A group can now be limited to a set of printers. Its members see and
control only those printers. Every other printer answers 404, as if it
didn't exist.
- Groups gain restrict_printers and a group_printers table (migration
for SQLite and Postgres). A user's printers are the union of their
limited groups. Groups without the flag don't limit anything, a user
in no limited group keeps every printer, and admins see all of them.
- core/printer_scope.py holds the scope. RequestPrinterScope and
RequirePrinterPermissionIfAuthEnabled apply it to routes: printer
routes, camera, queue and batches, archives, projects, stats, print
log, pipeline runs, inventory and Spoolman assignments, maintenance,
smart plugs, scheduled drying, firmware and Obico status.
- API keys, camera stream, Cam Wall, overlay and WebSocket tokens carry
the printers of whoever created them. WebSocket broadcasts are
filtered per connection, and the filtering fails closed.
- Scheduler: "Any <model>" jobs stay on their owner's printers. A job
pinned to a printer its owner lost waits with a reason. Callers with
no user identity and limited printers must queue to a specific printer.
- Group editor: new Printer access section, translated into all 15
locales. Saving a system group no longer resends unchanged
permissions, which the backend refused.
Cam Wall had no URL — the only way in was the toggle on the Printers page,
so it could not be bookmarked, linked, or shown on a wall-mounted screen.
Add a standalone /camwall route. Signed in, it is the wall as it was. For a
TV or Pi with no login, it authenticates with a long-lived token in the URL.
A kiosk needs the printer list and per-printer status, both of which sit
behind PRINTERS_READ. Rather than widen camera_stream to cover GET /printers
— whose response carries serial_number and ip_address, which have no business
on a screen in a shared room — add a read-only feed at
GET /api/v1/camwall/printers that serves only what a tile draws, and gate it
on a new camwall token scope. The print filename is not served at all: a token
wall renders the compact overlay, so the part on the bed is never named.
The scope is separate rather than a widening: camera_stream tokens are already
in the wild, minted to hand out video, and must not gain the ability to
enumerate a fleet by name. camera_stream is refused by the feed; camwall
passes the stream gate so its own tiles fill.
Kiosk walls drop the settings popover and click-through entirely (not merely
hidden — a passive screen must carry no focusable control it cannot act on),
cap the overlay at compact, and poll rather than open a WebSocket. maxLive,
interval and status can be set from the URL, clamped to the popover's ranges.
