-# trove
+# Trove
 
-A small web search engine.
+A federated search engine for the small web. Seeded by fediverse attention, ranked by domain coherence rather than commercial authority.
+
+## Tech stack
+
+Laravel 13 · Livewire 4 · PostgreSQL 17 (tsvector FTS) · Redis 7 · FrankenPHP · Vite 8 · Tailwind 4.
+
+## Local development
+
+Requires [Nix](https://nixos.org/download/) and [Podman](https://podman.io/).
+
+```sh
+nix-shell          # enter dev shell
+dev-up             # start app, db, redis
+```
+
+App: `http://localhost:8200` · Vite HMR: `http://localhost:5175`
+
+Other helpers inside the nix shell: `dev-down`, `dev-rebuild`, `dev-shell`, `dev-artisan <cmd>`, `dev-logs`.
+
+## Self-hosting
+
+Trove ships as a Docker image published to `forge.lvl0.xyz/lvl0/trove`. You provide the compose/stack config.
+
+### Required environment
+
+| Variable | Purpose |
+|---|---|
+| `APP_KEY` | Laravel app key. Generate with `docker run --rm forge.lvl0.xyz/lvl0/trove:latest php artisan key:generate --show`. **Must persist across deployments** or sessions/encrypted data break. |
+| `APP_URL` | Public URL, e.g. `https://trove.example.org` |
+| `DB_DATABASE`, `DB_USERNAME`, `DB_PASSWORD` | PostgreSQL credentials |
+| `DB_HOST` | Hostname of the PostgreSQL service. Default `db`. Override if your service is named differently. |
+| `REDIS_HOST` | Hostname of the Redis service. Default `redis`. Override if your service is named differently. |
+
+### Services you need to provide
+
+- **App**: pull `forge.lvl0.xyz/lvl0/trove:latest` (or a pinned `v*` tag). Exposes port `8000` inside the container. The image runs migrations and warms caches on boot.
+- **Worker**: same image as `app`, with `command: php artisan queue:work --tries=3 --max-time=3600`. Processes the crawler queue (URL fetching, content extraction, retries). Crawls won't actually run without this — `app` only enqueues work. **Required for the crawler to function.**
+- **PostgreSQL 17**. Hostname must be reachable as `db` (default) or set `DB_HOST`. Persist `/var/lib/postgresql/data`.
+- **Redis 7** with `--appendonly yes` (queue jobs persist across restarts). Hostname `redis` or set `REDIS_HOST`.
+
+On first boot the startup script waits for PostgreSQL, warms caches, then runs `php artisan migrate --force` automatically. The 60-second wait loop covers slow PG init; it exits with a clear error if PG never becomes reachable.
+
+### Volumes
+
+- `/app/storage` — Laravel writable paths (logs, cached views, uploads). Persist this.
+
+### Healthcheck
+
+The image exposes `GET /up` (Laravel's built-in health route). The Dockerfile declares a HEALTHCHECK; your orchestrator can use `curl -fsS http://localhost:8000/up` for liveness.
+
+### Example compose stack
+
+A minimal reference — adapt for your infra. DockGE, Portainer, `docker compose`, Kubernetes, and bare `podman play kube` all work with equivalent configs.
+
+```yaml
+services:
+  app:
+    image: forge.lvl0.xyz/lvl0/trove:latest
+    restart: always
+    ports: ["${APP_PORT:-8400}:8000"]

+      APP_URL: "${APP_URL}"
+      DB_DATABASE: "${DB_DATABASE}"
+      DB_USERNAME: "${DB_USERNAME}"
+      DB_PASSWORD: "${DB_PASSWORD}"
+    volumes:
+      - app_storage:/app/storage
+    depends_on:
+      db: { condition: service_healthy }

+      DB_DATABASE: "${DB_DATABASE}"
+      DB_USERNAME: "${DB_USERNAME}"
+      DB_PASSWORD: "${DB_PASSWORD}"

+      POSTGRES_USER: "${DB_USERNAME}"
+      POSTGRES_PASSWORD: "${DB_PASSWORD}"
+    volumes:
+      - db_data:/var/lib/postgresql/data
+    healthcheck:
+      test: ["CMD-SHELL", "pg_isready -U $$POSTGRES_USER -d $$POSTGRES_DB"]
+      interval: 10s
+      retries: 5
+      start_period: 10s
+
+  redis:
+    image: redis:7-alpine
+    restart: always
+    command: redis-server --appendonly yes
+    volumes:
+      - redis_data:/data
+    healthcheck:
+      test: ["CMD", "redis-cli", "ping"]
+      interval: 10s
+      retries: 5
+
+volumes:
+  db_data:
+  redis_data:
+  app_storage:
+```
+
+### Upgrades
+
+Pull the new image tag, recreate the app container. Migrations run on boot (`php artisan migrate --force` in the startup script). Rollback by pointing at the previous `v*` tag.

+            seeded by fediverse attention and ranked by domain coherence rather than
+            commercial authority. <strong>TroveBot</strong> is its crawler — it
+            discovers and indexes URLs shared by people on the fediverse, then
+            follows the citations they make to find more of the small web.
+        </p>
+
+        <h2>Identity</h2>
+
+        <p>TroveBot identifies itself with the following User-Agent string:</p>

+            <li>Follows up to 5 redirects per URL.</li>
+            <li>Fetches HTML only. PDFs, images, and other binary content are recorded as discovered but never re-fetched.</li>
+            <li>Does not execute JavaScript, does not crawl behind authentication, does not crawl URLs containing user credentials.</li>

+
+        <h2>Opt out</h2>
+
+        <p>
