The USB kiosk had a feature flag and nothing else. A flag is a decision, not a credential: with the kiosk on, anyone who could reach the app could move a drive between checked-out and checked-in and sign it with a badge they guessed. Same reasoning that closed the parts kiosk, smaller blast radius - which is why Darkwing did not raise it and why it was worth asking about anyway. Both kiosks now share one mechanism. The device token moved out of the printedparts api wrapper into a request interceptor that attaches X-Kiosk-Token by URL prefix, with one localStorage key per kiosk - they are separate screens in separate rooms, and a shared token would mean provisioning one grants the other. claimKioskToken() is shared too, so both views take the token from a ?token= URL once and strip it from the address bar identically. Then the part that matters more than either fix. I told you to set the new settings in the UI, and that was impossible: every plugin settings page carries a hardcoded key list, and nothing had added them. printedparts_kiosk_enabled, printedparts_kiosk_token and usb_kiosk_token were declared, seeded and read correctly, and rendered by no page - changeable only by writing SQL. tests/test_plugin_settings_reachable.py now fails when any declared setting appears nowhere in its plugin's frontend. It found seven MORE that were already in that state, all pre-existing: collector_corporate_ranges computers_configpolicies_enabled computers_machinelink_alerts computers_quietreporthours geenforce_reportstaleminutes printers_dashboardpercent warranty_expiringdays All seven now have fields. I first parked them in a KNOWN_GAPS ratchet, then fixed them and deleted the ratchet - a backlog list in a new check is a way of agreeing the check does not apply yet. There is no backlog; the check is absolute. Two of my own mistakes on the way, both caught by tests rather than by reading: the blanket rename of the USB guard also rewrote the call inside _kiosk_open, so it called itself until the stack ran out; and the first version of the reachable check skipped all 17 plugins because it looked for get_settings() when the method is get_settings_defaults() - it passed by testing nothing, which is the exact shape it exists to catch.

Common edits
| You want to... | Do this |
|---|---|
| Add a hook (search, navigation, dashboard widget) | Override the method in PrintedpartsPlugin. See the PLUGIN-HOOKS wiki page. |
| Accept external collector data | Override get_collector_schema() to return a JSON Schema. See ADR-006. |
| Add another model | Create models/<other>.py, export it in models/__init__.py, return it in get_models(). |
| Add a CLI command | Override get_cli_commands() returning a list of Click commands. |
Frontend
Vue components for this plugin live under frontend/src/views/printedparts/ (per project convention). Backend scaffolding does not generate frontend yet; copy from an existing plugin's view files (e.g., frontend/src/views/network/) as a starting point.
Install and run
flask plugin install printedparts
flask db migrate -m "Add printedparts plugin tables"
flask db upgrade
pytest plugins/printedparts/tests/

Why the kiosk take endpoint is unauthenticated
POST /api/printedparts/kiosk/take is the product's first open WRITE (every
other kiosk endpoint is a read). Accepted deliberately, against the criteria
in docs/proposals/printedparts-plugin.md:
- Decrement-only: it can reduce stock of an active item, nothing else.
- Fully attributed: it refuses to act without a badge that resolves under the site policy; every action lands in the ledger with SSO + name + time.
- Bounded blast radius: worst case is stock counts driven low - visible in the ledger and reversible with an adjust.
- Physically rate-limited: it serves a touch screen on the shop floor; nothing enumerable, nothing worth scraping.
Any future open-write endpoint must clear the same bar.
