+| `GET`  | `/api/v1/bootstrap`             | Public | `backend/src/modules/system/system.controller.ts`   |
+| `GET`  | `/api/v1/event/status`          | Public | Same.                                               |
+| `GET`  | `/api/v1/event/stream`          | Public (SSE) | Same.                                         |
+| `GET`  | `/api/v1/scoreboard/stream`     | Public (SSE) | Same.                                         |
+
+# `GET /api/v1/bootstrap`
+
+Built by `SystemService.bootstrap()`. Public payload consumed by the
+SPA's `BootstrapService`:
+
+```json
+{
+  "initialized": true,
+  "pageTitle": "HIPCTF",
+  "logo": "",
+  "welcomeMarkdown": "# Welcome\n\n...",
+  "theme": { "id": "classic", "tokens": { "...": "..." } },
+  "defaultChallengeIp": "127.0.0.1",
+  "registrationsEnabled": false
+}
+```
+
+* `initialized` is `true` iff at least one admin user exists.
+* `theme` is the resolved `Theme` (one of the 10 canonical themes; see
+  [Theming](/guides/theming.md)).
+* `registrationsEnabled` is read from the `setting` table
+  (`SETTINGS_KEYS.REGISTRATIONS_ENABLED`) and gates the new public
+  register endpoint (see [Auth Endpoints](/api/auth.md)).
+
+# `GET /api/v1/event/status`
+
+Returns the current event window computed by `EventStatusService`:
+
+```json
+{ "state": "Running", "countdownMs": 12345, "startUtc": "...", "endUtc": "..." }
+```
+
+`state` is `Stopped` when `now < eventStartUtc` (countdown), `Running`
+between start and end, and `Stopped` once `now >= eventEndUtc`.
+
+# SSE streams
+
+* `/api/v1/event/stream` — emits the same payload as
+  `GET /api/v1/event/status` whenever `SseHubService.publish` is invoked
+  (typically via an admin cron tick).
+* `/api/v1/scoreboard/stream` — emits the public scoreboard projection
+  after each new solve.
+
+Both use NestJS `@Sse()` and are proxied through `SseHubService`
+(`backend/src/common/services/sse-hub.service.ts`).
