cproudlock 536a8f0825 Centre the parts kiosk on the screen instead of hugging the top
The kiosk runs full-screen on a wall-mounted display, where the interface sat
against the top edge with the rest of the screen empty below it. It now
centres as one block, vertically and horizontally.

The title was the other half of it: the header was space-between, which reads
as centred only on the steps that show the Start over button. On the first
step, with no button to balance it, the title sat alone at the left edge of
the column. The title is centred and Start over is taken out of the flow so it
keeps its corner without shifting the title on the steps that have it.

Centring uses `safe center`, with plain `center` as the fallback line. On a
screen too short for the content, plain `center` overflows in both directions
and the header ends up above the scroll origin, unreachable. `safe` falls back
to top-aligned there and the page scrolls normally.

Printedparts plugin

3D-printed parts inventory + kiosk checkout

This plugin was generated by flask plugin new printedparts. It satisfies the framework contract out of the box. Replace the example model and routes with your domain.

What's here

  • plugin.py - the PrintedpartsPlugin class extending BasePlugin. Edit init_app for custom setup, on_install to seed reference data.
  • models/printedparts.py - example Asset extension table. Replace examplefield with your domain fields.
  • api/routes.py - example list and detail endpoints. Add CRUD as needed.
  • schemas/__init__.py - marshmallow schema stub for request/response validation.
  • tests/test_plugin.py - smoke tests asserting contract compliance.
  • manifest.json - plugin metadata. Bump version on changes; keep core_version range broad.

Common edits

You want to... Do this
Add a hook (search, navigation, dashboard widget) Override the method in PrintedpartsPlugin. See docs/PLUGIN-HOOKS.md.
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:

  1. Decrement-only: it can reduce stock of an active item, nothing else.
  2. 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.
  3. Bounded blast radius: worst case is stock counts driven low - visible in the ledger and reversible with an adjust.
  4. 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.
