cproudlock 0f56653345 Say when a kiosk screen is not set up, and hand out the setup link
Two failures from the same root: an administrator cannot see the kiosk token,
and a screen that was provisioned wrongly does not say so.

The settings API masks every key whose name contains 'token', so the settings
page shows '********'. The real value is visible for one moment - after
Generate, before Save - and an administrator who copies the field at any other
time provisions a screen with the literal mask. The kiosk then answers 404,
exactly as it answers a caller it has never heard of, because the route
deliberately does not advertise itself. Nothing anywhere says what went wrong.

- Each kiosk gains a permission-gated provisioning-link route that returns the
  real setup URL, token included, to somebody who already holds settings.edit.
  The mask stays: a token has no business in an ordinary settings list. The
  copy step just stops depending on catching the one moment it is on screen.
  Revealing it writes an audit row, since that is when the value left the
  database. Both settings pages get a "Copy setup link" button, which falls
  back to showing the link when the clipboard is refused - it is, over plain
  http and in locked-down browsers.
- The USB kiosk asks the server on load whether this screen may be used, and
  says plainly when it may not. It rendered a keypad and only failed once
  somebody had typed their SSO, which reads as broken rather than as not set
  up. It cannot guess: the enabled flag is public and only says the site has a
  kiosk, and a caller admitted by network holds no token to look for, so the
  parts kiosk's localStorage check would warn exactly the callers the allowlist
  exists to serve. The probe is a badge-less session request - the gate runs
  before any badge handling, so refused is 404 and admitted is the validation
  error, with no lookup and nothing recorded. A test pins that ordering,
  because reordering it would start telling admitted screens they are not set
  up.

Verified in a browser, not only in tests: provisioning with the mask lands on
the refused screen, a correct token gets the drive list and survives a plain
revisit, and a tokenless caller inside the allowlist gets straight in.

USB plugin - CMMC USB check-in/out database contract

The USB plugin tracks removable-media check-in/out for CMMC compliance. Device and log state live in a separate, read-write MySQL database (cmmc_usb), reached with parameterized pymysql via cmmc_usb_connection(). Names of people are resolved from the HR employee directory (see the employees plugin).

The plugin's own reference tables (usbdevicetypes, usbdevices, usbcheckouts) live in the main app database; only the live check-in/out data is in cmmc_usb.

The schema is standardized across sites - the cmmc_usb check-in/out solution is the same deployment everywhere, so the tables below match as-is and no schema adaptation is needed. The database name may differ per site, though - set cmmc_usb_db_name (default cmmc_usb) to match the local name. The view recipe at the end is only a fallback for a site that somehow differs. (Contrast the employee directory, which genuinely varies per site.)

Connection

Credentials resolve settings-first, then environment, except the password which is env-only (never stored in the app database).

Field Setting key (editable in the setup wizard) Env var (fallback)
Host cmmc_usb_db_host CMMC_USB_DB_HOST
Database cmmc_usb_db_name CMMC_USB_DB_NAME
User cmmc_usb_db_user CMMC_USB_DB_USER
Password (not stored) CMMC_USB_DB_PASSWORD

Set the password in .env; the setup wizard's Features step shows the exact line to paste. This database is read-write - the app account needs SELECT, INSERT, UPDATE. Engine is MySQL/MariaDB (pymysql).

Required schema

The plugin runs raw SQL against these tables (or views - see below).

devices

Column Type Notes
device_id VARCHAR Primary key; the device serial/tag
device_desc VARCHAR Description
device_owner VARCHAR Owner
status VARCHAR Check-in/out state
locker_location VARCHAR Where the device is stored

Operations: SELECT (list + by id), INSERT (register device), UPDATE (edit fields, change status).

checkinoutlog

Column Type Notes
log_id INT (PK) Auto id
badge_number VARCHAR Person's badge
device_id VARCHAR FK to devices.device_id
action VARCHAR check-in / check-out
timestamp DATETIME When it happened
scanned_viruses (text/int) Scan result
locker_location VARCHAR Locker at time of event
sanitized (bool/int) Sanitization flag

Operations: SELECT (history per device), INSERT (log an event).

users

Column Type Notes
badge_number VARCHAR Primary key; the scanned badge
first_name VARCHAR Given name
last_name VARCHAR Surname

Operations: SELECT by badge, INSERT (auto-add a badge on first scan).

Employee directory dependency

To turn a scanned badge into a name, the plugin also reads the HR employees directory (via the employees plugin's connection). A badge shaped 0<digits>BZ carries a PayNo (the digits); lookups try employees.SSO and employees.PayNo. See plugins/employees/README.md for that schema and connection.

Sites whose USB-tracking database uses different table/column names should create read-only/updatable views named devices, checkinoutlog, and users that map local columns to the names above. Example:

CREATE VIEW devices AS
SELECT
  asset_tag     AS device_id,
  description   AS device_desc,
  owner         AS device_owner,
  state         AS status,
  storage_bay   AS locker_location
FROM usb_assets;

Because the plugin writes to devices/checkinoutlog/users, either make the views updatable (single-table views usually are) or expose real tables with these column names. Grant the app account SELECT, INSERT, UPDATE.

Notes:

  • device_id and badge_number are the natural keys the plugin matches on.
  • If cmmc_usb is unreachable, USB endpoints return an error and the rest of the app keeps working (the feature degrades, it does not crash the app).
