 - ⏱️ **Word-by-word highlighting** via ONNX Whisper alignment through the compute worker control plane (NATS JetStream-backed).
 - ⚡ **Segment-based read-along** for EPUB, PDF, TXT, MD, and DOCX — sentence-aware TTS with cached audio segments, background preloading, and resumable playback.
 - 🎯 **Multi-provider TTS** — self-hosted OpenAI-compatible servers (Kokoro-FastAPI, KittenTTS-FastAPI, Orpheus-FastAPI) or cloud APIs (OpenAI, Replicate, DeepInfra).
-- 🌐 **Multilingual support** — choose a document language for language-aware narration and highlighting. Available languages depend on the configured TTS provider and voice.
 - 🎧 **Audiobook export** in `m4b`/`mp3` with resumable chapter processing.
 - 🗂️ **Flexible backend** — embedded SeaweedFS or S3-compatible storage, SQLite or Postgres, server library import, and device sync.
 - 🐳 **Self-host friendly** — Docker (amd64/arm64), built-in auth/session support, and automatic startup migrations.

-
-Use [speech-sdk](https://github.com/Jellypod-Inc/speech-sdk) (Apache 2.0) to reach additional cloud TTS providers (ElevenLabs, Cartesia, Hume, Deepgram, Google Gemini TTS, Inworld, and more) with your own provider API keys. Requests go from the OpenReader server directly to the provider's API; no extra account or proxy is involved.
-
-Models use the `provider/model` format. The API key you enter belongs to the provider named by the model prefix: for `elevenlabs/eleven_multilingual_v2` enter an ElevenLabs key, for `cartesia/sonic-3.5` a Cartesia key, and so on.
-
-## Setup
-
-**Recommended (auth + admin): Settings → Admin → Shared providers**
-
-1. Add a shared provider with type `speech-sdk`.
-2. Enter the API key for the provider you want to use.
-3. Set default model to a matching `provider/model` (for example `elevenlabs/eleven_multilingual_v2`).
-
-**Per-user Settings → TTS Provider (only when `restrictUserApiKeys=false`):**
-
-1. Set provider to `Speech SDK`.
-2. Choose a model; enter the API key for that model's provider.
-3. Choose a voice.
-
-See [TTS Providers](../tts-providers) for admin-shared vs per-user behavior.
-
-## Built-in models
-
-- `openai/gpt-4o-mini-tts` (works with your existing OpenAI API key)
-- `elevenlabs/eleven_multilingual_v2`
-- `cartesia/sonic-3.5`
-- `deepgram/aura-2`
-- `google/gemini-2.5-flash-preview-tts`
-- `inworld/inworld-tts-1.5-max`
-
-You can also choose `Other` and enter any `provider/model` the SDK supports. Recognized prefixes: `openai`, `elevenlabs`, `cartesia`, `hume`, `deepgram`, `google`, `inworld`, `minimax`, `fish-audio`, `murf`, `resemble`, `fal-ai`, `mistral`, `xai`, `smallest-ai`.

-## Notes
-
-- One voice per request; Kokoro-style multi-voice mixing does not apply to this provider.
-- Playback speed is applied client-side, so cached audio segments stay valid when you change speed.
-- Providers without a built-in voice list fall back to a `default` entry, which lets the provider pick its default voice.
-- Word-by-word highlighting works the same as with every other provider (alignment runs in OpenReader, not the provider).
-- TTS requests are sent from the server, not the browser. The API key is never exposed to clients.

-title: Supertonic
----
-
-Run [Supertonic](https://github.com/supertone-inc/supertonic-py) locally and connect it to OpenReader using the `Custom OpenAI-Like` provider. Supertonic is a fast, on-device TTS engine that ships its own OpenAI-compatible HTTP server.
-
-:::note No Docker image
-Supertonic does not publish a Docker image — it installs as a Python package and runs as a local HTTP server. These instructions assume OpenReader itself runs in Docker (the common case); see [Running OpenReader directly on the host](#running-openreader-directly-on-the-host) if you don't.
-:::
-
-## Run Supertonic
-
-Install with `pip` (or `pipx` for an isolated install) and start the server:
-
-```bash
-pipx install 'supertonic[serve]'   # or: pip install 'supertonic[serve]'
-supertonic serve                   # defaults; loopback only
-```
-
-The first run downloads the model (~400MB). Once it's up, the OpenAI-compatible endpoint is at `http://127.0.0.1:7788/v1/audio/speech` and interactive docs are at `http://127.0.0.1:7788/docs`.
-
-- **Models:** `supertonic-3` (default) or `supertonic-2`.
-- **Voices:** built-ins `M1`–`M5` and `F1`–`F5`, plus any custom voices you import. OpenReader discovers them automatically via the `/v1/styles` endpoint.
-- **Audio format:** Supertonic emits `wav` by default; OpenReader transcodes it to mp3 transparently, so no extra configuration is needed.
-
-## Connect to OpenReader
-
-From a Docker container, your host machine is reachable at `host.docker.internal`, so the base URL is `http://host.docker.internal:7788/v1`. On Docker Desktop (macOS/Windows) this reaches the loopback-bound server above with no extra setup.
-
-:::note Linux (native Docker Engine)
-On native Linux Docker, `host.docker.internal` needs `--add-host=host.docker.internal:host-gateway` on the OpenReader container (or the equivalent `extra_hosts` entry in `docker-compose.yml`), and it routes to the host's bridge interface rather than loopback. Pick one:
-
-- Run the OpenReader container with `--network host` (or `network_mode: host`), keep Supertonic on `--host 127.0.0.1`, and use `http://127.0.0.1:7788/v1` as the base URL.
-- Or start Supertonic with `--host 0.0.0.0` so the bridge can reach it — keep it on a trusted network or behind a firewall.
-:::
-
-**Recommended (auth + admin): Settings → Admin → Shared providers**
-
-1. Add a shared provider with type `custom-openai`.
-2. Set base URL to `http://host.docker.internal:7788/v1`.
-3. Leave API key blank — `supertonic serve` does not require one.
-4. Set default model to `supertonic-3` (or `supertonic-2`).

-4. Choose model `supertonic-3` (or the model your deployment exposes).

-## Running OpenReader directly on the host
-

----
-title: Admin Panel
----
-
-The admin panel lets a designated set of users manage **shared TTS providers** and **site-wide feature flags** directly from the Settings modal — without touching env vars or redeploying.
-
-It is gated behind authentication, so you must have auth enabled to use it ([Auth](./auth)).
-
-## Designating admins
-
-Set `ADMIN_EMAILS` to a comma-separated list of emails:
-
-```env
-AUTH_SECRET=...        # required for auth
-BASE_URL=...           # required for auth
-ADMIN_EMAILS=alice@example.com,bob@example.com
-```
-
-On every session resolution the server compares the user's email against this list and writes `user.is_admin = true` (or `false` for emails removed from the list). No restart is required to demote — the next page load picks it up.
-
-When the logged-in user is an admin, an **Admin** tab appears in **Settings → sidebar** with two sub-tabs:
-
-- **Shared providers** — server-side TTS provider instances visible to all users.
-- **Site features** — runtime-editable replacements for what were previously build-time public env flags.
-
-## Shared TTS providers
-
-Each shared provider is one named instance bound to one of the four built-in provider types (`custom-openai`, `openai`, `replicate`, `deepinfra`). The admin form has:
-
-| Field | Notes |
-| --- | --- |
-| **Slug** | URL-safe identifier exposed to users (e.g. `kokoro-prod`). Must not collide with a built-in id. Lowercase alphanumeric + hyphens. |
-| **Display name** | Shown in the user's provider dropdown, suffixed with "(shared)". |
-| **Provider type** | One of the four built-ins. Determines voice/model resolution. |
-| **Base URL** | Optional. Falls through to the provider type's default when blank. |
-| **API key** | Encrypted at rest with AES-256-GCM (key derived from `AUTH_SECRET` via scrypt). On edit, leave blank to keep the existing key. |
-| **Default model** | Optional. Used as the initial model when a user selects this provider. |
-| **Enabled** | Toggle to hide the provider from non-admin users without deleting it. |
-
-When a non-admin user picks a shared provider in **Settings → TTS Provider**:
-
-- The API key / base URL fields are hidden — those credentials never leave the server.
-- The TTS request still goes through the user's browser, but the server replaces the slug with the matching admin row's decrypted key and base URL before calling the upstream provider.
-- The user's per-request `x-openai-key` / `x-openai-base-url` headers are ignored for shared slugs.
-
-Whether users can supply their own personal built-in provider keys is controlled by the site feature `restrictUserApiKeys`:
-
-- `true`: users are restricted to shared providers only.
-- `false`: users may also use per-user BYOK credentials for built-in providers.
-
-### Auto-seeded "default-openai"
-
-On first boot, if `admin_providers` is empty and the legacy `API_KEY` env var is set, OpenReader creates a single shared provider with:
-
-- slug `default-openai`, displayName `Default (from env)`, providerType `custom-openai`
-- baseUrl from `API_BASE`, apiKey from `API_KEY` (encrypted)
-- defaultModel set to `kokoro` (you can edit it in Admin → Shared providers)
-
-After this seed runs, the legacy `API_KEY` / `API_BASE` env vars are no longer read by the TTS routes — the DB row is authoritative. You can rename, edit, disable, or delete this row like any other from the admin UI, and remove the env vars from your `.env` when convenient.
-
-:::warning Upgrading from v2.2.0
-In v2.2.0 and earlier, `API_KEY` / `API_BASE` were read live by the TTS routes on every request. As of v3.0.0 they are **one-shot seeds** consumed only on the first boot where `admin_providers` is empty. After upgrading, boot the app once and confirm a `default-openai` row exists in **Settings → Admin → Shared providers** with the correct base URL. If it is missing or wrong (e.g. the env vars were not set on first boot, or the table was already non-empty from a pre-release), create or edit the shared provider manually — TTS will not fall back to the env vars.
-:::
-
-## Site features
-
-Runtime-editable settings, one row per key:
-
-| Key | What it controls |
-| --- | --- |
-| `defaultTtsProvider` | Default provider id new users start with (built-in id or shared slug). |
-| `changelogFeedUrl` | Public changelog manifest URL used by the Settings modal changelog panel. |
-| `enableUserSignups` | Controls whether new accounts can be created. Existing accounts can still sign in when this is `false`. |
-| `restrictUserApiKeys` | Restrict user-supplied API keys/base URLs; when `true`, only admin shared providers are allowed. |
-| `enableTtsProvidersTab` | Whether the user-facing TTS Provider tab in Settings is shown. |
-| `showAllProviderModels` | When `false`, users are restricted to each provider's default model (shared provider `defaultModel` or built-in provider default). |
-| `enableAudiobookExport` | Show the audiobook export entry points on PDF/EPUB pages. |
-| `enableDocxConversion` | Accept .docx uploads (converted to PDF server-side). |
-| `enableDestructiveDeleteActions` | Show "Delete all data" buttons in the Documents tab (auth-disabled mode). |
-
-Word-by-word highlighting and PDF layout parsing capability are controlled by compute-worker server env configuration, not an admin runtime flag.
-
-Each row shows a source badge:
-
-- **from seed** — the value was seeded on first boot (from `RUNTIME_SEED_JSON` / `RUNTIME_SEED_JSON_PATH`).
-- **admin** — explicit admin override. Use **Reset** on the row to clear it back to built-in default behavior.
-- **default** — no seed/admin row exists; built-in default is active.
-
-:::warning Security note for `restrictUserApiKeys`
-Turning `restrictUserApiKeys` off allows user-supplied API keys to flow through this server. Use this only for trusted/self-hosted deployments where that tradeoff is acceptable.
-:::
-
-## Rate limiting
-
-A dedicated **Rate limiting** group (within the same admin panel) collects the daily quotas, the PDF parsing throttle, and the upload size cap:
-
-| Key | What it controls |
-| --- | --- |
-| `disableTtsRateLimit` | Disable the per-user/IP daily TTS character limits. When `false`, the daily-limit fields below it apply. |
-| `disableComputeRateLimit` | Disable per-user PDF parsing rate limiting. When `false`, the burst/sustained limit fields below it apply. |
-| `maxUploadMb` | Maximum size (MB) accepted for a single document upload. Enforced server-side and signed into the presigned S3 PUT. |
-
-The **Disable TTS daily rate limiting** and **Disable PDF parsing rate limiting** toggles each reveal a collapsible group of numeric inputs when set to `false`:
-
-- TTS: anonymous/authenticated per-user daily limits and anonymous/authenticated IP daily backstops.
-- PDF parsing: burst limit + window (seconds) and sustained limit + window (seconds). The sustained window doubles as a concurrency cap.
-
-## TTS upstream
-
-At the end of the **Site features** tab, a dedicated **TTS upstream** group controls server-side request and cache tuning (DB-backed runtime settings, not env vars):
-
-| Key | What it controls |
-| --- | --- |
-| `ttsUpstreamMaxRetries` | Maximum retry attempts for upstream TTS 429/5xx responses. |
-| `ttsUpstreamTimeoutMs` | Upstream request timeout for OpenAI-compatible TTS calls. |
-| `ttsCacheMaxSizeBytes` | Maximum size of the in-memory TTS audio cache. |
-| `ttsCacheTtlMs` | Time-to-live for cached TTS audio buffers. |
-
-In v4 these settings are admin-only and are no longer configurable through environment variables.
-
-## Migrating off env vars
-
-In v4, runtime site features are managed by admin settings and optional JSON seed. To minimize env surface area:
-
-1. Deploy this version with your existing env values in place.
-2. Boot the app once. Open Settings → Admin and verify:
-   - Seeded settings appear as **from seed** (if you supplied a runtime JSON seed).
-   - A `default-openai` row exists in **Shared providers** (if you had `API_KEY` set).
-3. Remove any bootstrap env vars you no longer need from `.env`.
-4. Redeploy. Behavior is unchanged — the DB is now the source of truth.
-
-You can keep `API_BASE` / `API_KEY` if you intentionally want bootstrap fallback behavior on empty provider tables.
-
-## How keys are protected
-
-- API keys are encrypted in the `admin_providers` table with AES-256-GCM. The encryption key is derived from `AUTH_SECRET` via `scrypt`.
-- The masked-list view (`GET /api/admin/providers`, used by the admin UI itself) returns `••••` + last-4 only — never plaintext or ciphertext.
-- The public list endpoint (`GET /api/tts/shared-providers`, called by every user's browser) returns only `{ slug, displayName, providerType, defaultModel }`. Keys and base URLs are never exposed to the client.
-- Non-admin users cannot enumerate admin providers' credentials or base URLs through any API.
-
-:::danger Rotating `AUTH_SECRET` invalidates all stored admin provider keys
-Because the encryption key for `admin_providers` is derived from `AUTH_SECRET`, changing `AUTH_SECRET` makes every stored API key undecryptable. After rotating it, shared providers will fail to authenticate upstream until you re-enter each provider's API key in **Settings → Admin → Shared providers** (edit the row and paste the key again). There is no automated re-encryption path. If you must rotate `AUTH_SECRET`, plan to re-enter admin provider keys immediately afterward.

-title: Auth
----
-
-This page covers application-level configuration for provider access and authentication.
-
-## Auth behavior
-
-- `BASE_URL` and `AUTH_SECRET` are required at startup in v4+.
-- Keep `AUTH_TRUSTED_ORIGINS` empty to trust only `BASE_URL`.
-- Anonymous auth sessions are disabled by default.
-- Set `USE_ANONYMOUS_AUTH_SESSIONS=true` to enable anonymous session flows.
-
-## Runtime modes
-
-OpenReader has two common runtime modes:
-
-- **Auth enabled, non-admin user**: user account/session features are available, but no admin controls.
-- **Auth enabled, admin user**: full **Settings → Admin** access (shared providers + site features).
-
-## Admin role
-
-You can designate one or more users as admins via the `ADMIN_EMAILS` env var:
-
-```env
-ADMIN_EMAILS=alice@example.com,bob@example.com
-```
-
-Admins see a new **Admin** tab in **Settings** with two sub-tabs:
-
-- **Shared TTS providers** — server-managed TTS provider instances with encrypted keys, visible to all users.
-- **Site features** — runtime overrides for what were previously build-time public env flags (including account signup availability, default TTS provider, audiobook export, etc.).
-
-Admin assignment is reconciled on every session resolution, so removing an email from `ADMIN_EMAILS` demotes the user on next login without a restart. See [Admin Panel](./admin-panel) for the full reference.
-
-## Route behavior
-
-- `/` is a public landing/onboarding page and remains indexable.
-- `/app` is the protected app home (document list and uploader UI).
-- If a valid session exists (including anonymous), visiting `/` redirects to `/app`.
-- Protected app routes continue to require auth; when anonymous sessions are disabled and no session exists, users are redirected to `/signin`.

-### Auth enabled
-
-- Settings and reading progress are saved to the server.
-- Updates are not instant push-based sync; they use normal client polling/refresh behavior.
-- If two devices change the same item around the same time, the newest update wins.
-
-## Claim modal note
-
-- You may still see old anonymous settings/progress available to claim from older deployments.
-- Legacy `unclaimed` data is only surfaced through the claim flow; normal authenticated routes are scoped to your current user id.

-- Focus: SQL metadata, state, and relational tables.
-- Not covered here: object key layout and blob transport details (see [Object / Blob Storage](./object-blob-storage)).
-
-## Database mode

-## What the database stores
-
-- Document and audiobook metadata/state used by server routes.
-- Auth/session tables (`user`, `session`, `account`, `verification`) when auth is enabled — schema is auto-generated by Better Auth.
-- TTS character usage counters (`user_tts_chars`) for daily rate limiting (when enabled).
-- User settings preferences (`user_preferences`) when auth is enabled.
-- User reading progress (`user_document_progress`) when auth is enabled.
-- Document preview job/asset metadata (`document_previews`) for server-side PDF/EPUB thumbnails.
-- TTS segment metadata (`tts_segments`) for server-side playback caching:
-  - Segment identity + settings hash
-  - Audio object key and duration
-  - Optional alignment payload for word highlighting
-  - Status/error state
-  - Text fingerprint/hash (plaintext segment text is not stored)
-
-App-specific tables are manually maintained in Drizzle schema files, while auth tables are generated by the Better Auth CLI. Both are migrated together via Drizzle. See [Migrations](./migrations) for details.
-
-## What the database does not store
-

-## Startup migration behavior
-
-By default, the shared entrypoint runs migrations automatically before app startup in:
-
-- Docker container startup
-- `pnpm dev`
-- `pnpm start`
-
-Startup migration phases:
-
-- DB schema migrations (`pnpm migrate`)
-- Storage/data migration (`pnpm migrate-fs`) for legacy filesystem content into S3 + DB rows
-
-:::info
-In most setups, you do not need to run migration commands manually because startup handles this automatically.
-:::
-
-### Schema history
-
-Migrations are applied in order. All of the following ship in v3.0.0; an instance upgrading from v2.2.0 applies `0001`–`0004` in a single startup pass.
-
-| Migration | Dialects | What it does |
-| --- | --- | --- |
-| `0001_tts_segments` | SQLite + Postgres | Creates the original single-table `tts_segments` used by server-side TTS segment caching. |
-| `0002_add_segment_key_to_tts_segments` | SQLite + Postgres | Adds the `segment_key` column to `tts_segments` for stable locator-independent segment identity. |
-| `0003_tts_segments_v2_split` | SQLite + Postgres | Replaces `tts_segments` with a normalized two-table model: `tts_segment_entries` (one row per document segment + locator identity) and `tts_segment_variants` (one row per settings combination, holding the cached audio key, status, and alignment). Drops the original `tts_segments` table — no released build (v2.2.0 or earlier) ever populated it, so there is no production data to migrate. |
-| `0004_admin_panel` | SQLite + Postgres | Creates `admin_providers` (encrypted shared TTS provider rows) and `admin_settings` (runtime site-feature config), and adds the `is_admin` column to the `user` table. Backs the [Admin Panel](./admin-panel). |
-
-To skip automatic startup migrations:
-
-- Set `RUN_DRIZZLE_MIGRATIONS=false`
-- Set `RUN_FS_MIGRATIONS=false`
-
-:::warning
-If you disable startup migrations, ensure your deployment process runs migrations before serving traffic.
-:::
-
-## Apply migrations
-
-In most cases, you do not need manual migration commands because startup runs migrations automatically.
-
-`pnpm migrate` applies migrations for one database target:
-
-- Postgres when `POSTGRES_URL` is set
-- SQLite when `POSTGRES_URL` is unset
-
-You can always override the target explicitly with `--config`.

-## Generate migrations
-
-`pnpm generate` is a two-phase script for contributors and schema changes:
-
-1. **Better Auth schema generation** — runs the Better Auth CLI twice (once for SQLite, once for Postgres) to produce auto-generated Drizzle schema files for auth tables (`user`, `session`, `account`, `verification`).
-2. **Drizzle migration generation** — runs `drizzle-kit generate` for both `drizzle.config.sqlite.ts` and `drizzle.config.pg.ts`, producing SQL migration files from all schema files (app + auth).
-
-:::note
-Most users do not need to run `pnpm generate`. Use it when contributing or when you have changed Drizzle schema files and need new migration files.
-:::
-
-### Schema ownership
-
-Auth tables are owned by Better Auth. Their Drizzle schema definitions are auto-generated and should **not** be hand-edited:
-
-- `src/db/schema_auth_sqlite.ts`
-- `src/db/schema_auth_postgres.ts`
-
-App-specific tables are manually maintained in the standard Drizzle schema files:
-
-- `src/db/schema_sqlite.ts`
-- `src/db/schema_postgres.ts`
-
-Both sets of schema files are included in the Drizzle configs, so `drizzle-kit generate` and `drizzle-kit migrate` handle all tables together.
-
-When app schema changes (for example `tts_segments`), keep these in sync:
-
-- `src/db/schema_sqlite.ts`
-- `src/db/schema_postgres.ts`
-- `drizzle/sqlite/*.sql` + `drizzle/sqlite/meta/_journal.json`
-- `drizzle/postgres/*.sql` + `drizzle/postgres/meta/_journal.json`

-title: Object / Blob Storage
----
-
-import Tabs from '@theme/Tabs';
-import TabItem from '@theme/TabItem';
-
-This page documents storage backends, blob upload routing, and core Docker mount behavior.
-
-## Scope of this page
-
-- Focus: object/blob backends, keyspaces, upload/read paths, and storage debugging.
-- Not covered here: relational metadata tables and SQL state modeling (see [Database](./database)).
-
-## Storage backends
-
-- Embedded (default): embedded SeaweedFS (`weed mini`) blob storage.
-- External: external S3-compatible object storage.
-
-Metadata database mode (SQLite vs Postgres) is configured separately in [Database](./database).
-
-:::warning SeaweedFS Compatibility Note (April 16, 2026)
-OpenReader currently pins embedded SeaweedFS to `4.18` in CI and Docker builds.
-`4.19` introduced intermittent `InternalError` responses on S3 `PutObject` in our upload flow.
-:::
-
-Storage variables are documented in [Environment Variables](../reference/environment-variables#database-and-object-blob-storage).
-
-## Ports
-
-- `3003`: OpenReader app and API routes
-- `8333`: Embedded SeaweedFS S3 endpoint for direct browser blob access
-
-:::info
-`8333` is only needed for direct browser presigned access to embedded SeaweedFS.
-:::
-
-## Upload behavior
-
-- Primary path: browser uploads to presigned URL from `/api/documents/blob/upload/presign`.
-- Fallback path: `/api/documents/blob/upload/fallback` when direct upload fails/unreachable.
-- Read/download path: blob/content serving route `/api/documents/blob` (not the upload fallback route).
-- Preview path: `/api/documents/blob/preview` (returns `202` while a preview is generating; serves/redirects when ready).
-
-## Document previews
-
-- PDF/EPUB previews are generated server-side and stored in object storage under `document_previews_v1`.
-- Preview generation is triggered on upload registration and also backfills on first preview request for older docs.
-- Preview artifacts are temporary-cache friendly and can be regenerated from the source document blob.
-
-## FS / Volume Mounts
-
-### App data mount
-
-- Target: `/app/docstore`
-- Recommended: yes, for persistence
-- Purpose: persists SeaweedFS blob data, SQLite metadata DB, migrations, and local runtime temp state
-- Mount string: `-v openreader_docstore:/app/docstore`
-
-### Library source mount (optional)
-
-- Target: `/app/docstore/library`
-- Recommended: optional, use read-only (`:ro`)
-- Purpose: exposes host files as a source for server library import
-- Mount string: `-v /path/to/your/library:/app/docstore/library:ro`
-- Details: [Server Library Import](./server-library-import)
-
-## Private blob endpoint mode
-
-If `8333` is not published externally:
-
-- Document uploads still work through upload fallback proxy
-- Reads/snippets continue through app API routes
-- Direct presigned browser upload/download to embedded endpoint is unavailable
-
-:::warning
-Without `8333`, expect higher app-server traffic because uploads/downloads go through API routes instead of direct object endpoint access.
-:::

-## Audiobook Storage Debug Commands
-
-Audiobook assets are stored in object storage under the `audiobooks_v1` keyspace. Use these commands to inspect and download objects for debugging.
-
-<Tabs groupId="audiobook-storage-access-cli">
-  <TabItem value="aws-s3" label="AWS S3" default>
-
-```bash
-# List all audiobook objects

-
-## TTS Segment Storage
-
-Server-side TTS segment audio is stored in object storage under the `tts_segments_v1` keyspace.
-
-Typical key layout:
-
-- `${S3_PREFIX}/tts_segments_v1/users/<url-encoded-user-id>/docs/<document-id>/<document-version>/<settings-hash>/<segment-id>.mp3`
-- `${S3_PREFIX}/tts_segments_v1/ns/<test-namespace>/users/<url-encoded-user-id>/docs/...` (test namespace mode)
-
-Notes:
-
-- For the corresponding SQL metadata model (`tts_segments`), see [Database](./database).
-
-## Account Deletion Cleanup
-
-Account deletion performs best-effort object cleanup:
-
-- Document blobs + preview artifacts
-- Audiobook blobs
-- TTS segment blobs under `tts_segments_v1`
-
-If object deletion fails, account deletion still proceeds and orphaned objects may require manual cleanup.
-
-## TTS Segment Storage Debug Commands

-title: Server Library Import
----
-
-This page documents how server library import works and how to configure it.
-
-## What it does
-
-Server library import lets you browse files from one or more server directories and import selected files into OpenReader.
-
-- Import is user-driven via a selection modal
-- Only selected files are imported
-- Imported files become normal OpenReader documents
-
-## FS / Volume Mounts
-
-### App data mount
-
-- Target: `/app/docstore`
-- Recommended: yes, for persistence
-- Purpose: stores app runtime data, metadata DB, and embedded storage state
-- Mount string: `-v openreader_docstore:/app/docstore`
-
-### Library source mount
-
-- Target: `/app/docstore/library`
-- Recommended: yes for this feature, use read-only (`:ro`)
-- Purpose: exposes host files as import candidates in Server Library Import
-- Mount string: `-v /path/to/your/library:/app/docstore/library:ro`
-
-## Import flow
-
-1. Open **Settings -> Documents -> Server Library Import**.
-2. Select files in the modal.
-3. Click **Import**.
-
-Selected files are fetched from the server library endpoint and imported into OpenReader storage.
-
-:::warning Shared Library Roots
-Library roots are configured at the server level (not per-user). Any user who can access Server Library Import can browse/import from the same configured roots.
-
-Imported documents are still saved to the importing user's document scope.
-:::
-
-## Supported file types
-
-- `.pdf`
-- `.epub`
-- `.html`, `.htm`
-- `.txt`
-- `.md`, `.mdown`, `.markdown`
-
-## Optional: Configure Library Roots
-
-You only need this when the default mounted path is not what you want.
-
-By default, OpenReader uses `docstore/library` as the import root. You can override that with environment variables:
-
-- `IMPORT_LIBRARY_DIRS` (takes precedence): multiple roots separated by comma, colon, or semicolon
-- `IMPORT_LIBRARY_DIR`: single root
-
-See [Environment Variables](../reference/environment-variables#library-import) for variable details.
-
-## Notes
-
-- Library listing is capped per request (up to 10,000 files).
-- When auth is enabled, library import endpoints require a valid session.
-- The mounted library is a source; removing it does not delete already imported documents.
