  "ok": true,
  "payload": {
    "login": "Alice",
    "outFriends": ["Bob"],
    "inFriends": ["Kate"],
    "outContacts": [],
    "inContacts": [],
    "outFollows": [],
    "inFollows": [],
    "outSpouses": [],
    "inSpouses": [],
    "outParents": [],
    "inParents": [],
    "outChildren": [],
    "inChildren": [],
    "outSiblings": [],
    "inSiblings": [],
    "outKnownPersons": [],
    "inKnownPersons": [],
    "outShineConfirmed": [],
    "inShineConfirmed": [],
    "outShineSeen": [],
    "inShineSeen": [],
    "parents": [],
    "children": [],
    "siblings": [],
    "spouses": [],
    "allUsers": [
      {
        "login": "Bob",
        "official": false,
        "shine": true,
        "officialLabel": "",
        "shineLabel": "shine",
        "avatar": { "ar": "..." }
      }
    ]
  }
}
```

### Примечание

Поля `known_person`, `shine_confirmed`, `shine_seen` в UI считаются недопроверенной зоной проекта; при изменениях этой логики нужна ручная end-to-end проверка.

## 4. `AddCloseFriend`

`AddCloseFriend` использует текущую авторизованную сессию как источник `login`.

### Запрос

```json
{
  "op": "AddCloseFriend",
  "requestId": "close-friend-001",
  "payload": {
    "toLogin": "bob"
  }
}
```

### Успешный ответ

```json
{
  "op": "AddCloseFriend",
  "requestId": "close-friend-001",
  "status": 200,
  "ok": true,
  "payload": {
    "login": "Alice",
    "toLogin": "Bob",
    "relation": "close_friend"
  }
}
```

## 5. Profile relation lists (v18)

### `ListUserProfileRelations`

Lightweight paged lists used by clickable counters in a user profile. Supported `listType` values:

- `friends`
- `close_friends`
- `primary_received`
- `primary_given`
- `shine_received`
- `shine_given`

Request:

```json
{
  "op": "ListUserProfileRelations",
  "requestId": "profile-rel-1",
  "payload": { "login": "Alice", "listType": "friends", "limit": 100, "offset": 0 }
}
```

Each item contains a ready-to-render user card: `login`, `firstName`, `lastName`, `avatarAr`, `accountRole`, `shineStatus`, effective `relationType`, `primaryConfirmed`, `shineConfirmed`, plus received primary/shine confirmation counters.

Effective relation priority is `close_friend > friend > contact > none`. Effective `70/80` confirmations are filtered by current voting/status rules; raw blockchain connections are not deleted when temporarily ineffective.

### Voting rules

- new `80` requires the actor to have `account_role=primary`;
- `80` cannot be added to a target with `account_role=non_voting`;
- new `70` requires actor `account_role=primary` and `shine=shining` (legacy `shine=yes` is normalized to `shining`);
- `70` cannot be added to a target with `shine=not_interested`;
- a `non_voting` target may still receive `70` if its shine status allows it;
- old raw `70/80` remain in `connections_state`, but are excluded from effective lists/counts while either side is ineligible. They become effective again automatically if statuses permit later.

### `ListContacts` additions (v18)

Every dialog item now also carries `firstName`, `lastName`, `avatarAr`, `accountRole`, and `shineStatus`. `relationFlag` priority is now `close_friend > friend > contact > none`.
