# Configuration Reference

shopdb-flask reads configuration from two places, and the split is deliberate:

- **Environment variables** (`.env` / container env) hold **secrets and
  deploy-time wiring**: database credentials, signing keys, CORS origins, ports,
  API keys. These are read once at boot by `shopdb/config.py`. Never put a
  secret in the Settings table.
- **The Settings table** (seeded by `flask seed settings`, edited in the UI
  under Settings or the setup wizard) holds **site preferences**: branding,
  ServiceNow links, floor-map images, search toggles, facility identity. These
  can change at runtime without a restart and are per-instance.

Rule of thumb: if leaking it would be a security incident, it is an environment
variable. If it is a site preference an admin should be able to change in the
UI, it is a Setting.

## Part 1: Environment variables

Defined in `shopdb/config.py`. Copy `.env.example` to `.env` and fill in
values. In `production` (`FLASK_ENV=production`), `ProductionConfig.validate()`
refuses to boot if `SECRET_KEY`, `JWT_SECRET_KEY`, `DATABASE_URL`, or
`CORS_ORIGINS` are missing or set to the dev defaults.

### Flask core

| Variable | Required | Default | Notes |
|----------|----------|---------|-------|
| `FLASK_APP` | No | `wsgi.py` | Entry point for the `flask` CLI. |
| `FLASK_ENV` | Yes | `development` | `production` for live sites (triggers `validate()`). Other values: `development`, `testing`. |
| `SECRET_KEY` | Yes (prod) | dev default | Flask session/signing key. Generate: `python -c "import secrets; print(secrets.token_urlsafe(64))"`. |
| `JWT_SECRET_KEY` | Yes (prod) | dev default | JWT signing key. Different value from `SECRET_KEY`. |
| `JWT_ACCESS_TOKEN_EXPIRES` | No | `3600` | Access-token TTL in seconds. |
| `JWT_REFRESH_TOKEN_EXPIRES` | No | `2592000` | Refresh-token TTL in seconds (30 days). |
| `CORS_ORIGINS` | Yes (prod) | `http://localhost:5173` | Comma-separated explicit origins. Wildcard `*` is rejected in production. |
| `LOG_LEVEL` | No | `INFO` | Logging verbosity. |

### Database

| Variable | Required | Default | Notes |
|----------|----------|---------|-------|
| `DATABASE_URL` | Yes (prod) | dev localhost URL | `mysql+pymysql://<user>:<pass>@<host>:<port>/<db>?charset=utf8mb4`. Keep `?charset=utf8mb4`. |

### Authentication rate limiting

IP-based fixed-window limit on the login endpoint, defense-in-depth atop the
per-account lockout. Uses the existing cache extension (per-process, so the
limit is approximate across multiple gunicorn workers).

| Variable | Required | Default | Notes |
|----------|----------|---------|-------|
| `AUTH_RATELIMIT_ENABLED` | No | `True` | Set `False` to disable (TestingConfig disables it). |
| `AUTH_RATELIMIT_MAX` | No | `30` | Max login attempts per source IP per window before 429. |
| `AUTH_RATELIMIT_WINDOW_SECONDS` | No | `300` | Window length in seconds. |

### Collector ingest (ADR-006)

| Variable | Required | Default | Notes |
|----------|----------|---------|-------|
| `COLLECTOR_API_KEY` | No | (empty) | Shared key for `/api/collector/*`. Endpoint fails closed (denies) when unset and no managed token is presented. Sent as the `X-API-Key` header. |
| `COLLECTOR_API_KEY_<PLUGIN>` | No | (empty) | Per-plugin override, e.g. `COLLECTOR_API_KEY_COMPUTERS`. Checked before the shared key. |

The collector endpoints ALSO accept a managed API token (PAT) scoped to the
`collector.ingest` permission, sent in `X-API-Key` or as an
`Authorization: Bearer` token. Env keys stay supported as a bootstrap/legacy
fallback; a managed token is preferred because it is minted, rotated, and
revoked from Settings > API Tokens with `lastusedat` visibility. A
collector-scoped token is contained to the collector API and nothing else. See
`docs/COLLECTOR-INTEGRATION.md` (Managed collector tokens).

### Zabbix (printer supply monitoring)

| Variable | Required | Default | Notes |
|----------|----------|---------|-------|
| `ZABBIX_ENABLED` | No | `false` | Enable the Zabbix integration. |
| `ZABBIX_URL` | No | (empty) | Zabbix API URL. |
| `ZABBIX_TOKEN` | No | (empty) | Zabbix API bearer token. |

Note: Zabbix can also be configured via the Settings table (`zabbix_enabled`,
`zabbix_url`, `zabbix_token`). The environment values are the boot-time wiring;
prefer the Settings entries for runtime changes.

### Employee directory database (optional, read-only)

Separate HR/employee lookup DB consumed by the notifications plugin and the
public kiosks. There is no safe default for the password; an unset password
fails loud rather than trying a guessed credential.

| Variable | Required | Default | Notes |
|----------|----------|---------|-------|
| `EMPLOYEE_DB_HOST` | No | `localhost` | HR DB host. |
| `EMPLOYEE_DB_USER` | No | (empty) | HR DB user. |
| `EMPLOYEE_DB_PASSWORD` | No | (empty) | HR DB password. No safe default. |
| `EMPLOYEE_DB_NAME` | No | `wjf_employees` | HR DB name. |

Only used when `employee_directory_mode` (Setting) is `external`.

### CMMC USB database (optional, read-write)

Separate MySQL DB used by the USB plugin for check-in/out, lockers, and the log.

| Variable | Required | Default | Notes |
|----------|----------|---------|-------|
| `CMMC_USB_DB_HOST` | No | `localhost` | USB DB host. |
| `CMMC_USB_DB_USER` | No | (empty) | USB DB user. |
| `CMMC_USB_DB_PASSWORD` | No | (empty) | USB DB password. No safe default. |
| `CMMC_USB_DB_NAME` | No | `cmmc_usb` | USB DB name. |

Only used when `usb_directory_mode` (Setting) is `external`.

### docker-compose only

Read by `docker-compose.yml`, not by the Flask app directly.

| Variable | Required | Default | Notes |
|----------|----------|---------|-------|
| `MYSQL_ROOT_PASSWORD` | Yes | (none) | Root password for the bundled MySQL container. |
| `MYSQL_PASSWORD` | Yes | (none) | App-user password; must match the `DATABASE_URL` password. |
| `MYSQL_PORT` | No | `3306` | Host port for MySQL. Bound to `127.0.0.1` only. |
| `API_PORT` | No | `5001` | Host port for the API container. |

## Part 2: Settings table keys

Seeded by `flask seed settings` (idempotent; re-running adds anything missing).
Edited in the UI under Settings, or captured in the first-run setup wizard.
Values are stored as strings and typed by `valuetype`. Secrets in this table
(anything whose key contains `password`, `token`, or `secret`) are masked when
read back through the API.

### site

| Key | Default | Notes |
|-----|---------|-------|
| `setup_complete` | `false` | Set true once the first-run wizard finishes; gates the `/setup` route. |
| `employee_directory_mode` | `selfhosted` | `selfhosted` (tables in this app) or `external` (a separate HR database, see `EMPLOYEE_DB_*`). |
| `usb_directory_mode` | `selfhosted` | `selfhosted` or `external` (a separate `cmmc_usb` database, see `CMMC_USB_DB_*`). |
| `site_base_url` | (empty) | Public base URL (scheme + host) for QR codes and absolute links. Blank = use the browsing origin. |
| `facility_name` | (empty) | Facility name in the dashboard header. Blank = frontend falls back to `ShopDB`. |
| `pc_access_domain` | `device.geaerospace.net` | Domain appended to a PC hostname for remote-access links. Blank = hostname as-is. |
| `employeeid_pattern` | `^\d{9}$` | Regex a search term must match to be treated as an employee id. Invalid regex falls back to the default and never 500s. |
| `printer_hostname_template` | `Printer-{ip}.printer.geaerospace.net` | Printer hostname template. `{ip}` is the dash-separated IP address. |
| `dualpath_single_machine` | `true` | Treat a Dualpath pair (a dual-bay machine with one controller) as a single machine in the machines list, dashboard/report counts, and the floor map (the secondary bay is hidden). The data model always keeps both bay records; detail pages stay per-bay with a sibling banner. `false` lists and counts both bays separately. |

### branding

Blank values fall back to the shipped GE default asset so an un-reconfigured
install still renders. Upload replacements at Settings > Branding, which saves
them under `instance/branding/`.

| Key | Default | Notes |
|-----|---------|-------|
| `site_logo` | `/ge-aerospace-logo.svg` | Header and login-page logo. |
| `qr_logo` | `/ge-monogram.svg` | Logo composited in printer QR labels. Blank = no overlay. |
| `badge_logo` | `/ge-aerospace-logo.svg` | Logo on the machine badge print page. |
| `site_favicon` | (empty) | Browser tab favicon. Blank = shipped `/favicon.svg`. |
| `brand_primary_color` | (empty) | Primary brand color as a CSS color value (maps to `--primary`). Blank = built-in theme color. |
| `brand_primary_dark_color` | (empty) | Primary hover/active color (maps to `--primary-dark`). Blank = auto-derived by darkening the primary color ~15%. |
| `brand_accent_color` | (empty) | Accent color for secondary buttons and badges (maps to `--secondary`). Blank = built-in theme color. |
| `brand_sidebar_color` | (empty) | Sidebar background color (maps to `--sidebar-bg`). Blank = built-in theme color. |

### printing

| Key | Default | Notes |
|-----|---------|-------|
| `qr_target_printer` | (empty) | Custom URL template for printer QR labels. Blank = link to the printer page on this instance. Placeholders: `{printerid}`, `{assetid}`, `{assetnumber}`, `{serialnumber}`, `{ip}`, `{hostname}`. |
| `qr_target_usb` | (empty) | Custom URL template for USB label QR codes. Blank = link to the USB device page. Placeholders: `{id}`, `{serialnumber}`, `{alias}`. |
| `usb_label_style` | `barcode` | USB mini-label code style: `barcode` (CODE128 of the serial) or `qr` (QR code linking to the USB QR target). |

### map

| Key | Default | Notes |

| `servicenow_change_url` | geaerospaceqa.service-now.com global-search template | `{ticket}` is substituted. Replace with a direct change URL if your instance has one. |
| `zabbix_enabled` | `false` | Enable Zabbix for printer supply monitoring. |

| `smtp_use_tls` | `true` | Use TLS for the SMTP connection. |
| `smtp_from_address` | (empty) | From address for outgoing email. |
| `smtp_from_name` | `ShopDB` | From name for outgoing email. |
| `alert_recipients` | (empty) | Default alert recipients (comma-separated). |

### audit

| Key | Default | Notes |
|-----|---------|-------|
| `audit_retention_days` | `90` | Days to retain audit logs (0 = keep forever). |

### auth

| Key | Default | Notes |
|-----|---------|-------|
| `saml_enabled` | `false` | Enable SAML SSO. |
| `saml_idp_metadata_url` | (empty) | SAML IdP metadata URL. |
| `saml_entity_id` | (empty) | SAML SP entity id. |
| `saml_acs_url` | (empty) | SAML Assertion Consumer Service URL. |

| `saml_auto_create_users` | `true` | Auto-create users on first SAML login. |
| `saml_admin_group` | (empty) | SAML group name that grants the admin role. |

**Personal API tokens.** Besides login JWTs and SAML, a user may create
personal API tokens (PATs) for scripts and integrations, from Settings > API
Tokens (or `POST /api/apitokens`). A PAT is sent like a JWT
(`Authorization: Bearer shopdb_pat_...`), authenticates as its owning user
across the whole API, and does not carry the hourly `JWT_ACCESS_TOKEN_EXPIRES`
limit (it never expires unless an explicit expiry is set). Only the sha256 hash
is stored; the secret is shown once at creation. This is the recommended
credential for long-running imports (see `docs/IMPORT-API.md`). There is no env
var to configure; PATs are managed entirely through the API/UI.

Creating or managing a PAT requires the `apitokens.create` permission (admins
hold it by default; grant it to other roles from Settings > Users & Roles). By
default a PAT is unscoped and acts with the full authority of its owner. A PAT
may optionally carry a scopes list (a subset of the owner's permissions, capped
at what the owner actually holds): a scoped token grants ONLY those permissions,
intersected with the owner's live permissions at use time, and suspends the
admin bypass, so it is denied on role-gated (admin-only) endpoints and on import
mode. Use an unscoped token for admin-only work and imports.

### identifiers (dynamic)

One boolean key per asset identifier per asset type, keyed
`identifier_<name>_<assettype>_enabled` (default `true`). Admins choose which
optional identifiers show on which asset types. See ADR-001. The exact set is
generated from `IDENTIFIER_LABELS` x `IDENTIFIER_ASSETTYPES` in
`shopdb/core/api/settings.py`.

### search (dynamic)

One boolean key per search domain, keyed `search_<type>_enabled` (default
`true`). Toggles whether a domain appears in global search results. The set is
generated from `SEARCH_DOMAINS` in `shopdb/core/api/settings.py`.
