Whether somebody with no account may see something was being answered one feature at a time: a securesend_allow_guests setting, an enable flag per kiosk, and very nearly a third for guides - each with its own settings page, its own vocabulary and its own hand-written branch inside a route. Every one of them answered a permissions question, and this app already administers permissions per role. So a caller with no token is not nobody: they hold the seeded `guest` role. require_permission consults it when there is no identity, which is the entire mechanism. The role is seeded holding NOTHING, so an upgrade opens no door; a site opens one by ticking a box in the same grid it uses for every other role, and closes it the same way. Revocation is read on every request rather than cached, because taking guest access away is what somebody does the moment they realise what they opened, and it has to bite immediately. The redundant @jwt_required() above require_permission is gone from 184 routes. It was belt-and-braces before; now it is actively wrong, because it refuses a request with no token before the permission check can have an opinion, so a grant would appear to do nothing. What a guest may hold is bounded. Any .view or .read permission is grantable. A WRITE has to be blessed by whoever owns it, through the new get_guest_grantable_permissions hook (contract 0.21.0), and Secure Send is the only case that exists: sending a password to a vendor is the one write this product means to offer somebody who never signs in. Everything else is refused by the API and greyed out in the grid rather than warned about - a checkbox that quietly makes deleting an asset anonymous is not a warning anybody reads twice. A guest write records no creator: the trail says when and from where, never who, and that is the reason for the bar. GE-Enforce and Slides gained read permissions so they can be opened to guests without handing out the manage right. Their read routes accept either through require_any_permission, so nothing an existing manager could reach has moved. The navigation endpoint now returns only what the caller can actually reach. Without that a signed-out visitor gets a sidebar of the whole app where every link bounces off the login page, which reads as a broken site rather than as a closed door. A nav item may name several permissions; holding any one is enough, which is what GE-Enforce and Slides need now that a viewer and a manager hold different strings. Two things this found on the way: current_user is a LocalProxy, so `current_user is None` is False for a request with nobody behind it - harmless under a required JWT, an AttributeError the moment verification became optional. And an image pasted into a guide before its first save was never attached to it, so it was visible to editors and invisible to every reader; saving now attaches it, and `flask guides fix-images` repairs what is stored. The guides guest setting written earlier today is gone. Granting guides.view to the guest role replaces it, which is the point.
Printedparts plugin

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:
- 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.
