The kiosk's Settings -> Update Daemon button returned "API keys cannot
be used for administrative operations" because POST /spoolbuddy/devices/
{id}/update was gated on Permission.SETTINGS_UPDATE, and SETTINGS_UPDATE
is in the _APIKEY_DENIED_PERMISSIONS deny-list introduced by PR #1241.
Every kiosk-side request tripped the deny-list before the API key's
scope set (Read / Print Queue / Control / Legacy) was even consulted.
Same root cause as the four QuickMenu System buttons fixed in 0.2.4b3
(Restart Daemon / Restart Browser / Reboot / Shutdown). Missed /update
in that audit on the reasoning "replaces the daemon binary, different
threat surface" — but that's wrong: restart_daemon already replaces
the running daemon process, so daemon-replacement is not a step up in
blast radius. The SSH update is also strictly scoped to the one device
the operator physically controls (git fetch + pip install + systemctl
restart on that host) — same threat profile as the system commands
already running on INVENTORY_UPDATE.
Lower /spoolbuddy/devices/{id}/update from SETTINGS_UPDATE to
INVENTORY_UPDATE so it aligns with the rest of the kiosk-scoped routes
(calibration/tare, display, cancel-write, system/command,
system/command-result, update-status). The main Bambuddy in-app updater
at POST /api/v1/updates/apply keeps SETTINGS_UPDATE — that one runs on
the Bambuddy host and is correctly fenced behind the deny-list.
Seven intertwined SpoolBuddy + Spoolman bugs from feature/spoolman-inventory-ui
testing, fixed as one batch since they all live on the same path:
1. /spoolbuddy/nfc/tag-scanned always tried local DB first and only
consulted Spoolman as a fallback on local-DB miss. A stale local
row silently won over the authoritative Spoolman record. Now gates
on _get_spoolman_client_or_none() so the route uses Spoolman
exclusively when enabled, local exclusively otherwise.
2. Dashboard "Assign to AMS" button was a no-op when the matched
spool wasn't yet in the cached spools query (newly created in
Spoolman, or unarchived after page load). The card rendered via
`displayedSpool ?? sbState.matchedSpool` fallback but the modal's
stricter guard silently failed to mount. New effectiveModalSpool
synthesises an InventorySpool-shaped object from the WebSocket-
delivered MatchedSpool (9-field subset, sufficient for the modal
since it only needs `id` to route the assign API).
3. AMS-page slot picker explicitly returned null for the
assign/unassign branch when a slot had a SpoolmanSlotAssignment
but no tag-linked spool — only Configure stayed visible. Now
resolves the assignment via spoolmanSlotAssignmentsAll +
spoolmanInventorySpoolsCache, renders a "Assigned spool" info
card, and exposes an Unassign button wired to a new
unassignSpoolmanSlotMutation (DELETE
/spoolman/inventory/slot-assignments/<id>).
4. LinkSpoolModal showed "Unknown color" for every Spoolman spool
because Spoolman doesn't standardise color_name — most installs
only populate color_hex and filament.name (which often carries
the colour, e.g. "PLA Basic Red"). _map_spoolman_spool now falls
back to the filament's subtype (filament name minus material
prefix) when color_name is empty, so spools are visually
distinguishable. The NFC write-tag warning specifically checks
the raw filament.color_name (not the mapped value) so the
"tag encodes empty color name" warning still fires on installs
that genuinely lack the field.
5. Writing a tag for spool B didn't clear the same tag from spool A,
so a single NFC UID could map to two spools at once and
find_spool_by_tag returned whichever came first in the cached
list. nfc_write_result now searches Spoolman for any other spool
currently bound to the target UID and clears its extra.tag
(best-effort: cleanup failure logs a warning but doesn't block
the write, since the chip is already written).
6. The kiosk display held stale spoolmanSlotAssignments cache
permanently because a long-running browser window has no
focus/remount triggers to fire a refetch. Adds
refetchInterval: 3_000 so the kiosk picks up changes from another
client (Bambuddy main UI, direct Spoolman edit) within seconds.
7. Kiosk QuickMenu System buttons (Restart Daemon / Restart Browser /
Reboot / Shutdown) all 403'd silently. /system/command was gated
on Permission.SETTINGS_UPDATE (T-Gap 2 from a prior security
audit) but every other kiosk-scoped device route uses
INVENTORY_UPDATE; the kiosk operator's session has the latter,
not the former. Lowered to INVENTORY_UPDATE so operators can
recover the kiosk from the kiosk. Risk is bounded — only the 4
named commands are accepted (no RCE), reboot/shutdown require
physical-access recovery anyway, the same operator already
controls printers + weighs spools. /update keeps SETTINGS_UPDATE
because it can replace the daemon binary.
