+# Ordinis API — Quick Start
+
+Practical guide to НСИ-ordinis REST API. Тут не справочник всех endpoint'ов
+(для этого есть OpenAPI / Swagger UI), а минимально-достаточный путь от
+«первый запрос» до «подписался на webhook».
+
+**Версия:** v2.36.0 (`/api/v1`)
+**Swagger UI:** `https://ordinis.k8s.265.nstart.cloud/swagger-ui/index.html`
+(staging — на prod env-flagged)
+
+---
+
+## 0. Принципы
+
+- REST + JSON. UTF-8. Все datetime в ISO-8601 UTC (`Z` suffix).
+- Базовый префикс — `/api/v1`. Версионирование URL (breaking changes → `/v2`).
+- Auth — Keycloak OIDC, Bearer-токен в `Authorization`. Anon разрешён для
+  `PUBLIC` scope.
+- Pagination — query-params `?limit=N&offset=M`. По умолчанию `limit=50`.
+- Ошибки — `application/json` с `{status, code, message, traceId, timestamp}`.
+
+## 1. Base URL и проверка живости
+
+```bash
+# Production
+ORDINIS=https://ordinis.k8s.264.nstart.cloud
+
+# Staging
+# ORDINIS=https://ordinis.k8s.265.nstart.cloud
+
+curl "$ORDINIS/api/v1/version"
+```
+
+Ответ:
+
+```json
+{
+  "version": "0.1.0-SNAPSHOT",
+  "commit": "2ca8f053",
+  "branch": "main",
+  "tag": "v2.36.0",
+  "builtAt": "2026-05-17T08:18:07.437Z"
+}
+```
+
+## 2. Аутентификация
+
+Большинство read-эндпоинтов работают без авторизации в `PUBLIC` scope.
+Mutations, INTERNAL/RESTRICTED data, workflow и `/me/*` требуют JWT.
+
+### 2.1 Получение токена через Keycloak (password grant)
+
+```bash
+TOKEN=$(curl -s -X POST \
+  "https://auth.nstart.space/realms/nstart/protocol/openid-connect/token" \
+  -d "client_id=ordinis" \
+  -d "grant_type=password" \
+  -d "username=user@example.com" \
+  -d "password=...." \
+  -d "scope=openid profile email" \
+  | jq -r .access_token)
+```
+
+> Password grant — для CLI/CI/тестов. В production — OIDC Authorization Code
+> с PKCE через ваш BFF.
+
+### 2.2 Использование токена
+
+```bash
+curl -H "Authorization: Bearer $TOKEN" \
+  "$ORDINIS/api/v1/me/notifications/settings"
+```
+
+### 2.3 Скоупы данных
+
+- `PUBLIC` — открыто всем, включая anon
+- `INTERNAL` — только для авторизованных с ролью
+- `RESTRICTED` — узкий круг, как правило admin
+
+Sidebar и search автоматически фильтруют по scope текущей сессии.
+
+## 3. Справочники (dictionaries)
+
+### 3.1 Список всех справочников
+
+```bash
+curl "$ORDINIS/api/v1/dictionaries"
+```
+
+```json
+[
+  {
+    "id": "58ba2127-...",
+    "name": "spacecraft",
+    "displayName": "Космические аппараты",
+    "description": "Каталог КА (космических аппаратов) ДЗЗ-миссий",
+    "scope": "PUBLIC",
+    "schemaVersion": "1.0.0",
+    "bundle": "cuod",
+    "supportedLocales": ["ru-RU", "en-US"],
+    "defaultLocale": "ru-RU",
+    "createdAt": "2026-05-07T21:20:51.623195Z",
+    "updatedAt": "2026-05-07T21:20:51.623195Z"
+  },
+  ...
+]
+```
+
+### 3.2 Детали одного справочника (со схемой)
+
+```bash
+curl "$ORDINIS/api/v1/dictionaries/spacecraft"
+```
+
+`schemaJson` — полный JSON Schema draft-07 с x-расширениями:
+
+```json
+{
+  "name": "spacecraft",
+  "scope": "PUBLIC",
+  "schemaJson": {
+    "$schema": "http://json-schema.org/draft-07/schema#",
+    "$id": "https://ordinis.nstart.cloud/schemas/cuod/spacecraft/1.0.0",
+    "type": "object",
+    "required": ["designator", "name", "satellite_type_code", "status"],
+    "properties": {
+      "name": {
+        "type": "object",
+        "required": ["ru-RU"],
+        "x-localized": true,
+        "patternProperties": { "^[a-z]{2}-[A-Z]{2}$": { "type": "string" } }
+      },
+      "satellite_type_code": {
+        "type": "string",
+        "x-references": "satellite_type.code"
+      }
+    }
+  }
+}
+```
+
+### 3.3 Граф зависимостей (FK)
+
+```bash
+curl "$ORDINIS/api/v1/dictionaries/graph/outgoing"
+```
+
+```json
+{
+  "outgoing": {
+    "spacecraft": { "fkCount": 2, "targets": ["satellite_type", "spacecraft_status"] },
+    "antenna":    { "fkCount": 1, "targets": ["ground_station"] }
+  }
+}
+```
+
+## 4. Записи (records)
+
+> **Внимание к URL:** записи живут под `/api/v1/{dictName}/records`
+> (а не `/api/v1/dictionaries/{name}/records` — это путь для drafts schema'ы).
+
+### 4.1 Список записей
+
+```bash
+curl "$ORDINIS/api/v1/spacecraft/records?limit=2"
+```
+
+```json
+[
+  {
+    "id": "a211eb15-...",
+    "businessKey": "1999-068A",
+    "data": {
+      "name": "Terra (EOS AM-1)",
+      "orbit": { "type": "SSO", "inclination_deg": 98.2 },
+      "status": "OPERATIONAL",
+      "country": "US",
+      "operator": "НАСА",
+      "satellite_type_code": "OPT_MIDRES_MS"
+    },
+    "validFrom": "2026-05-08T00:00:00Z",
+    "validTo": null,
+    "dataScope": "PUBLIC"
+  }
+]
+```
+
+### 4.2 Одна запись по business key
+
+```bash
+curl "$ORDINIS/api/v1/spacecraft/records/1999-068A"
+```
+
+### 4.3 Фильтры
+
+```bash
+# По атрибутам схемы (через query-params)
+curl "$ORDINIS/api/v1/spacecraft/records?status=OPERATIONAL&country=RU"
+
+# По scope (если у тебя есть доступ к INTERNAL)
+curl -H "Authorization: Bearer $TOKEN" \
+  "$ORDINIS/api/v1/spacecraft/records?scope=INTERNAL"
+
+# Pagination
+curl "$ORDINIS/api/v1/spacecraft/records?limit=20&offset=40"
+```
+
+### 4.4 Сводка по запланированным записям
+
+```bash
+curl "$ORDINIS/api/v1/spacecraft/records/scheduled-summary"
+```
+
+```json
+{
+  "count": 0,
+  "nearestValidFrom": null,
+  "upcomingValidFroms": [],
+  "scheduledBusinessKeys": []
+}
+```
+
+## 5. Smart Search
+
+Поиск по содержимому всех справочников. Использует trigram-индекс.
+
+```bash
+curl "$ORDINIS/api/v1/search?q=Sentinel&limit=10"
+```
+
+```json
+{
+  "query": "Sentinel",
+  "total": 12,
+  "groups": [
+    {
+      "dictName": "mission",
+      "dictDisplayName": "Миссии / программы",
+      "count": 2,
+      "items": [
+        { "businessKey": "SENTINEL_1", "dataScope": "PUBLIC", "createdAt": "..." },
+        { "businessKey": "SENTINEL_2", "dataScope": "PUBLIC", "createdAt": "..." }
+      ]
+    },
+    {
+      "dictName": "instrument",
+      "dictDisplayName": "Инструменты съёмки",
+      "count": 2,
+      "items": [ ... ]
+    }
+  ]
+}
+```
+
+Минимальная длина запроса — **3 символа**. Search ограничен текущим scope сессии.
+
+## 6. Bitemporal queries (TimeTravel)
+
+### 6.1 История изменений записи
+
+```bash
+curl "$ORDINIS/api/v1/spacecraft/records/1999-068A/history"
+```
+
+Возвращает все версии (по `valid_from`) и transaction history (`system_time`).
+
+### 6.2 Snapshot справочника на дату
+
+```bash
+curl "$ORDINIS/api/v1/dictionaries/spacecraft/snapshots?asOf=2026-03-15T00:00:00Z"
+```
+
+Точная реконструкция справочника на момент `asOf`. Все записи, которые
+**действовали** (`valid_from ≤ asOf < valid_to`) и были **известны системе**
+(`system_time ≤ now()`).
+
+### 6.3 Changelog схемы (структурные изменения)
+
+```bash
+curl "$ORDINIS/api/v1/dictionaries/spacecraft/changelog?limit=10"
+```
+
+```json
+{
+  "dictionary": "spacecraft",
+  "currentVersion": "1.0.0",
+  "entries": []
+}
+```
+
+Диff между двумя версиями схемы:
+
+```bash
+curl "$ORDINIS/api/v1/dictionaries/spacecraft/changelog/{entryId}/diff"
+```
+
+## 7. Шаблоны схем
+
+```bash
+curl "$ORDINIS/api/v1/dictionaries/templates"
+```
+
+```json
+[
+  {
+    "id": "antenna",
+    "name": "Антенна",
+    "description": "Скелет: код, имя, диаметр, FK на наземную станцию.",
+    "icon": "WifiHighIcon",
+    "tags": ["space", "hardware", "cuod"]
+  },
+  { "id": "blank", "name": "Пустой каркас", ... },
+  { "id": "spacecraft", "name": "Космический аппарат", ... }
+]
+```
+
+Детали шаблона:
+
+```bash
+curl "$ORDINIS/api/v1/dictionaries/templates/spacecraft"
+```
+
+Вернёт `{ id, name, description, schemaJson }` со sample JSON Schema.
+
+## 8. AI: suggest field (требует auth)
+
+Проверка фичи:
+
+```bash
+curl "$ORDINIS/api/v1/ai/info"
+# { "enabled": true }
+```
+
+Если `enabled: false` — endpoint `/suggest-field` отдаст 404.
+
+```bash
+curl -X POST -H "Authorization: Bearer $TOKEN" \
+  -H "Content-Type: application/json" \
+  "$ORDINIS/api/v1/ai/suggest-field" \
+  -d '{"prompt": "контактный email оператора"}'
+```
+
+```json
+{
+  "fieldName": "operator_contact_email",
+  "schema": {
+    "type": "string",
+    "format": "email",
+    "description": "Контактный email оператора",
+    "x-references": "operator.code"
+  }
+}
+```
+
+**Лимиты:** 30 запросов/мин на IP. Circuit breaker открывается на 5 минут
+после 10 ошибок за 60 секунд (`503 circuit_open`).
+
+## 9. Workflow согласований (требует auth)
+
+### 9.1 Создать draft записи
+
+```bash
+curl -X POST -H "Authorization: Bearer $TOKEN" \
+  -H "Content-Type: application/json" \
+  "$ORDINIS/api/v1/dictionaries/spacecraft/records/drafts" \
+  -d '{
+    "operation": "CREATE",
+    "businessKey": "2026-099X",
+    "data": { "name": "Новый-1", "status": "PLANNED", ... },
+    "validFrom": "2026-06-01T00:00:00Z"
+  }'
+```
+
+Если `approvalRequired=true` у справочника — draft уходит ревьюеру.
+Иначе — record создаётся напрямую (если у тебя есть права).
+
+### 9.2 Мои drafts
+
+```bash
+curl -H "Authorization: Bearer $TOKEN" \
+  "$ORDINIS/api/v1/drafts/me"
+```
+
+### 9.3 Очередь ревьюера
+
+```bash
+curl -H "Authorization: Bearer $TOKEN" \
+  "$ORDINIS/api/v1/admin/reviews/pending"
+```
+
+### 9.4 Approve / reject
+
+```bash
+# Approve
+curl -X POST -H "Authorization: Bearer $TOKEN" \
+  "$ORDINIS/api/v1/drafts/{id}/approve" \
+  -d '{ "comment": "ok, merging" }'
+
+# Reject
+curl -X POST -H "Authorization: Bearer $TOKEN" \
+  "$ORDINIS/api/v1/drafts/{id}/reject" \
+  -d '{ "comment": "не хватает источника данных" }'
+```
+
+## 10. Webhooks (admin)
+
+### 10.1 Создать подписку
+
+```bash
+curl -X POST -H "Authorization: Bearer $TOKEN" \
+  -H "Content-Type: application/json" \
+  "$ORDINIS/api/v1/admin/webhooks/subscriptions" \
+  -d '{
+    "name": "my-consumer",
+    "url": "https://my-app.example.com/ordinis-hook",
+    "eventTypes": ["RecordCreated", "RecordUpdated", "SchemaDraftPublished"],
+    "scopeFilter": ["PUBLIC", "INTERNAL"],
+    "dictionaries": null,
+    "textWrap": false
+  }'
+```
+
+Ответ содержит **`secret`** — HMAC-SHA256 ключ для верификации подписи.
+Покажется один раз, сохрани.
+
+### 10.2 Структура payload (события)
+
+```json
+{
+  "eventId": "evt_01HXY...",
+  "eventType": "RecordCreated",
+  "occurredAt": "2026-05-17T13:00:00Z",

+### 10.4 Retry + DLQ
+
+Доставка ретраится с backoff (1m, 5m, 30m, 2h, 12h). После 5 неудач —
+в DLQ. Ручной retry:
+
+```bash
+curl -X POST -H "Authorization: Bearer $TOKEN" \
+  "$ORDINIS/api/v1/admin/webhooks/deliveries/{id}/retry"
+```
+
+## 11. Errors
+
+Все ошибки — JSON одинаковой формы:
+
+```json
+{
+  "status": 422,
+  "code": "validation_failed",
+  "message": "name.ru-RU is required",
+  "details": { "field": "data.name.ru-RU" },
+  "traceId": "abc123...",
+  "timestamp": "2026-05-17T13:00:00Z"
+}
+```
+
+| HTTP | code | Когда |
+|---|---|---|
+| 400 | `bad_request` | Невалидный JSON, отсутствует обязательный field |
+| 401 | `unauthorized` | Нет или просрочен токен |
+| 403 | `forbidden` | Недостаточно прав / scope |
+| 404 | `not_found` | Нет такого справочника / записи / endpoint |
+| 409 | `conflict` | Concurrent update / unique constraint |
+| 422 | `validation_failed` | Schema validation fail |
+| 429 | `rate_limited` | Превышен лимит запросов |
+| 500 | `internal_error` | Серверная ошибка (см. `traceId`) |
+| 502 | `llm_error` | AI suggest — LLM недоступен |
+| 503 | `circuit_open` | AI suggest — circuit breaker открыт |
